Yes! Whenever I get a headache the first thing I “do” is stop eating.
Your body spends tons of energy on digestion, when you’re sick you’re already weak and powerless, so adding more tasks to your body (digesting) will only hold it back.
Fasting and taking vitamin c supplements every hour is the way. You will never experience headaches the same.
Not a doctor, I read about it in a book a while ago and am currently speaking from personal experience.
Well, I have coronavirus and literally zero appetite. I eat once a day and feel good. I also do some other healthy stuff(long walks, Buteyko breathing) which makes my appetite go even lower(while improving metabolic efficiency), so it’s fine.
