Diets to promote weight loss are divided into four categories: low-fat, low-carbohydrate, low-calorie, and very low calorie. A meta-analysis of six randomized controlled trials found no difference between the main diet types (low calorie, low carbohydrate, and low fat), with a 2–4 kilogram weight loss in all studies. At two years, all of the diets in the studies that reduced calories caused equal weight loss regardless of whether changes in fat or carbohydrate consumption were emphasized.
Hello, hydration. Watermelon, which gets its pretty color from the antioxidant lycopene, is a juicy, delicious way to make sure you’re staying hydrated—a key factor in weight loss for various reasons. When you’re drinking enough water, all your systems (including your metabolism) are better able to work at their maximum capacity, Shawn Talbott, Ph.D., a nutritional biochemist, told SELF in a previous article. Plus, proper hydration prevents you from confusing thirst for hunger, which can lead you to overeat throughout the day. And don’t buy into the hype about watermelon being a calorie bomb—1 cup only contains 46 calories.
These tiny fish are the unsung stars of the sea. With 23 grams of protein per can and a truckload of omega-3 and omega-6 fatty acids, they're an easy way to load up on nutrients. They're also low in mercury and high in calcium, making them a smart fish pick for pregnant women. If the flavor doesn't appeal to you, soak them in milk for an hour to help cut down on the fishiness.
Fresh, Frozen, or Canned Fruits ― don’t think just apples or bananas. All fresh, frozen, or canned fruits are great choices. Be sure to try some “exotic” fruits, too. How about a mango? Or a juicy pineapple or kiwi fruit! When your favorite fresh fruits aren’t in season, try a frozen, canned, or dried variety of a fresh fruit you enjoy. One caution about canned fruits is that they may contain added sugars or syrups. Be sure and choose canned varieties of fruit packed in water or in their own juice.
Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed monounsaturated-rich oils (like high-oleic canola oil or avocado oil) with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of the monounsaturated-rich oil daily lost nearly two percent of their belly fat in just one month.
Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
Here’s more reason to add avocado to everything. “Most of the carbohydrate content in avocados comes from fiber (1/3 of an avocado provides 11 percent of our daily fiber needs), and it also contains monounsaturated fat, which is known as a ‘good’ fat and [is] important for heart health,” says Zigler. Together, the healthy fats and fiber will keep you full to avoid mindless munching throughout the day.
Fat. Not all fat is the same. While bad fats can wreck your diet and increase your risk of certain diseases, good fats protect your brain and heart. In fact, healthy fats—such as omega-3s—are vital to your physical and emotional health. Including more healthy fat in your diet can help improve your mood, boost your well-being, and even trim your waistline. Learn more »
To set yourself up for success, try to keep things simple. Eating a healthier diet doesn’t have to be complicated. Instead of being overly concerned with counting calories, for example, think of your diet in terms of color, variety, and freshness. Focus on avoiding packaged and processed foods and opting for more fresh ingredients whenever possible.
