Fat mass and obesity-associated protein, also known as alpha-ketoglutarate-dependent dioxygenase FTO, is an enzyme that in humans is encoded by the FTO gene located on chromosome 16. As one homolog in the AlkB family proteins, it is the first messenger RNA (mRNA) demethylase that has been identified. [ 5 ]
Set point theory does not on its own explain why body mass index for humans, measured as a proxy for fat, tends to change with increasing age or why obesity levels in a population vary depending on socioeconomic or environmental factors (or why weight tends to change for an individual when socioeconomic status and environment change). [4]
Preclinical obesity refers to excess body fat without current health issues but with increased risks of conditions like type 2 diabetes, heart disease, and certain cancers. Early interventions can ...
One study found that 80% of the offspring of two obese parents were obese, in contrast to less than 10% of the offspring of two parents who were of normal weight. [ 30 ] The thrifty gene hypothesis postulates that due to dietary scarcity during human evolution people are prone to obesity.
Pathophysiology of obesity is the study of disordered physiological processes that cause, result from, or are otherwise associated with obesity. A number of possible pathophysiological mechanisms have been identified which may contribute in the development and maintenance of obesity.
The term "infectobesity" refers to the hypothesis that obesity in humans can be caused by pathogenic organisms, and the emerging field of medical research that studies the relationship between pathogens and weight gain. The term was coined in 2001 by Dr. Nikhil V. Dhurandhar, at the Pennington Biomedical Research Center.
For years, medical experts have defined obesity primarily based on body mass index, which measures stored fat by calculating height and weight, to determine a person’s health risks. Major public ...
Osteoarthritis and obesity are closely linked. Obesity is one of the most important preventable factors for the development of osteoarthritis. Originally, the relationship between osteoarthritis and obesity was considered to be exclusively biomechanically based, according to which the excess weight caused the joint to become worn down more quickly.
