How Much Protein for 90 kg?
See the daily protein in grams for a 90 kg adult across 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.

Quick Answer
How Much Protein for 90 kg?
For a 90 kg adult who is moderately active, a maintenance intake is about 144 g of protein a day, within a range of 126–162 g. That comes straight from the arithmetic: 90 kg × 1.4–1.8 g/kg = 126–162 g, with a midpoint around 144 g. The calculator above loads this maintenance baseline — change the goal to see fat loss (about 207 g) or muscle gain (about 189 g) instead.
What 90 kg Needs by Goal
The single biggest factor in how much protein a 90 kg person needs is the goal. The table below shows the daily grams at a moderately active level — the recommended figure is the midpoint of each band, and the range gives you room to sit higher when training hard or lower when activity is light.
| Goal | Protein (g/kg) | Recommended | Range |
|---|---|---|---|
| Maintain | 1.4–1.8 g/kg | 144 g | 126–162 g |
| Fat loss | 2.0–2.6 g/kg | 207 g | 180–234 g |
| Muscle gain | 1.8–2.4 g/kg | 189 g | 162–216 g |
Why Protein Rises for Fat Loss
The 90 kg fat-loss figure of 207 g sits well above the 144 g maintenance figure, and that gap is deliberate arithmetic. A calorie deficit is the setting where a larger protein share is most often chosen: protein is the most filling macro gram for gram, which describes why it helps with hunger, and it is the macro most tied to holding on to lean mass while calories are low. The target also scales with how much you train — at moderately active a 90 kg person cutting lands near the 207 g midpoint, while a very active day nudges toward the top of the 180–234 g range and a rest-heavy week toward the bottom. That describes why the numbers move; it is not a prescription for you.
Put Your 90 kg Number to Work
This page takes 90 kg as a given and shows the protein for it. To go further, adjust your goal, activity or body fat % on the Protein Intake Calculator. Then set the calories that protein fits inside with the TDEE Calculator, and split the rest of the day between carbs and fat with the Macro Calculator. These figures are general estimates for healthy adults, not medical advice.
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).
