When you look at physical activity from a fat-loss perspective, it’s all good news. A brisk, 10-minute walk each day will burn approximately 75 calories for the average person. In one year that’s over 27,000 calories or roughly eight pounds of body fat. Within ten short years, that’s a whopping 80 pounds of body fat. This kind of calorie-burning analysis adds meaning to that daily walk. Over time, your return on investment (7.5 calories burned for every minute walked) is spectacular. These numbers beat the best stocks Wall Street has to offer.
