A lot of people won't do the work. It's a lot easier to take drugs or even follow an oversimplified diet to lose weight. I remember reading one of the Aumbass Principles threads a few years back and it was essentially a modified Atkins. It's probably different now but I'm not very fat and probably wouldn't use something like that to lose weight.
The only show I did I used a carb cycling diet. Which really caps the lows of Atkins, because you only go into Ketosis for about a day and a half a week..
Found I lost weight too fast with it and came in way too light.
Now I just follow a few simple rules to maintain.
No Sugary Drinks and no fries.
Too many empty calories and really play around with insulin levels.
If I was to do another show, which I won't, I would follow a similar carb cycling plan, however I would really watch my fat intake. Most likely using some type of fish oil supplement.
