To mimic this obesogenic environment, the teams led by Mara Dierssen at CRG and Rafael Maldonado at UPF offered mice the option of a high - fat «cafeteria»
diet or a mixture of chopped - up commercial chocolate bars alongside their
regular lab
chow, before carrying out a detailed analysis of the animals» activity and feeding behaviour.
(One control group received
regular rat
chow and water, and the other received a nonalcoholic liquid
diet equal in calories to the alcohol feedings.)
