I am on my last day of the 14 day detox from David Kirsch. It wasn't too bad. It's the ABCDEF's that you can't do...alcohol, bread,carbs (grains, pasta, bread etc)no dairy,extra sugar subs or sugar, or fruit. Plus you work out every day essentially....I was exhusted the first 5 days really dragging but then it changed. I was really happy about that...I have lost 9 lbs. That's pretty extreme. He suggests taking a rest week or two before trying it again. My skin is pretty clear and I don't think I cheated (hidden sugars etc...) I am pretty impressed by the results. I have another 14 lbs I'd love to shed permanently to be my dream weight but we'll see. I am pretty new at working this hard and have only been doing the intense workouts and clean diet for 1.5 years. It shows and I look amazing. Still I have a ways to go...turning 47 in a week I know I look really great fro a geezer. LOL Still I have a mission to have a smoking cover girl body by my 50th. I think honestly it takes at least a few years to reach that goal for my genetics and disipline.
You can go to David Kirsch.com and see his stuff. I am pretty sold on this plan. Honestly it's the Alcohol and second hand binging with the BF television late snacking...hell. This is what gets and keeps the lbs on. seeing my abs for the first time "ever " is motive enough for me to do this "fast" again in a week or two.
Good luck.
