The study, conducted by researchers from the Autonomous University of Barcelona, fed mice either a standard or high-fat diet for a period of 10 weeks. Their size was monitored during that time, with the weight of those consuming a standard diet increasing by 27 per cent while the mice on the high-fat diet increased 72 per cent in size, making them obese.
The obese mice were then injected with the hormone while the others were given a placebo. All rodents were then fed their respective diets for a year with their weight monitored during that time.
Results showed that these weight of the obese mice stabilized as a result of the hormone injection and within a few weeks they were of equal size to their standard-diet counterparts. Their insulin sensitivity also increased within that time.
