Interesting. I guess it depends on the kind of exercise you do.
What I noticed is that around day 7 or so, anaerobic exercise (e.g., thai boxing) becomes very demanding and hard to keep up for more than a few minutes at a time. However, it's just as easy as always to do aerobic exercise like jogging or swimming.
Never had dizzy spells or feeling of muscle fatigue (except for anaerobic exercise) - and it was also easier to get out of bed in the morning.
However, a friend of mine noted that my body goes into a super-economic mode - that I hardly lift my feet off the ground when I walk (less than an inch on average), and that my arms seem to move quite a bit less.
I wonder if the insertion of lemon juice is enough to counterbalance the dizzy spells. I recall doing long walks but not any jogging while doing longer fasts.
I'm very surprised by the lack of muscle fatigue though. I've done fasts of 4+ days 10+ times and I always get significant muscle fatigue around that point (esp. in the hamstrings).
Very curious now what causes the dizzy spells. Please send me a github message or something if you ever find info. This is a long term interest of mine.
