Track daily macros against your true expenditure without arbitrary plateaus.

Understanding Macronutrients

Every calorie you consume comes from three core macronutrients: Protein, Dietary Fats, and Carbohydrates. Structuring these correctly dictates whether weight changes come from fat loss or muscle breakdown.

4 KCAL / GRAM

Protein (Essential)

Repairs muscle tissue, maximizes muscle protein synthesis (MPS), and has the highest thermic effect of food (20-30% TEF).

9 KCAL / GRAM

Fats (Essential)

Critical for hormone production (testosterone, estrogen), fat-soluble vitamin absorption (A, D, E, K), and brain health.

4 KCAL / GRAM

Carbs (Performance)

The primary fuel source for central nervous system function, anaerobic resistance training, and intramuscular glycogen.

Pairing Macro Targets with Adaptive TDEE

Tracking macros is only effective if your total daily calorie ceiling is accurate. If an online formula overestimates your TDEE by 300 calories, you will fail to lose fat even when hitting your macros perfectly.

AdapTDEE calculates your true metabolic expenditure directly from physics by analyzing daily weight trends and calorie logs.
