Episode description
- A ketogenic diet improves weight loss, insulin sensitivity, and blood sugar control initially, but these gains typically level off after six to 12 months of adherence
- Long-term keto can elevate low-density lipoprotein (LDL) cholesterol levels, particularly during rapid weight loss, raising cardiovascular concerns especially in healthy young adults following this diet
- Restricting carbohydrates eliminates healthy fruits, vegetables, and whole grains, leading to deficiencies in essential vitamins (B-complex, A, E, K) and minerals like magnesium and potassium
- Extended ketogenic diet use increases risks of kidney stones, reduced bone mineral density, thyroid dysfunction, and harmful gut microbiome changes linked to cancer risk
- The keto diet works better as a short-term therapeutic strategy for metabolic inflexibility and diabetes, but requires transitioning to balanced carbohydrate intake for long-term health
