The Complete Food Tracking Glossary: Every Term You Need to Know (A–Z)

Last updated: April 2026

If you have ever felt lost in a sea of acronyms while trying to understand nutrition science — TDEE, BMR, NEAT, IIFYM — you are not alone. The food tracking world moves fast, and it throws around terminology like everyone should already know it. This glossary fixes that.

What follows is a plain-English reference covering every term that actually matters when you are tracking your diet, understanding your body's energy needs, and making sense of nutrition research. Bookmark it. Share it. Come back to it whenever a term stops you in your tracks.


How to Use This Glossary

This glossary is organized alphabetically by section. Each term gets:

  • A plain-English definition — no jargon, no assumptions
  • Why it matters for tracking — the practical takeaway

If you are new to tracking, read through the whole thing. If you are looking for something specific, jump to the letter that matters. Either way, every term here is one you will encounter again and again in articles, forums, coaching programs, and tracking apps — including Minyn.


A

Adaptive Thermogenesis

Adaptive thermogenesis is your body's automatic adjustment of energy expenditure in response to changes in food intake. When you eat significantly fewer calories over an extended period, your body burns fewer calories at rest to conserve energy — it is essentially a survival mechanism kicked into gear by perceived scarcity.

This matters for tracking because it explains why weight loss often slows down or stalls even when you are doing everything right. Your BMR drops even without conscious changes in behavior. Knowing this helps you plan for plateaus instead of getting frustrated or drastically cutting calories further.

Anabolism

Anabolism is the metabolic process where your body builds and stores tissue — muscle, bone, fat, and connective tissue — using energy from the food you eat. It is the "building" side of metabolism, as opposed to the "breaking down" side (catabolism).

This matters for tracking because it tells you that your body is not just a calorie-burning machine — it is actively constructing tissue from the nutrients you provide. Whether you are building muscle, storing fat, or repairing tissue after a workout depends partly on your overall energy balance and hormonal environment.

Antinutrients

Antinutrients are compounds found naturally in some foods that interfere with the absorption or function of certain nutrients. Examples include oxalates in spinach, phytates in whole grains, and tannins in tea and coffee.

This matters for tracking when you are trying to maximize nutrient density. You do not need to avoid antinutrient-containing foods — most are healthy and the effects are usually minor — but if you rely heavily on a single food source for a specific nutrient (like iron or calcium), antinutrients may be quietly reducing how much you actually absorb.

Body Composition

Body composition is the ratio of different tissues that make up your total body weight — primarily fat mass and lean mass (muscle, bone, organs, and water). Two people at the same weight can have radically different body compositions, and therefore very different metabolic needs.

This matters for tracking because it determines how many calories your body actually burns at rest. Someone with more muscle mass has a higher BMR, even at the same weight as someone with more fat mass. If you are relying only on scale weight to measure progress, you are missing the body composition picture entirely.

BMR (Basal Metabolic Rate)

BMR is the number of calories your body burns at complete rest — just to keep your heart beating, lungs breathing, brain functioning, and cells dividing. It accounts for roughly 60 to 70 percent of your total daily energy expenditure.

This matters for tracking because it forms the foundation of any calorie calculation. Everything else — activity, exercise, digestion — gets added on top of BMR. Knowing your BMR helps you understand why a diet that works for your friend might not work for you: different bodies, different baselines.


B

Body Fat Percentage

Body fat percentage is the proportion of your total body weight that is composed of adipose tissue (body fat), as opposed to lean mass. It is expressed as a percentage — for example, 20% body fat means that 20 pounds of every 100 pounds of body weight is fat tissue.

This matters for tracking because it gives you a much more useful picture of health and fitness than weight alone. It also helps you set realistic goals. The "healthy" range differs by age and sex, but for most adults, 18–24% body fat is considered a reasonable mid-range target, while athletes and fitness-focused individuals often target lower ranges.

Bulking

Bulking is a phase where you intentionally eat in a calorie surplus — typically alongside resistance training — to maximize muscle growth. The goal is to provide your body with more energy than it needs so that the excess can be directed toward building new muscle tissue.

This matters for tracking because it requires you to track your calories and protein intake consistently. Without tracking, a "bulk" easily becomes a "dirty bulk" — excess calories going primarily to fat rather than muscle. A clean bulk keeps the surplus modest (typically 200–500 calories above maintenance) and prioritizes protein.


C

Calorie Deficit

A calorie deficit occurs when you consume fewer calories than your body burns in a day. To make up the shortfall, your body draws on stored energy — primarily body fat — to cover the difference, resulting in weight loss over time.

This matters for tracking because it is the fundamental mechanism behind fat loss. There is no special diet that works outside of a sustained calorie deficit. Understanding this does not make tracking glamorous, but it does make it effective.

Calorie Surplus

A calorie surplus is the opposite of a deficit — you are consuming more calories than your body burns. The excess energy is stored, primarily as fat, though some is used to build new muscle tissue, especially in the presence of resistance training.

This matters for tracking because if your goal is to build muscle (a "bulk"), you need to be in a surplus to provide the energy and building blocks for new tissue. The key is managing the size of the surplus: too small and muscle growth is limited; too large and you gain mostly fat.

Carbohydrates

Carbohydrates are one of the three macronutrients, providing 4 calories per gram. They are your body's preferred and most efficient source of fuel for high-intensity activity and central nervous system function. Carbohydrates are broken down into glucose, which circulates in your blood as blood sugar and is stored in your muscles and liver as glycogen.

This matters for tracking because carbohydrates are the macronutrient that most directly fuels your workouts and daily activity. How you distribute carbs across the day — around workouts, with meals, or front-loaded versus back-loaded — affects energy levels, performance, and body composition outcomes.

Catabolism

Catabolism is the metabolic process that breaks down tissue and stored nutrients to release energy. It is the opposite of anabolism. During a calorie deficit, catabolism increases as your body taps into fat stores and, in some cases, muscle tissue to fuel itself.

This matters for tracking because it explains why extreme deficits can lead to muscle loss. When caloric restriction is too aggressive, the body breaks down not just fat but also lean tissue. This is why adequate protein intake and a moderate deficit are critical for preserving muscle during fat loss.

Cortisol

Cortisol is a steroid hormone produced by the adrenal glands, often called the "stress hormone" because it spikes in response to physical and psychological stress — including sleep deprivation, intense exercise, and caloric restriction.

This matters for tracking because chronically elevated cortisol interferes with weight loss by promoting fat storage (especially around the abdomen), increasing appetite, and breaking down muscle tissue. If you are dieting hard and feeling constantly stressed, tired, and hungry, cortisol may be working against you.


D

Diet Breaks

Diet breaks are planned periods — typically 1–2 weeks — where you eat at maintenance calories (neither in deficit nor surplus) during a longer cut. Rather than dieting continuously for months, you intersperse periods of normal eating to help manage hunger, hormonal adaptations, and mental fatigue.

This matters for tracking because sustained calorie restriction causes progressive metabolic slowdown and rising hunger. A diet break resets some of those adaptations, improves adherence, and can make the overall fat loss journey shorter even though it feels counterintuitive to stop dieting.

Dysmorphia (Muscle Dysmorphia)

Muscle dysmorphia is a body image concern where someone — often experienced in fitness — fixates on the idea that they are insufficiently muscular or lean, despite evidence to the contrary. It exists on a spectrum and can drive unhealthy behaviors around food, training, and body image.

This matters for tracking when the act of logging food starts feeling like a source of anxiety, guilt, or compulsion rather than empowerment. A good tracking habit should support your goals, not consume your mental bandwidth. If tracking itself is causing distress, it is worth examining the relationship you have with the process.


E

Ectomorph

Ectomorph is a somatotype — a body type category — characterized by a lean, elongated frame, a fast metabolism, and difficulty gaining both muscle and fat. The term comes from Sheldon is constitution theory, which categorized people as ectomorph, mesomorph, or endomorph.

This matters for tracking because ectomorphs often struggle to gain weight and need higher calorie intakes to see muscle growth. The practical takeaway is that if you have always been thin, eat a lot, and struggle to gain weight, your TDEE calculation may need to start from a higher baseline than average estimates suggest.

Energy Density

Energy density refers to how many calories are packed into a given weight of food. Nuts, oils, and cheese are energy-dense — a small amount contains a lot of calories. Vegetables, fruits, and most lean proteins are low in energy density — you can eat a large volume for relatively few calories.

This matters for tracking because it directly affects how full you feel on a given number of calories. If you are always hungry on a diet, adding more low-energy-density foods — vegetables, broth-based soups, fruits — can increase meal volume without adding calories, making your deficit easier to sustain.

Essential Amino Acids

Amino acids are the building blocks of protein, and there are nine that your body cannot produce on its own — these are the essential amino acids (EAAs). You must get them from food. Animal proteins are complete sources; most plant proteins are incomplete unless combined strategically.

This matters for tracking because the quality of your protein matters as much as the quantity. If you eat a vegan or mostly plant-based diet, you need to combine protein sources to ensure you are getting all nine essential amino acids in adequate amounts for muscle protein synthesis.


F

Flex Dieting

Flex dieting is a flexible, macronutrient-focused approach to eating where food choices are not restricted by "clean" or "dirty" labels — only by whether they fit your daily or weekly macro targets. It is synonymous with IIFYM (If It Fits Your Macros).

This matters for tracking because it is one of the most sustainable approaches to dieting. Rather than following a restrictive meal plan, you track your macros and make choices within that framework. This accommodates social eating, personal preferences, and real life — which is the single biggest predictor of long-term adherence.


G

Gluconeogenesis

Gluconeogenesis is the process by which your liver produces glucose from non-carbohydrate sources — primarily amino acids, lactate, and glycerol — to keep blood sugar stable when carbohydrates are not available. It is one of the body's primary mechanisms for maintaining energy supply during fasting or very low-carb eating.

This matters for tracking because it explains why extremely low-carb diets can still maintain blood glucose levels, and why protein intake matters even on a low-carb plan. It also means that protein is not stored as efficiently as dietary carbohydrates — some of it gets redirected to glucose production rather than tissue building.

Glycemic Index

The glycemic index (GI) is a ranking of carbohydrate-containing foods based on how quickly they raise blood sugar levels. High-GI foods (white bread, watermelon, many breakfast cereals) cause a rapid spike and subsequent crash in blood sugar. Low-GI foods (most vegetables, legumes, intact grains) cause a slower, more gradual rise.

This matters for tracking because food choices within your carbohydrate allowance affect satiety, energy levels, and hunger patterns. While GI is not the only consideration — portion size and total fiber matter enormously — understanding it can help you choose carbs that keep you fuller longer and avoid energy crashes.

Glycogen

Glycogen is the storage form of glucose in your muscles and liver. Think of it as your body's short-term energy reserve. A typical adult can store roughly 300–500 grams of glycogen in muscles and another 80–100 grams in the liver, providing a readily accessible fuel source for training and daily function.

This matters for tracking because glycogen is directly tied to hydration — each gram of glycogen is stored with roughly 3–4 grams of water. When you deplete glycogen through dieting or low-carb eating, you also lose water weight. Conversely, when you refill glycogen, you retain water. This is why scale weight fluctuates significantly with changes in carbohydrate intake.


H

Ghrelin

Ghrelin is a hormone produced primarily by the stomach that signals hunger to the brain. Often called the "hunger hormone," its levels rise before meals and fall after eating. It is one of the key biological drivers of appetite, alongside leptin.

This matters for tracking because ghrelin is highly sensitive to calorie restriction. When you diet, ghrelin levels increase — you get hungrier. This is not a willpower problem; it is a hormone responding to an energy deficit. Managing ghrelin through adequate protein, fiber, strategic diet breaks, and sufficient sleep is key to sustainable fat loss.

Hydration

Hydration refers to the balance of water and electrolytes in your body — not just how much water you drink, but whether your cells and tissues have the fluid they need to function properly. Water makes up roughly 60% of your body weight and is involved in virtually every metabolic process.

This matters for tracking because water intake directly affects scale weight, exercise performance, cognitive function, and digestion. Many people are chronically underhydrated without realizing it, and mild dehydration can masquerade as hunger. Tracking water intake alongside food intake gives you a more complete picture of your nutrition status.


I

IIFYM (If It Fits Your Macros)

IIFYM is a dieting approach that focuses on meeting predetermined macronutrient targets — grams of protein, carbs, and fat — rather than eating specific "approved" foods. The guiding principle is that a nutritionally adequate diet can include any food as long as the daily macro targets are met.

This matters for tracking because it is the foundation of flexible, sustainable eating. When you understand IIFYM, you realize that meal timing, food choice, and food "quality" (within reason) are less important than consistently hitting your macro targets. It gives you freedom within a framework — which is exactly the kind of structure that works long-term.


L

Lean Body Mass (LBM)

Lean body mass is everything in your body that is not fat — muscles, bones, organs, skin, blood, and water. It is your body weight minus your body fat. For a 180-pound person at 20% body fat, LBM is 144 pounds.

This matters for tracking because LBM is what drives your metabolic rate — more muscle means a higher BMR. It also helps you set more accurate macro targets. When you calculate protein needs, you typically calculate based on LBM, not total body weight, because protein requirements are tied to your muscle mass rather than your fat mass.

Lipolysis

Lipolysis is the process by which stored body fat (triglycerides) is broken down into free fatty acids and glycerol to be used as energy. It is the primary mechanism by which your body taps into its fat stores during a calorie deficit or during periods without food.

This matters for tracking because it is the biochemical process behind fat loss. Understanding that lipolysis releases fatty acids from fat cells — which are then transported and oxidized in muscles and organs — clarifies what "burning fat" actually means at the cellular level. It is not a mystical process; it is chemistry.

Leptin

Leptin is a hormone produced by fat cells that signals satiety to the brain — essentially telling your body that it has enough energy stored. It is the counterpart to ghrelin. As body fat increases, leptin increases; as body fat decreases, leptin decreases.

This matters for tracking because low leptin levels (from prolonged dieting and fat loss) drive hunger and slow metabolism. This is one of the key mechanisms behind metabolic adaptation. Leptin is also disrupted by sleep deprivation and chronic stress, meaning that sleep and stress management are as important as food tracking for sustainable results.


M

Macros (Macro Nutrients)

Macros — short for macronutrients — are the three categories of nutrients that provide calories: protein (4 calories per gram), carbohydrates (4 calories per gram), and fat (9 calories per gram). Alcohol also provides calories (7 per gram) but is not considered a macronutrient in the nutritional sense.

This matters for tracking because hitting your macro targets is more actionable than just tracking total calories. Protein is the most important macro for body composition. Fat supports hormones. Carbohydrates fuel performance. Getting the right balance of all three is what separates a diet that works from a diet you can actually sustain.

Metabolic Adaptation

Metabolic adaptation is the collection of changes your body makes to its energy expenditure in response to altered energy intake — eating less, eating more, or changing body composition. These changes happen at the cellular, hormonal, and behavioral level and are not always fully reversible.

This matters for tracking because it is why your TDEE on paper rarely matches your TDEE in reality, especially after you have been dieting. Your body becomes more efficient, burning fewer calories for the same activities over time. This is why periodic re-calculation of your TDEE is necessary, especially after significant weight changes.

Mesomorph

Mesomorph is a somatotype characterized by a naturally muscular and athletic build, typically with broader shoulders, a narrow waist, and a relatively responsive metabolism for both gaining muscle and losing fat.

This matters for tracking because understanding that body types influence response to training and diet can help calibrate expectations. Mesomorphs typically do well on moderate calorie adjustments in either direction. However, somatotypes are spectrums, not rigid categories — most people are some combination of all three.

Micro Nutrients

Micronutrients are the vitamins and minerals your body needs in small amounts to function — iron, calcium, magnesium, zinc, vitamin D, vitamin B12, and dozens of others. Unlike macros, they provide no calories but are essential for energy production, immune function, bone health, and hundreds of enzymatic processes.

This matters for tracking because it is possible to hit your macro targets while being deficient in key micronutrients — a phenomenon called "overnutrition" or "hidden hunger." Highly processed diets can hit calorie and macro goals while leaving you micronutrient deficient. Prioritizing whole and minimally processed foods alongside your tracking ensures you are not just fed but nourished.

Myofibrillar Hypertrophy

Myofibrillar hypertrophy is the type of muscle growth that increases the actual contractile proteins (myofibrils) inside muscle fibers — making the muscle denser and stronger. This is distinct from sarcoplasmic hypertrophy, which increases the fluid and energy stores inside muscle cells.

This matters for tracking because it is the primary target of resistance training for strength and body composition. To stimulate myofibrillar hypertrophy, you need mechanical tension, progressive overload, and adequate protein — and you need to be in an energy state (usually a surplus or at least maintenance) that supports tissue building. Tracking protein intake ensures your body has the raw materials for this process.

Maintenance Calories

Maintenance calories are the number of calories you need to eat to maintain your current body weight — your body neither gains nor loses tissue. It is the midpoint between a deficit and a surplus. When someone says "eat at maintenance," they mean eating exactly what your body burns.

This matters for tracking because it is the starting point for all goal-setting. Before you know whether to cut or bulk, you need to know where maintenance sits. Most people overestimate their activity level and underestimate their intake, which is why maintenance is best estimated conservatively and adjusted over 2–4 weeks of observation.


N

NEAT (Non-Exercise Activity Thermogenesis)

NEAT is the energy your body burns through all non-exercise movement — walking to the bus, fidgeting, standing, taking the stairs, cleaning your house, and every other physical activity that is not structured exercise. It varies dramatically between individuals, sometimes by hundreds of calories per day.

This matters for tracking because NEAT is the most variable component of TDEE and the one most affected by your environment and behavior. A desk worker and a standing-desk worker can have NEAT expenditures that differ by 300 or more calories per day — a gap that completely explains why two people eating the same food lose weight at different rates.


O

Overfeeding

Overfeeding is simply eating above your maintenance calorie level — the same as a calorie surplus. In a research context, it often refers to controlled studies where participants are asked to eat well above their maintenance needs for a set period to study the effects.

This matters for tracking because the magnitude and composition of an overfeeding episode affects how much of it goes to muscle versus fat. Protein overfeeding tends to build more lean tissue; carbohydrate and fat overfeeding tends toward fat storage. For bodybuilders and athletes, strategic overfeeding (sometimes called a "refeed") is used to manage hormonal adaptations during a diet.


P

Protein Sparing Modified Fast (PSMF)

PSMF is an eating approach designed to maximize fat loss while preserving lean body mass, by eating very low calories (typically 600–800 per day) almost exclusively from protein, with minimal carbs and fat. It is essentially a prolonged fast modified to include protein to prevent muscle loss.

This matters for tracking because it sits at the extreme end of the calorie restriction spectrum. It can produce rapid fat loss results but requires careful planning to avoid micronutrient deficiencies, muscle loss, and metabolic damage. It is generally only appropriate for advanced trackers under specific circumstances and should not be attempted without adequate knowledge or supervision.

Pre-Diabetes

Pre-diabetes is a metabolic condition characterized by blood sugar levels that are elevated but not yet high enough to meet the diagnostic threshold for type 2 diabetes. It is an important warning sign and represents a window where intervention — primarily through diet and exercise — can prevent or delay progression to type 2 diabetes.

This matters for tracking because it shifts the goal from aesthetics to health markers. If you have been diagnosed with pre-diabetes or have high fasting blood sugar, tracking carbohydrate intake and prioritizing low-GI carbohydrate sources becomes especially important. Working with a healthcare provider alongside your tracking is essential in this context.


R

RMR (Resting Metabolic Rate)

RMR is the number of calories your body burns at rest — very similar to BMR, though the two are not technically identical. RMR includes some additional energy expenditure beyond strictly basal functions, such as the energy used during minor daily activities in a resting state. In practice, most calculators and fitness apps use the terms interchangeably.

This matters for tracking because RMR is the largest single component of your TDEE. Understanding that the majority of your daily calorie burn comes from simply being alive — not from exercise — helps put activity and food choices in proper perspective. You cannot out-exercise a poor diet, but you also cannot ignore the significant calorie needs of simply maintaining your body's tissues.


S

Somatic Hunger

Somatic hunger is the physical sensation of hunger that originates from actual energy needs — a genuine physiological requirement for calories. It is driven by signals like ghrelin release, blood sugar changes, and cellular energy needs, and it is felt in the body as sensations like stomach growling, lightheadedness, or low energy.

This matters for tracking because not all hunger is created equal. Emotional hunger, boredom, stress-driven eating, and habitual eating are all different from somatic hunger. Learning to distinguish somatic hunger from other types of hunger is one of the most useful skills a tracker can develop — it allows you to eat when you genuinely need fuel and resist eating when the impulse is emotional or situational.

Satiety

Satiety is the feeling of fullness and satisfaction that follows a meal, and the duration before hunger returns. Different foods produce very different satiety responses — protein and fiber tend to be highly satiating, while refined carbohydrates and fats (without protein or fiber) tend to leave you feeling less full despite similar calorie counts.

This matters for tracking because a satisfying meal is one of the strongest predictors of dietary adherence. If you are always hungry on a diet, you will eventually quit — regardless of how scientifically sound the plan is. Choosing higher-satiety foods within your macro targets is a practical strategy for making your deficit feel sustainable.

Set Point Theory

Set point theory proposes that your body has a biologically predetermined weight range that it defends through hormonal and metabolic adjustments. When you try to move significantly below this range through dieting, your body resists — increasing hunger, reducing metabolism, and slowing weight loss until you return to the range it "prefers."

This matters for tracking because it explains why long-term weight maintenance is often harder than weight loss itself. The body fights back. Understanding this is not an excuse to give up — it is a reason to plan for the long game, manage expectations, and use strategies like diet breaks, refeeds, and reverse dieting to gradually raise or stabilize your maintained weight.

Substrate Utilization

Substrate utilization refers to which fuel source your body is using at any given time — carbohydrates (glucose/glycogen), fat (fatty acids), or in extreme cases, protein (amino acids). The ratio depends on intensity and duration of activity, hormonal state, dietary intake, and training status.

This matters for tracking because your body uses different fuels at different intensities. Low-intensity activity burns mostly fat; high-intensity activity relies primarily on carbohydrates. Understanding substrate utilization helps you calibrate your carb intake around training and manage your overall energy balance more precisely.


T

TDEE (Total Daily Energy Expenditure)

TDEE is the total number of calories your body burns in a 24-hour period, accounting for all sources of energy expenditure. It includes your BMR (roughly 60–70%), the thermic effect of food (roughly 10%), exercise activity thermogenesis (highly variable), and NEAT (highly variable). TDEE is the sum of all these components.

This matters for tracking because TDEE is the number you compare against your calorie intake to determine whether you are in a deficit, surplus, or at maintenance. Every diet, every goal, every calculation starts with an honest estimate of TDEE — and since it can only be accurately measured in a lab, most people estimate and then adjust based on real-world weight change over 2–4 weeks.

Thermic Effect of Food (TEF)

TEF is the energy your body uses to digest, absorb, transport, metabolize, and store the food you eat. Different macronutrients have different TEF values: protein has the highest (roughly 20–30% of its calories are used in digestion), carbohydrates are intermediate (roughly 5–10%), and fat is the lowest (roughly 0–3%).

This matters for tracking because high-protein diets have a built-in calorie-burning advantage — roughly 100–150 extra calories per day for someone eating 150 grams of protein, just from TEF. This is one reason why adequate protein intake during a diet preserves lean mass and supports fat loss beyond what raw calorie numbers alone would suggest.

Thermodynamics and Nutrition

The laws of thermodynamics govern energy balance — energy cannot be created or destroyed, only transformed. In nutrition terms, this means that if you consume more energy than you expend, you gain weight; if you expend more than you consume, you lose weight. This is the scientific basis of calorie counting.

This matters for tracking because while the first law of thermodynamics is inviolable, the second — how your body actually partitions energy into fat, muscle, or heat — is heavily influenced by hormones, genetics, and nutritional inputs. This is why "a calorie is a calorie" is technically true in the physics sense but practically misleading: different diets produce different body composition outcomes at identical calorie levels.


U

Underfeeding

Underfeeding is a state where calorie intake falls below what the body needs for its current activity level and physiological demands — not a planned deficit for fat loss, but a chronic shortfall relative to actual needs. It can result from restrictive eating habits, skipped meals, or sustained dieting without re-calculation.

This matters for tracking because underfeeding is surprisingly common, especially among people who track inconsistently or who dramatically overestimate their TDEE. Symptoms include constant fatigue, hormonal disruption, loss of menstrual function, impaired immunity, and muscle loss. Unlike a planned deficit, underfeeding has no strategic purpose — it just Starves the body of what it needs.


W

Water Weight

Water weight refers to the volume of water your body stores, which fluctuates constantly based on carbohydrate intake, sodium consumption, hormonal changes, hydration status, and glycogen levels. A single high-carb meal can cause you to retain several pounds of water overnight.

This matters for tracking because scale weight is a terrible sole measure of progress, especially in the short term. Water weight fluctuations of 2–5 pounds in either direction are completely normal and can mask fat loss or gain on a day-to-day basis. The only meaningful weight trend to follow is the moving average over 7–14 days, not any single morning weigh-in.


How Minyn Tracks These Metrics

Minyn is built around the principle that effective tracking should be simple enough to do daily but deep enough to drive real results. Here is how Minyn handles the key metrics covered in this glossary.

Calorie and macro tracking is the foundation. Minyn lets you set personalized daily targets for calories, protein, carbohydrates, and fat based on your goal (deficit, surplus, or maintenance) and your body composition data. These targets update as you log food throughout the day.

Estimated TDEE is calculated using your entered stats — weight, height, age, sex, and activity level — and forms the baseline for your calorie target. Minyn also helps you recalibrate this estimate over time as your weight changes, accounting for metabolic adaptation.

Body composition awareness is supported through the ability to log body weight and track trends over time. While body composition analysis tools vary by platform, Minyn's focus on consistent logging helps you observe changes that go beyond the scale — especially when you account for water weight fluctuations around carb intake.

Protein tracking gets special attention because it is the most impactful macro for body composition. Minyn highlights your protein intake against your target throughout the day, making it easy to front-load protein or make up a shortfall before bed.

Hydration logging is available as a built-in tracker so you can monitor water intake alongside food and see whether adequate hydration is supporting your energy levels and digestion.

The overall philosophy is the same one behind this glossary: give you the tools and the knowledge to make sense of what you are doing, so that tracking feels less like a chore and more like a conversation with your own body.


This glossary was written to be a living reference. Bookmark it, share it, and come back whenever a term stops you. If there is a concept you think should be added, Minyn is always building out its educational content to cover what real trackers actually need to know.
