How to cope with the hunger? I attempted to enjoy it. I thought of the movie Lawrence of Arabia, in which T.E. Lawrence says, 'The trick is not minding that it hurts.' I told myself that the mild ache was only the sensation of evaporating fat. That interpretation has some basis in physics. When you lose weight, most of your fat is converted to the gases carbon dioxide and water vapor, and so you get rid of fat by breathing it out of your body.
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.
But you’ll likely experience some benefit before then. Fiber helps slow down your digestion and requires more chewing, which helps signal to your body that it’s full, keeping your hunger in check throughout the day. One small study published in Food & Nutrition Research actually found that men who ate meals rich in high-fiber foods, like beans and peas, felt more satisfied than those who focused only on protein-rich foods, like pork and veal. Adult women should aim to eat 25 to 28 grams of fiber per day.
