what a healthy diet looks like

LOSING WEIGHT IS NO EASY TASK, WHICH HELPS EXPLAIN WHY THE U.S. weight-loss market is a $ 72 billion industry. Dropping pounds quickly or through dramatic short-term approaches is often not the best idea, yet Americans spend billions of dollars each year going on coordinated diet programs, undergoing bariatric surgery, using apps that track their every calorie and step, and even embracing “fad” diets (Paleo or keto, anyone?). And for all that, the weighty truth is that more than 70% of U.S. adults remain either overweight or obese. On the surface, weight loss should be simple: cut back on calories and ramp up on exercise, and the pounds should fly—and stay—off. But more complicated than that. “Obesity is a real disease, with real physiological consequences: when you gain weight, the nerves…

why your diet isn’t working (and what to do about it)

LIKE MOST PEOPLE, KEVIN HALL used to think the reason people get fat is simple. “Why don’t they just eat less and exercise more?” he remembers thinking. Trained as a physicist, he had always thought the calories-in-vs.-calories-burned equation for weight loss made sense. But then his own research—and the contestants on a smash reality-TV show—proved him wrong. Hall, a scientist at the National Institutes of Health (NIH), started watching The Biggest Loser several years ago on the recommendation of a friend. “I saw these folks stepping on scales, and they lost 20 pounds in a week,” he says. On the one hand, it tracked with widespread beliefs about weight loss: the workouts were punishing and the diets restrictive, so it stood to reason that the men and women on the show would…

5 secrets to lasting loss

They eat breakfast. » People in the NWCR have lost at least 30 pounds and kept it off for at least a year. One habit they share: they have a morning meal every day.

They move a lot after losing weight, exercising for about an hour a day on average. A common exercise is walking.

what is intermittent fasting and is it actually good for you?

LASTING WEIGHT LOSS. PROTECTION FROM DIABETES, heart disease and cancer. Improved brain health. Enhanced physical fitness. It seems as if every week, researchers turn up a new benefit associated with intermittent fasting: eating schedules that incorporate regular periods of low or no food consumption. By eating normally several days a week and eating much less on the others, a person may be able to shift his or her body’s cellular and metabolic processes in ways that promote optimal health. And experts say that while many blanks still need to be filled in, some of the positive health effects of intermittent fasting are no longer in doubt. “There continues to be good evidence that intermittent fasting is producing weight-loss benefits, and we also have some evidence that these diets can reduce inflammation, they…

fads: the good, the bad, the ridiculous

1810–1820s: Vinegar and Water Diet » Romantic-era poet Lord Byron believed that obesity causes lethargy and stupidity, so he hopped onto the Vinegar and Water Diet, according to the book Calories & Corsets. It’s as appetizing as it sounds: water mixed with apple-cider vinegar. And to the present day, some people claim this method burns fat. 1925: Cigarette Diet » The roaring ’20s introduced its own dubious diet plan: smoke your way slim. A Lucky Strike cigarette ad campaign advised to “reach for a Lucky instead of a sweet” and “to keep a slender figure … reach for a Lucky.” It’s hard to imagine any advice worse than that. 1950s: Cabbage-Soup Diet » This plan promised you could lose 10 pounds in seven days by living largely on—you guessed it—cabbage soup. (On certain days you…

why you should stop counting calories

KERI RABE, AN ELEMENTARY-SCHOOL LIBRARIAN IN Austin, Texas, used to be a hard-core calorie counter. Each day for a year, she logged everything she ate. She would only eat favorites like twice-baked potatoes and tater-tot casseroles if she made them with low-fat dairy, believing dietary fat would make her fat. She calculated every last calorie. “I thought for sure that was the only way to consistently lose weight,” she says. “I thought I’d have to do it for the rest of my life.” By one measure, it worked; Rabe lost 10 pounds that year. But even though she met her goal, she was frustrated. She hated doing math before and after every meal, and even though she got away with eating low-quality food while losing weight, she still didn’t feel good—and…
