Re: to I have to have a strict diet too?
You don't necessarily have to cut anyhting out completely (although obvious junk is a good place to start). Often portion control will make a huge difference. But for starters, what are your current stats (height/weight) and what does your current diet look like; be a exact as you can with what foods, how much, and when you eat.
