Can you drink Ultima while fasting?

Could you please clarify whether it's advisable to consume Ultima while undergoing a fasting period? I'm particularly interested in understanding if the ingredients within Ultima would interfere with the intended benefits of fasting, such as autophagy or improved insulin sensitivity. Additionally, are there any potential side effects or contraindications that I should be aware of if I choose to consume Ultima during a fast? Your insights would be greatly appreciated.
