The current meta-analysis showed that adherence to the Mediterranean diet was associated with a lower risk of overweight/obesity and less weight gain.
The Mediterranean diet (Med Diet) – mainly a plant-based diet including moderate wine consumption – is regarded as one of the healthiest diets. A long-term adherence has been related to a lower risk of degenerative diseases such as cardiovascular disease, diabetes, cancer, metabolic syndrome, etc. Overweight and obese individuals are more likely to develop type 2 diabetes, CVD, and many cancers and have an increased risk of dying.
Considering the high prevalence of obesity and its relation to chronic diseases, it is necessary to maintain a healthy weight.
Findings from earlier studies examining the relationship between the adherence to the Med Diet and overweight/obesity are inconsistent and the current research systematically reviewed all the published prospective studies which investigated this association.
The findings of this meta-analysis revealed that a higher adherence to the Med diet was linked to a lower risk of overweight and/or obesity as well as with less weight gain in adults during the 5 years of follow-up. As possible explanation, the authors referred to the high fiber content of fruits and vegetables which could provoke satiety and a sensation of fullness.
