- Weight Management:
- BMJ meta-analysis (2021): Low-carb and high-protein diets resulted in 10% greater weight loss over six months.
- Longevity:
- Cell journal (2022): A 20% reduction in calorie intake extended the lifespan of test animals by 15–20%.
3. Downsides of Healthy Eating
- High cost: Organic foods are 30-50% more expensive.
- Mental stress: Obsessive calorie counting may cause orthorexia.
