You know you're supposed to eat more protein to lose weight, but you might not know exactly why. Well, it actually has to do with how your body handles insulin. "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University.
While it's true that 75 percent of the salt most people eat comes from processed foods and restaurant meals, not all salts are created equal. Pure, unrefined salts like Himalayan and Celtic sea salt have a much lower sodium count than its refined counterparts. Use it when you cook, which not only brings out the natural flavors in your dish (making you more satisfied and less likely to overeat), but also ups your mineral intake. Because unlike refined salt, which is 99 percent sodium and chloride, unrefined varieties also include elements like magnesium and calcium. Now, that doesn't mean you should go overboard, but it does give you the go-ahead to add a little something-something to your next meal.
Intermittent fasting has blown up in the past year, but scientists are just starting to figure out how it can help you lose weight. In one study from the University of Illinois at Chicago, researchers compared obese people in a traditional weight loss group and fasting group. For the experiment, the calorie-restricted group simply reduced the amount of calories they ate by 25 percent each day. The fasting group, however, alternated days: they ate 25 percent of the calories they needed one day between 12 and 2 p.m., and then had feast days the next, where they ate 125 percent of their required calories.
