Shedding consistent pounds each week linked to long-term weight loss

When it comes to losing weight, it's not necessarily slow, but steady, that wins the race, according to new research from Drexel University.

In a study of 183 participants, those whose weights fluctuated the most during the first few weeks of a behavioral weight loss program ultimately had poorer weight loss outcomes one and two years later, compared to the men and women who lost a consistent number of pounds each week. The results were published today in the journal Obesity.

"It seems that developing stable, repeatable behaviors related to food intake and weight loss early on in a weight control program is really important for maintaining changes over the long term," said lead author Emily Feig, PhD, a former graduate student in the College of Arts and Sciences at Drexel University.

The psychologists were interested in studying what makes some people less successful in weight loss programs and identifying predictors that could improve treatment outcomes in the future.

To find out, they enrolled individuals who were overweight or obese into a year-long weight loss program that used meal replacements along with behavioral goals such as self-monitoring, calorie monitoring and increasing physical activity. The participants attended weekly treatment groups during which they were weighed, and returned for a final weigh-in two years from the start of the program. The participants also reported on food-related behaviors and attitudes like cravings, emotional eating, binge eating and confidence in regulating intake.

The researchers found that higher weight variability over the initial six and 12 weeks of weight loss treatment predicted poorer subsequent, long-term weight control at 12 and 24 months. For example, someone who lost four pounds one week, regained two and then lost one the next tended to fare worse than someone who lost one pound consistently each week for three weeks.

Interestingly, individuals who reported lower emotional eating, binge eating and preoccupation with food at the start of the study showed higher weight variability and less weight loss overall. This suggests that initial weight change, rather than relationships with or behaviors toward food, is much more important in predicting who will succeed in weight loss and maintenance.

Exactly why some people have more weight variability than others is a question the researchers are interested in exploring in future studies.

Though he is hesitant to equate correlation and causation in this case, principal investigator Michael Lowe, PhD, a psychology professor at Drexel, says the study does illuminate a potential method for sticking to weight loss goals.

"Settle on a weight loss plan that you can maintain week in and week out, even if that means consistently losing ¾ of a pound each week," he said.

If future studies can replicate these results, then measuring weight variability may be a way to identify individuals who are less likely to achieve meaningful and sustainable weight loss, and who may benefit from a stronger, more tailored focus on consistency.

I don't really understand why this would be the take-home. You can see how these folk go in with a bias towards behaviour as a cause for obesity. So they have a behaviour modification based intervention. Lower emotional eating, binge eating and preoccupation with food associated with higher weight variability and less weight loss overall. Wouldn't you predict that a behaviour modification intervention, intended to decrease binges, emotional eating and food preoccupation would be least successful, in the long term, for people who didn't have a problem with these in the first place? How exactly is behaviour modification supposed to do you any good if the behaviours addressed had nothing to do with your obesity in the first place? Especially if the behaviour they're trying to modify you towards is healthywholegrains and such slop.
