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.

Your physician may use magnetic resonance imaging (MRI) to record detailed pictures of your fat tissue. They may also use CAT or CT scans to produce cross-sectional images of your body or other bioelectrical impedance machines to differentiate between fat tissues. Calipers are sometimes used to measure fat under muscle but are not considered to be an accurate tool.
The internal and external obliques, which I like to call "nature's girdle," are located at the sides of the rectus abdominis. They are the muscles you use when you bend sideways at the spine or twist at the waist. They also contract to compress the abdomen, so you should work them just as hard as you work the rectus abdominis. Adding a twist to crunches works, as well as dumbbell side bends, but be careful not to use any jerky motions, especially if you've had back problems.
We're not talking about extra pounds of stomach fat here. We're talking about the temporary abdominal distention that plagues most everyone from time to time. Michael Jensen, MD, an endocrinologist and obesity researcher at Mayo Clinic, says unless your stomach bloating is caused by a medical condition such as liver or heart disease, the only real cause is intestinal gas - not "water weight."
They may not be totally mainstream yet, but there's good reason to incorporate marine gems like nori, hijiki, wakame, arame, and kombu into your regular diet. "With omega-3 fatty acids not found in other plant foods, sea vegetables (or seaweed) are inflammation fighting powerhouses," says St.John. "Omega-3 fatty acids are potent inflammation-fighters, so sea vegetables can enhance your body's ability to suppress inflammation and may lead to a flatter belly." Note: Store-bought seaweed snacks can pack a lot of sodium (which can contribute to bloat), so be sure to scan nutrition labels before purchasing.
This is what's known as insulin resistance. Basically, when your body doesn't respond well to insulin, it actually makes more of the stuff, according to the National Institute of Diabetes and Digestive and Kidney Diseases. And that can lead to fat storage, especially around the middle of your body. That's where protein comes into play: A diet high in protein may protect you against insulin resistance, says Aronne.
