Genes, Scans, and Furtive Fat

The Guardian reports that in vivo molecular imaging can shed new light on how and where the human body stores its fat. The article focuses on the work of Jimmy Bell,  head of molecular imaging at the
College ,
London , who has used MRI to show that even apparently slim people can carry loads of “internal fat.” According to the article:

Genes also play an enormous role. 'Our work so far has shown that you can take two men of the same age, with the same BMI [body mass index], and find one with five litres of fat within him and another with two litres,' said
Bell , who works at
Hospital , west
London . 'We've even scanned people who are underweight and found up to seven litres of fat inside them.'

In addition to generating images of where internal fat stores are located,
Bell ’s work also delves into the temporal and regional gene expression underlying different types of fat tissue processing.
