Nutrition
Calories, macros, and how what you eat drives results.
Caloric Surplus
Eating more calories than you burn, the driver of weight and muscle gain.
Caloric Deficit
Eating fewer calories than you burn, the requirement for fat loss.
Maintenance Calories
The calorie intake at which your weight stays stable.
TDEE (Total Daily Energy Expenditure)
The total calories you burn in a day, including activity and digestion.
BMR (Basal Metabolic Rate)
The calories your body burns at complete rest to stay alive.
Macronutrients
Protein, carbs, and fat — the three nutrients that supply calories.
Protein
The macronutrient that builds and repairs muscle tissue.
Carbohydrates
The body's primary fuel source for training and daily activity.
Dietary Fat
An essential macronutrient for hormones and nutrient absorption.
Fiber
Indigestible carbohydrate that aids digestion and satiety.
Micronutrients
Vitamins and minerals your body needs in small amounts.
Glycemic Index
A ranking of how quickly carbs raise blood sugar.
Protein Timing
When you eat protein around training and across the day.
Meal Timing
How the timing of meals affects performance and body composition.
Intermittent Fasting
An eating pattern that cycles between fasting and eating windows.
Reverse Dieting
Gradually raising calories after a diet to limit fat regain.
Hydration
Maintaining fluid balance for performance and recovery.
Muscle Protein Synthesis
The process of building new muscle protein, stimulated by training and protein.
Leucine
The key amino acid that triggers muscle protein synthesis.
Essential Amino Acids (EAAs)
The nine amino acids your body can't make and must get from food.
Protein Quality
How well a protein source supplies essential amino acids and digests.
Thermic Effect of Food (TEF)
The calories burned digesting and processing what you eat.
Satiety
How full and satisfied a food makes you feel, which affects intake.
Flexible Dieting (IIFYM)
Hitting macro targets without banning specific foods.
Carb Cycling
Varying carb intake across days to match training demands.
Diet Break
A planned return to maintenance calories during a long diet.
Electrolytes
Minerals like sodium and potassium that drive hydration and muscle function.
Omega-3 Fatty Acids
Essential fats linked to recovery, heart, and brain health.
Added Sugar
Sugars added to foods, a common source of empty calories.
Alcohol & Fitness
How alcohol affects recovery, muscle building, and fat loss.
