Go ahead. Pop up a bowl. Sans the butter and salt, popcorn is a real gut whittler. Why? Because popcorn is a whole grain—and a study revealed that people who ate lots of whole grains had smaller middles compared with folks who ate mostly refined grains. So while you're waiting for yours to pop, clear all the white rice, pasta, and bread out of your cupboards. (Related: Give your popcorn some low-guilt flavor with these tips.)
There's a reason poop is being talked about so much these days — when there's problems with it, it's an easy tip-off that something's not quite right with your insides. But most people don't realize that constipation leads to weight gain, so they never consider it to be the culprit behind those tighter-fitting jeans. "If you're constantly constipated, then it likely means you're on a poor diet that can also make you overweight, or you lack important nutrients that help keep things moving," explains Vincent Pedre, M.D., author of Happy Gut. Besides drinking plenty of water throughout the day (don't guzzle it down in one meal, as that can slow down digestion), Pedre says to eat plenty of fiber-rich legumes like yellow beans and lentils to keep your stool moving. And don't worry about bloat or gas — soaking beans overnight nixes that problem.
Stop treating your kitchen like an all-night diner and you’ll stop seeing those unwanted pounds piling onto your frame, too. The results of a study published in Cell Metabolism found that mice who only had access to food during an eight-hour period stayed slim over the course of the study, while those who ate the same number of calories over a 16-hour period gained significantly more weight, particularly around their middle. When you’re finished with dinner at night, shut the fridge and don’t look back until morning — your belly will thank you. When you do head back to the kitchen in the A.M., make sure the 40 Things Healthy Cooks Always Have in Their Kitchen are there waiting for you.
To banish stubborn belly fat, you have to ramp up your workouts. In a study published in the journal Medicine and Science in Sports and Exercise, people who completed a high-intensity workout regimen lost more belly fat than those who followed a low-intensity plan. (In fact, the low-intensity exercises experienced no significant changes at all.) "You need to exercise at full intensity because the end goal is to burn more calories, and high intensity exercise does just that," says Natalie Jill, a San Diego, Calif.-based certified personal trainer. High intensity workouts mean you're going all out for as long as you can. If this sounds intimidating, think of it this way: you'll burn more calories in less time.
2. Sweep: Start with basic abs tuck (standing crunch). For that you have to lift one knee using the abs, and bend the other knee to sit slightly on the ground. Bring the rib cage to the bellybutton so that the spine is in C-curve position. Simultaneously, squeeze the oblique on one side to crunch while reaching down for the opposite foot. Do 10 repetitions for each side, then do 10 again (total of 20, alternating after 10).
“Include lots of nutrient-rich vegetables, a source of protein and some healthy, unprocessed carbs,” says Belalij. “Start with leafy greens such as spinach, kale and collard greens, then add carrots, broccoli and peas. Lean meats, including turkey and chicken, are ideal as they are lower in fat and therefore calories, or, if you are vegetarian/vegan, add in tofu or a handful of nuts such as pine, cashew or almonds and a sprinkling of seeds (sunflower, sesame, pumpkin). When it comes to carbohydrates, rice, quinoa and potatoes are perfect.”
