Yes mate, I lost 20kgs with it, but doing it for an extended time I think contributed to my issues with food, especially binging. If you have any other issues in your life you are dealing with, adding in structured starvation is the worst thing you can do imo.
I've read lots by lyle macdonald, and he is a genius, but I think this plan is not suitable for cat 3 dieters for the long term. If your cat3 you are overweight a lot, so their are background issues you haven't dealt with and adding this ontop is dangerous. All imo of course.
As I said in the previous post, it's more beneficial to run for a short time( 4 days max) followed by maintenance if you want to keep 1) metabolism firing 2) intensity in gym 3) sanity.
If you can keep it going do it just hit up those free meals.
How are you finding it?
