This is my first day trying to stick to 20:4 and I have a headache. I tried taking electrolytes with water, but it didn’t seem to help. I’m not really hungry at all, just have a massive headache. Will this eventually go away as my body adjusts? I’m trying to do OMAD and eating window 2:00-6:00 pm so I can have a nice dinner with husband/kiddos.
Very important to listen to your body. I started 16 hour fasts 6 weeks ago and just yesterday have been able to do 20 hour fasts. I gradually eased into it and listened to my body’s needs so I wouldn’t be miserable.
