Prepared meals and incentivized weight-loss program for obese and overweight women

Blog Entry, Health

In another article being released early online, Cheryl L. Rock, Ph.D., R.D., from Moores UCSD Cancer Center, La Jolla, Calif., and colleagues, conducted a randomized controlled trial of weight loss and weight maintenance in 442 overweight or obese women (BMI, 25 — 40), ages 18 to 69, over a two year period with follow-up between November 2007 and April 2010.

The women were randomized into three intervention groups: in-person, center-based (167 women) or telephone based (164 women) weekly one-to-one weight loss counseling, including free-of-charge prepackaged prepared foods (from Jenny Craig, Inc.) and increased physical activity for 30 minutes a day, five days a week. The participants were eventually transitioned to a meal plan that was not based mainly on the commercial program. The third group was the usual care group (111 women) who received two individualized weight loss counseling sessions with a dietetics professional and monthly contacts. All participants were provided a small monetary compensation ($25) for each completed clinic visit.

At 24 months, weight data were available for 407 of the 442 women (92.1 percent of the study sample). The average weight loss for the women participating in the center-based group was about 16 pounds or 7.9 percent of their initial weight, about 14 pounds or 6.8 percent for the telephone-based group, and about 4.5 pounds for the usual care control group. “By study end, more than half in either intervention group (62 percent of center-based [n=103] and 56 percent [n=91] of telephone-based participants) had a weight loss of at least 5 percent compared with 29 percent (n=32) of usual care participants,” the authors report.

“Findings from this study suggest that this incentivized structured weight loss program with free prepared meals can effectively promote weight loss compared with usual care group,” the authors comment. “Importantly, weight loss was largely maintained at two-year follow-up.” They note that even small percentage weight changes can result in a reduction of risk for cardiovascular disease and diabetes.

In conclusion the authors write: “For clinical practitioners, the evidence suggests that the structured program as applied in this study provides another route for their overweight and obese patients to achieve and maintain weight loss through behavioral changes for at least a two-year period.”

Editor’s Note: Dr. Rock reported serving on the advisory board for Jenny Craig from 2003 — 2004. The study was supported by Jenny Craig, Inc. (Carlsbad, Calif.), which provided program activities, materials, and prepackaged food to individuals assigned to the commercial weight loss program. Funding was provided through a clinical trial contract to the coordinating center (School of Medicine, University of California, San Diego), which subsequently disbursed funds to the collaborating clinical sites and the laboratories.

Editorial: Treatment Options for Obesity

In an accompanying editorial, Rena R. Wing, Ph.D., from the Warren Alpert Medical School, Brown University and Miriam Hospital, Providence, R.I., writes, “… the results of the trial reported by Rock et al probably represent a best-case scenario.”

“The findings of this trial by Rock et al raise the possibility that if structured commercial weight loss programs could be provided free of charge to participants, both retention and average weight loss outcomes might be far better than when participants must pay for these programs.”

“Currently, insurance companies will often cover the cost of bariatric surgery for obesity (estimated at $19,000 – $29,000 per patient from insurance reimbursement data) but do not cover the cost of commercial weight loss programs (such as that evaluated in this study, with estimated costs of approximately $1,600 for 12 weeks of the program and for food.) Providing commercial weight loss programs free to charge to participants might be a worthwhile health care investment.”

    Summer,

    I would even say a big percentage of weight loss WILL reduce the risk of cardiovascular diseases and diabetes.

    Tell me honestly: Who usually has problems with the above mentioned diseases? Mostly overweight and obese people do. When they lose weight they will also reduce their chances of getting the disease by living a healthy diet and exercise.

    I think there is one problem most of the people face when trying to lose weight. It’s the motivation to do it. It’s about getting outside of your comfort zone. Feel free to read some more about motivation for weight loss here:

    Structured meal plans may be good for people who lack the self motivation of trying to improve their health. Healthy diet is of course a major component to improve your weight, but you also need exercise.

    I encourage everyone to check out my review of the best weight loss programs available on the market:

    This is very encouraging news indeed. Now the difficulty will be getting the appropriate funding to implement the support program. We need a study to show that it’s cheaper to pay for structured meals that actually get results for the obese patients than to pay for all the ongoing chronic health care requirements the obese patients will need in the long run as their health deteriorates.

    Great post. I especially found it useful when you stated that a small percentage of weight loss reduces the risk of cardiovascular diseases and diabetes.

    It’s quite scary how many young people are going on silly crash diets these days just to lose weight. The best and most effective way to lose weight and keep it off is just good old fashioned healthy food and exercise.

    While drinking protein shakes is more convenient on a tight schedule…if you have the time to cook a meal…eating has other benefits besides refueling your body. When you have finished your work out…your body is more sensitive to insulin and eating triggers its release into your body. Insulin helps your muscles better refuel for your next exercise and also trigger protein synthesis.

    Dieters who write down everything they eat lose twice as much weight as those who don’t…research shows. Your food diary should include a list of the calories or carbohydrates or whatever you are counting. Liquid calories count…too. You can write your intake in a small notebook…on your computer or in the margins of a calendar or day planner. You also can list the calories you burn by exercising. To keep yourself honest…continue to do this even after you’ve lost weight.

    1. As is clear from the latest finding that Fruits, Veggies Help Ward Off Lung Cancer, I still think Fruits are instrumental to stem even a broader spectrum of cancers when vitamins and the other ingredients in them Are Mixed with Other Nutrition, if quite a few media cover it up in favor of livestock businesses, noticeably in the U.S.

    It might sound outlandish, but the Vital Vitamins Mixed with Other Nutrition seem able to initiate us into the world of Vitality, improving resistance to depression.

    Plus, as we are all aware , taking a bath day-to day is best for improving immunity to depression as our body is also taking a breath.
     
    2. We are living in an age of Automation , naturally so the excess diet is more likely to work against our wellness since the residues lingering in our body should act as a hot bed for all forms of germs, bacteria, virus and the likes.
     
    3. Parents might want to turn focus from their marriage life to the education of children.
     
    A common knowledge has it that the unceasing affection & dedication of parents keep their amiable children off all harmful things.
    At the moment, the country is struggling to find out how to heighten the educational level.
     
    I guess the first & critically vital step needs to begin with parents’ ardent zeal, which encourages their adorable children to use a computer mainly for educational needs, and doesn’t accept unqualified teachers.
     
    It might be worth noting that the especially ardent dedication of Mozart’s father is behind his greatness.
