A recent study published in PLoS ONE found that the Body Mass Index (BMI) substantially under-diagnoses obesity in the US, with 39% of Americans classified as overweight being actually obese. The researchers suggest using leptin levels in conjunction with BMI to provide a more accurate measure of adiposity.

The findings contradict previous research on obesity's impact on inflammatory bowel diseases. Further studies are needed to understand the association between body fat percentage and immune responses.
A study published in Nature Medicine reveals that a mutation in the Bdnf gene can lead to uncontrolled obesity due to the inability of neurons to pass along appetite-suppressing signals. The researchers found that stimulating expression of this gene may offer a novel strategy for treating obesity.
