Losing weight is really hard for some people. This is because dieting isn't fun. And keeping the weight off is even harder. You have to make lifestyle changes that go against your natural tendencies to eat what you want, even if it's bad for your body. You also have to exercise, and while some people do enjoy it, for most it's just grueling work.
But if you want to lose weight, you have to do these things, there's no way around it. The best way to lose weight is to incorporate a healthy diet, with moderate exercise, that is approved by your doctor.
But this takes a long time. If you want to lose weight fast, you have to put out more effort, and eat a diet that may or may not be healthy for you. The fasted way I know of to lose weight is a high-protein, low carb diet, coupled with muscle building exercise.
There is much debate whether the Atkin's diet, or other similar low-carbohydrate diets are harmful or not. With the amount of conflicting information out there, it's impossible to tell. Either way, you should always consult your doctor before started any type of diet or exercise program.
But beyond the debate of whether the low-carb diet is harmful or not, I know it actually works. You can lose quite a bit of weight on it if done correctly. And add in building muscle for increased metabolism and fat-burning , you will lose weight faster, and the weight you lose will be fat.
First, you need to go out and buy one of the low-carb diet books, like the Atkin's Diet Revolution, and read it from cover to cover. There is a lot of information to absorb, about how fat is burned, and different medical tests you'll be encouraged to take, and supplements you may need during the diet.
Most low-carb diets have an induction phase, where you will reduce your carbohydrates down to almost nothing, between 15 and 30 grams per day. This causes you to reach ketosis, which is what makes you start burning fat fast. This phase shouldn't last more than about two weeks. After that, you slowly increase carbohydrate intake, until you reach a point where you've reached your weight loss goals, and you know how many daily carbs you can have and still maintain the weight you desire.
Make sure you take any suggested supplements, as you won't be getting all of the nutrients your body needs. Also make sure you're getting plenty of fiber to regulate your system, and at least eight 8oz. glasses of water every day.
Include a muscle-building workout with your low-carb diet, and you will increase your fat-burning capabilities, as muscle burns more fat. Adding muscle also increases metabolism, which causes your body to burn fat quicker as well.
