Grabbing a 100- calorie snack pack of cookies or pretzels many seem virtuous,but it's more likely to make you hungrier than if you ate something more substantial,says Amy Goodson,RD,dietitian for Texas health Ben Hogan Sports Medicine."Eating small amounts of carbohydrates dose nothing but spike your blood sugar and leave you wanting more carbs."Goodson recommends choosing a protein such as a peanut butter or string cheese with an apple."They are higher in calories pre serving,but the protein and fat help you get full faster and stay full longer=and you end up eating fewer calories overall,"she says.
