Since Christmas day i have used Zantrex3 and have no luck. It says no special diet or exersize right? Well I am a 6\'5 325 very active 44 year old guy and I just don\'t get it! I look like I must tear the reffer door off the hinges in my sleep or something because I sure as hell don\'t eat like i look and not to mention working 14-16 hour days at my business and heavy chores around my house all weekend. The Zantrex don\'t work for me, I gave it a fair shot! SO SCREW IT I WILL STAY FAT AND BE HAPPY WITH IT! PS the only good I got from the stuff was the buzz to keep me working my whatever off! Good luck all and May God Bless your lives.
