Dr. Schwartz:
Prepackaged hot chocolate is NOT allowed (unless
you have found a 0-calorie one that we are unaware of). You may make hot
chocolate using Walden Farms or other 0-calorie sugar-free syrup. On a
milk day, between the hours of noon and 6 p.m., you may use milk to make the
hot chocolate. Outside of these times, you may use the chocolate syrup
directly in water and heat it up on the stove or in the microwave.
