Stress, cortisol and weight: how stress makes you gain fat (and how to stop it)

You eat well, train, sleep enough... but do not lose weight. Or worse, you gain it. The silent culprit could be chronic stress. And no, it is not pseudoscience: it is basic endocrinology.

What cortisol does to your body

• Increases appetite (especially for high sugar and fat food)
• Accumulates visceral fat (around organs, in the abdomen)
• Water retention (you feel bloated)
• Muscle breakdown (lose muscle, lower metabolism)
• Insulin resistance (higher risk of type 2 diabetes)

7 science-backed strategies

• 1. Walk 30 min daily outdoors (reduces cortisol 15%)
• 2. Meditate 10 minutes (reduces cortisol 25% in 8 weeks)
• 3. Sleep 7-9 hours (one bad night raises cortisol 37%)
• 4. Reduce caffeine after 2pm (caffeine elevates cortisol)
• 5. Strength train, avoid excessive cardio (too much HIIT raises cortisol)
• 6. Socialize: human connection lowers cortisol
• 7. 4-7-8 breathing: inhale 4s, hold 7s, exhale 8s
