Key takeaways
- Eating less makes it easy to fall short on protein.
- A 2025 joint advisory says 1.2 to 1.6 g per kg a day has been proposed during weight loss.
- This is an estimate, not a prescription.
How it is worked out
Your weight in kilograms, multiplied by 1.2 and by 1.6, rounded to the nearest gram. The same advisory warns that using your actual weight can overstate what you need, and that there is no agreed method. It also mentions a simpler target of 80 to 120 g a day, and says to avoid 2 g per kg or more for long periods.
