Ketogenic Diet Boosts Short-Term Weight Loss, Long-Term Risks Unclear
The Ketogenic Diet in Obesity Management: Friend or Foe? "KD exerts anti-obesity effects through multiple pathways, including induction of nutritional ketosis, appetite suppression, enhanced fat oxidation, and improved insulin sensitivity. Clinical trials report significant short-term weight reduction and enhancements in glycemic control and lipid profiles. However, concerns persist regarding long-term adherence, cardiovascular risks, increased workload placed for the kidneys (renal strain), micronutrient deficiencies, and alterations in gut microbiota. Long-term benefits are debated, with evidence being limited and heterogeneous." https://t.co/xumeniENTb
