Applying a technology-based system for weight loss in adults with obesity

Area of Science:

• Obesity research
• Behavioral medicine
• Digital health interventions

Background:

• Obesity is a complex health issue requiring effective weight management strategies.
• Traditional in-person behavioral interventions have demonstrated success but face accessibility challenges.

Purpose of the Study:

• To compare the efficacy of in-person, group-based behavioral weight loss interventions with technology-based approaches.
• To evaluate technology-based interventions incorporating wearable devices and monthly telephone support for weight loss in adults with obesity.

Main Methods:

• A 6-month randomized controlled trial involving 39 adults with obesity (BMI 39.5 ± 2.8 kg/m²).
• Intervention groups included standard behavioral weight loss, a technology system with monthly calls (TECH), and an enhanced technology system with monthly calls (EN-TECH).
• All groups received dietary and physical activity guidance; outcomes were assessed at baseline, 3, and 6 months.

Main Results:

• Weight loss at 6 months was -6.57 kg (standard behavioral), -5.18 kg (TECH), and -6.25 kg (EN-TECH).
• Significant reductions were observed in body mass index, waist circumference, and body fat percentage across groups.
• Participants showed decreased energy intake and dietary fat, with increased physical activity.

Conclusions:

• Technology-based interventions, including wearable devices and brief telephone support, are viable options for weight loss in adults with obesity.
• These digital health approaches show comparable outcomes to traditional methods, suggesting potential for broader reach and adherence.
