Flaws in the study:

1. Participants knew their food was being monitored by the studiers. (not a real-world condition). This may have discouraged them from overeating.

2. Participants had no menu selections - all food was prepared for them. (not a real-world condition).

3. Participants were already diabetic or pre-diabetic, so they were under additional pressure to lose weight.

4. Did participants have real-world access to junk food, or was it restricted artificially?

5. "Researchers say people at risk of diabetes need a diet they can stick with." Just so.

6. No comparison to an Atkins alternative.

7. No long-term follow-up (yet).
