What is a "free food" ?

I got an e-mail from one of my readers and he wanted to know what they mean when they say it's a "free food" ?

Well Dan here is the answer...

A free food is any food that contains less than 5 grams of carbohydrates and has less than 20 calories.(Yes, I count the calories too) You should limit all free foods to no more than 3 servings a day spread out throughout the day.
