PlumX metrics:
It is proven that life style modification (diet and physical exercises) have positive effect on the metabolic functions in pa-tients with obesity, even without significant weight reduction.

Aim of the study:
The objective of the present study was to check whether the intensive controlled lifestyle intervention (personalized diet modification and monitored, regular physical activity) may have positive impact on the concentration of irisin and chemerin in children with obesity.

Material and methods:
Twenty children (mean age 8.9) were included in the prospective, cross-over study. They were randomly assigned to group A (with three months intensive intervention), and B (standard intervention). After three months, the groups were switched.

Mean irisin level increased significantly after the phase of intensive intervention (4.8 to 5.1 µg/ml; p = 0.03), regardless of whether the intervention was applied from the beginning (Group A) or after 3 months from the advice of healthy-lifestyle (Group B). A period without intensive monitoring was associated with a significant reduction of irisin level. For chemerin in the group A (starting from intensive intervention) mean level decreased after the phase of intensive intervention (65.8 to 57.0 ng/ml), and then increased to 67 ng/ml during the standard intervention. In the group B after the standard intervention period chemerin level increased 67.5 to 68.8 ng/ml (p = 0.03), and then after introduction the intensive intervention de-creased to 63.7 ng/ml.

Personalized diet modification and regular, daily exercises may positively influence on the levels of irisin and chemerin.
