Major link in brain-obesity puzzle found

...the use of energy from food. It even moderated the impact of a high-fat diet on body weight. The experiments were performed in mice, including two types of mice that the team altered genetically so that they only expressed a unique form of the SH2B1 protein in their brain cells. The protein occurs elsew...
