Diet has a major role in the etiology of obesity, and there is a growing body of evidence suggesting that a variety of dietary factors can modulate obesity-induced chronic low-grade inflammation and thus the course of obesity-related chronic non-communicable diseases. The present intervention study aims to evaluate the effect of an anti-inflammatory diet on weight loss, body composition, cardiometabolic risk factors and immune system response among young adults of the obese younger adults.
Obesity pandemic presents a major challenge to chronic disease prevention worldwide. A low-grade chronic inflammation is associated with obesity and related cardiometabolic disorders, such as cardiovascular diseases, type 2 diabetes and some type of cancers. Diet has a major role in the etiology of obesity, and there is a growing body of evidence suggesting that a variety of dietary factors can modulate obesity-induced chronic low-grade inflammation and thus the course of obesity-related chronic non-communicable diseases. The present intervention study aims to evaluate the effect of an anti-Inflammatory diet on weight loss, body composition, cardiometabolic risk factors and immune system response among younger adults. A nutritional intervention based on an energy-restricted anti-inflammatory diet will be compared with an isocaloric standard diet (55-60% carbohydrates, 25% fat, 15-20% protein). The inflammatory potential of the diet will be assessed with the Dietary Inflammatory Index®.

During 6 months the participants will we asked to use recommended energy-reduced diet with anti-inflammatory properties, based on colorful vegetables and fruits, legumes, nuts, seeds, marine fish, whole-grain products, and daily use of olive oil, green/black tea, multiple spices and herbs.
During 6 months the participants of control group will be asked to use recommended energy-reduced diet based on standard obesity management (55-60% carbohydrates, 25% fat, 15-20% protein)
