About macros

Carbohydrates

4 kcal per gram

Frequently asked questions

Do I need to track macros?

No. Tracking is one optional tool. Many people do fine eating balanced meals without counting anything.

Why do ranges differ by style?

Different eating patterns emphasise different macronutrient splits. Choose the one that feels sustainable for you.

Can this help with weight loss?

Macro targets can help structure meals within a calorie goal, but sustainable weight loss depends on the whole pattern - food quality, sleep and activity.
