Details on the eating habits of the participants were collected through a consumption frequency questionnaire. The authors discovered that those who consumed three dairy products a day gained half the weight and had a waist circumference that measured 15% less compared to those who consumed one dairy product or less daily.
Another interesting finding: those who consumed 100 g or more of yoghurt a day gained, on average, half the weight and had a waist circumference that measured 20% less compared to those who consumed 30 g of yoghurt a day or less. Among the implied mechanisms the researchers quote the favourable role of calcium on weight control, as well as that of ferments, bioactive yoghurt peptides and conjugated linoleic acid.
