Calorie and Nutrition Calculators

Free tools with instant results and no sign-up. All of them rest on the same published formulas, and each page states its sources openly.

Calorie Calculator Work out your daily calorie and macro targets from your age, height, weight and activity. Photo Calorie Counter How calorie estimation from a food photo works, and how far you can trust it. TDEE Calculator Work out how many calories you burn in a day at your activity level. BMR Calculator Find the energy your body uses at complete rest. Calorie Deficit Calculator See the daily deficit needed to reach your goal weight in your timeframe. Macro Calculator Split your daily calories into protein, carbs and fat in grams. Protein Calculator Work out your daily protein from your weight and training status.

Why are these tools free?

The calculators are EatLog's shop window. Finding your calorie target is the first step of nutrition tracking, and we give that step away free and without an account. For the second step — daily tracking — you can try the app. But the tools work fully without installing anything; no result is locked.
