Why Diet Alone Isn't Enough
Many people believe eating less automatically leads to better health. While nutrition is incredibly important, health depends on several interconnected factors including:
- Physical activity
- Sleep quality
- Hydration

Someone who eats perfectly but never exercises, sleeps poorly, and experiences constant stress is unlikely to enjoy optimal health.
The healthiest people develop balanced lifestyles rather than restrictive diets.

Consistency always beats perfection.
