How Many Extra Calories Add Up to Obesity for Kids?
Study finds overweight children consume more excess calories daily than previously thought
Dr. David Katz, director of the Yale Prevention Research Center, praised the new model, and said it clarifies energy intake levels needed to achieve public health goals.
"Importantly, given the rather large calorie excesses fueling childhood obesity, this model is a rebuttal to the food industry arguments that exercise alone can be the answer," said Katz, who is also editor of the journal Childhood Obesity.
"For our kids to achieve healthy weight, control of calories in, not just calories out, will have to be part of the formula," said Katz, who was not involved in the research.
But there's some good news in the new numbers, too. As doctors and parents have long suspected, some kids appear to be able to outgrow their extra pounds when they shoot up in height during puberty, though that feat may be easier for boys than girls, because boys gain more calorie-burning muscle during puberty than girls.
"If you haven't reached puberty and haven't yet reached that growth spurt, that might be the ideal time to institute a weight management intervention to harness the power of the growth to decrease fat mass and increase fat-free mass," said study author Hall.
