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.

Try the paleo diet to help you avoid processed foods. Back when cavemen still ruled the earth, they didn't have time to bake cupcakes or fry potato chips. The paleo diet (short for paleolithic) seeks to recreate the same diet that our early ancestors ate, claiming that our systems are not built for modern ingredients and cooking styles. You eat meat, vegetables, fruit, and other foods that would have been available back then, and avoid anything paleo people wouldn't have had.[12]
Add a cup of low-fat milk, a part-skim mozzarella stick, or a half cup of low-sodium cottage cheese to breakfast, and you may have a belly-busting win. While lots of research links calcium with lower body weights, results from a 2014 study suggest that calcium-containing foods may reduce waist circumference in those genetically predisposed to carrying weight in their midsection.
