1 in 3 Americans is obese, twice as many 3 decades ago
15 percent of children are overweight or obese, a three fold jump from 1980
Being overweight is associated with 400,000 American deaths per year.
Being overweight increase the risk of heart disease, type 2 diabetes,
colon cancer, breast cancer, and endometrial cancer.
The Center For Disease Control reports that adult women are eating 335 more calories per day then they did in 1971. Adult men are eating an extra 168 calories a day.
1 pound of fat is about 3500 calories. An excess of 250 calories a day will
put on 26 pounds a year.
Being overweight or obese is a matter of taking in more calories then are used.
Most overweight and obese people are out of caloric balance,
but only by a tiny amount of calories per day. A 250 calorie deficit per day
will subtract 26 pounds a year.
