Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
Good news, wine drinkers. Thanks to resveratrol, an antioxidant found in grape skin, drinking red wine in moderation can be part of a healthy diet. Some studies suggest that people who drink wine have smaller waists and less abdominal fat than those who drink mainly liquor. And having one glass of red wine can increase your body's calorie burn for up to 90 minutes afterwards. The antioxidants in wine might even help your body prevent cancer and improve heart health. Just be sure to stick to no more than a glass a day—the calories can add up fast.
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.

In general, healthy eating ingredients are found around the outer edges of most grocery stores, while the center aisles are filled with processed and packaged foods that aren’t good for you. Shop the perimeter of the store for most of your groceries (fresh fruits and vegetables, fish and poultry, whole grain breads and dairy products), add a few things from the freezer section (frozen fruits and vegetables), and visit the aisles for spices, oils, and whole grains (like rolled oats, brown rice, whole wheat pasta).
For a 2,000-calorie daily diet, aim for 2½ cups of vegetables and 2 cups of fruit a day. If you consume more calories, aim for more produce; if you consume fewer calories, you can eat less. Include green, orange, red, blue/purple, and yellow vegetables and fruits. In addition to the fiber, the nutrients and phytochemicals in these foods may help protect against certain types of cancer and other diseases. Legumes, rich in fiber, can count as vegetables (though they have more calories than most vegetables). For more fiber, choose whole fruits over juice.
OK, a bit of buzzkill news here: That rumor that chili peppers will crank up your metabolism as some kind of "fat-burning food" is a myth. Sure, they might have a modest effect on your metabolism, but nothing to produce any major effects. So, why should you still include chili peppers in your diet? Because getting creative with spices can help you lay off salt, plus, flavorful meals are always more satisfying.
