23:1 OMAD Beginner

hello !! was just wondering if randomly starting a 23:1 (OMAD) fast without trying fasting before is okay ? i’ve felt lightheaded a couple times but listened to my body and would have like one chicken nugget and even now during my fasting window had a small bag of pretzels. should i start with a more manageable fast or will i be okay ? thought i should also mention that im rather a healthy individual. i do vape, but thats it - i dont have any underlying medical conditions via /r/intermittentfasting https://ift.tt/kNcvBTQ
