Protein targets for a 200 lb man, by goal
At 200 lb (91kg), your daily protein need depends on what you're asking your body to do. Here's the full ladder, computed for your weight:
| Goal | Protein per day at 200 lb |
|---|---|
| General health (0.8–1.2 g/kg) | 73–109 g |
| Active / fitness (1.2–1.6 g/kg) | 109–145 g |
| Losing fat (1.6–2.0 g/kg) | 145–181 g |
| Building muscle (1.6–2.2 g/kg) | 145–200 g |
| Athlete (1.8–2.4 g/kg) | 163–218 g |
Most men at this weight land around 145 g/day — the active midpoint — and move toward the top of the ladder while cutting fat or lifting seriously.
What 145 g looks like across a day
- Breakfast (41 g): eggs + Greek yogurt
- Lunch (44 g): chicken breast + salad
- Snack (20 g): cottage cheese or a shake
- Dinner (41 g): salmon or lean beef + veg
The rhythm matters as much as the total: roughly 36 g per meal keeps muscle protein synthesis topped up through the day, instead of cramming everything into dinner. On keto, lean proteins get a 200 lb man to 145 g without denting the net-carb budget.
How 200 lb compares to nearby weights
Protein scales with body weight, so small weight changes move the target less than people expect: at 190 lb the active-to-cutting range is 103–172 g; at 220 lb the active-to-cutting range is 120–200 g; at your 200 lb it's 109–181 g. If your weight changes by 10–15 lb, recalculate — your target shifts by roughly 7 g per 10 lb.
Who should be careful
These figures assume a generally healthy adult. Kidney or liver disease, diabetes complications, or pregnancy call for an individualized target from a doctor or registered dietitian.
Methodology & sources
Targets come from your body weight in kilograms multiplied by an evidence-based grams-per-kilogram range for your goal — not a single one-size figure. General health uses the DRI/RDA floor of ~0.8 g/kg; active, fat-loss, and muscle-building ranges follow the International Society of Sports Nutrition (ISSN) position stand of roughly 1.4–2.2 g/kg for people who exercise, with the upper end for a calorie deficit or hard training. Adults 50+ get a small upward adjustment for age-related muscle loss (sarcopenia).
Sources: U.S. Dietary Reference Intakes (protein RDA), the ISSN Position Stand on protein and exercise, and USDA FoodData Central for the protein content of foods.

Frequently asked questions
- How much protein does a 200 lb man need per day?
- A 200 lb man needs roughly 109–181 g of protein per day. Around 109 g suits general activity, while 145–181 g is better for losing fat, building muscle, or training hard. That's about 36 g per meal across four meals.
- Is 145 g of protein a day enough for a 200 lb man?
- Yes — about 145 g sits in the middle of the recommended range for a 200 lb man and covers active lifestyles well. Push toward 181 g if you're in a calorie deficit or building muscle, since protein needs rise then.
- How was this number calculated?
- It multiplies body weight in kilograms (200 lb ÷ 2.205 = 91 kg) by an evidence-based grams-per-kg range — 1.2 g/kg for active up to 2.0 g/kg for fat loss and muscle building. Adjust for your exact goal and activity with the calculator above.
- Does this change on keto or low-carb?
- Your protein target is about the same on keto, but hitting it matters more in a low-carb deficit because protein protects muscle. Choose lean proteins to reach your grams without spending your fat or carb budget.
