Watermelon
Watermelon is a great post-workout choice, easy to digest because it's relatively low in fiber. It also provides potassium and antioxidants like vitamin C. One cup of diced watermelon is only about 46 calories, and it's full of water, which helps keep you full.
Apple
A large apple has about 148 calories and 5 grams of fiber. The soluble fiber in apple flesh slows down the rate at which food leaves the stomach, which helps keep you fuller longer after eating. Apples also contain polyphenols, which are thought to help prevent belly fat accumulation.
Tomato
A medium red tomato has 22 calories, 1 gram of protein, and nearly 2 grams of fiber. Despite its small fiber and protein content, tomatoes are virtually fat-free and packed with potassium, vitamin K, and vitamin C. Plus, tomatoes are 95 percent water, so you'll get the hydration you need.
Oatmeal
One cup of cooked oats has about 134 calories, 5 grams of protein, and 5 grams of fiber. They are an excellent source of zinc, magnesium, and phosphorus. Cooked oats expand in volume and promote feelings of fullness.
Consider topping your plain oats with fresh berries, spices, and unsweetened plant milk to keep this food low in calories.
Japanese Soybeans
Edamame is an excellent source of protein, fiber, and potassium. Eating Edamame in the pod helps slow down the absorption of food, enhancing hunger signals. Instead of salt, add spices and herbs to your Edamame for a rich flavor.
