Lose 20 pounds

There are a lot of diets you can choose to try, such as the low carb weight loss one, but if you stop and think for one second, you'll realize that losing 20 pounds is really a math problem: we eat food to get calories, in order to supply our body with energy for our vital functions and for our duties and pleasures. If we give the body more calories than it needs for all these activities, the body would store those calories as fat, and this is why we need to buy bigger clothes every once in a while.
If we give the body less energy (less calories) than needed, our body is smart and it will burn some fat deposits to solve this problem and get the extra energy. Consequence? We lose weight. This is pure math, the rest is only weight loss myths. We definitely should aim for a healthy weight loss, therefore we need to be careful what plans we choose to follow.

So, give your body less calories and it will burn the fats in the adipose tissue. Can you do that? Can you stop eating all that chocolate and all that ice cream? Can you drink your tea without sugar in it?

I think you can, but you need a strong motivation, so ask yourself twice if you really want to lose those 20 pounds or not. If you are not convinced, it is better not to try at all. If you want to give it a try, note that some printable weight loss charts can help you trace your progress and stay motivated.
