How to Calculate Ideal Protein Intake
Quick Answer
| Goal | Protein Target (per kg body weight) |
|---|---|
| General health (sedentary adults) | 0.8 g/kg |
| Active adults and regular exercisers | 1.2 to 1.6 g/kg |
| Muscle building (resistance training) | 1.6 to 2.2 g/kg |
| Fat loss while preserving muscle | 1.8 to 2.4 g/kg |
| Athletes in heavy training | 2.0 to 3.0 g/kg |
Example: 75 kg person wanting to build muscle. Protein target = 75 × 1.8 = 135 g per day (up to 75 × 2.2 = 165 g per day).

Protein Content of Common Foods
| Food | Protein Content | Notes |
|---|---|---|
| Chicken breast (100 g cooked) | 31 g | Low fat, high protein |
| Beef (100 g lean, cooked) | 26 to 30 g | Higher fat than chicken |
| Eggs (1 large) | 6 g | Complete amino acid profile |
| Whole milk (200 ml) | 7 g | Also contains fat and carbs |
| Greek yogurt (150 g) | 15 to 20 g | Good low-calorie protein source |
| Paneer (100 g) | 18 to 20 g | Popular in Indian and Pakistani diets |
| Dal or lentils (1 cup cooked) | 18 g | Plant-based, incomplete protein |
| Chickpeas (1 cup cooked) | 15 g | Plant-based protein and fibre |
| Whey protein (30 g scoop) | 20 to 25 g | Convenient post-workout |
| Fish (salmon, 100 g cooked) | 25 g | Also high in omega-3 |
Protein Requirements by Population Group
- Sedentary adults (WHO minimum): 0.8 g/kg. Minimum to prevent deficiency.
- Recreationally active adults: 1.2 to 1.6 g/kg. Supports muscle maintenance with moderate exercise.
- Bodybuilders and strength athletes: 1.6 to 2.2 g/kg. Maximises muscle protein synthesis.
- Adults over 65: 1.0 to 1.2 g/kg minimum. Higher protein needs due to anabolic resistance.
- Fat loss phase: 1.8 to 2.4 g/kg. Higher end protects muscle during calorie restriction.
Protein Intake by Country and Diet Type
- India (vegetarian and vegan): Plant-based proteins from dal, paneer, curd, chickpeas, soya and nuts. Consciously increasing dal, paneer and dairy intake helps reach 1.2 to 1.6 g/kg targets.
- Pakistan: Dal, chicken, mutton and fish are main protein sources. Urban professionals increasingly use whey protein supplements for convenience.
- United Kingdom: Meat, fish, dairy and eggs are dominant protein sources. UK dietary guidelines recommend 0.75 g/kg but research supports higher amounts for active adults.
- United States: USDA recommends 10 to 35% of calories from protein.
Frequently Asked Questions
How much protein do I need to build muscle?
Research consistently shows that 1.6 to 2.2 g of protein per kg of body weight per day is sufficient for maximising muscle protein synthesis in resistance-trained adults. Going above 2.2 g/kg provides no additional muscle-building benefit.
Can I get enough protein without eating meat?
Yes. Focus on dal, legumes, paneer, curd, tofu, tempeh, seitan and quinoa (a complete protein). Combining rice and dal in a meal provides a near-complete amino acid profile.
Is too much protein harmful for kidneys?
For healthy adults with normal kidney function, high protein intake is not harmful to the kidneys according to current evidence. The concern applies only to people with pre-existing kidney disease.
