How it works

We split your daily calories by the chosen plan’s ratios, then convert to grams: protein and carbs at 4 calories per gram, fat at 9 calories per gram.

Set protein first. For fat loss while preserving muscle, 0.7 to 1 gram per pound of body weight is a widely used target. Fill carbs and fat around that number rather than splitting calories evenly from the start.

FAQs

How are macros calculated?

Daily calories are split by the plan's percentage ratios, then converted to grams using the 4-4-9 rule: protein and carbs at 4 calories per gram, fat at 9 calories per gram.

What macro split is best?

It depends on your goal. Higher protein (35 to 40 percent of calories) supports muscle retention during a cut. Keto keeps carbs to around 5 percent. A balanced split in the 25 to 30 percent protein range suits most people who are not cutting aggressively.

How much protein do I need?

Roughly 0.7 to 1 gram per pound of body weight for active people. The basic RDA of 0.36 g/lb applies to sedentary adults and is not designed to support exercise or body composition goals.

Do I need to hit macros exactly?

Get close consistently; protein and total calories matter most.

Is this medical advice?

No - consult a dietitian for personalized nutrition.
