Well after being on OMAD diet for 19 days and loosing 15lb I noticed lately I was getting headaches, not uge ones but weird feeling ones, weird because I never get them, beside that I have been feeling great, training, walking 5miles 4 times a week, but wondering what was the cause of those mild headaches, took my blood pressure for good measure, Holly s*it, 180/100, usually 125/80 with meds, I most suffer from some kind of imbalance, so I ate something and my headache was gone and BP went down to 160/100, I'll take it again later on. One thing for sure I'm getting off OMAD for some time until I stabilize
