How much protein per day to lose weight?
Of all the variables in a weight loss plan, protein intake has the largest impact on results. It's not about eating less — it's about eating the right type of food that keeps you full and preserves your muscle while fat is being lost.
Why protein matters so much in a calorie deficit
- Satiety: Protein activates hunger-suppressing hormones (GLP-1, PYY) more powerfully than carbs or fat. High protein meals keep you full for longer, making a calorie deficit easier to sustain.
- Muscle preservation: During a calorie deficit, your body can break down muscle for fuel. Adequate protein intake prevents this, preserving the muscle that keeps your metabolism elevated.
- Thermic effect: Your body burns approximately 25% of protein calories just digesting them — versus 5–10% for carbs and 0–3% for fat. Protein is metabolically expensive to process.
How much protein do you need per day to lose weight?
The evidence-based target for fat loss is 1.6–2.2g of protein per kg of bodyweight per day. Higher intakes (up to 2.2g/kg) are beneficial if you're exercising or at risk of significant muscle loss.
| Your weight | Minimum (1.6g/kg) | Optimal (2.0g/kg) |
|---|---|---|
| 55 kg | 88g/day | 110g/day |
| 65 kg | 104g/day | 130g/day |
| 75 kg | 120g/day | 150g/day |
| 85 kg | 136g/day | 170g/day |
| 95 kg | 152g/day | 190g/day |

Calculate my protein target →Practical tips for hitting your protein target
- Include a protein source in every meal — don't rely on one large protein meal to hit your target
- Greek yoghurt, cottage cheese, or boiled eggs work well as high-protein snacks
- Protein powder is a convenient supplement — not essential but useful if whole foods aren't meeting your target
- Cook in bulk: batch-cooked chicken, lentil dal, or boiled eggs make hitting daily targets much easier
Key takeaways
- Aim for 1.6–2.2g of protein per kg of bodyweight per day when losing weight.
- For a 70 kg person, that's 112–154g of protein daily.
- Protein keeps you full, preserves muscle, and burns more calories to digest.
- Include a protein source in every meal rather than relying on one large serving.
- Meeting your protein target matters more than any specific food choice.
