Study participants and methods

Researchers randomly assigned 182 individuals to the Mediterranean group and 178 to the control group. The average age of participants was 55, and most had a BMI of 30 or greater. Many also suffered from chronic conditions like diabetes and hypertension.

Weight loss outcomes

Both groups lost a similar amount of weight over the 24-month period. Assessments took place at four, twelve, and twenty-four months to track progress. Experts note that calorie balance remains important for achieving weight loss.

Diet quality differences

The Mediterranean-style group saw greater improvements in overall diet quality than the control group. Participants on this diet were more likely to recommend the program. Choosing higher-quality foods provided additional benefits for overall health beyond weight loss.
