In reply to Vicky.

Thanks for the reply Vicky! Ok I get it. I'll stick to plain coffee just fine. I also do fasted cardio at the end of the fast and then I eat my first meal. Also do HIIT in the evening. So since I am doing the keto diet, and I will be in ketosis, if I do fasted cardio while fasting, then technically I am burning 100% body fat??
