Extreme obesity is affecting more children in the United States than ever before.
That's the conclusion of a new study looking at children in southern California. As many as one in three children in black and latino communities in that area are now said to be overweight.
Extensive studies in the United States show that more than 7% of boys and 5% of girls are classified as extremely obese.
The problem is worse in some ethnic groups, particularly black teenage girls and Hispanic boys.
A health and wellness coach in Los Angeles, Tammy Foy, says that without dietary changes, these children's lives could be shortened by 10 to 20 years.
