I am currently doing the FAT FLUSH PLAN by Ann Louise Gittleman. She is a real expert in nutrition. Even though I don't need to lose weight, this plan is excellent for overall detox of your system. She really stresses how important it is to keep your liver functioning well. I have been doing it for about three weeks now. I am noticing a big difference. It's definitely a lifestyle, though, and not a one-day fix.
