I don't do the whole iifym but I eat fairly low carb, 8oz of protein each meal or atleast I try to, protein bars/shakes as snacks. I eat fairly clean on weekends I may have a little cheat or have some drinks but besides that I'm pretty good with the eating. I also dont gain the weight all over its just str8 to the stomach/love handles, even when I drop weight, the place it never goes completely away is the stomach lol.....
