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.
