Fat Kids, Skinny Kids

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


If you take populations as a whole, you find that they become fatter as they become more developed. That’s because they have more money, their lifestyles are more sedentary, and they eat more processed food that’s high in fat and sugar.

But what about individuals? What explains why some kids are overweight and others aren’t? Sarah Kliff gives us a tutorial:

Studies have found that, of the many home-environment factors at play, maternal obesity is the best predictor of childhood obesity, even more so than low family income or less cognitive stimulation.

But more recent research, particularly a highly cited study in the American Journal of Clinical Nutrition, suggested that was more a question of genes than habits. The study, which followed 5,092 pairs of British twins ages 8 to 11, found that the most influence parents have on obesity is actually genetic, a factor of inheritance, rather than the environment. “Contrary to widespread assumptions about the influence of the family environment, living in the same home in childhood appears to confer little similarity in adult BMI [body mass index],” authors Jane Wardle, Susan Carnell, Claire Haworth and Robert Plomin write.

….“Although contemporary environments have made today’s children fatter than were children 20 years ago, the primary explanation for variations within the population, then and now, is genetic differences between individual children,” they write.

This hardly absolves parents from trying to instill good eating practices in their kids or the food industry from assaulting the airwaves with fat-laden crap. But it does suggest that maybe we should ease up on all the brickbats aimed at bad parenting. In many cases, the modern food industry is knocking on an open door.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
