Many patients ask me what they can snack on in between meals.  The correct snack should meet the following requirements:

1. Contain less than 500 kilojoules
2. Have less than 3 grams of fat
3. Contain low GI carbohydrates to maintain your blood sugar levels therefor providing energy and preventing hunger.

A good example of a snack that meets all these requirements is 100ml low fat Yoghurt. One step better is a fruit (the size of a tennis ball).  Any and all fruits are great choices except for watermelon and over ripe bananas that has high GI values.
