Calorie and macro calculators
BMR, TDEE, protein, carbs, fat, and daily calorie targets.
Most people do not need a new diet. They need a calorie range that matches their size and activity, then a protein number they can hit on ordinary food.
These calculators share one energy engine: Mifflin-St Jeor for resting burn, an activity multiplier for daily burn, then a goal adjustment with an educational calorie floor. Macros are layered on after the calorie number exists.
Pick the tool that matches the question you actually typed into search. The calorie calculator answers “how much should I eat.” TDEE answers “how much do I burn.” BMR answers “what does my body use at rest.”
Calorie Calculator
Estimate a daily calorie target from body size, activity, and goal.
TDEE Calculator
Estimate the calories that hold your current weight at the activity you actually live — optional daily steps included.
BMR Calculator
Estimate basal metabolic rate with Mifflin-St Jeor and a Harris-Benedict comparison.
Macro Calculator
Split a calorie target into protein, carbohydrate, and fat grams.
Protein Calculator
Set a daily protein target from body weight and whether you are maintaining, training, building, or cutting.
Carbohydrate Calculator
Turn a calorie budget into carbohydrate grams for low, moderate, high, or endurance-style eating.
Fat Intake Calculator
Convert a calorie target and a fat percentage into daily fat grams.
Intermittent Fasting Calculator
Map 14:10, 16:8, 18:6, or 20:4 onto your wake time so the eating window is a clock.
Fiber Intake Calculator
Blend the 14 g per 1,000 kcal rule with Adequate Intake values by sex.
PSMF Calculator
See a high-protein, low-carb planning sketch — with calories held at Protealpes’ educational floor.
Carnivore Macro Calculator
Set calories from TDEE, protein from body weight, incidental carbs, and fat to fill the rest.
PCOS Calorie Calculator
A milder deficit from the same TDEE math, plus a higher-protein cue — not a PCOS treatment.
Net Carb Calculator
Subtract fiber and sugar alcohols from total carbohydrate for an Atkins-style net-carb count.
