Which calculator should I start with?

  1. Find your maintenance calories with the TDEE calculator.
  2. Set a daily target with the calorie deficit calculator, and see when you would reach your goal with the weight loss date calculator.
  3. Split the target into protein, carbs and fat with the macro calculator.
  4. Check what you actually eat with the photo calorie calculator and the Indian food calorie guide.

Every calculator explains its formula and sources on its own page. The calorie, macro and goal date tools use the same equations as the Calo AI app, so your numbers match if you start tracking.
