“…This study was part of the ongoing Healthy Families Healthy Forces (HF2) randomized controlled trial (trial # NCT02348853). Briefly, the HF2 study compares GLB with a different behavioral weight loss intervention 8 for changes in body weight and cardiometabolic risk factors in adult family members of active duty military personnel or retired military personnel. Participants in the subgroup reported herein were randomized to the GLB arm of the larger trial, and were assigned to either in-person or videoconference groups depending on their date of enrollment and location.…”

“…Such approaches have been tested in civilian populations, and preliminary studies indicate weight loss is similar in magnitude to in-person interventions. 7,8 However, to our knowledge, there has been no evaluation of the effectiveness of videoconference approaches to address overweight and obesity in families with active duty military service members.…”

“…Group Lifestyle Balance (GLB) 9,10 is the official community-adapted version of the Diabetes Prevention Program 11,12 and is in widespread use. The few videoconference implementations of GLB reported suggest it can be effective in civilian populations, 8,13–15 and retired service members 16 but no videoconference adaptation has been described in sufficient detail to allow replication. Furthermore, no adaptation has been reported for military families, and the studies published to date in other populations lack control groups or comparative in-person implementation groups, which limits evaluation of program integrity and effectiveness of the videoconference delivery format.…”

IntroductionEffective, standardized, and easily accessible weight management programs are urgently needed for military beneficiaries. Videoconference interventions have the potential for widespread scaling, and can provide both real time interaction and flexibility in delivery times regardless of location, but there is little information on their effectiveness and acceptability.Materials and MethodsThis study as part of a larger weight loss trial describes the videoconference adaption of Group Lifestyle Balance (GLB) program, a community group-based Diabetes Prevention Program intervention, and provides a comparison of weight loss and meeting attendance between in-person and videoconference delivery modes over 12 weeks in adult family members of military service members. Forty-three participants were enrolled from two military installations and received either the videoconference-adapted or an in-person GLB program in a non-randomized trial design. Differences in program attendance and percent weight lost at 12 weeks were compared by independent samples t-tests and nonparametric methods. Group differences in the percentage of weight lost over the 12-week period were analyzed using a linear mixed model.ResultsAll GLB intervention components were successfully delivered by videoconference with minor adaptations for the different delivery mechanism. Participant retention was 70% and 96% in the in-person and videoconference groups, respectively (p = 0.04). Completing participants in both groups lost a significant percent body weight over the 12 week intervention (p < 0.001) and there was no difference in percent body weight after 12 weeks of intervention (6.2 ± 3.2% and 5.3 ± 3.4% for in-person and videoconference at 12 weeks, respectively; p = 0.60).ConclusionThis study describes the first videoconference adaption of the GLB program for use in military families. Attrition was lower in the videoconference group, and there were a similar levels of weight loss in both groups regardless of delivery modality. Videoconference weight loss interventions are effective and feasible for scaling to support healthy weight management in military as well as civilian populations.

“…A number of studies have used videoconference technology to deliver health coaching interventions . In observational analyses of commercial weight loss participants, a 2017 study reported that videoconference participants were more likely to complete the 11‐week programme but not more likely to lose weight . Most recently, a study team reported from two randomized trials (one of 25 and one of 30 adults with obesity) that those randomized to videoconference arms had significantly greater 12‐week weight loss than those randomized to either in‐person or usual care arms .…”

Summary Objective New communication technologies have shown some promise in lifestyle weight loss interventions but may be most effective when leveraging face‐to‐face communications. The study reported here sought to test whether weight loss programme attendance and outcomes are greater when offered in‐person at community sites or remotely via videoconference vs. in Federally Qualified Health Centers (FQHCs). In a three‐arm randomized trial among 150 FQHC adults, intervention delivery in community‐sites or via videoconference was tested against a clinic‐based lifestyle intervention (enhanced usual care [EUC]). Methods Twice weekly, a nutrition topic was reviewed, and exercise sessions were held in a 20‐week programme delivered either in community settings or via videoconference. The primary outcome was the proportion of participants losing more than 2 kg at 6 (end of treatment) and 12 months in intent‐to‐treat analyses. Results Mean (SD) age was 53 years, 82% were women, 65% were African–American, 50% reported $18,000 or less household income and 49% tested low in health literacy, and mean (SD) body mass index was 39 kg m −2 . The proportion losing more than 2 kg of weight in the community site, videoconference and EUC groups was 33%, 34% and 24%, respectively, at 6 months and 29%, 34% and 29% at 12 months. No differences reached significance. Attendance was poor in all groups; 45% of community site, 58% of videoconference and 16% of EUC participants attended at least one session. Conclusion Videoconference and community‐based delivery were as effective as an FQHC‐based weight loss programme.

Physiological adaptations to intentional weight loss can facilitate weight regain. This review summarizes emerging findings on hypothalamic and brainstem circuitry in the regulation of body weight and identifies promising areas for research to improve therapeutic interventions for sustainable weight loss. There is good evidence that body weight is actively regulated in a homeostatic fashion similar to other physiological parameters. However, the defended level of body weight is not fixed but rather depends on environmental conditions and genetic background in an allostatic fashion. In an environment with plenty of easily available energy‐dense food and low levels of physical activity, prone individuals develop obesity. In a majority of individuals with obesity, body weight is strongly defended through counterregulatory mechanisms, such as hunger and hypometabolism, making weight loss challenging. Among the options for treatment or prevention of obesity, those directly changing the defended body weight would appear to be the most effective ones. There is strong evidence that the mediobasal hypothalamus is a master sensor of the metabolic state and an integrator of effector actions responsible for the defense of adequate body weight. However, other brain areas, such as the brainstem and limbic system, are also increasingly implicated in body weight defense mechanisms and may thus be additional targets for successful therapies.

Abstract: iDiet participants had clinically impactful mean WL. The observed high mean WL in worksites and videoconference-delivered programs broadens options for scalable WL program implementation.
