Episode notes
Prioritize Calories, Quality, Then Timing
- Nutrition has three ranked priorities: calories first, food quality second, and timing last.
- Regularity and context (goals, health status, ancestry) must shape any diet choice.
Match Calories To Body Composition Goals
- Keep energy intake aligned with target body composition to avoid excess adiposity.
- Adjust calories or activity if you gain or lose undesired weight.
Early Eating Helps Certain Metabolic Profiles
- Early time-restricted eating can benefit sedentary or metabolically compromised people by improving blood pressure and insulin sensitivity.
- Benefits are modest and interact with activity timing and calorie distribution across meals.
