Conventional Wisdom on Obesity Risk Factor Questioned (BBC News / Lancet Diabetes and Endocrinology / NHS Choices)

Summary

A large-scale analysis of medical records for nearly two million British people over up to two decades, by Oxon Epidemiology and the London School of Hygiene and Tropical Medicine, has discovered surprising relationships between obesity / body mass index (BMI) and dementia risk.

The evidence indicates that underweight people are most at risk of developing dementia. Underweight people have a 39% higher risk of dementia than people with what is considered to be a healthy weight. People who are overweight, by contrast, appear to benefit from an 18% reduction in dementia risk, and this seemingly rises to 24% for those considered obese.

The true spirit of science involves continuously attempting to disprove conventionally held models, and exploring the limits of our existing understanding; accordingly this research should be applauded (rather than viewed as an inconvenience).
