IMHO. Some people don't do well on Atkins as some don't do well on CAD or the Zone. This is not a one size fits all diet world. There are many possible diets and many individual body chemistries. Each person needs to find the eating plan that meshes with his/her body chemistry and helps them lose and maintain a healthy body and body weight.

There is a thread on here called the Adam & Eve diet that might be helpful. It explains that different types of people do well on different types of diets, something I've always believed.

Reading the diets and research and seeing if the people who have succeeded on a plan fit your particular profile is helpful too. No one plan works for everyone. You just need to discover the plan that fits you.
