A cknowledgmentsWe thank all the participants for their excellent collaboration. Methods: Thirty-eight men and 32 premenopausal women (24-53 years) were exposed to the same 4-week experimental MedDiet during which all foods were provided to participants. Participants also received some recommendations/tools to adhere to a healthy way of eating, with no other contact until the 6-month follow-up visit.Results: Compared to baseline, the Mediterranean score (MedScore) had increased at the end of the 6-month follow-up (time effect P=0.003), with no gender difference (gender-by-time interaction P=0.97). Although our intervention was not focused on body weight management, compared to baseline, BMI decreased during the intervention in both men and women (respectively P<0.0001 and P=0.03); however, only the female participants of this study managed to maintain the lower BMI, six months after the intervention (P=0.03 for women;gender-by-time interaction P=0.04).Conclusions: Exposure to the MedDiet for a short duration promotes the adherence to this food pattern in both genders and helps in the management of body weight, especially in women.
