The tools
Three calculations, no account and no cap. What they have in common is the thing the category leaves out most often: the equation that gets applied is named, dated and sourced, and nothing typed in ever leaves the browser.
A day's calorie needs and how they split into protein, carbs and fat, for losing weight, holding steady, or gaining.
Mifflin-St Jeor rather than Harris-Benedict, the equation named and sourced, and the calorie floor both applied and stated.
OpenBody mass index, the WHO category it falls into, and the weight range that matches a normal build for a given height.
All eight WHO categories where the category shows four, and waist circumference, which almost no calculator asks for.
OpenThe three historical formulas side by side, dated, and the weight range that really does match a normal build.
They are shown disagreeing, with the gap measured, rather than one of them printed alone as though it settled the question.
OpenThe food pages give the calories and macros of 60 everyday items, by real serving rather than per hundred grams, from the Ciqual table published by the Anses, the French food safety agency.
These calculators apply published equations to typed measurements. They replace neither a doctor nor a dietitian, and they do not suit pregnancy, breastfeeding, a chronic condition, or an eating disorder.
