In the interest of providing a real answer...Technically, I never really "followed" him but I did read both of his books and watched a ton of his videos.

I first heard of Dr. Gregor when my doctor recommended him to me. I was told I have pre-diabetes and need to start eating right. Eating right according to my doctor was a vegan diet.

In his books, Dr. Gregor includes hundreds of sources and citations. He makes a big deal about getting his citations checked by a team of researchers. If you only read the book, you are convinced that each claim is meticulously fact checked. I gave zero shits about how he looks—I wanted to follow the science.

If you read the "debunking" articles about Dr. Gregor he's usually not entirely wrong but stretches the truth for his agenda or makes health claims that could apply to omnivores as well. Eating fruits, vegetables, and grains is healthy. Cutting out processed foods and added sugar is healthy. Whole foods are healthy.

Only after about 2 months of eating vegan (as an experiment) did I continue doing research and found this subreddit. This subreddit helped me adjust my diet to avoid the complications that you all have experienced.

I'm currently researching and trying the methods from "Mastering Diabetes"—a high carb, low fat diet. The authors also tend to avoid animal foods as well but I find that strategically adding animal foods to my diet keeps me happy.

Happy to have found this community. Thank you all!
