Many people believe that weight loss is simply about walking more and not overeating, but Dr. Kunal Sood, an anaesthesiologist and interventional pain medicine physician, clarifies that the real driver of fat loss is maintaining a calorie deficit. This means consistently burning more calories than consumed over time. In a recent Instagram video, he explains that while walking can subtly increase daily calorie expenditure, it won't lead to fat loss if calorie intake exceeds calories burned. Dr. Sood suggests that effective weight loss comes from a combination of regular walking, a diet rich in protein, and minimizing unnecessary calories. He notes that those who achieve lasting results typically follow a few simple habits consistently, rather than relying on extreme workouts. This straightforward approach can help individuals achieve sustainable weight loss without the complexities often associated with dieting.
