How much protein do I need to lose fat?

Higher protein intakes help protect muscle and control appetite while dieting. A widely used range is roughly 1.6 to 2.2 g per kilogram of bodyweight per day, spread across your meals. Sit towards the upper end if you are lean and training hard in a deficit.

Why protein rises when calories fall

In a deficit your body is looking for energy, and muscle protein is one of the available sources. A higher protein intake combined with resistance training tips that balance towards keeping lean tissue and losing fat instead. This is the single most useful nutritional adjustment when dieting.

The appetite benefit

Protein is the most filling of the three macronutrients for a given number of calories. Building each meal around a solid protein source usually makes the same calorie target feel considerably less restrictive, which matters more for the outcome than any subtle metabolic effect.

Practical targets

• 80 kg: Roughly 130 to 175 g per day.
• 65 kg: Roughly 105 to 145 g per day.
• Higher body fat: Basing the calculation on a target or lean bodyweight avoids inflating the number unnecessarily.
• Distribution: Three to five meals with 25 to 45 g each.

Filling the target

Lean meat, fish, eggs, dairy, soy, legumes, and protein powder all count. In a deficit, leaner sources let you fit more food volume into the calories available, which helps with fullness. Greek yoghurt, cottage cheese, white fish, chicken breast, tofu, and lentils are all efficient choices.

What protein will not do

It does not create a deficit by itself, and eating well above the range does not accelerate fat loss. Total calories remain the deciding factor; protein determines how much of the loss comes from fat rather than muscle.

Anyone with kidney disease or another condition affecting protein handling should get individual advice from a doctor or registered dietitian before raising intake. More on the training side of muscle retention is in Hypertrophy and Muscle Growth.
