What is the purpose of this trial?

This trial tests a new method to help men lose weight using a mobile app designed like a video game. The goal is to determine if game-like features, such as digital rewards and team competitions, enhance engagement and effectiveness for weight loss compared to a standard app. The trial involves different groups: some will use the basic app, while others will try the gamified behavioral weight loss treatment. Men who are overweight or obese, enjoy video games, and can walk two city blocks without stopping might be suitable candidates. Participants should also prefer high-calorie foods, as the study aims to improve control over these cravings. As an unphased trial, this study provides a unique opportunity to explore innovative weight loss strategies in a fun and engaging manner.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you have recently started or changed the dosage of a medication that can significantly affect your weight, you may not be eligible to participate.

What prior data suggests that this gamified weight loss program is safe for participants?

Research shows that gamified weight loss programs, like the one under consideration, are designed to make losing weight more enjoyable and effective, particularly for men. These programs use game-like features such as digital rewards and competition to motivate users and encourage healthy habits.

Regarding safety, previous studies on similar gamified mobile health (mHealth) apps have found them to be well-received by users. Reports of negative effects are not significant, as these programs mainly focus on promoting healthier lifestyles through enjoyable and interactive methods.

For the mHealth weight loss treatment, research has also shown that using mobile apps to manage weight is generally safe. These apps help users track their diet and exercise without causing any physical side effects.

Overall, both gamified and non-gamified mHealth weight loss treatments appear to offer a safe way to pursue weight loss. They aim to promote healthier habits without introducing any known health risks. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores the potential of gamification in weight loss programs. Unlike conventional approaches that often focus solely on diet or exercise guidelines, this trial incorporates gaming elements to enhance engagement and motivation. The study investigates both gamified and non-gamified versions of a mobile weight loss program, with some variations using neurotraining techniques. By combining technology with behavioral strategies, researchers hope to discover more effective and enjoyable ways to support weight loss and improve adherence, which could transform how obesity is managed.

What evidence suggests that this trial's gamified weight loss treatments could be effective for obesity?

Research has shown that making weight loss programs more like games can make losing weight more enjoyable and effective for men. Studies have found that adding game-like features, such as digital rewards and competitions, increases motivation and involvement. This trial will test a gamified behavioral weight loss treatment, where one group will receive a fully-gamified version of the program with either sham or active neurotraining.

Another promising approach involves using brain-training games to improve self-control. These games train the brain to resist the temptation of unhealthy foods, which is linked to better weight management. In this trial, some participants will receive a non-gamified program with either sham or active neurotraining to compare its effectiveness.

For programs without game elements, digital tracking of diet and exercise has been shown to aid weight loss by promoting awareness and accountability. Both methods in this trial aim to help men lose weight by making the process more enjoyable and effective. ^{1 2 3 4 6}

Satisfactory completion of all enrollment procedures

Individuals must also provide consent for the research team to contact their personal physician, if necessary, to provide clearance for the prescribed level of physical activity (i.e., walking) or to consult about rapid weight loss

Exclusion Criteria

I have lost 5% or more of my weight in the last 3 months.

I recently started or changed the dose of a medication that may significantly affect my weight.

I have had weight loss surgery in the past.

What Are the Treatments Tested in This Trial?

Interventions

• Gamified behavioral weight loss treatment
• mHealth behavioral weight loss treatment

Trial Overview The study tests a gamified mHealth program against a standard mHealth program for weight loss in men. It includes digital self-monitoring, dietary targets, physical activity, and either a control neurotraining game or an integrated one with team competition and rewards designed to train inhibitory control linked to body mass.

How Is the Trial Designed?

Group I: Gamified program with sham ICT Experimental Treatment 1 Intervention

One group will receive fully-gamified version of the program with a sham.

Group II: Gamified program with Active ICT Experimental Treatment 1 Intervention

One group will receive fully-gamified version of the program with active neurotraining.

Group III: Non-gamified program with Active ICT Active Control 1 Intervention

One group will be assigned to a 12-month mobile weight loss program that includes digital self-monitoring, simplified and self-selected dietary targets (to align with neurotraining and promote autonomy , and behavioral strategies with active neurotraining.

Group IV: Non-gamified program with sham ICT Placebo Group 1 Intervention

One group will be assigned to a 12-month mobile weight loss program that includes digital self-monitoring, simplified and self-selected dietary targets (to align with neurotraining and promote autonomy , and behavioral strategies with sham.

Digital technology can be effectively used for behavioral weight control, particularly through self-monitoring of weight-related behaviors, making it a promising tool for promoting healthy eating and physical activity habits.

Technology-based interventions offer a cost-effective alternative to traditional face-to-face treatments, allowing for broader reach and accessibility to individuals seeking to manage their weight.

A new study will evaluate whether a 12-month weight loss program using reinforcement learning (AI) can achieve similar weight loss results as traditional behavioral weight loss methods, but at a lower cost, involving 336 adults with overweight or obesity.

Preliminary results showed that participants using the AI system needed significantly less coaching while achieving nearly the same weight loss as those in the standard program, suggesting that AI could make weight loss support more accessible.

Automated digital interventions for weight loss showed a small but significant average weight loss of -1.37 kg compared to control groups, based on a systematic review of 66 trials involving 13,672 participants.

The most effective interventions utilized behavior change techniques (BCTs) such as goal-setting and feedback, with social incentive/reward techniques linked to greater weight loss efficacy, although these findings require further validation.

In a study involving 468 adults with obesity, participants who switched to portion-controlled meals (PCM) after being identified as suboptimal responders to standard behavioral weight loss treatment (SBT) lost more weight at 6 months compared to those who switched to acceptance-based treatment (ABT), although the difference was not statistically significant.

Identifying suboptimal responders as early as Session 3 of treatment led to greater weight loss in those switched to PCM compared to those identified later, suggesting that early intervention may enhance the effectiveness of weight loss strategies.
