Episode notes
Prioritize Protein for Special Groups
- Pregnant, breastfeeding, elderly postmenopausal women, babies, critically ill, and elite athletes need more protein.
- Increase protein intake from whole foods, emphasizing plant-based sources rather than supplements.
Protein Needs Vary by Activity
- Protein needs vary by age, growth stages, and physical activity levels.
- Serious athletes or bodybuilders may require up to double the average protein intake, but casual gym-goers do not.
No One Best Macronutrient Ratio
- Diets varying fat, carbohydrate, and protein ratios all work short term for weight loss.
- Long-term success depends on personal adherence and healthfulness of the diet, not just macronutrient ratios.
