Whenever I fast I get the WORST headaches has anyone else had this issue and is there any way around it
What’s causing the headaches? Caffeine withdrawal/low blood sugar/not enough electrolytes? I’ve never experienced headaches while fasting. You can rule electrolytes out easy enough, just sip the mix noted in the automod’s response throughout your fast and see if that helps.
Likely either electrolytes out of whack (low) or dehydrated. Also miiiight be carb withdrawal. Could be something else but it’s not something internet strangers can just diagnose
​
If you go into fasts “dirty” (lots of carbs whether healthy or not, sugars, etc), try going in clean (keto style for a couple days leading in). Still headache? Mess with electrolytes (more). If you get bloated/nauseous/retained water and still headache, likely not those. Drink more water more frequently at this point. If that doesn’t help, you’ll have to do some analyzing and see if you can find potential triggers

As you explore to try to find the cause - change only one thing at a time. That’ll make it easier to find the issue
