Episode notes
Ultra-Processed Foods Drive Obesity
- Ultra-processed foods (UPFs) are high in energy density, hyper-palatable, low in satiety, and cheap, driving increased calorie intake.
- These factors, combined, contribute significantly to the obesity crisis, especially in low-income areas.
Limit Access to UPFs
- Consider accessibility and convenience as major drivers of ultra-processed food consumption.
- Reducing ultra-processed food availability through effort and cost barriers may help lower overconsumption.
Protein Synthesis Boosts Energy Burn
- High protein diets increase muscle protein synthesis, which is an energy-expensive process that raises daily calorie expenditure.
- This increase in protein turnover may explain high protein diets' benefits for fat loss beyond digestion's thermic effect.
