As previously mentioned, for workouts, check out Crossfit.com or for something almost as good, P90X (both are excellent).
For nutrition, eat real food, not processed junk. If it has a nutrition label and a wrapper on it, it probably isn't food (ironic). You want to feed your lean body mass and nothing else. Cut out the sugar (yes, all of it). Limit your carbs, especially grains (yes, all of 'em). (It feels like detox at first
) Get your carbs from fresh veggies and fruit.
I've lost 37 lbs since January this year mainly by changing what I ate and following the Primal Blueprint plan outlined at www.marksdailyapple.com
. I am 5'10" was 240 lbs at New Years, I am 203 today, and losing a steady ~2 lbs of fat per week. I just turned 40 and feel better now than I did at 30.
