There are two critical aspects of weight management – weight loss and prevention of weight gain (or weight regain). The key to weight loss is diet – eating less by controlling portion sizes and making appropriate food and beverage choices. The key to preventing weight gain (or regain) is exercise. For that purpose, some studies suggest that for adults, walking 10,000 steps a day is about the right amount—and it takes more than 30 minutes of exercise to reach that goal. To get started, wear a pedometer each day for two weeks and don’t do anything to change your normal routine. Then, take the highest amount of steps you’ve walked and add increments of 500 steps every two weeks until you reach the goal.
