Query: Not a fad, not a gimmick but a lifetime program

I love the Atkins Diet. Lost over 48 lbs and totally restructed my figure. Lost in major fat areas like waist, hips and thighs while lowering cholesterol at the same time.This newest book by Atkins prooves that you can be a lifer on the program. Plenty of recipes and menues, even holiday menues.By contrast, a diet is something that you go on and off of. And that is the reason for the yo-yo effect. Not to mention that most diets don't work and leave you too hungry, tired and irritable to stay on.I am also glad to see that Atkins is finally getting recognized as a safe program by the medical community which opposed him for so long.How unfortunate that Dr. Atkins had to pass away just as his program is finally getting the recognition it deserves.Nevertheless, a great program by a great man. Dr. Atkins, thank you for developing this program and RIP.
