couple of tips from me,
1. Buy a shirt that is 2 sizes to small. hang that bitch some where you will see it everyday, do not stop until you fit this shirt.
2. Chew gum while cooking big meals, this will stop you from "snacking".
3. Keep a log, and a food journal if you want to get crazy like i do use
www.fitday.com (free service) will allow you track your calories, general rule of thumb is 16 X your bodyweight for losing fat (calories per day) break this into 5-6 meals and botta bing botta boom
4. Don't run/jog whatever but set a landmark and see how quick you can get there everyday, once you're getting there too soon make the land mark further.. etc..etc...
anyways I've done a crap load of research, and still losing weight my self up to 108lbs total lost thus far.. about 20lbs away from my goal, so I'm not talking out of my ass ;)
good luck
