GLP-1 Protein and Fibre Calculator

GLP-1 Protein and Fibre Calculator

If set and lower than your weight, protein is sized from it.

Used only to check that a goal weight is not in the underweight range.

Your usual intake, not a target. Protein is capped at 40% of calories.

General nutrition information, not medical advice. Ask your prescriber or a registered dietitian what fits you. Nothing here tells you what to do about a medicine.

Protein is sized from your current weight of 90.0 kg. Spread across 5 small meals, that is about 25 g of protein each.

Raise fibre gradually and drink fluids with it. Very high fibre in one go can be uncomfortable when you eat little.

Ask your prescriber or a dietitian before changing how you eat.
