If you want to build muscle, lose fat or stay strong as you age, aim for about 1 gram of protein per pound of bodyweight per day. For a 180-pound person, that's about 180 grams. It's more than the official minimum, but it lines up with what research recommends for active people, and it's an easy number to remember. Here's why protein matters, why 1 gram per pound works, and the best foods to get there.
Why protein is essential
Protein is the building block of your muscles, tissues and cells. When you exercise, your muscle fibers break down, and protein is what repairs them and builds them back stronger. Beyond muscle, protein:
- Supports your metabolism. Protein has a high thermic effect: an estimated 20 to 30% of its calories are burned just digesting it, compared with about 5 to 10% for carbs and 0 to 3% for fat. Diets higher in protein raise this "diet-induced" calorie burn (Westerterp, 2004).
- Supports immune function. Antibodies, the proteins your immune system relies on, are built from the amino acids you get from protein.
- Helps make hormones and enzymes that keep your body running.
- Keeps you full. Protein is the most satisfying macronutrient, which makes it easier to eat less without feeling hungry.
How much protein do you need?
- The official minimum (RDA): 0.36 grams per pound (0.8 g per kg). It's set to prevent deficiency, not to build muscle or support an active life.
- Active people: 0.6 to 0.9 grams per pound (1.4 to 2.0 g per kg), according to the International Society of Sports Nutrition (ISSN).
- Lean, trained people who are dieting: as much as 1.0 to 1.4 grams per pound (2.3 to 3.1 g per kg) may help hold on to muscle while losing fat, per the same ISSN position stand.
That's why 1 gram per pound has become the go-to number in the fitness world: it sits at the top of the range for active people and covers you when you're cutting fat, without any complicated math.
Why 1 gram per pound is the ideal target
1. Build and repair muscle
After a workout, your muscles need protein to recover and grow. Eating enough every day, not just after training, gives your body a steady supply of building blocks.
2. Support your metabolism
Protein has a high thermic effect, meaning your body burns more calories digesting it than it does fats and carbs: roughly 20 to 30% of protein's calories, versus about 5 to 10% for carbs and 0 to 3% for fat. Muscle you build or keep also helps your body stay strong and active as you age.
3. Lose fat, keep muscle
High-protein diets help curb cravings and keep you satisfied longer. When you eat fewer calories to lose fat, plenty of protein helps your body burn fat while preserving the muscle you've worked for.
How to calculate your protein target
- Start with your bodyweight in pounds. 160 pounds = about 160 grams of protein a day.
- If you have a lot of weight to lose, many coaches use your goal weight instead. Aiming for 200 pounds? Use 200 grams.
- Split it across your meals. 3 meals plus a shake or snack makes it easy: about 40 to 50 grams per meal for most people.
The best high-protein foods
- Chicken breast, turkey and lean beef: about 25 to 35 grams per 4-ounce cooked portion
- Fish like salmon and tuna: about 25 grams per 4-ounce portion
- Eggs: about 6 grams each
- Greek yogurt: about 15 to 20 grams per cup
- Whole or raw milk: about 8 grams per cup
- Lentils and chickpeas: about 15 to 18 grams per cooked cup
- Quinoa: about 8 grams per cooked cup, a complete plant protein
Many people in the traditional-foods world favor pasture-raised meat, eggs and dairy for the most nutrient-dense protein, and round it out with beans and grains.
What 180 grams of protein looks like in a day
- Breakfast: 3 eggs and a cup of Greek yogurt (about 38 g)
- Mid-morning: coffee protein shake (about 33 g)
- Lunch: 6 ounces of chicken over greens and quinoa (about 50 g)
- Snack: beef jerky or cottage cheese (about 15 g)
- Dinner: 6 ounces of salmon or steak with vegetables (about 40 g)
Total: about 176 grams.
