Il 4 March every year, the World Obesity Day, an international event that draws attention to one of the fastest-growing chronic diseases in the world. According to the World Health Organization, there are over 800 million adults with obesity globally, a number that in recent decades has almost tripled compared to the recent pastIn Italy, the emergency is real: approximately 5,6 million people are obese, equal to over 11% of the adult population., with nearly half of adults living with overweight or obesity overall. These numbers underscore the importance of effective preventive strategies, including adopting healthy eating habits.
Obesity and extra virgin olive oil
Among the dietary factors investigated for their role in prevention and in weight control, extra virgin olive oil – the cornerstone of the Mediterranean diet – has received growing attention from the scientific community. While it may seem counterintuitive to talk about a calorie-rich food in the context of obesity (oil provides about 9 kcal per gram), studies suggest that the quality of fats and the presence of bioactive compounds can positively influence metabolism and body fat distribution.
An observational study recently published in Frontiers in Nutrition analyzed data from over 16,000 adults, highlighting that Regular consumption of extra virgin olive oil is associated with a reduction in abdominal obesity, measured by waist circumference and body mass index. The data suggest that those who include EVOO as the main source of fat in the Mediterranean diet tend to have a more favorable metabolic profile, with a lower body mass index and body fat distribution than those who consume it sporadically or in smaller quantities.
Le reasons for these benefits are to be found not only in the monounsaturated fatty acid profile, in particular oleic acid, but also in the richness of polyphenols including hydroxytyrosol, oleuropein, oleocanthal and oleaceinThese compounds, present in higher quantities in high quality extra virgin olive oil, have been shown in preclinical and clinical studies to have anti-inflammatory, antioxidant and metabolic effectsThese effects may contribute to improved insulin sensitivity, reduced oxidative stress, and optimized lipid metabolism, all of which are implicated in the genesis and maintenance of obesity and its metabolic complications.
An emblematic example is represented by studies on animal models, like the one published on Scientific Reports, In which high-fat diets enriched with extra virgin olive oil They produced improvements in insulin sensitivity and body weight control, reducing some markers of metabolic dysfunction. Similarly, analysis of specific polyphenols showed how these compounds modulate adipogenesis and inflammation in adipose tissue, opening up interesting prospects for integrated nutritional strategies.
It is important to point out that Extra virgin olive oil alone cannot work miracles. However, inserted inside a balanced food basket – such as the Mediterranean diet – can play a significant role in weight management and the prevention of metabolic comorbidities.
In conclusion, while obesity continues to represent a public health challenge in Italy and worldwide, current scientific evidence supports the role of extra virgin olive oil as a nutritional component which, thanks to its unique composition, may help promote a more favorable metabolic profile and support long-term preventive strategiesWorld Obesity Day is therefore also an opportunity to reflect on how informed, evidence-based food choices can make a difference in individual and collective health.
