Protein Intake for 200 lb, active Activity Level
Recommended daily protein gram target at this weight and activity level. Use the calculator below to try your own profile.
Recommended Daily Protein
145 g
Example
At 90.7 kg body weight and a "Active / Strength Training" activity level (1.6 g/kg), the recommended daily protein intake is about 145g (580 calories) — within the broader 73g-181g range used across activity levels.

What Is Protein and Why Do You Need It?
Protein is one of the three macronutrients, made up of amino acids that serve as the building blocks of body tissue — muscle, skin, enzymes, and hormones are all built from protein. Unlike carbohydrates and fat, the body doesn't store extra protein for later use, so a steady daily intake matters for repairing tissue, supporting immune function, and maintaining muscle mass.
The amount of protein a person should consume is not an exact science — the RDA baseline of 0.8 g/kg of body weight covers basic nutritional needs for a sedentary adult, while active individuals and athletes often benefit from 1.6-2.0 g/kg to support muscle repair and growth.
Protein Needs by Activity Level
Your daily protein target at 90.7 kg body weight across each activity level.
How Is Protein Intake Calculated?
This calculator applies a grams-per-kilogram-of-body-weight multiplier based on your activity level, ranging from the 0.8 g/kg RDA baseline for sedentary adults up to 2.0 g/kg for very active individuals and athletes doing intense daily training.
Why Athletes Need More Protein
Resistance training and endurance exercise both increase muscle protein breakdown and the demand for repair and adaptation. Studies on strength athletes generally support intakes in the 1.6-2.2 g/kg range to maximize muscle protein synthesis, well above the sedentary RDA.
Protein Timing and Distribution
Spreading protein intake across 3-4 meals a day, with roughly 20-40g per meal, tends to support muscle protein synthesis more effectively than consuming the same total in one or two large meals, since the body can only use so much protein for muscle building at once.
Is More Protein Always Better?
Beyond a certain point — generally around 2.0-2.2 g/kg for even the most active individuals — additional protein provides diminishing returns for muscle building and is simply used for energy or excreted, so there's little benefit to intakes far above the ranges shown here.
Example — Your Current Inputs
At 90.7 kg body weight and a "Active / Strength Training" activity level (1.6 g/kg), the recommended daily protein intake is about 145g (580 calories) — within the broader 73g-181g range used across activity levels.
Additional Example — A 70 kg Sedentary Adult
A 70 kg (154 lb) sedentary adult following the RDA baseline of 0.8 g/kg needs about 56g of protein a day — roughly two palm-sized servings of meat, fish, or an equivalent plant-based combination, spread across meals.
About These Parameters
- Body Weight
- Protein needs scale directly with body weight, since more body mass means more tissue to maintain and, for active people, more muscle to repair after training.
- Activity Level
- Determines your grams-per-kilogram multiplier — sedentary adults need the least, while athletes doing intense daily training need close to the top of the range to support recovery and muscle growth.
Frequently Asked Questions
How much protein do I need to build muscle?
Most research on resistance training supports 1.6-2.2 g/kg of body weight per day for maximizing muscle protein synthesis, combined with a consistent strength-training program and adequate total calorie intake.
Can too much protein be harmful?
For most healthy adults, higher protein intakes within these ranges are not harmful, though people with existing kidney disease should consult a doctor before significantly increasing protein intake.
Does this apply to plant-based diets?
Yes, the gram targets are the same regardless of protein source, though plant-based eaters may need to combine multiple protein sources (like grains and legumes) across the day to get a complete amino acid profile.
