It’s the calories, dummy.
You may have read recently about the Kansas State University nutrition professor who lost 27 pounds while eating a diet rich in… Little Debbies. Mark Haub reportedly went from 201 pounds to 174 pounds over two months; his meals were centered around packaged snacks, sweet and savory, such as can be bought in convenience stores. He augmented those snacks with canned green beans and celery sticks. He also took a multivitamin and drank a protein shake daily.
