How macros are calculated

  1. We find your daily calories: your TDEE (Mifflin-St Jeor BMR × activity), minus 500 kcal to lose weight or plus 300 kcal to gain.
  2. We split those calories by your chosen diet style.
  3. We convert to grams: protein and carbohydrates have 4 kcal per gram; fat has 9 kcal per gram.

Which split should I choose?

Frequently asked questions

What is the best macro ratio for weight loss?

Calories matter most. A higher protein share (25–30%) helps you feel full and keep muscle while losing fat.

How many grams of protein should I eat?

For most active adults trying to lose fat or build muscle, 1.6–2.2 g per kg of body weight. See the protein calculator for your exact range.

Can vegetarians hit high protein macros?

Yes. Combine dal, paneer, curd, soya chunks, tofu, milk and sprouts across the day; a protein supplement can help if needed.

Is keto safe?

Keto can work short term for some people, but it is restrictive. People with diabetes, kidney disease or who are pregnant should talk to a doctor first.
