Instead of ditching carbs or going low-fat, try a diet that's rich in veggies, beans, and legumes to increase your metabolism — and keep your blood sugar from spiking. "Many people think weight is all about calories in, calories out, but quality also matters," says Aunna Pourang, M.D. "[In a 2012 study], low-carb diets showed the most increase in metabolism, but also showed an increase in the stress hormone cortisol. This is why scientists concluded that the low-glycemic diet worked the best."
Sleep, sleep, sleep: Getting poor sleep impacts our hunger hormones, D’Ambrosio says. Studies have also found that less sleep was associated with a higher BMI. “Less sleep increases our ghrelin – our hunger hormone – and decreases our leptin – which helps us feel full,” she explains. “If you are looking to burn calories more efficiently and moderate your consumption, be sure to get enough sleep.”
If you're cutting calories to lose weight, add 200-300 to your daily intake once in a while, says Amanda Bonfiglio Cunningham, a senior Yoga Medicine instructor. "The body will get used to a calorie deficit diet, adjusting by slowing the metabolic rate. By allowing yourself a day of indulgence (not overindulgence!), you're creating a healthy balance," she explains. "The extra calories raise leptin production, a hormone that regulates appetite and energy. This rise triggers thermogenesis, the body's natural tendency to create heat, which results in burning calories." Pass the dessert menu!
Bring on the funny cat videos — they're good for your health, according to researchers. No, you won't get the same calorie-burning results as you get from your spin class, but laughing does give your metabolism a small boost. Astudy published in the International Journal of Obesity found that genuine laughter increased both energy expenditure and heart rate by 10-20 percent above resting values. Another study found that watching cat videos in particular can boost your energy level. Guess you know what you're watching on the treadmill from now on.
It’s like butter that grows on trees. But instead of the cholesterol, trans fats, and saturated fats in real butter, avocado contains metabolism-enhancing monounsaturated fat. And that’s not all. Each creamy fruit is also packed with fiber and free-radical-killing antioxidants. Free radicals are destructive rogue oxygen molecules—natural byproducts of metabolism—that trigger various chain reactions in the body that destroy cells and DNA, causing all kinds of health problems. Antioxidants in fresh fruits and vegetables can help neutralize some free radicals, but they can’t reach the mitochondria—the base camp for the free radical army—and that’s a problem. When your mitochondria aren’t working properly, your metabolism runs less efficiently. Enter: Avocado. A 2015 study found that monounsaturated-rich oil pressed from the fruit can help mitochondria become more resilient. Researchers say the results jive with low-disease rates in Mediterranean countries where olive oil—nutritionally similar to the avocado—is a diet staple.
