Nuts are high in protein, fiber and essential nutrients such as folic acid, potassium, magnesium, selenium and healthy monounsaturated fatty acids. Nuts, Particularly walnuts and almonds, have been shown in numerous studies to help prevent heart disease. A one-ounce serving of nuts either alone or combined with a small box of raisins, is an excellent way to boost your energy level and satisfy your appetite for many hours.Popcorn is a great high fiber, low calorie, low fat snack that's easy to make anywhere. The hot-air popcorn-popper ensures a virtually fat-free, high fiber snack; however, the non or low fat microwaveable varieties are also great, as long as you check to see that the butter or fat content is not too high. Popcorn can be mixed with peanuts, raisins, apple slices and other fruits for variety. You can even bake your popcorn with cinnamon, peanut butter, raisins, ftuit, Pannesan cheese and even garlic.A plastic baggie of your favorite dry high fiber, whole grain cereal, makes an excellent transportable nutritious snack to take with you anywhere. The addition of some dried ftuit to your travel cereal pack can add flavor and nutrition to your weight control snack. Even the varieties of cereals that are lightly sweetened are great diet snacks provided they're high fiber, whole grain, low sugar and low fat cereals. Check the ingredients label to make sure that there are no more than 1.5 grams of total fat and no more than 8 grams of sugar. Also make sure the cereal has at least 5 grams or more of dietary fiber. There's no need to check the amount of carbohydrates in thecereal, since as we've seen in the section on carbs, counting carbs is bogus. It has nothing whatsoever to do with weight loss.
