I know everyone believes obesity is as simple as putting down the fork, but that's not true. Autoimmune diseases, Thyroid diseases and tumors, sleep apnea, long term prednisone use, smoking cessation and mental illnesses can all cause obesity. So these are medical conditions which should be covered by Medicare or Medicaid. Obesity costs this country far more in future problems than treatment ever would in the strokes, heart attacks, Diabetes care, mobility care and rehabilitation required down the road. How can you treat these causes of obesity (A 2006 review identified ten other possible contributors to the recent increase of obesity: (1) insufficient sleep, (2) endocrine disruptors (environmental pollutants that interfere with lipid metabolism), (3) decreased variability in ambient temperature, (4) decreased rates of smoking, because smoking suppresses appetite, (5) increased use of medications that can cause weight gain (e.g., atypical antipsychotics), (6) proportional increases in ethnic and age groups that tend to be heavier, (7) pregnancy at a later age (which may cause susceptibility to obesity in children), (8) epigenetic risk factors passed on generationally, (9) natural selection for higher BMI, and (10) assortative mating leading to increased concentration of obesity risk factors) but not others. Treatment will reduce future costs.
