For the most part I have changed the way I eat.
Stopped some bad habits like, eating at Taco Bell, eating regularly at Buffalo Wild Wings, making my almost nightly run to Walmart to get a pint of ice cream.
Started some good ones: working out 5 days a week eating many more greens meals, going to bed earlier, drinking juice (that I have juiced).
I have lost a ton... 36 pounds, but in all honesty, I need to drop at least another 17 - 27 pounds. And I need to start lifting a bit too.
