University of Pittsburgh Medical Center, PA, USA. mcgu...(a)epi.umn.edu BACKGROUND: Previous studies suggest that few individuals achieve long-term weight loss maintenance. Because most of these studies were based on clinical samples and focused on only one episode of weight loss, these results may not reflect the actual prevalence of weight loss maintenance in the general population. DESIGN: A random digit dial telephone survey was conducted to determine the point prevalence of weight loss maintenance in a nationally representative sample of adults in the United States. Weight loss maintainers were defined as individuals who, at the time of the survey, had maintained a weight loss of > or =10% from their maximum weight for at least 1 y. The prevalence of weight loss maintenance was first determined for the total group (n = 500), and then for the subgroup of individuals who were overweight (body mass index BMI > or =27 kg/m2 at their maximum (n = 228). RESULTS: Weight loss was quite common in this sample: 54% of the total sample and 62% of those who were ever overweight reported that they had lost > or =10% of their maximum weight at least once in their lifetime, with approximately one-half to two-thirds of these cases being intentional weight loss. Among those who had achieved an intentional weight loss of > or =10%, 47-49% had maintained this weight loss for at least 1 y at the time of the survey; 25-27% had maintained it for 5 y or more. Fourteen percent of all subjects surveyed and 21% of those with a history of obesity were currently 10% below their highest weight, had reduced intentionally, and had maintained this 10% weight loss for at least 1 y. CONCLUSIONS: A large proportion of the American population has lost > or =10% of their maximum weight and has maintained this weight loss for at least 1 y. These findings are in sharp contrast to the belief that few people succeed in long-term weight loss maintenance. ****** Am J Clin Nutr. 1997 Aug;66(2):239-46 A descriptive study of individuals successful at long-term maintenance of substantial weight loss.Klem ML, Wing RR, McGuire MT, Seagle HM, Hill JO. University of Pittsburgh School of Medicine, PA 15213, USA. The National Weight Control Registry (NWCR) is, to the best of our knowledge, the largest study of individuals successful at long-term maintenance of weight loss. Despite extensive histories of overweight, the 629 women and 155 men in the registry lost an average of 30 kg and maintained a required minimum weight loss of 13.6 kg for 5 y. A little over one-half of the sample lost weight through formal programs; the remainder lost weight on their own. Both groups reported having used both diet and exercise to lose weight and nearly 77% of the sample reported that a triggering event had preceded their successful weight loss. Mean (+/-SD) current consumption reported by registry members was 5778 +/- 2200 kJ/d, with 24 +/- 9% of energy from fat, Members also appear to be highly active: they reported expending approximately 11830 kJ/wk through physical activity. Surprisingly, 42% of the sample reported that maintaining their weight loss was less difficult than losing weight. Nearly all registry members indicated that weight loss led to improvements in their level of energy, physical mobility, general mood, self-confidence, and physical health. In summary, the NWCR identified a large sample of individuals who were highly successful at maintaining weight loss. Future prospective studies will determine variables that predict continued maintenance of weight loss. ***** Annu Rev Nutr. 2001;21:323-41. Successful weight loss maintenance.Wing RR, Hill JO. The Miriam Hospital, Brown University, Providence, Rhode Island 02906, USA. Rw...(a)Lifespan.org Obesity is now recognized as a serious chronic disease, but there is pessimism about how successful treatment can be. A general perception is that almost no one succeeds in long-term maintenance of weight loss. To define long-term weight loss success, we need an accepted definition. We propose defining successful long-term weight loss maintenance as intentionally losing at least 10% of initial body weight and keeping it off for at least 1 year. According to this definition, the picture is much more optimistic, with perhaps greater than 20% of overweight/obese persons able to achieve success. We found that in the National Weight Control Registry, successful long-term weight loss maintainers (average weight loss of 30 kg for an average of 5.5 years) share common behavioral strategies, including eating a diet low in fat, frequent self-monitoring of body weight and food intake, and high levels of regular physical activity. Weight loss maintenance may get easier over time. Once these successful maintainers have maintained a weight loss for 2-5 years, the chances of longer-term success greatly increase. ***** Int J Behav Nutr Phys Act. 2006 Jul 19;3:17 Dietary and physical activity behaviors among adults successful at weight loss maintenance.Kruger J, Blanck HM, Gillespie C. Physical Activity and Health Branch, Division of Nutrition and Physical Activity, Centers for Disease Control and Prevention, Atlanta, Georgia, USA. jkru...(a)cdc.gov BACKGROUND: There is limited population-based data on behavioral factors found to be important for successful weight loss maintenance among adults. METHODS: Data from the 2004 Styles surveys, mailed to U.S. adults aged > or = 18 years were used to examine the difference in selected weight loss strategies and attitudes among persons who reported successful weight loss attempts (lost weight and able to keep it off) and persons who were not successful (previous attempts to lose weight were unsuccessful or they could not keep the lost weight off). Behaviors examined included modification of diet, leisure-time and sports activities, and self-monitoring, and barriers to weight management. RESULTS: Among adults who reported losing weight or trying to lose weight, 31.0% had been successful at both losing weight and maintenance after weight loss. Successful weight loss status differed by sex, age, and current weight status. Assessment of reported weight loss strategies, found that exercising > or = 30 minutes/day and adding physical activity to daily life were significantly higher among successful versus unsuccessful weight losers. Individuals who were successful at weight loss and maintenance were less likely to use over-the-counter diet products than those who were unsuccessful at weight loss. Significantly more successful versus unsuccessful weight losers reported that on most days of the week they planned meals (35.9% vs. 24.9%), tracked calories (17.7% vs. 8.8%), tracked fat (16.4% vs. 6.6%), and measured food on plate (15.9% vs. 6.7%). Successful losers were also more likely to weigh themselves daily (20.3% vs. 11.0%). There were a significantly higher proportion of successful losers who reported lifting weights (19.0%) versus unsuccessful (10.9%). The odds of being a successful weight loser were 48%-76% lower for those reporting exercise weight control barriers were influencing factors (e.g., no time, too tired to exercise, no one to exercise with, too hard to maintain exercise routine) compared to those who reported little or no influence of exercise; similarly, the odds were 48-64% lower for those who found certain dietary barriers to be influential (e.g., eat away from home too often, diet/health food costs too much). CONCLUSION: Self-monitoring strategies such as weighing oneself, planning meals, tracking fat and calories, exercising 30 or more minutes daily, and/or adding physical activity to daily routine may be important in successful weight loss maintenance. Leisure-time activities such as lifting weights or cooking/baking for fun are common strategies reported by those who were successful weight losers. ****** Int J Obes Relat Metab Disord. 1998 Jun;22(6):572-7 McGuire MT, Wing RR, Klem ML, Seagle HM, Hill JO. University of Pittsburgh Medical Center, PA 15213, USA. OBJECTIVE: To evaluate whether individuals who lost weight on their own (n = 447), through organized programs (n = 313) or with liquid formula (n = 133) would differ in the strategies they used to maintain their weight losses. DESIGN: All subjects were members of the National Weight Control Registry, had lost > or = 13.6 kg (30 pounds), and kept it off at least one year (mean weight loss = 30.1+/-14.9 kg and mean duration of maintenance = 5.7+/-6.9 y). RESULTS: Liquid Formula users differed from the other two groups on many characteristics; they were more likely to be women, older, heavier, and to have had a medical disorder prior to weight loss. To maintain their weight loss, the Liquid Formula group reported greater use of dietary strategies (for example, counting calories, limiting the amount of calories from fat) and higher dietary restraint. Liquid Formula users reported that weight maintenance was more difficult than losing weight, whereas individuals who lost weight on their own reported the reverse. The On Own group reported expending a higher percentage of calories through strenuous activities such as running and weight lifting, and reported weighing themselves more frequently to maintain weight loss. Despite these behavioral differences, all three groups are maintaining their weight losses similarly by eating a low calorie diet (5792.3 kJ/d and 25% of daily calories from fat) and engaging in high levels of physical activity (11847.3 kJ/week). CONCLUSIONS: Despite using different methods to lose weight, individuals who lost weight on their own, through an organized program, or with a liquid formula, use similar behavioral strategies to maintain their weight loss. ***** Int J Obes Relat Metab Disord. 2001 Mar;25(3):325-31 Weight-loss maintenance in overweight individuals one to five years following successful completion of a commercial weight loss program.Lowe MR, Miller-Kovach K, Phelan S. Department of Clinical and Health Psychology, MCP Hahnemann University, Philadelphia, Pennsylvania 19102, USA. l...(a)drexel.edu OBJECTIVE: To determine weight loss maintenance among participants in a commercial weight loss program (Weight Watchers) who had reached their goal weights 1-5 y previously. DESIGN: A national sample (n=1002) was surveyed by phone to obtain demographic and weight-related information. An oversample (n=258) was recruited and weighed in person to develop a correction factor for self-reported weights in the national sample. RESULTS: Based on corrected weights, weight regain from 1 to 5 y following weight loss ranged between 31.5 and 76.5%. At 5 y, 19.4% were within 5 lb of goal weight, 42.6% maintained a loss of 5% or more, 18.8% maintained a loss of 10% or more, and 70.3% were below initial weight. CONCLUSIONS: These results are not directly comparable to those obtained in clinical settings because of differences in the populations studied. Nonetheless, they suggest that the long-term prognosis for weight maintenance among individuals who reach goal weight in at least one commercial program is better than that suggested by existing research. *****
