I recommend Perry Weight Loss and Nutrition Clinic in Hoffman Estates, IL to anyone who is serious about weight loss. They got great diet programs, Optifast is a full meal replacement program and IdealProtein is best if you have trouble with metabolism and having difficulty to lose weight.I have lost 19 lbs so far on the IdealProtein and this is my 5th week. I look fabulous and feel great in my new clothes as this diet helps to lose fat from the hard to get places.Try them...you won't regret.My Best,Kristen
