Keto Diet Risks Are Varied, Multiple Studies Show

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
