A recent post by Dr Saurabh Sethi, a California based gastroenterologist trained at AIIMS, Harvard and Stanford, argues that leg strength is a stronger predictor of longevity than BMI or weight. He explains that lower body muscle supports glucose control, metabolic health, balance and even cognitive function, while weak legs raise risks of falls and chronic disease. He recommends simple strength exercises and daily movement to maintain independence and long term wellness.
