How Much Protein Do You Need to Lose Weight?
Protein is crucial for weight loss as it helps preserve muscle mass, increases satiety, and supports metabolism. Research recommends 1.2–2.0 grams of protein per kg of body weight daily for weight loss, depending on activity level and muscle retention goals. For example, a 70 kg person aiming to preserve muscle may need 84–140 grams of protein daily.
Factors affecting protein needs include:
- Activity level: Higher activity increases protein needs to support muscle repair.
- Calorie deficit: Larger deficits require more protein to prevent muscle loss.
- Body composition: Leaner individuals may need higher protein per kg.
Use our high-protein, low-calorie diet guide to plan meals that align with your protein needs.
Tip: Combine high protein intake with a calorie deficit using our macro calculator for optimal fat loss.
