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.

You know that friend who casually chats about the healthy meals she whips up for her fam like it's NBD? She's planning ahead, and you should be, too. "When you plan an entire week of dinner in advance, you're way less likely to go off course and indulge in foods that aren't good for you," says Salzman. (Her weekly dinner planner is a favorite for Elizabeth Berkley when she needs food-spo.) Science backs her up, as those who spend more time prepping food at home eat at least eight servings of fruit and 13 servings of veggies each week, while those who don't tend to eat only six servings of fruit and just under 11 servings of vegetables. So get into a routine and, after weekly grocery shopping, kick the kids out for playtime with Dad so you can knock out as much work ahead of time as possible — cleaning and slicing veggies, portioning out chicken breasts for each meal, etc. Come dinnertime, there'll be barely any work before food is on the table.


If you're on a paleo diet, be careful: There's a chance you might getting too much protein, according to Melina Jampolis, M.D., author of The Doctor On Demand Diet. The average woman only needs around 46 grams per day, and a diet high in meat and meat products could cause excess protein to be stored as belly fat. Plus, too much meat can cause problems with inflammation and digestion due to all the hormones and antibiotics it contains.
Which means, sadly, the more glasses of rose and chocolate-coated pretzels you eat, the longer it will take to reach your flatter belly goals. “When you digest large amounts of calories, your body allocates some of these to functional systems which work to keep you alive (think the brain, muscles and organs),” says Belalij. “It also uses it to fill up energy stores. Any excess is then stored in fat cells around the body – typically being those of the belly.”
