Macros for fat loss

Updated June 3, 2026

Fat-loss macros work best when they are simple enough to repeat. Start with a reasonable calorie deficit, set protein, keep fats adequate, and let carbohydrates fill the remaining calories.

Calories come first

Macro percentages do not create fat loss by themselves. The calorie target is the main lever. A moderate deficit is usually easier to sustain than an aggressive one.

Protein supports the plan

Higher protein can help with fullness and lean-mass support during a deficit. TDEE Lab uses a higher protein bias for fat-loss targets, but the result is still a planning estimate.

Carbs and fats can flex

Once calories and protein are set, carbs and fats can move based on preference, training, digestion, and food choices. You do not need to hit exact carb and fat grams every day.

Use the macro calculator or estimate the deficit with the calorie deficit calculator.
