In weight loss and diabetes, protein matters for fullness, maintaining muscle and organising meals. This means balanced planning, not an extreme high-protein diet.
Why does protein help?
A meal with protein, vegetables and carbohydrates containing fibre usually provides better fullness than a meal high in sugar or refined starches. During weight loss, protein and strength exercises help limit muscle loss.
If you are at a weight-loss plateau, the first step is not to cut calories drastically, but to check protein, fibre, steps, sleep and adherence.
Good protein sources
- eggs, fish, lean meat, Greek yoghurt and suitable cheeses;
- lentils, beans, chickpeas, soya and tofu;
- nuts and seeds in moderate portions;
- plant-based combinations of wholegrains and pulses.
If you have kidney disease, pregnancy, digestive disorders or complex treatment, the protein amount needs to be determined medically.
Protein and glucose
Protein does not replace carbohydrate management, but can make meals more stable. A breakfast consisting only of white bread and jam may affect glucose differently from a meal containing an egg, yoghurt or pulses. For examples, see the diabetes nutrition plan.
During Wegovy or Mounjaro treatment
When appetite drops, some people eat too little and lose muscle. In weight-loss programmes, protein, hydration, fibre and strength exercises therefore need to be discussed explicitly.
A personalised nutrition plan can set realistic portions adapted to test results and treatment.
