The idea comes on the back of his team's discovery that the chemical 5-adenosine monophosphate, or 5-AMP, induces a state of torpor in mice, which do not usually hibernate. Lee says that a capsule or injection of 5-AMP could induce a similar state in humans, and the accompanying metabolic changes could help treat a range of conditions associated with obesity, such as diabetes, high blood pressure and eating disorders.

I'd say tiredness is linked to obesity ne way ie:eating to keep up energy or as comfort
