Endocrine Today has compiled a list of the top five news reports posted from ObesityWeek from Nov. 1 to Nov. 6.

Healio.com/Endocrinology readers were interested in the effects of non-nutritive sweeteners, the effect of a diet coupled with physical activity, and much more.

Non-nutritive sweetener effects may contribute to insulin resistance in consumers with obesity

NEW ORLEANS — Sucralose, a no-calorie sweetener widely used in beverages, may adversely affect glucose metabolism in consumers with obesity, according to a presenter here.

“There seem to be differential effects of sucralose on glucose metabolism in normal-weight people and in people with obesity, so previous findings in lean subjects cannot be extrapolated to what will be the effects of sucralose in subjects with obesity (and vice versa),” Marta Yanina Pepino De Gruev, PhD, assistant professor in food science and human nutrition at the University of Illinois in Urbana, told Endocrine Today. “Clinicians may find surprising that sucralose is not metabolically inert, as generally thought, at least for people with obesity.” Read more.

Diet plus physical activity increases fitness

NEW ORLEANS — Adding physical activity to diets does not induce additional weight loss compared with diet alone, according to a presenter here.
“We wanted to examine whether the public health recommendation of 150 minutes a week of physical activity or the widely accepted 200 to 250 minutes of moderate to vigorous physical activity affects health outcomes in terms of physical activity, weight loss and fitness compared to a group that had the same diet program but did not have a prescription for physical activity,” John M. Jakicic, PhD, chairperson of the department of health and physical activity, the Physical Activity and Weight Management Research Center at the University of Pittsburgh, said during his presentation.

Daily texting feedback effective for weight loss

NEW ORLEANS — Financial incentives for weight loss may not increase reductions; however, daily texting feedback may be effective.

“Self-monitoring with daily weighing, particularly when combined with text message feedback, is an effective weight-management strategy,” William S. Yancy, Jr., MD, MHS, FTOS, director of Duke University Diet and Fitness Center, told Endocrine Today. “Different types or higher amounts of incentives than those tested may enhance this strategy.” Read more.

Weight loss in untreated spouses tied to interventions in partners

NEW ORLEANS — The effects of weight loss in adults randomly assigned to Weight Watchers or self-guided weight loss may have an impact on untreated spouses’ weight loss.

“We actually know quite a bit about different relationships and how weight might function within certain relationships,” Amy Gorin, PhD, associate professor at the University of Connecticut, said during her presentation. “The relationship that has received the most research attention is the marital dyad. We know that spouses’ weights tend to be correlated at the start of marriage, and they tend to change in similar fashion over time, and that is typically toward weight gain. Weight gain within the first year of marriage and then throughout the marriage is very common.” Read more.

Parent weight loss influences adolescent weight loss

NEW ORLEANS — Weight loss in parents may be influential on adolescents’ weight loss over time, study data show.

“Parent obesity is related to child weight so that children who are overweight or obese often have parents who are overweight or obese,” Jaqueline Hayes, MA, a graduate student in the department of psychiatry at Washington University in St. Louis, said during her presentation. “We know that in family-based treatment, when parents are targeted for weight loss along with their child, that parent weight loss is an independent and robust predictor of child weight loss. Children who are losing the most weight also have parents who are losing the most weight.” Read more.
