How much protein do lifters and runners need?
If you train regularly, you need more protein than the basic recommendation for sedentary adults, but probably less than gym folklore suggests. Here is what the research says and how to hit it with ordinary food.
The short version
- Most people who train do well on about 1.6 g of protein per kilogram of body weight per day; 1.4 to 2.0 g/kg is the commonly recommended range.
- Spread it over three or four meals of roughly 25 to 40 grams each.
- The daily total matters more than the exact timing around workouts.
- Aim higher, toward 2.0 g/kg, while eating in a calorie deficit.
The number
The general recommendation for adults is 0.8 grams of protein per kilogram of body weight per day. That is enough to avoid deficiency, not to support hard training.
For people who lift, a 2018 meta-analysis by Morton and colleagues, pooling 49 trials and nearly 1,900 people, found that the benefit of extra protein for muscle gain leveled off at about 1.6 g per kilogram per day, with some people benefiting up to around 2.2 g/kg. The International Society of Sports Nutrition recommends 1.4 to 2.0 g/kg per day for most exercising people.
| Body weight | 1.6 g/kg per day | 2.0 g/kg per day |
|---|---|---|
| 55 kg | 88 g | 110 g |
| 70 kg | 112 g | 140 g |
| 85 kg | 136 g | 170 g |
| 100 kg | 160 g | 200 g |
Endurance athletes land in a similar range, commonly 1.2 to 1.6 g/kg on normal days. Hybrid athletes, who do both, do well aiming for about 1.6 g/kg and going higher when they are eating less to lose fat, since protein helps keep muscle in a calorie deficit.
Spread it across the day
Your body uses protein better in several decent servings than in one huge one. A practical target is about 0.3 to 0.4 g/kg per meal across three or four meals: roughly 25 to 40 grams each for most adults. A serving after training is useful, but the daily total matters more than exact timing.
What that looks like on a plate
Some everyday foods and roughly how much protein a typical serving gives you:
| Food | Serving | Protein |
|---|---|---|
| Chicken breast | 150 g cooked | about 45 g |
| Greek yogurt | 200 g | about 20 g |
| Eggs | 3 large | about 19 g |
| Paneer | 100 g | about 18 g |
| Lentil dal | 1 bowl | about 12–15 g |
| Tofu | 150 g | about 18–20 g |
| Whey protein | 1 scoop (30 g) | about 24 g |
| Tuna | 1 can, drained | about 25 g |
Values vary by brand and recipe. Check the label, or log the dish in a tracker that uses realistic servings.
Easy ways to get more
- Build each meal around a protein first, then add carbohydrate and vegetables.
- Make breakfast count: eggs, Greek yogurt, cottage cheese or a protein smoothie instead of only toast or cereal.
- Keep easy snacks around: yogurt, milk, roasted chickpeas, edamame, jerky or a protein bar.
- If you eat plant-based, combine sources over the day (beans, lentils, tofu, tempeh, seitan, soy milk) and aim toward the top of the range.
Who should check with a professional
People with kidney disease, and anyone with a medical condition or on a prescribed diet, should talk to a doctor or registered dietitian before increasing protein. This guide is general information, not medical advice.

Is 1 gram of protein per pound too much?
One gram per pound is about 2.2 g/kg, the top of the range where research still sees some benefit. It is not harmful for healthy people, but most will get the same results from around 1.6 g/kg.
Do runners need protein?
Yes. Runners commonly need 1.2 to 1.6 g/kg per day to repair muscle and adapt to training, more than the 0.8 g/kg general recommendation.
Can I get enough protein without supplements?
Yes. Supplements are a convenience. Three or four meals built around eggs, dairy, meat, fish, tofu, lentils or beans can reach the target.
