Lifestyle patterns related to weight-loss maintenance [abstract] Abstract uri icon


  • In order to identify phenotypical behavioral patterns related to obesity, Fuglestad et al. (2012) factor analyzed an array of weight control and lifestyle behaviors in a sample of people who had lost weight on their own initiative (.10 % loss in the past year). Four behavioral factors were identified—regularity of meals, TV related viewing and eating (e.g., eating meals in front of the TV), intentional weight control strategies (e.g., calorie counting, self-weighing), and eating away from home. Utilizing the same sample, the present investigation examined the stability of these factors over time and the associations of these factors with weight change. Participants in a weight maintenance intervention completed behavioral measures and were weighed at baseline, 6, 12, 18, and 24 months (N=419; 82 % female; 87 % white; age M=47). The four behavioral factors emerged at each time point, although the eating away from home factor was narrower—only fast food and convenience stores. Linear mixed models tested the independent associations of these factors with weight change and weight maintenance (i.e., gaining <25%of lost weight). Increases in TV-related eating and viewing were related to increases in weight (ã=1.99, t=4.30, p<.0001) and decreases in weight maintenance (ã=..31, t=.2.74, p=.006). Increases in fast/convenience food were related to increases in weight (ã=1.30, t=4.30, p=.013). Increases in weight control strategies were related to decreases in weight (ã=.2.97, t=6.80, p<.0001) and increases in weight maintenance (ã=.43, t=2.95, p=.003). Counter to expectation, meal regularity was not related to weight outcomes, suggesting that this may be an overemphasized behavior. Overall, results suggest that a regulated and ordered lifestyle—consisting of intentional weight control strategies and limited fast food and TVrelated eating and viewing—is important for maintaining weight loss. In future research, it will be crucial to link these behavioral patterns to environmental, biological, and psychological influences on obesity.
