Fasting when you need calories to take a medication

Hi, all! I want to try fasting some time soon, but I need some help with a problem before I start.I have to take a medication each night that needs roughly 200-250 calories taken with it to ensure its maximum impact.Does it still count as fasting if I fast the majority of the day, then drink something like a Carnation shake to meet my calorie need for the medicine? Will it throw me off majorly, or is this pretty common?Any advice is appreciated. Thank you! via /r/intermittentfasting https://ift.tt/gOWhmGF
