Eat More Greens
Leafy green vegetables such as spinach, kale, collards, watercress, and romaine are not only full of nutrients but also very low in calories compared with other foods. "The average one cup of raw leafy greens clocks in under 25 calories with virtually no fat, sodium, or sugar," said Lisa Moskovitz, RD, CDN, at the New York Nutrition Group. "By filling up on plenty of yummy greens, you can keep your belly full on the fewest possible calories not to mention nourish your body with key nutrients including vitamin A, vitamin K, iron, and fiber. You can have more voluminous meals but lose weight at the same time."
