Macros describe the protein, fat and carbohydrates in a food. FATSL usually shows them per 100 g so you can compare foods at the same weight.
Overview
A clear explanation of the value and what it means.
Macros describe the protein, fat and carbohydrates in a food. FATSL usually shows them per 100 g so you can compare foods at the same weight.
How it is calculated
The formula or method behind the calculation.
If a food contains 22.5 g of protein per 100 g, a 150 g serving contains 33.75 g of protein.
FATSL leaves the result unavailable if an input is missing or a zero value would require division by zero.
Example
A worked example using a food in the FATSL reference guide.
The chicken breast entry lists calories, protein, fat and carbs per 100 g. Multiply each value by your portion weight divided by 100.
| Example | kcal | Protein | Fat | Carbs | 100 g | 100 kcal | 10 g protein |
|---|---|---|---|---|---|---|---|
| Chicken breast | 120,0 kcal | 22,5 g | 2,6 g | 0,0 g | no data | no data | no data |
