Episode notes
Environment Drives Overeating
- We live in a toxic food environment where processed foods are engineered to overwhelm satiety and drive addictive eating.
- This environment plus stress and long shifts in healthcare makes weight gain very easy and hard to reverse.
Personal Weight Changes Shared
- Michael Mosley reversed his type 2 diabetes by losing around 10 kg and reducing liver and visceral fat.
- Jack Mosley also gained 15 kg as a junior doctor and later lost it with small sustainable changes.
Visceral Fat Is The Dangerous Type
- Visceral fat is metabolically active and raises risk for diabetes and cardiovascular disease.
- Subcutaneous fat is less harmful, so body composition matters more than appearance alone.
