Cutbacks in mandatory physical education at school has contributed
to an overall decline in children's physical activity levels.
When these programs are available, they often involve little
actual physical activity and do not focus on the fun aspects
of physical activity. Also see Importance
of Recess in School.

Sleep and Weight Management
little sleep may cause weight gain by way of two hormones. Firstly,
lack of sleep may decrease levels of leptin residing in fat cells.
Lowered Leptin levels can block feelings of satiety and encourage
eating more. Secondly, sleep depravation increases ghrelin in
the gastrointestinal tract, which stimulates appetite.
Sleep Deprivation and Obesity
"Sleep Deprivation can cause physiological distress,"
said Dr. Sateia, a former president of the American Academy of
Sleep Medicine. "This may include impairment in immune function
and in carbohydrate metabolism. There is some interesting work
suggesting that sleep deprivation may be associated with disturbances
in appetite regulation and conceivably contribute to obesity,"
Lack of sleep has been linked to obesity, depression, diabetes,
and cardiovascular disease. However, other factors may be responsible.
People who don't get enought sleep also tend to eat more fast
food which could account for longer term problems rather than
lack of sleep per se, reported Mindy Engle-Friedman of the City
University of New York at the annual meeting of the Asssociated
Professional Sleep Societies in Minneapolis in June 2007.

Caffeine & High Carb Diet
A high carbohydrate diet negates the metabolic effects of
caffeine, such as increased mobilization and oxidation of fatty
acids, during exercise.

The EEOC has found that obese workers earn 2.5% less than
their normal weight co-workers. This penalty is larger for female
workers (5-6% less) than male workers (1% less).
A study by Cornell University found that overweight women
earn an average of 7% less than their co-workers.
Research review by Mark Roehling, a professor in the Department
of Management, Western Michigan University found wages of mildly
obese white women were 5.9 percent lower than their normal weight
counterparts; morbidly obese white women were 24.1 percent lower.
In addition, the wages of mildly obese white and black men were
actually higher than their normal weight counterparts. Men only
suffered wage penalties at the very highest weight levels. Overweight
individuals were often stereotyped as socially handicapped, emotionally
impaired, and perceived as possessing negative personality traits.
It should be noted that employers may have to pay more in
health insurance for obese workers. Weight discrimination is
illegal in Washington DC.
