How do you eat and get fat?

You don't. PEOPLE WHO LOSE WEIGHT TOO FAST DO DAMAGE TO THEIR BODIES. The best way to lose weight is to change the way you eat, and make it a lifetime commitment to yourself. See your doctor, and they will recommend an eating plan with exercise. (My doctor recommended the diabetic diet, and I lost 30 lbs in about 6 months.) You should lose 1-2 pounds per week, and then you can KEEP IT OFF!!

Now, if your doctor deems that you are morbidly obese, he/she can make healthy recommendations about how to save your life by losing the weight needed.

How fast is fast? Weight is determined by calories in versus calories spent. Fat is the bank account of the body. If you are losing fat, just use more energy and take in less. Losing muscle is a faster way to lose weight. It is easier, less healthy and results in a less desirable figure, usually. As for losing fat one of the best ways to use more calories in a day is to build more muscle. Muscle has a high caloric maintenance fee, but it is dense so even though you will get smaller building muscle and using up fat the scales won't show as dramatic a difference as the tape measure. I would recommend eating balanced regular meals, getting enough fiber of both sorts, getting some aerobic exercise in and some strength training. And sell your microwave. You will eat better and enjoy the food more.
