I work a manual labor job and I lift weights. Should I only dryfast on days I’m not lifting and working? I get headaches and really tired.
I am about to do a 7 day fast, and I am choosing to do this while on a staycation at home.
Unless you have done this before, I would not do anything strenuous while attempting dryfasting as it will increase your energy depletion. Consider giving up the weights for the fasting period and also doing it on vacation. Going without food and water is hard enough why make it harder by doing everything you usually do except that? I have a whole plan to change up my activities and schedule to lessen the feeling of deprivation and boredom.
Working a manual labor job is exceedingly difficult on a dry fast. I imagine the more experienced you get the easier it can be to dry fast while working. I think i made it up to hour 5 of working before i needed a drink. Very difficult. I’d invite you to try for yourself and report back.
