Being too thin can be deadlier than being overweight, Danish study reveals
"It is possible to be "fat but fit," new research being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria (September 15-19) suggests. The study of tens of thousands of people in Denmark found that those with a BMI in the overweight category - and even some of those living with obesity - were no more likely to die during the five years of follow-up than those with a BMI of 22.5-<25.0 kg/m 2, which is at the top end of the normal weight range."
""Both underweight and obesity are major global health challenges," says Sigrid Bjerge Gribsholt, of the Steno Diabetes Center Aarhus, Aarhus University Hospital, Aarhus, Denmark, who led the research. "Obesity may disrupt the body's metabolism, weaken the immune system and lead to diseases like type 2 diabetes, cardiovascular diseases and up to 15 different cancers, while underweight is tied to malnutrition, weakened immunity and nutrient deficiencies."
Health data from 85,761 Danish adults (81.4% female, median baseline age 66.4 years) indicate five-year mortality was similar for individuals with BMI in the overweight range and for some people with obesity compared with BMI 22.5–<25.0 kg/m2. Higher mortality occurred among those with BMI in the middle and lower parts of the normal range (18.5–<22.5 kg/m2) and among underweight individuals. Obesity associates with metabolic disruption, immune weakening, type 2 diabetes, cardiovascular disease and many cancers. Underweight associates with malnutrition, weakened immunity and nutrient deficiencies. Historical lowest-mortality BMI estimates near 20–25 may be shifting upward.
