Isiah: Will I get travelling expenses? pro essay discount code While BMI has long been considered the most reliable indicator of body fat, it doesn't consider muscle mass, so could incorrectly indicate obesity, said lead researcher Dr. Margaret Ashwell of the Oxford Brookes University, UK, in a separate study. In that research, Ashwell led a team of investigators who looked at 31 studies, finding that waist-to-height ratio predicted diseases such as type 2 diabetes, cardiovascular disease, high blood pressure, cancers, stroke and respiratory problems better than BMI. The report was presented last year at the 19th European Congress on Obesity in Lyon, France.
