Allowing myself to drink sweet drinks while working has been the most profound performance enhancement in the past 5 years for me. For the past 2 weeks I've been outputting at +50%. Higher focus, longer. 1 Powerade at my desk per day. I am able to do 12 hour days the way I used to be able to when I was younger. I don't have any crash, I crashed much worse end of day when I was avoiding sugar. I am not sure why this is the case, it seems contrary to most of what I've read. Hypothesis 1: I burn a lot of energy working at a computer and easy fuel gets burnt off quickly, like with a runner. I was in a calorie deficit that was hurting my performance previously. Same reason chess players consume chocolate milk while playing. Hypothesis 2: I have diabetes? Any other ideas?
