• Keep a food log
  • Weigh yourself every day or so. Log it.
  • Cut out the dumb foods and substitute something good. Not that hard and I'm a junk food junkie.
  • Drink less alcohol. It'll make you feel better too. (No hangover this morning and I feel great). Plus, drinking less you'll make fewer bad food choices.
  • Don't go for too much in one goal. A pound a week is probably realistic or you'll put it right back on.

Good luck. I need to lose 20+ lbs myself. I used to be skinny. I'm not anymore.
