Brief Summary

The study of the pro-inflammatory activation of circulating monocytes/macrophages in obesity is the main problem of this project. The investigation of pro-inflammatory activation of monocytes and determination of the level of mitochondrial genome mutations, assessment of traditional CVD risk factors and the degree of cardiovascular risk and atherosclerosis indicators and their association will be investigated in dynamics on 12-weeks weight loss.

Study Arms (3)

Obese Weight Loss group

EXPERIMENTAL

Low-calorie diet and regular physical trainings will be administered to obese participants (BMI \>30kg/m\^2).

Behavioral: Lifestyle Modification

Obese Control group

ACTIVE COMPARATOR

Traditional weight loss recommendations will be provided to obese participants (BMI \>30kg/m\^2)

Behavioral: Traditional Recommendations

Lean Control group

NO INTERVENTION

The data of these subjects will be used as a control

Interventions

An individualized low-calorie diet is characterized by sugars and starchy food intake restriction, 500 kcal daily energy deficit for 12 weeks (3 months). Regular physical activity is represented by individualized 30 minutes trainings on an anti-gravity treadmill 3 workouts per week for 12 weeks with individual targets of stepping activity, which will be evaluated according to personal fitness monitoring data

Obese Weight Loss group

The list of traditional diet and physical activity recommendations for patients with obesity
