I don’t understand the connection between diabetes an not eating cheap factory farm meat. Sounds like you got the wrong info for a healthy diet.Why would more type 2 diabetes be "fabulous"?
Not everyone does well on a diet composed largely of cheap carbohydrates.
In general you can say that veggies are way more healthy than meat.
Eating just ½ a portion of meat and double the amount of vegetables has proven to be more healthy without any other changes.
You need to make some changes if you delete all the meat. You shouldn't just take the meat off your plate. In addition you need to add some beans, seeds and nuts for good proteins, iron and such.
People who change to a vegan lifestyle improve their health if they do it wisely (in general). And it’s better to change step by step. Not change your habits overnight or your intestines will protest.
