The Sun newspaper reported he is getting so big that his parents are frightened of him - and they claim the youngster throws vicious tantrums if they try to stop him from gorging on huge plates of ribs and rice. They claim that although they try to cut his meals, he has gained 21 pounds in the last year. (REUTERS) Lu Hao walks with his parents on a street in Foshan, Guangdong province. Ironically, the toddler was underweight when he was born, weighing in at 5.7 pounds, but he started putting on weight at 3 months old and has not stopped. (REUTERS) Dr. Ari Brown, a Texas-based pediatrician and author of the "Expecting 411" book series, told FoxNews.com that Lu Hao’s below-average birth weight may have contributed to his current weight.

Last year, his worried parents took him to see specialists at the Guangdong Children's Hospital, where doctors thought his weight gain could be due to a tumor or hormone disorder.
