🧮 How Much Protein Do I Really Need Per Day? (Based on Activity Level)
Your protein needs depend on your age, weight, lifestyle, and fitness goals. Here’s a quick breakdown:
| Lifestyle | Protein Needed (grams/kg of body weight) |
|---|---|
| Sedentary (no regular workouts) | 0.8 – 1.0 g/kg |
| Active (light to moderate exercise) | 1.2 – 1.4 g/kg |
| Muscle building or heavy training | 1.6 – 2.2 g/kg |
| Fat loss or high protein diet | 2.0 – 2.5 g/kg |
| Older adults (over 60) | 1.2 – 2.0 g/kg |
👉 Example:
If you weigh 70 kg (about 154 lbs) and do strength training, your daily protein intake should be: 70 kg × 1.8 g = 126 grams of protein per day.
🧭 How to Calculate Your Daily Protein Needs Easily
To know exactly how much protein you really need per day, follow these simple steps:
-
Find your body weight in kilograms.
(Divide your weight in pounds by 2.2)Example: 165 lbs ÷ 2.2 = 75 kg -
Multiply by your activity factor.
Example: 75 kg × 1.6 (for active person) = 120 grams/day -
Distribute it across meals.
Aim for 25–35 grams of protein per meal for optimal absorption.
