But everything can be changed. The simplest ways are your best friend here - do not believe in drastic diets, or magic pills / gadets. It's a simple math - if you burn more calories than receive, you lose fat. For this to happen, you have to increase your body metabolism, as the burning process happens exclusively there and then! And how do you do it?
Find a relaxing place to be, where you can exercise. Yes, you heard me, you will exercise. Because your body burns calories, when it repairs "broken" muscles - for that to happen, you have to lift weights. Not very heavy ones, but cardio doesn't help as you think.
When your body repairs muscle tissue, it burns calories. When you receive less calories than burn, you burn fat. Easy as that! Of course, don't eat things as margarines, white pastry and fried food - you'd destroy everything you've worked for so far!
