This study analysed the evolution of weight gain and waist circumference among participants in the Framingham Heart Study, between 1991 and 2008.
The results reveal that the participants who consumed at least three portions of dairy products a day gained, on average, 0.1 kg less than those who consumed less than one portion a day.
There is also a significant correlation between the weekly consumption of at least three portions of yoghurt and both lower yearly weight gain (-0.1 kg) and a smaller increase in waist circumference (-0.13 cm) compared to those consuming less than one portion a week.
