Because the amount of atmospheric carbon is well known and conservation of matter requires a balanced global carbon budget, this previously unaccounted for source of carbon to the atmosphere implies the existence of an additional continental carbon sink such as higher rates of biomass accrual in forests.
(World Cancer Research Fund/American Institute for Cancer Research (2007) Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective. AICR: Washington, DC). AICR/WCRF was the first organization to note that, after smoking, obesity is the most important preventable cause of cancer. While obesity is clearly linked to risk for developing many forms of cancer, the deleterious impact of obesity on prognosis has proven even more compelling in several studies.
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health. It is defined by body mass index (BMI) and further evaluated in terms of fat distribution via the waistâhip ratio and total cardiovascular risk factors.besity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications, or psychiatric illness.
