I want to add the other side of the question, regarding specifically the formulas, as I seldom eat more that twice a day. I could elaborate some fruit eating to add a meal, would it count? or should I go for formulas taken only twice a day?
You do not have to eat after taking the herbs. The minimum 20 minutes before meals is to prevent the proteins or fats in a meal from blocking or slowing the absorption of nutrients or other compounds in the herbs.
