Anecdata: I dropped 40 lbs in 60 days a few years ago, which most people would say is pretty extreme weight loss. I didn’t have any of the side effects you mentioned aside from some light fatigue and not as good as focus, but it was really not bad. Operated at perhaps 85% mental capability most of the time and was able to exercise just fine.
