  Purpose

More than 1,000 obese people are screened for genetic mutations (MC4R). Those with positive screenings as well as 320 randomly selected people without MC4R mutations are randomized to 2 consultation types: one including recommendations for eating and physical activity behavior, the other with an additional part on genetic determinants and actions in obesity. It is hypothesized that obese people with obesity-specific genetic mutations, and obese people with a family history of obesity, benefit more if the consultation includes additional elements on genetic determinants.

Detailed Description:

More than 1,000 obese people are screened for genetic mutations (MC4R). Those with positive screenings as well as 320 randomly selected people without MC4R mutations are randomized to 2 consultation types: one including recommendations for eating and physical activity behavior, the other with an additional part on genetic determinants and actions in obesity. Their results are compared to a control group (n>100). It is hypothesized that obese people with obesity-specific genetic mutations, and obese people with a family history of obesity, benefit more if the consultation includes additional elements on genetic determinants.

The following variables are used: BMI, SCID interview for mental disorders, Stunkard's body silhouttes for participants and their parents and siblings, Restraint Eating Scale, PANAS, Well-being scale, body acceptance, shame and guilt, coping with obesity, participant's satisfaction with consultation.

Assessment Points: before consultation, after consultation, 6 months later.
