One 75-minute brisk walk a week cuts belly fat as well as three sessions, study finds

A four-month trial involving 315 adults with central obesity found that a single weekly session of 75 minutes of brisk interval walking reduced body fat, trimmed waistlines and improved cardiovascular fitness about as effectively as splitting the same exercise across three sessions per week. The findings suggest that even a minimal weekly exercise dose can deliver significant health benefits for people carrying excess abdominal fat.
