How Much Protein for 200 lbs?
See the daily protein in grams for a 200 lb adult — for fat loss, maintenance and muscle gain — worked out for you instantly.
Protein Intake Calculator
Required: protein needs and lean-mass differ by biological sex (male or female).
Range: 15–100 years.
Range: 30–300 kg
Enter your height in centimeters (e.g., 170 cm)
In a calorie deficit, higher protein (1.8–2.4 g/kg) protects muscle and keeps you full.
Moderate exercise most days of the week. More training nudges the target up.
Know your body fat %? Enter it for the more accurate lean-mass method (protein per kg of lean mass, not total weight). Leave it blank to use your body weight. Don't know it? Estimate it with the Body Fat % Calculator.

Quick Answer
How Much Protein for 200 lbs?
For a 200 lb adult at a moderately active level, a maintenance intake is about 145 g of protein a day, within a range of 127–163 g. That comes from treating 200 lb as about 91 kg (1 lb = 0.4536 kg) and applying the maintenance band of roughly 1.4–1.8 g per kg: 91 × 1.4 ≈ 127 g at the low end, 91 × 1.8 ≈ 163 g at the top, with the midpoint near 145 g. The calculator above loads that maintenance baseline — change the goal to see fat loss (about 209 g) or muscle gain (about 191 g) instead.
What 200 lbs Needs by Goal
The single biggest factor in how much protein a 200 lb person needs is the goal. Maintenance asks the least, fat loss the most, with muscle gain in between. The figures below are all at a moderately active level (training 3–5 times a week); the recommended number is the midpoint of each range.
| Goal | Recommended | Range |
|---|---|---|
| Maintain | 145 g | 127–163 g |
| Fat loss | 209 g | 181–236 g |
| Muscle gain | 191 g | 163–218 g |
Why Protein Rises for Fat Loss
Notice that the fat-loss number for 200 lb is higher than the maintenance one — 209 g against 145 g. That is because a larger protein share is the one most people pick when calories are low: protein is the most filling macro gram for gram, and it is the macro most tied to holding on to lean mass while dieting. That describes why the fat-loss band sits higher, not a personal recommendation. The number also scales with how much you train — a sedentary 200 lb person lands nearer the bottom of each range, a daily strength trainer nearer the top, which is why the calculator nudges the band up with activity. If you want to see how many calories your body burns, that sets the energy budget the protein sits inside. These are general estimates for healthy adults, not medical advice.
Put Your 200 lb Target to Work
Protein is the anchor of the plate, but it is only one of three macros. Once you have your gram target, the next step is the rest of the day's calories. Head to the full Protein Intake Calculator to add a body fat % for the sharper lean-mass method, then split the rest into carbs and fat so the whole day adds up. Lock protein in first; the other two macros fill the space that is left.
Calculations are powered by the ISSN Position Stand on Protein & Exercise (Jäger et al., 2017), the International Society of Sports Nutrition consensus on daily protein for active adults; the lean-mass band follows Helms et al. (2014) and Phillips & Van Loon (2011).
