Key Takeaway
Consider group visits over individual sessions for patients with high self-esteem to potentially improve weight loss outcomes.

This cluster randomized controlled trial enrolled 1220 rural primary care patients with obesity to evaluate the impact of delivery format on weight loss over a 24-month period. The study compared group visits for lifestyle components of comprehensive obesity treatment against individual visits.

For patients with self-esteem scores greater than 60, the study reported superior weight loss in the group intervention versus individual treatment (posterior probability of 0.999). For the subgroup with the highest self-esteem scores (80 to 100), participants in the group setting lost 6.7 kg compared to 3.9 kg in the individual setting. The 95% CI for the group was -8.15 to -5.20, and the 95% CI for the individual intervention was -5.45 to -2.39.

No data regarding adverse events, serious adverse events, or discontinuations were reported. The study utilized a Bayesian normal dynamic linear model with a changepoint parameter to estimate results. Clinical application may be limited by the specific population of rural primary care patients and the reliance on self-reported esteem scores as a predictor for intervention success.

How this fits prior evidence

How this fits prior evidence: This finding addresses a gap in behavioral delivery methods for obesity management. While previous coverage highlighted pharmacological options like semaglutide for weight loss and blood pressure management, and dietary interventions such as intermittent fasting plus early time-restricted eating, this study provides specific evidence on the efficacy of group versus individual counseling formats based on patient self-esteem scores.

Managing weight is often a lonely journey, and for many people, the mental toll can be just as heavy as the physical one. A new study looked at how different types of support affect weight loss in rural patients who were struggling with obesity.

Researchers compared two ways of providing lifestyle advice: group visits versus individual visits. They found that for patients with a self-esteem score above 60, those in the group setting lost significantly more weight than those seen individually. For people with the highest self-esteem scores (between 80 and 100), the difference was even clearer. These individuals in groups lost about 6.7 kilograms, while those in individual sessions lost 3.9 kilograms.

While these results suggest that group settings can offer a boost for certain people, it is important to remember that everyone's journey is unique. The study specifically highlights how social support might help those whose self-esteem scores are above 60. Talk to your doctor about which setting might best fit your personal goals and needs.

What this means for you:
Patients with lower self-esteem may lose more weight in a group setting than during individual visits.

Common questions

Who would benefit most from a group setting for weight loss?

The study suggests that patients with self-esteem scores above 60 may see better results in a group setting. Specifically, those with the highest self-esteem scores (between 80 and 100) lost 6.7 kg in a group versus 3.9 kg during individual visits.

How much weight was lost in the study?

For patients with high self-esteem scores, those in the group setting lost an average of 6.7 kg over 24 months. In contrast, those who received individual visits lost about 3.9 kg during that same time.

Is it safe to join a weight loss group?

The study did not report any specific safety data or adverse events for either the group or individual visit models. You should speak with your healthcare provider to determine which treatment plan is safest and most effective for your personal health needs.

OBJECTIVE: Patients with obesity report experiencing weight stigma resulting in poor self-esteem. Based on baseline self-esteem, this paper explores recommendations for group versus individual visits for lifestyle components of comprehensive obesity treatment in primary care. METHODS: Participants (n = 1220) were rural primary care patients in a 24-month cluster randomized controlled trial that demonstrated superior weight loss with group versus individual treatment. Baseline weight-related self-esteem scores (0-100), as measured by the Impact of Weight on Quality of Life-Lite (IWQOL-L), were used. A Bayesian normal dynamic linear model with a changepoint parameter estimates the relationship between self-esteem and weight loss across group versus individual treatment at the 24-month primary endpoint. RESULTS: The posterior probability that patients receiving group lost more weight than those receiving individual visits remained  0.999 for patients with self-esteem scores greater than 60. Those with the highest self-esteem (scores 80-100) receiving group visits lost 6.7 kg (95% CI, -8.15 to -5.20) at 24 months compared to 3.9 kg (95% CI, -5.45 to -2.39) for those receiving individual visits. CONCLUSIONS: People may benefit more from group than individual intervention if their self-esteem is above an IWQOL-L score of 60 when starting an intensive behavioral intervention for weight loss.
