As I found out and mentioned in a prior post, becoming an accidental vegetarian is likely to lead to health problems, as it did for me. If you wish to eat vegetarian-style, talk to your doctor, and talk to a registered dietician, take supplements and have your blood tested at least once per year.
Here’s a good list of things to watch out for: https://www.healthline.com/nutrition/vegetarian-and-vegan-mistakes#TOC_TITLE_HDR_8

Again, vegetarian eating is not something you can just casually decide to do, and gradually drift into by reducing or ending meat consumption. You need to follow expert advice and track your nutrients. If you don’t you could end up like I did – 5 to 10 visual scotomas (blind spots) per day, weekly visual auras lasting 30 minutes, up to 3x each occurrence, and a full migraine about once per month, periods of extreme dizziness, hair shedding, fatigue and brain fog. I also experienced heart arrythmia and the B deficiency was a likely contributor [1] to causing an eventual blocked artery in my heart. If you wish to eat vegetarian, do it right – not like I did, as an accidental vegetarian. Doing it wrong could kill you (no joke).
[1] Vitamin B deficiency was first identified as a significant risk factor for artery inflammation, back in 1969. However, it was largely ignored as it went against the long-standing focus on dietary fat and cholesterol. Today, vitamin B deficiency is a recognized cause of artery inflammation, and in the absence of other risk factors, becomes a significant risk factor in heart disease – possibly tripling one’s risk of heart disease. To learn more, read the books by the late Kilbur McCully, MD, who made the initial discoveries. You can also search Google Scholar and find many newer papers on the link between vitamin B and heart disease.
