Episode notes
Twin Weight Gain
- Chris van Tulleken's twin, Xand, gained significant weight after moving to the US and consuming a diet high in ultra-processed foods.
- This weight gain led to severe health complications, including a heart problem exacerbated by COVID-19.
Twin Studies and Health
- Identical twin studies highlight the impact of environment and lifestyle on health outcomes, as twins with identical genes can experience significant differences.
- This observation led Tim Spector to realize that factors beyond genetics play a crucial role in health.
UPF and Health Risks
- Ultra-processed food (UPF) is the primary cause of obesity at a population level.
- UPF can rewire the brain and makes up over half of the average person's calorie intake in the UK and US.
