Formula

Use E = 4P+4C+9F. P, C and F na grams of protein, available carbohydrate and fat. Estimated energy E dey for kcal, with general food-label factors.

Convert protein, carbohydrate and fat grams wey you enter to food-label-style energy.

Example wey show the calculation

Amount of protein (g): 30
Carbohydrate wey body fit use (g): 50
Amount of fat (g): 10

Energy wey model estimate: 410 kcal
Energy from protein: 120 kcal
Energy from carbohydrate: 200 kcal
Energy from fat: 90 kcal

Where e fit work and limits

General 4/4/9 factors; fibre, sugar alcohols, organic acids and food-specific factors fit differ. E no recommend macro targets.

We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.

Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
