The RYM Approach to Protein
Most macro calculators overestimate protein or use arbitrary percentages. The RYM Approach is to base your protein target on lean body mass — the actual muscle, organs, and tissue that need fuel — not total body weight. Here's why:
Preserves muscle during fat loss — Protein protects your hard-earned muscle when you're in a calorie deficit.
Supports muscle growth — If you're building, you need adequate protein for recovery and growth.
Avoids excess — You don't need to eat your body weight in protein if 30% of that weight is fat. We calculate what your body actually uses.
This approach is backed by research and years of real-world results. It's precise, sustainable, and effective.

Why your protein is lower than other calculators
The RYM approach calculates protein from lean body mass — so you're fueling the tissue that actually needs it, not the fat. This is more precise, more sustainable, and backed by research.
