For Athletes

Lose the fat. Keep the edge.

You train hard. You compete. GLP-1 medications can help you cut — but only if you protect the muscle and performance you've built. This is the playbook for doing it right.

The performance risks no one's addressing.

Performance Decline

GLP-1-driven caloric deficits can tank your training output. Without strategic nutrition timing, you'll lose strength, speed, and endurance.

Recovery Impairment

Reduced protein synthesis and appetite suppression mean slower recovery between sessions. Your body can't rebuild what it doesn't have fuel for.

Lean Mass Cannibalization

Your body doesn't distinguish between athlete muscle and sedentary muscle. In a deep deficit, it will burn both for energy.

Body Comp vs. Scale Weight

Athletes know the scale is meaningless. But GLP-1 dosing protocols were designed for metabolic patients, not performance-focused individuals.
