I think Berardi has it dialed in. It's sort of a combination life coaching, nutrition coaching, workout program.
It's based on daily lessons and changing one habit at a time. You do a habit for two weeks, then two weeks later, you keep the old habit and start a new one. The lessons are mostly, but not always, based around the habits.
In the men's track, you can go one of three ways: fat loss, recomp (some weight loss with muscle gain), or full on building. The workouts are tailored to each approach, and sometimes the lessons are different. I went with the middle recomp program.
The nutrition stuff is all whole-foods based. Lots of lessons on choosing good foods, on food prep, etc.
Some of the coaches write occasionally for T-Nation, so you're likely to see a lot of cross-over.
