You bring up some more great points! I know a few people who are doing "their" version of Atkins, and it is recipie for disaster! My sis in law was doing Atkins, while smoking and drinking and having regular cheat days!!! And she gained 10 pounds!
Atkins clearly says not to yo yo with this diet, and not to cheat as one little chaet can set you back a week!
Also, a few I know are not excersising or taking nutritional suppliments and are not under the care of a doctor! Ug, bad news there!
All of these people I mention all blame the diet/life plan for their obvious failures! You hit the nail on the head, human nature......
