Canned tuna could be your solution to a flatter belly — and it'll only cost you around 80 cents a pop. "Canned tuna — as well as other fish — is an excellent source of omega-3 fatty acids," Taub-Dix days. "Besides promoting heart health, omega-3s help you ditch pounds by keeping you feeling satisfied while repairing and replenishing muscles." Win-win, much? Instead of making tuna salad with fatty mayo, try Greek yogurt instead. The mix makes the perfect filling for a healthy lettuce wrap or stuffed into an avocado half.
And maybe a new mattress, because it’s not just the amount of time you spend sleeping that keeps you lean, it’s also the quality of your sleep. Fat cells in your body produce a hormone called leptin that helps the body keep track of how much potential energy (i.e. fat) it has stored. But leptin is only produced during certain stages of sleep. Miss out on those stages because you’re not resting soundly enough, and you’ll disturb levels of the hormone, leaving your body with no real idea of its energy reserves. Consequently, you’ll end up storing calories rather than burning them.
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.
Thanks to the hormone estrogen, the female body likes to hold on to fat, too. A study in Obesity Reviews shows that women store fat more efficiently than men in an effort to prepare the body for pregnancy. But while it seems like women may have drawn the short-end of the stick, the stereotypical pear-shape is actually considered healthier than boasting a beer gut, because belly fat is a red flag when it comes to your health. “Visceral fat is associated with increased risk of diabetes, high blood pressure and metabolic syndrome,” says Harris-Pincus.
