Blackberries, blueberries, strawberries (and more varieties) are an ideal weight-loss food because they’re relatively low in calories, pack a nutrient-dense punch, and add tons of flavor to otherwise lackluster meals. “Loaded with fiber and antioxidants, these little fruits are great on cereal, yogurt, smoothies, salads, or alone as a snack,” Zeratsky adds. Fruit gets a bad rap when it comes to weight loss because of their natural sugar, but this actually helps relieve the monotony of a diet program. Berries satisfy your sugar cravings without destroying your progress because they’re filling, and can effectively curb your overal calorie intake by slowing digestion and the absorption of fructose.
Make sure that everything you're eating is whole — as in nothing processed or packaged. Since salt is a preservative, these are the foods that are highest in sodium — something to keep in mind when planning your meals. Plan on making sure that all items you choose are fresh. That means filling up on fresh fruits and veggies, whole grains, low-fat dairy, and lean protein.
Many variations of this eating style exist — ranging from fasting for a number of hours each day up to an entire 24-hour fasting period one or two times a week. “If you're trying to kick a habit like eating late into the night, then stopping eating earlier in the evening and fasting overnight could be beneficial for you,” says Hultin. “There are many types of intermittent fasting, so ensuring you pick one that works for you and your lifestyle is important.”
“Whether it’s an app or paper food logs, tracking what you eat will certainly be eye-opening. Almost everyone consumes more than they think. Write everything down as soon as you’re done eating so you don’t forget anything. The simple act of recording what you eat will make you eat less. When the calories are in your face, it makes you think twice!” — Martha McKittrick, RD, CDE
In an accompanying comment, Corby Martin and Kishore Gadde write that the study shows that "a slow and steady approach does not win the race, and the myth that rapid weight loss is associated with rapid weight regain is no more true than Aesop's fable." They cite a number of potential short-term advantages of very low calorie diets and note that these diets are now well formulated and provide adequate protein and essential micronutrients. They are "safe if used under expert supervision," the write.
