Nutrition calculators
The same math that runs inside Food Loops, on the open web. No account, no email, nothing stored — the numbers are worked out in your browser and forgotten when you close the tab.
TDEE & Macros
Maintenance calories from the Mifflin-St Jeor equation, then the protein, carb and fat grams to go with your goal.
Satiety Score
Score any food 0–100 on how filling it is per calorie. Weighs protein, fiber, energy density and palatability.
Goal Weight Date
When you'll reach your goal weight at a given pace, and the daily calorie gap that pace costs.
BMI & Ideal Weight
BMI, Devine-formula ideal body weight, and the healthy weight range for your height.
Why these agree with the app
Every formula here is ported directly from the Food Loops source, with a comment in the code naming the file it came from. That matters more than it sounds: most calculators on the web quietly disagree with each other because they round differently, use a different BMR equation, or anchor protein to current weight rather than goal weight.
These give you the same answer the app would. If you later install it, nothing you worked out here changes.
Stop doing this by hand
The app does all of this continuously, against what you actually ate — and updates as your weight changes.
