Of the people who start the Combined Lifestyle Intervention (GLI), about 60 percent completes the entire program. This is evident from in-depth research by the RIVM. The GLI is a two-year lifestyle program. In the first year, slightly more people drop out (27 percent) than in the second year (20 percent). The RIVM concludes that the GLI benefits from more customization to reduce the dropout rate.

Dropout does decrease over the years, as this new report shows. Of the participants who started in 2019, half dropped out early. For participants who started in 2022, this was still 38 percent. Furthermore, it also appears that most people (90 percent) actually start the GLI after an intake interview.

Reasons for dropping out early

The reasons for not completing the GLI (external link) vary by participant. A significant reason for participants to stop is if the program does not meet their needs. For example, if they receive too little new knowledge or practical tools. Another reason is that they do not have a good rapport with the coach or group. Some participants also stop due to mental or physical issues.

Better explanation about GLI

The RIVM spoke for this research with lifestyle coaches, general practitioners, and participants. They indicate that it is important to explain what the GLI entails even better during the intake. Furthermore, they believe it is important for general practitioners to see if people need other help before referring them to the GLI.

More customization

The interviewees also see areas for improvement for the program. This includes more customization where guidance is tailored to personal situations and preferences. Additionally, lifestyle coaches want to be better trained, especially for guiding groups. The RIVM advises further investigation into whether more customization in the GLI is feasible. This additional customization may also require extra budget. Furthermore, the RIVM advises lifestyle coaches to share successful experiences and practices more with each other.  

About the GLI

The GLI focuses on healthy eating and exercise. There is also attention to themes that are not conducive to a healthy lifestyle, such as stress and poor sleep. Health insurers have reimbursed the GLI since 2019. The RIVM monitors the developments of the GLI on behalf of the Ministry of VWS Ministry of Health, Welfare and Sport (Ministry of Health, Welfare and Sport). Earlier research (external link) showed that participants lost an average of 5 percent of their weight after completing the GLI. Additionally, their quality of life improved significantly.
