Episode notes
Address B12 By Diet Or Diagnosis
- Supplement B12 if you follow a strict plant-based diet or eat no animal foods.
- If B12 is low, investigate causes like celiac disease or pernicious anemia before just supplementing.
Avoid Doubling Up Supplements
- Avoid taking many overlapping supplements to prevent toxic overdoses of A or D.
- If unsure, consult a registered dietitian before combining products.
Weight Loss Requires Holistic Change
- Very low-calorie diets can work but are hard to sustain and often reflect deeper causes of obesity.
- Weight loss success usually needs holistic changes beyond calories alone.
