High-Protein Macro Calculator
A high-protein approach keeps protein set firmly by your bodyweight and trims fat so more of your remaining calories go to carbohydrate — useful if you train hard and want fuel for performance. This calculator estimates your TDEE and goal calories, sets protein first (0.8–1.0 g per lb depending on cut, maintain or bulk), then uses the high-protein preset to put fat at 25% of goal calories and let carbs fill the rest. The result is a diet with plenty of protein and carbs and just enough fat, shown in grams, as a percentage, and in kcal, all reconciled through the 4/4/9 rule. Enter your stats in kg/lb and cm/in, pick your goal and meals per day, and check the per-meal protein against the ≈ 0.4 g/kg muscle-protein-synthesis anchor. Protein comes from bodyweight, not a flat percentage — that is what makes it genuinely high-protein. This is a fitness estimate, not medical or dietary advice.

Frequently asked questions
What counts as a high-protein macro split?
A split where protein is set generously from bodyweight — around 1.0 g per lb — and fat is kept lower (about 25% of calories) so carbohydrate can fill the rest. It suits people who train hard and want carbs for performance while still protecting muscle. The defining feature is the protein grams, which come from your bodyweight rather than a fixed percentage of calories.
How do I hit a high protein target across the day?
Spread it across meals. Muscle-protein synthesis is maximised at roughly 0.4 g of protein per kg of bodyweight per meal, so 3–5 protein feedings usually beats one or two large ones. This calculator divides your daily protein by your meals and flags when a meal falls below that per-meal anchor.
