Unfortunately, it's not as much as you would think. As soon as your body detects starvation it starts to shut down unnecessary activity, metabolism slows and you will start to rob muscle mass for necessary nutrients. As muscles start to diminish, you'll burn fewer calories and your weight loss program will not be as effective as you hoped. Instead, do maximize weight loss and to KEEP it off and do it in a healthy way, try feeding yourself properly and exercise to burn calories. Remove fat intake from your diet. You can loose weight safely for a couple weeks without ANY fat calories. Recognize that fats are very high density calories. One gram of fat is 9 calories, so cutting out fat helps a lot. Fats hide in all kinds of sneaky places. Cheese is bad for your diet, as is fried food and butter. Instead, eat a low calorie diet, with plenty of fish and other proteins. Red meats (beef, pork, lamb and any other mammal meat) should be trimmed of fat before you GRILL it (don't fry ANYTHING), and chicken should have the skin removed and fat trimmed. Avoid hamburger, since most butcher shops put a LOT of fat in the hamburger as they grind it. Eat some fruit regularly, but avoid avocado and anything else with oils. While potatos aren't a source of fat or calories, they are almost impossible (at least for me) to eat without butter, sour cream or SOMETHING made with a lot of fat. For a couple weeks, count every fat gram and weigh everything you eat. Eat smart and limit your fat grams to less than 20 grams per day, and save them for fish, fowl and trimmed red meat. Read labels and don't eat anything with sugar in the first 3 ingredients. Write down everything you eat and eat plenty of raw fruits and veggies. After you've done all of that, you're half way there. You also need to exercise, a lot. But that diet will help you since you'll have the protein to keep your muscles healthy. The exercise will cause you to burn far more calories and you'll LOOK good when you're done. Remember that it took a long time for you to put those calories on, and any attempt to take them off too quickly could turn out to be unhealthy.
