I’ve been doing IF for almost 2 months now. I dont have a regular routine; some days I go for OMAD and some days I’ve a 8hr eating window. Recently, I get a feeling of fainting or lime a long lasting intense headrush, eyes go blind, light headed, sweating, immediately want to sit down. This goes away after I sit for a while and have a tea with some sugar, thereby breaking the fast, because I only get these when I’m about to reach almost 20hrs of fasting.
Has anyone had these problems when doing OMAD?
Edit: background: Im 23 years old Male with hypothyroidism and no other diseases or conditions. Weighs 70Kgs and 175cm tall.
No clue your gender, height, weight, medical background etc but it’s definitely sugar related. If you’re overweight you could have diabetes and not know yet. But if I were you I’d stick to a 16:8. They achieve the same end point and for you it sounds like you’ll have less consequences.
These are the symptoms of hypoglycemia, or in other words, your blood glucose level has suddenly dropped lower than the minimum desired level.
It happened to me too once even during my eating window, when I ate oatmeal with banana (which increased my glucose levels) and didn’t eat anything else for 4-5 hours.
To prevent this during your fast, you might need to eat a bit more in your eating window, so you’re not too restrictive there. Make sure it’s healthy, whole food with mixture of carbs, protein and fat and you’re feeling satisfied but not too full.
I’m not a professional and you might find other solutions if you google it up, but it helped me to avoid this. I have hypothyroidism as well.
*edit: grammar, more context
It could just be that you’re not drinking enough with reduced number of meals, making ur BP go down. So ensure you keep hydrated and eat a salty snack when you feel this way. Or just have some salt water if you still wanna fast. If that doesn’t help, then I would see ur doctor.
