Protein is the nutrient that protects muscle while you lose fat, keeps you full and supports your metabolism. Here is the logic of high-protein eating, how much you need and a practical sample day.
Why protein matters so much
When you lose weight the goal is not just a lower number on the scale, it is losing fat while keeping muscle. Enough protein does that. It is also the most filling nutrient and burns slightly more energy to digest, which is why high-protein eating is a foundation for both fat loss and muscle gain.
How much protein per day?
A common guide is about 0.8-1 g per kilogram of body weight for sedentary people, and 1.2-1.6 g for those losing weight or training. For an active 70 kg person that is roughly 90-110 g a day. Needs vary; people with kidney disease should check with their doctor.
Good protein sources
| Animal | Plant |
|---|---|
| Eggs, chicken, turkey, fish, lean red meat | Lentils, chickpeas, beans, quinoa |
| Yoghurt, Greek yoghurt, kefir, cottage cheese | Tofu, edamame, nuts (measured) |
A sample high-protein day
- Breakfast: 3-egg omelette + cottage cheese + tomato
- Snack: Greek yoghurt + cinnamon
- Lunch: grilled chicken (150 g) + big salad + bulgur
- Snack: a handful of almonds + a fruit
- Dinner: baked fish + vegetables + yoghurt
The 5 most common mistakes
- Eating only protein and skipping vegetables. Fibre is still essential.
- Using shakes instead of real meals. Powder is a supplement, not the base.
- Cutting all fat and carbs. Both are needed for energy and hormones.
- Loading all protein into one meal. Spreading it across meals works better for muscle.
- Not drinking enough water. Higher protein slightly raises water needs.

Frequently asked questions
Do I need protein powder?
No. Daily protein can come from eggs, yoghurt, chicken and legumes. Powder only adds convenience.
Does high protein harm the kidneys?
In healthy kidneys, sensible amounts are not a problem. People with kidney disease should set protein with their doctor.
Can vegetarians get enough protein?
Yes - legumes, tofu, dairy and wholegrains can cover it.
