Avocados are rich in monounsaturated fatty acids, dietary fiber, potassium and phytochemicals. People who eat avocados tend to have lower BMI, body weight and waist circumference than people who skip this green superfood, per a study in Nutrition Journal. While avocados are higher in calories than other fruits and vegetables, their satisfying fat and fiber combo may help you slim down. Add some to your salad, sandwich or taco night for a burst of creaminess and flavor.
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.
Another weight-loss-friendly substitute to keep in mind is favoring salsa over ketchup. While ketchup typically has around 19 calories and 4 grams of sugar per tablespoon, fresh tomato salsa has about 5 calories per tablespoon, no added sugar, and is packed with nutritious veggies. Tomatoes, for example, are loaded with fat-blasting fiber and vitamin C, a deficiency of which Arizona State University researchers associated with increased body fat and larger waists. If you can handle spice, toss some jalapenos in your salsa to rev up your metabolism. For more on how you can switch your metabolism into overdrive, check out the best ways to boost your metabolism!
At least half your grains should be whole grains, such as whole wheat, oats, barley, or brown rice. Whole grains retain the bran and germ and thus all (or nearly all) of the nutrients and fiber of the grain. One sure way of finding whole grains is to look for a product labeled “100% whole wheat” or “100%" of some other whole grain. You can also look for a whole grain listed as the first ingredient, though there still may be lots of refined wheat in the product. Another option is to look for the voluntary “Whole Grain Stamp” from the Whole Grains Council. Or try this tip: Look for less than a 10-to-1 ratio of “total carbohydrates” to “fiber” on the nutrition label.
A new twist on an old favorite ― if your favorite recipe calls for frying fish or breaded chicken, try healthier variations using baking or grilling. Maybe even try a recipe that uses dry beans in place of higher-fat meats. Ask around or search the internet and magazines for recipes with fewer calories ― you might be surprised to find you have a new favorite dish!
Fresh, Frozen, or Canned Vegetables ― try something new. You may find that you love grilled vegetables or steamed vegetables with an herb you haven’t tried like rosemary. You can sauté (panfry) vegetables in a non-stick pan with a small amount of cooking spray. Or try frozen or canned vegetables for a quick side dish—just microwave and serve. When trying canned vegetables, look for vegetables without added salt, butter, or cream sauces. Commit to going to the produce department and trying a new vegetable each week.
In addition to dietary recommendations for the general population, there are many specific diets that have primarily been developed to promote better health in specific population groups, such as people with high blood pressure (as in low sodium diets or the more specific DASH diet), or people who are overweight or obese (in weight control diets). However, some of them may have more or less evidence for beneficial effects in normal people as well.
