The American Heart Association recommends that the amount of added sugar consumed in a day shouldn’t exceed 25 grams for women and 37.5 grams for men, but since the sweet stuff is in everything from bread to tomato sauce, most Americans aren’t adhering to those guidelines and they’re fatter for it. In a review of 68 clinical trials and studies, New Zealand researchers reported in the British Medical Journal that increasing sugar intake meant increasing body weight while reducing sugar meant reducing body weight. Additional research has shown that cutting back on the granular stuff is one of the fastest ways to lose weight.
If you just can’t shake those belly-bloating sugar cravings, try tyrosine—a building block of protein. It has been shown to prevent that yearning for the sweet stuff by encouraging the brain to release dopamine and another neurotransmitter, norepinephrine. In other words, eating more tyrosine (which can be found in eggs, spirulina, certain cheeses such as Parmesan, Gruyère, Swiss, and Romano, milk, sesame seeds, beef, and bacon) helps fend off those harmful sugar cravings that make your belly fat.
Your favorite childhood snack is good for your grown-up self, too. Because peanut butter is a great source of protein and healthy fats, it can curb hunger and keep you feeling full long after you're finished eating. Having small snacks during the day that include a lean protein such as peanut butter with complex carbs (like an apple or banana) can also help keep your metabolism running smoothly.
Think writing a grocery list before heading to the store is a waste of time? As it turns out, it may be the key to finally losing weight. A Journal of Nutrition Education and Behavior study of more than more than 1,300 people discovered that shoppers who regularly wrote grocery lists also purchased healthier foods and had lower BMI’s than those who didn’t put pen to paper before heading to the store. Researchers hypothesize that shopping lists keep us organized, which in turn helps us fend off diet-derailing impulse buys (hello, candy aisle). Before heading to the supermarket to stock up, spend a few minutes taking inventory of your kitchen, and then write a list. Be sure to organize it by category to prevent zigzagging all over the place; that ups the odds you’ll walk by—and purchase—tempting treats that could derail your weight loss success.
