How to Lose Weight Without Dieting At Home Permanent Weight Loss Tips Somya Luhadia<br /><br /><br />The best approach for weight loss is reducing the number of calories you eat while increasing the number of calories you burn through physical activity. To lose 1 pound, you need an expenditure of approximately 3,500 calories. You can achieve this either by cutting back on your food consumption, by increasing physical activity, or ideally, by doing both.<br /><br />For example, if you consume 500 extra calories per day for one week without changing your activity level, you will gain 1 pound in weight (seven days multiplied by 500 calories equals 3,500 calories, or the number of calories resulting in a 1-pound weight gain). Likewise, if you eat 500 fewer calories each day for a week or burn 500 calories per day through exercise for one week, you will lose 1 pound.
