Thread title. Wondering if anyone knows if taking some bcaa's and/or fish oil during the fasting part of an intermittent fast would "break" it and thus not really make it a fast any longer? As a side-bar, is there some caloric or other threshold below which the body is in a fasted state? Apart from the obvious. Fairly certain bcaa's/fishoil/multi are fine, but doesn't hurt to be sure. Thanks in advance for your help!
