I am planning for 5 day fast but every time I do so, i am not able to go beyond 20 hours. As soon as I reach 20 hours, i get severe headache and weakness. My head starts spinning.
Kindly help where am I going wrong ?
If you’re getting severe weakness just from 20 hrs you should get a blood test and look into your diet.
I always find the first day the hardest, but I’ve never felt weak even without electrolytes. This could be a sign of a deeper issue.
If you are taking electrolytes do blood tests and general examinations like lipid panels, thyroid, etc…. If you aren’t, take electrolytes! :D I was doing lazy keto (I guess around 50gr. of carbs/day) for about a month with sporadic intermittent fasting, then went to strict keto (\~20gr carbs) for \~3 weeks, then did my first 80hr fast with some headache, feeling cold, some sleepineses and weekness. then i ate normal for the next 4 days and now I’m again in the end of my second 80 hr fast and I feel much better, almost perfectly. Have never attempted fasting more than \~20 hrs without electrolytes though
