“The results of our study, the first to demonstrate the impact of probiotics-supplemented dietary counselling on adiposity, were encouraging,” said Kirsi Laitinen, a nutritionist and senior lecturer at the University of Turku in Finland who presented her findings on May 7 at the European Congress on Obesity. “The women who got the probiotics [during pregnancy and until the women stopped breast feeding] fared best. One year after childbirth, they had the lowest levels of central obesity as well as the lowest body fat percentage.”
That’s a unusual way to look at the data. Most studies of weight control look at weight change so as to adjust for individual differences. Maybe pre-pregnancy weights were not avaiable.
