Saw this when it came out. And interestingly, it accords with the experience of a client I worked with a little over a year ago. She was a very heavy, Type II diabetic who had survived a heart attack. Her doctor read her the riot act and basically ordered her to lose weight.
I received a letter from her doctor directing me to supervise a 1,200 calorie diet and to encourage increased activity. So, I helped my client to configure an eating plan that would have her operating within her calorie allowance and had her on a walking program. I also worked with a registered dietician whose chief recommendation was to have my client eating a half-cup of yogurt before bedtime.
Results: client lost in excess of 10% of her bodyweight in short order. Over a period of 6-8 weeks her daily blood sugar ratings dropped from 400-500 (kid you not) to between 80-120. Her A1C dropped from above 13 to below 10 during that time.
She and I discontinued our working relationship shortly thereafter, but I continued to check on her periodically, at which times she'd enthusiastically report that she was maintaining her weight-loss, within a few pounds, and was walking several miles a day.
Her doctor and dietician were ecstatic. And by every measure, my client was a stunning success story ... until she had another heart attack.
She's fine now. Oh, the study:
