My wife and I did the
Advocare 24 Day Challenge about 8 weeks ago. It worked well for us and we have stayed on the nutritional supplements and kept to the diet and exercise guidelines. They are very easy to follow, and very sensible. After dropping about 10 lbs during the first 24 days, we are losing about 1 lb per week. I buy their products through my kids distributor account.
Not too hard to stick close to the diet when eating out, or partying with friends.
