Use a calorie-needs calculator like LIVESTRONG.COM’s MyPlate app to figure out your daily calorie needs, then subtract calories to create your energy deficit. With an app like MyPlate, you can factor in your weight-loss goal, and it will tell you the exact number of calories (as well has how much fat, protein and carbohydrates) you need to reach that goal.
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
