A bag of chips, ice creams or burgers as snacks can give you a high count of calories. According to a registered dietitian and personal trainer based in Salt Lake City, a true snack is only about 150 to 200 calories. Here are several of her healthful snack suggestions that fit the bill.

  1. A cup of high-fiber cereal (like Kashi Heart to Heart) and a small handful of pumpkin seeds.
  2. One ounce of nuts, which is about 24 almonds or 15 walnuts.
  3. Nuts are nutrient-packed but calorie-dense, so limit consumption to one or two handfuls a day.

  4. One cup of bran flakes with half a cup of chocolate milk.
  5. One handful of red grapes.
  6.  Freeze them for five minutes to make them sweet and crisp.

  7. Skinny Cow brand ice cream treat.
  8. Whole-wheat toast-be sure it's 100 percent whole-wheat-with a bit of peanut butter.
  9. One stick of string cheese with a piece of fruit.
  10. One whole-wheat tortilla with a few spoonfuls of canned black beans.
  11. One serving of Greek yogurt with a handful berries.
  12. Any fruit or vegetable.
  13. For more protein, also eat a serving of nuts, sliced turkey, or a low-fat yogurt with less than 20 grams of sugar per 8-ounce serving.
