How much protein makes sense?

The German Nutrition Society (DGE) gives 0.8 g of protein per kilogram of body weight a day for adults under 65.[1]

The reference values

GroupValue per dayType of value
19 to under 65 years0.8 g/kg[1]Recommended intake, DGE
65 years and over1.0 g/kg[1]Estimated value, DGE
Adults0.83 g/kg[2]EFSA reference value

Example: at 70 kg, 0.8 g/kg comes to about 56 g of protein a day.[1]

With overweight, meaning a BMI over 25, DGE says to base the calculation on normal weight, not on current weight.[1] DGE gives separate values for pregnancy and breastfeeding.

What these values do not say

Reference values describe adequate supply, not weight loss. They say nothing about whether more protein helps you lose weight.

How the app handles this

Entering protein is optional, and the app sets no target for it. If you state diabetes or kidney disease in the safety questions, you do not see the protein way. This only means the feature is missing and is no recommendation for another way. In that case, talk to your doctor.

The app does not replace medical advice.
