Artificial Intelligence is transforming the future of medicine. In this video, we explore how AI is discovering new drugs faster, cheaper, and more accurately than traditional methods.

Are you losing weight — but damaging your health? This research-backed explainer shows the hidden risks of rapid or extreme dieting and gives evidence-based steps to lose fat safely while protecting muscle and health. Losing excess weight can improve blood sugar, blood pressure and mobility — but the way you lose matters. Rapid, repeated, or poorly planned weight loss can cause metabolic slow-down, muscle loss, gallstones, electrolyte problems and increased risk of disordered eating. This video explains the science behind those risks and offers 6 evidence-based steps to preserve your health while you lose weight. Sources / further reading: Guidance and reviews from PubMed / NCBI reviews on adaptive thermogenesis, weight cycling, muscle preservation during weight loss, gallstones linked to rapid loss, and refeeding syndrome; clinical guidance from National Heart, Lung, and Blood Institute (NHLBI), StatPearls, Harvard Health, and reputable clinical resources. #Dieting #WeightLoss #Health
