Well Beyond 40 Calories Are Not The Problem, Your Hormones Are Storing Fat
Mar 2, 2026
The conversation explains why midlife fat gain is driven by hormonal shifts rather than calories alone. It covers how declining estrogen, progesterone and thyroid changes raise cortisol and insulin, promoting belly fat. Muscle loss and low protein intake worsen metabolism. Practical screening tips, sleep and resistance-training priorities, and a cyclic calorie plan to protect thyroid function are highlighted.

Episode notes
Low Estrogen Triggers Higher Cortisol And Insulin
- Declining estrogen raises cortisol and insulin, which promotes belly fat and inflammation.
- JJ links low estrogen to higher insulin (locking fat cells) and chronic cortisol to increased hunger and visceral fat storage.
Too Much Cardio Can Reduce Overall Daily Movement
- Excessive cardio can reduce daily non-exercise movement (NEAT), cancelling metabolic benefits.
- JJ cites literature showing people compensate for exercise by moving less the rest of the day.
Use Simple Measurements To Screen Visceral Fat
- Check waist-to-hip and waist-to-height ratios to screen for visceral fat risk.
- JJ says waist/hip >0.8 or waist > half your height indicates higher visceral adipose tissue and metabolic risk.
