Calculating Your Daily Protein Needs
Understanding how many grams of protein you need if you weigh 150 pounds requires moving beyond a single, generic number and considering your lifestyle. While the minimal RDA provides a baseline, a more personalized calculation will help you optimize your intake for your specific goals, from maintaining a sedentary lifestyle to building serious muscle mass.
First, you must convert your weight from pounds to kilograms to use many common formulas. At 150 pounds, you weigh approximately 68 kilograms (150 / 2.2 = 68.2 kg). With this number, you can easily calculate a more specific target range based on your activity and goals.
Sedentary Individuals
For a sedentary person, the minimum protein intake is around 0.8 grams per kilogram of body weight, which is approximately 54 grams daily for a 150-pound (68 kg) individual. This minimum is primarily to prevent deficiency.
Active Individuals and Athletes
Recommendations range from 1.4–2.0 grams per kilogram of body weight for active individuals, depending on intensity. For a 150-pound person, this translates to 82 to 116 grams daily for moderate activity and 109 to 150 grams for intense training.
Protein for Weight Loss
Protein is important for preserving lean muscle during a calorie deficit and increases satiety. An intake of 1.6 to 2.2 grams per kilogram, or 109 to 150 grams per day for a 150-pound person, is often recommended for weight loss.
Sources of Protein to Meet Your Goals
Spread protein intake throughout the day with 20-30 grams per meal or snack.
Animal-Based Sources
- Lean Meats
- Fish and Seafood
- Eggs
- Dairy
Plant-Based Sources
- Legumes
- Soy Products
- Nuts and Seeds
- Whole Grains
Comparison of Protein Needs for a 150-Pound Individual
| Activity Level | Grams of Protein per kg | Total Daily Grams (for 150 lbs/68 kg) | Primary Goal |
|---|---|---|---|
| Sedentary Adult | 0.8 g/kg | ~54 grams | Prevent deficiency, support basic functions |
| Moderately Active | 1.2-1.7 g/kg | 82-116 grams | Maintain muscle, support regular exercise |
| Intense Training/Athlete | 1.6-2.2 g/kg | 109-150 grams | Muscle building, maximum recovery |
| Weight Loss | 1.6-2.2 g/kg | 109-150 grams | Preserve lean muscle, increase satiety |
Potential Risks of Overconsumption
Excessive protein can strain kidneys and may lead to digestive issues and dehydration if fiber and fluid intake are insufficient. Excess is stored as energy or fat.
Final Recommendations
For a 150-pound person, protein needs range from 54 grams (sedentary) to 109–150 grams (active, weight loss, muscle gain). Prioritize diverse, high-quality sources throughout the day.

Conclusion
Daily protein intake for a 150-pound person varies based on activity and goals, from a minimum of 54 grams to over 100 grams for active individuals or those with specific health objectives. Tailoring consumption with varied, quality sources supports overall wellness.
