When you have your meals may be just as vital as what’s in them, new science shows. Here’s how to work the timing for maximum benefits.
Turn over a new leaf
Kale is branching out. Newer varieties like Siberian and Chinese are leafier, flatter, and more tender than traditional Tuscan and work well in salads. “They’re similar to arugula, with a little crunch and sweetness,” says Nicholas Roberson, the corporate chef for Copper Branch, a plant-based restaurant chain in New York City. “Toss them with carrots, red cabbage, croutons, and lemon-garlic aioli, or combine them with avocado, strawberries, vegan feta, chopped almonds, and lemon–poppy seed dressing for a mix of textures and flavors,” Nicholas says.
5 pm, when the day begins to wind down, your body does the opposite – cranking up to be at its calorie-burning peak, according to a recent study. “We discovered that you naturally burn about 10 per cent more calories in the late afternoon than you do later at night,” says Kirsi-Marja Zitting, an associate neuroscientist at Brigham and Women’s Hospital in Boston, an instructor at Harvard Eat for your body clock Medical School, and the lead author of the study, which was published in Current Biology. That’s about 130 calories that your body is torching without any extra effort on your part.
CLOCKWORK Eat breakfast, lunch, and dinner at the same time every day to maintain a healthy weight.
Although researchers don’t know why our calorie expenditure revs up in the late afternoon, they suspect that metabolism ebbs and flows according to our circadian rhythms. That means that at night, when we’re asleep, our systems are expending less energy, so our metabolic rate slows. Eat in those wee hours, as night shift workers do, and your body isn’t able to burn off the calories, which could eventually lead to weight gain, Kirsi-Marja says. During the day, when we’re naturally active and busy, our metabolism rises, until it crests around 5pm.
“Previous research has shown that hunger spikes in the afternoon as well,” Kirsi-Marja says. “Since that’s also when we’re burning the most calories, it makes sense that we’re hungriest then too. Our bodies may be tuned to a late-in-the-day rhythm.”
Syncing our diets to our internal clocks can have significant health benefits. Here are the most effective methods to help you do that.
Find your flow
For general well-being, the most important thing is to maintain a regular schedule, Kirsi-Marja says. “Wake up and go to bed around the same time every day,” she advises. “And have breakfast, lunch, and dinner at about the same hours as well.” Your body is primed to do things at certain times. Throw its agenda out of whack, and your sleep, health, and weight can suffer.
Navigate the extremes
Of course, there will be times when you can’t maintain your routine. Let’s say you get home at 10pm after a crazy day. Avoid eating a big meal then because your body is in slowdown mode and is less likely to burn it off, Kirsi-Marja says. Instead, have a healthy dinner earlier, before you leave work.
Similarly, on days when you need to get up at the crack of dawn, skip a big breakfast first thing. “Your body burns the fewest calories at 4am,” she adds. If you eat before six, your system will store more of what you consume.
Choose your foods wisely
It may be beneficial to eat your carbs early in the day and foods that are higher in fat at night. “Our research found that you are more prone to burn carbohydrates in the morning and lipids or fats in the evening,” Kirsi-Marja says. “The difference was small, but it was significant.” While she cautions that the finding is preliminary and that she and her team plan to do more research to see if it holds up, having a healthy carb-oriented breakfast (like a bowl of oatmeal) and foods that contain good-for-you fats (like avocado, cheese, and salmon) for dinner may be a smart idea.
