Weight reduction using a formula diet recovers menstruation in obese patients with an ovulatory disorder

To determine the effectiveness of a formula diet in weight reduction and the recovery of menstruation in obese patients with ovulatory disorders.

After the enrollment of 39 obese women with ovulatory disorders, they replaced one or two of their three normal meals with a microdiet (MD) (240 kcal/meal) for 24 weeks. Physical, endocrinological, and biochemical tests were conducted before and at 12 and 24 weeks of the study. Of the 39 women enrolled, 26 were not taking clomiphene. They were divided into three groups according to their body weight outcomes and then analyzed for menstruation recovery.

A weight reduction of ≥5% was observed in 31 (81.5%) of the 39 women. There were significant decreases in the body weight and Body Mass Index during the study. Menstruation returned in 18 (69%) of the 26 patients without clomiphene treatment, with the recovery being significantly more prevalent in the groups (totally 81.0%) that exhibited a 5%-10% weight reduction and ≥10% weight reduction, compared to the group with a <5% weight reduction.

The use of a formula diet effectively reduced the patients' body weight and led to the recovery of menstruation in these obese patients with ovulatory disorders.
