Protein needs vary by age, health, activity, body composition, and individual circumstances.
How Much Protein Do You Need Every Day?
Protein is an essential nutrient that supports muscle maintenance, tissue repair, immune function, and many important processes throughout the body.
The Recommended Dietary Allowance (RDA) for most healthy adults is approximately 0.8 grams of protein per kilogram of body weight daily. This is a baseline recommendation, not necessarily the optimal amount for every individual.
People who exercise regularly, train for muscle growth, or have certain nutrition goals may benefit from higher protein intake.
How Is Protein Intake Calculated?
Daily protein estimates are commonly calculated by multiplying body weight in kilograms by a protein factor expressed in grams per kilogram.
Daily Protein (grams) = Body Weight (kg) × Protein Factor
Should You Spread Protein Across Meals?
Distributing protein throughout the day can make it easier to meet your daily intake. This calculator divides your estimated protein target evenly across your selected number of meals.
Protein-Rich Foods to Add to Your Diet
Both animal-based and plant-based foods can help you meet your protein needs.
| Food | Approximate Protein |
|---|---|
| Chicken Breast, Cooked (3 oz) | 26 g |
| Large Egg (1) | 6 g |
| Greek Yogurt, Plain (6 oz) | 15–18 g |
| Salmon, Cooked (3 oz) | 22 g |
| Lentils, Cooked (1 cup) | 18 g |
| Firm Tofu (3 oz) | 8–15 g |
| Cottage Cheese (1/2 cup) | 12–14 g |
Values are approximate and vary by brand, preparation method, and serving size.
