It takes time and dedication. You don't need pills just a good diet and exercise. First of all you don't need to starve. If you follow a proteinic diet you will lose weight, above all you will lose fat and conserve muscle. So you should it less carbohydrates such as white bread, white rice, spaghetti and consume more fruits and vegetables. I recommend you also to eat 5 times a day by little than not to eat nothing. You should consume protein such as : eggs( especially the white of the egg) , milk with very low fat, yoghurt with low percentage of fat, bananas, chicken especially chicken breasts. You should eat 0,8 g /kg protein per day. So you should consume more proteins, fruits and vegetables and less , very few carbohydrates. If you have any other question , you are welcome.
