If you’ve been gaining weight despite eating well and training, the problem might not be your discipline — it could be your hormones.
Hormones run the show when it comes to how your body stores fat, builds muscle, and regulates appetite. When they’re out of balance, even the “perfect” plan won’t deliver the results you expect. Here are 5 places worth checking:
1. Thyroid Function (T3, T4, TSH)
Your thyroid is your metabolic thermostat. When it’s under active, metabolism slows, energy tanks, and fat loss feels impossible no matter how clean you eat. A simple blood test can reveal if this is part of the puzzle.
2. Cortisol Patterns
Cortisol isn’t just a stress hormone — it’s a fat storage hormone when it stays elevated. Chronically high cortisol from poor sleep, overtraining, or constant stress drives cravings, messes with blood sugar, and pushes fat to the midsection.
3. Insulin Sensitivity
Insulin is the key that lets nutrients into your cells. But when sensitivity drops, your body stores more food as fat instead of using it for energy. Early signs include fatigue after meals, constant hunger, and stubborn belly fat.
4. S*x Hormones (Testosterone, Estrogen, Progesterone)
These hormones influence where fat is stored and how much muscle you can build. Low testosterone can mean less muscle and slower metabolism. Estrogen or progesterone imbalance can drive water retention, cravings, and body composition shifts.
5. Leptin & Ghrelin
These are your hunger and fullness hormones. When they’re dysregulated, your body either never feels satisfied or doesn’t signal hunger properly. This explains why some people feel like they’re fighting their own appetite every day.
If one or more of these are off, no amount of cardio or “clean eating” is going to fix it. The real key is identifying which hormone system needs support and creating a plan around it.
If you had to guess, which of these 5 do you think is giving you the most trouble right now?
