Despite how healthy you think your late night snack is, it can still have unintended consequences.

Late dinner? Too much Netflix and chilling—and snacking—before bed?

We’ve all heard that nighttime noshing is a bad idea. In part because it can wreck your sleep and, more disconcertingly, because it can make you gain weight. And sure, if you’re scarfing down potato chips or ice cream in addition to your regular meals, the pounds will probably pile on. But what if you’re accounting for those nighttime calories? Say, you have your usual dinner but at 10 p.m. instead of 7 p.m. or you save up to splurge on some popcorn while watching a movie.

If you’re not actually eating more—just eating later—will you still gain weight?

The answer is probably yes—so make sure to incorporate the 7 Essential Metabolism Boosters into your routine to help keep your potential weight gain to a minimum. Experts have uncovered a lot about the relationship between sleep and weight in recent years, and while there’s still a lot to learn, an increasing amount of evidence suggests that your body knows when it’s supposed to be awake and getting food and when it’s supposed to be asleep and not eating anything. And feeding it at the wrong time could spell trouble on the scale.

“The enzymes involved in fatty acid oxidation, they’re highly circadian. They know when they’re supposed to be metabolizing glucose,” says Kristen Eckel-Mahan, PhD, who studies sleep and metabolism at the University of Texas Health Science Center at Houston.

So when you eat at an unexpected time—say, 11:30 at night, when you should probably be powering down for sleep—metabolic organs like your liver seem to get confused. They’re not prepared to deal with an influx of nutrients at that time, so they process those nutrients less efficiently—and that can spell problems for your insulin and blood sugar levels—which prompts your body to store more fat.


In fact, findings show that people who regularly eat later—like night-shift workers and those with night eating syndrome—when a person eats more than 25 percent of their food after dinner—tend to have higher waist circumferences and BMIs when compared with people who eat on a more conventional schedule. And even healthy women who eat their meals later metabolize carbohydrates at a slower rate, have a lower glucose tolerance, and burn fewer calories while at rest, compared with those who eat earlier, according to a recent study published in the International Journal of Obesity.

The fix? For starters, skip the late-night eating. It’s no secret that we tend to make less-healthy food choices at night—midnight milk and cookies, anyone?—but even a clean, well-planned snack too late in the evening can throw a wrench in your metabolic machine. So aim to cut off food at least two hours before bedtime, recommends Caroline Cederquist, MD, a physician specializing in nutrition and metabolism and the founder of BistroMD—and add the 7 Yoga Poses That Shed Pounds to your workout plan.

And for those days when you know dinner is going to be late—the weekends, crazy workdays, vacations, business trips—at least make your evening meal lighter. Most of us tend to eat smaller breakfasts and lunches and then larger dinners—but striking more of a balance can help. What that looks like—Cederquist recommends about 4 ounces of protein, making half of your plate veggies, and having a serving of starch or fruit at each meal.
