If you’ve ever felt like your workouts leave you hungrier than ever or that sugar cravings hit harder after exercising, it might not just be about willpower—it could be your genes.
New research says the FTO gene may be driving those cravings as it alters muscle metabolism and makes muscles less efficient over time while ramping up hunger signals. But by making small changes to what and how you eat after workouts, you can take control and stop your genes from sabotaging your progress.
What Is the FTO Gene?
FTO is a nutrient-sensing gene that plays a major role in regulating hunger and energy use. Its highest expression is in the hypothalamus, which is important for appetite control and hormone regulation, and also in fat tissues (adipose cells) and muscles. Recent studies have shown that FTO can control eating behaviors as it responds to satiety signals in the central nervous system.
