       Weight Loss Programs: Slim Evidence and Thin Results
       By Larry Husten
       Edited by David G. Fairchild, MD, MPH
       Some weight loss programs may be slightly better than others,
       but in the long run none has been able to produce significant,
       sustained weight loss, concludes an Annals of Internal Medicine
       review. For even the best programs, an editorialist writes,
       "weight loss is modest and likely below patients' expectations."
       Researchers reviewed 45 U.S. trials evaluating 11 programs:
       Weight Watchers, Jenny Craig, Nutrisystem, Health Management
       Resources (HMR), Medifast, OPTIFAST, Atkins, The Biggest Loser
       Club, eDiets, Lose It!, and SlimFast. These programs were
       compared with controls, which generally provided traditional
       counseling and education.
       At 1 year, only Jenny Craig and Weight Watchers were able to
       show even modest weight loss compared with controls: 4.9%
       greater weight loss with Jenny Craig, 2.6% greater with Weight
       Watchers. Nutrisystem and very low calorie programs (HMR,
       Medifast, OPTIFAST) resulted in short-term (3–6 months) — but
       not longer-term — weight loss.
       The editorialist writes that the study "highlights something
       that researchers ... have known for decades: Structure and
       intensity of contact are highly correlated with program success.
       It is unsurprising that highly structured programs with
       in-person social support, such as Weight Watchers and Jenny
       Craig, seem more effective in the long term than less structured
       interventions."
