Evidence-based guidance for athletes navigating training, fueling, recovery, body composition, and performance while using GLP-1 medications.
Power, pacing, and fuel on the bike.
Gut-friendly fueling from easy miles to race day.
Carbs, electrolytes, and hydration timing.
Keep lean mass while the scale drops.
Sleep, repair, and returning to form.
How these medications affect training.
Appetite changed. The ride didn't. How cyclists on GLP-1 medications can think about carbs, hydration, protein and recovery when hunger is no longer a reliable guide.
How much protein you need on semaglutide, tirzepatide, or other GLP-1s. Why the standard target falls short and how to hit it when appetite is gone.
GLP-1s can blunt thirst, slow gastric emptying, and change sodium handling. What to drink, when, and how much.
It is not the drug. It is glycogen. Here's how appetite suppression drains your tank mid-workout and how to fix it.
Gut-friendly fueling for runners on semaglutide or tirzepatide. Easy miles, long runs, speed work, and race-day strategy.
Keep muscle while losing weight on semaglutide or tirzepatide. Protein, peri-workout carbs, and recovery for lifters.
Fueling for rowing and erg sessions on semaglutide or tirzepatide. High-intensity, high-sweat, repeat-effort nutrition.
Protein has a job. Carbohydrate has a job. Fat matters too — but for athletes, its target makes more sense when you look at the whole energy picture.
Carbohydrate is the primary fuel for harder training. When a GLP-1 makes eating less automatic, athletes need to make fueling more intentional.
Your appetite changed. Your training needs didn't. Four things athletes should protect on GLP-1 medications: fuel, muscle, hydration, and recovery.
You finished the workout. Your body isn't finished. Refueling, muscle, fluid, and rest when appetite no longer drives the recovery decision.
