Stacie,
We always want to respect our physicians and other health care professionals. Typically, the information that you read on this forum is going to be based on the Quick Start Guide that Medifast makes (you should have received it in your order. It has a list of allowed snacks (1 per day) and on that list is 2 pickle spears.
We do lose alot of sodium, potassium, and other electrolytes from the water we drink each day. Most of that is replenished in the Medifast meals and our Lean and Green. Some days we get more, some less. When we feel a little light headed or get leg cramps, we need to have some boullion or a fast soup, or dill pickles, or something else with sodium or potassium.
Its a great plan. I would say, if your doctor tells you specifically that something is okay, then follow their guidelines.
Hope this helps ease your mind. Have a wonderful rest of the day.
