Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Since overweight and obesity, a risk factor for various diseases, is a prevalent problem in the modern society, it is important to search for new strategies to counteract this. In contrast to in person support, the internet provides a low cost opportunity, which is able to reach a large part of the population. Therefore a web-based weight loss program may be an adequate mean for many people. Now it is hypothesised that a web-based weight loss program is able to support a reduction of body weight and weight-related cardiovascular risk factors effectively and to promote a healthier lifestyle. It is expected that program use, compared to a control group, results in greater reductions in body weight and cardiovascular risk.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

KiloCoach

Study subjects use the KiloCoach program on at least 4 days per week within the first half of the 6 months intervention period. In the second half, program usage is ad libitum.

Group Type EXPERIMENTAL

KiloCoach

Intervention Type OTHER

Study participants in this arm will use the program to record nutrition and physical activity on at least 4 days per week within the first and ad libitum within the second 3 months of the intervention period.

Study visits will be conducted at baseline as well as after 1, 3 and 6 months. After 12 months a follow up visit will be conducted.

Control

Study subjects try to reduce body weight on their own, without participating in an organized weight loss program, over a period of 6 months.

Group Type NO_INTERVENTION

Control

Intervention Type OTHER

Study subjects try to reduce their body weight on their own. They are free to exercise and/or change nutritional habits. Not allowed is taking part in any structured weight loss program.

Study visits will be conducted at baseline as well as after 1,3 and 6 months. A follow up visit will be conducted after 12 months.
