Weight loss isn’t just about calories in versus calories out—hormones play a major role in how your body stores fat, regulates appetite, and burns energy.
1. Insulin
Insulin helps manage blood sugar but also promotes fat storage. High insulin levels—often caused by frequent snacking or sugary foods—can make weight loss harder.
2. Leptin & Ghrelin
Leptin signals fullness, while ghrelin stimulates hunger. Poor sleep and chronic stress can disrupt their balance, increasing cravings and overeating.
3. Cortisol
Cortisol, the stress hormone, can trigger fat storage—especially in the belly—when elevated for long periods.
4. Thyroid Hormones
These regulate metabolism. An underactive thyroid slows calorie burn, making it tougher to lose weight despite diet and exercise.
Understanding how hormones affect your body can help you make smarter, more personalized decisions for lasting weight loss and better health.
