Exactly. All diets fail and are pointless over the long term. This type of commentary will only serve to blame people for having diabetes, regardless of the genetic, biological, social, and psychological differences that led them to be an overweight diabetic in the first place. I am the poster child for these researchers. If you looked at me in year one, it all worked great. As time went on, hunger returned, irritability and cognitive effects of the low carb diet worked against me, my genetics and biology overwhelmed my initial success with no additional loss, and I was cooking for a family of four who didn't want to be eating low carb with me. It is completely useless science to look at the short term, compared to real life over several years. Diabetes is forever, diets are for a few months. All the years I spent dieting didn't cure my diabetes. DS did it within weeks. At $26,000, it was a health care bargain. They have no scientific support for their conclusion that low carb is better than WLS for diabetes after year 2 for most of the study subjects. I have 11 years without diabetes because of DS. I feel for the people they are putting through the pointless energy trying low carb eating and I hope these people find the only successful treatment for diabetes, which is WLS.
