I am trying to now. I am going to starve myself for a few weeks ;o
But are you really overweight? Or you just lack confidence?
My advice to you: sports. You are a young man, so sports is the best way to control your ideal weight after you reached it. No starving yourself though.
That won't work, trust me, you won't be able to do it for very long, and then you'll just eat enough to compensate all that you didn't eat before.
Eat healthy, cut down on carbs and fats and move (sports).
