How to Keep the Pounds Off

The key to losing weight is eating less. Exercise may be good for you, but it doesn’t really have much impact on weight. Right?

It is a question that plagues all who struggle with weight: Why do some of us manage to keep off lost pounds, while others regain them?

Now, a study of 14 participants from the “Biggest Loser” television show provides an answer: physical activity — and much more of it than public health guidelines suggest. On average, those who managed to maintain a significant weight loss had 80 minutes a day of moderate activity, like walking, or 35 minutes a day of vigorous exercise, like running.

….“The findings here are important,” said Rena Wing, a psychiatry professor at Brown University and a founder of the National Weight Control Registry, which includes more than 10,000 people. The food eaten “is the key determinant of initial weight loss. And physical activity is the key to maintenance,” she said.

Poof. Another piece of conventional wisdom about weight loss is now turned on its head. Maybe. Gotta replicate first, though. Damn scientists.

$500,000 MATCHING GIFT

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones: A special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of the huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
