Definitely, most people switch to vegetarian when they realize they are getting sicker and have no other solutions. Avoid the bad stuff like wheat/gluten products, avoid soy products, avoid fried, and add a lot more raw fruits and some raw veggies/greens too. No need to be 100% raw, but the extreme health guru's go almost completely raw.
Best bet is to find role models, books, youtube, instagram? depends if you like reading or keeping up with current trends. Some of these youtubers or instagrammers are also coaches if you need such.
books like, Prof Arnold Ehret and his Mucusless diet healing system, Prof Sprira on YT and IG is a coach of this system.
Medical Medium, Anthony William, though not promoting vegetarian and friendly to most diet systems, all his healing recommendations are plant based. He is currently very active on most social media platforms like YouTube and Instagram promoting his new book, and talking about bad supplements to avoid, but his past videos may entertain you too.
Old videos by John Rose on Youtube, with his message of bio-photons diet from raw fruits will solve all of humanities problems.
Others like Fully Raw Christina, her older videos may be more informative, how she fixed her health problems.
One thing is to avoid the critics, or realize there are a lot of haters out there, trying to steer you away from health gurus that you may want to follow. There are many that claim their diet is the right one, so it sometimes takes common sense to figure it out, and everyone's common sense always differs from the next person so you may be creating a new vegan/vegetarian diet system that is suited for mostly you based on role models you follow.
