Document Summary
Obesity paradox misunderstand the biology of opimal weight throughout life cycle. This paradox assumes that being overweight/obese measured by bmi provides mortality advantage compared to being a normal weight. Obesity (bmi>30) is associated with higher all-cause mortality, overweight (bmi 25-29. 9) exhibits lowest mortality risk. Reports show that overweight and class i obese individuals have lower mortality than normal weight. Energy reserves are needed in imes of illness, increasing with age. Opimal bmi for lowest mortality is not a constant and it varies with age, ethnicity and disease. Bmi above normal in older people may be associated with beter funcional capacity and reduced physical and cogniive decline. Generated a broader approach to understanding possible addiional mechanisms involved. Chronic diseases and aging are associated with reducion in lean body mass, bone mineral density, nutriion and physical funcion (greater in those of lower weight) Increased weight may provide advantages in aging and disease: sparing lead body mass, reducing impact of inlammaion, favourable lipids.
