Preventing diabetes, biological passport for athletes and more from the Lancet

Low-dose combination therapy with rosiglitazone and metformin was highly effective in prevention of type 2 diabetes in patients with impaired glucose tolerance, with little effect on the clinically relevant adverse events of these two drugs.

Preventing type 2 diabetes with low-dose combinations: Lifestyle interventions aimed at reducing bodyweight, and use of metformin, thiazolidinediones, acarbose, and orlistat, reduce the risk of diabetes by 25—60% over 3—6 years

The biological passport and doping in athletics: A biological passport monitors an athlete's blood and body chemistry values over time to assess whether there has been a deviation from an established baseline, thus indirectly detecting illegal manipulation.

A long look at obesity: Even with their primitive understanding of nutrition, our neolithic forebears somehow made the “right choices”, thriving on a wholesome diet of nuts, seeds, and fruits with the occasional piece of meat. And what is more, their rare intake of animal protein could only have been obtained through vigorous exercise, which they would, of course, indulge in every day.
