On top of their energy-revving carb, health-promoting antioxidant, and immunity-fostering vitamin C content, the magic of apples also comes from a different source: their fiber. What’s so special about this macronutrient? Besides helping us to stay “regular,” dietary fiber is also a powerful hunger zapper. By filling you up, slowing the rate at which you digest the rest of your food, and keeping your blood sugar levels stable—which maintains more consistent energy levels—fiber-filled fare keeps your hunger pangs from creeping up as often, which can significantly aid weight loss efforts.
As an added bonus, certain fibers can cling to dietary toxins, including cholesterol, and help eliminate them from your body. The result? A lower risk of heart disease and a longer life! Although immensely beneficial, apples aren’t the only way you can improve regularity and satiety to help blast fat. In fact, we’ve found a number of unsung superfoods that pack even more of this belly-flattening nutrient than an apple.
To compare apples to apples, we evened the playing field by keeping each food to a standard, single serving size. Below, you’ll find some of the best sources of dietary fiber, ranked in order from the least nutrient-dense to the most potent. Next time you’re at the grocery store, stock up on these items to help you keep your body goals on track. And just because these foods are high in fiber, it doesn’t mean they’re the only fiber-filled foods that are good for you. These 15 Prebiotic Foods For Your Probiotic Efforts don’t boast sky-high fiber levels, but the type they do have—prebiotic, soluble fibers—has been proven to aid in improving gut health, which has been linked to making weight loss even easier.

<strong>Fiber Payout: 4.5 grams per medium Russet potato baked, flesh and skin</strong>

Thick, coarse, steel cut oats are the least processed form of oats—made of whole oat groats roughly chopped into small pieces. That means they’re the closest thing to a whole grain, which also leaves this particular oat with the highest protein and fiber count of the bunch.
