A vegetarian diet is healthier for you and the planet.
I am afraid this is too broad a brush. I upped my oats, fruits and orange juice and within 1 month ended up with a HbA1c of 134. I was eating meat and fish also at the time. I dropped the high starch vegetarian foods (rice, pasta, potatoes, bananas, grapes etc) kept the low starch vegetarian friendly fruit and veg (berries, broccoli etc). Throughout I kept the meat and fish ditching vegetable oils and am now in remission.
Vegetarianism can work, but please note the diabetes rate in parts of India that are vegetarian for example. Another point on meat is that all of the studies use relative risk (which in my view should be banned as it is like a financial adviser saying last year I made you £1 profit on £100, this I have made you £2, haven't I done great making a 100% profit ). If you have 2 cups that look the same size to the eye, with relative risk you can say that one is larger by 18% - this is a con, when the actual difference is 1.1% - the "absolute" risk (which for me is the only truth) - this is what they did with tests on processed meat . As a general average person if I said your chance of getting cancer is 5 in 5500, but if you eat 50 grams of bacon from now to death and your chance of colorectal cancer is 6 in 5500, would you see that as 18%, it's a lie. Don't get me wrong, over charring meat is not great, and I feel nitrates should be removed from processing...I also hate for example mass produced chickens that cannot stand. But for what I would class as traditional meat, an ancient food is not the cause of modern ills - another lie (more likely vegetable oils and high carb / sugary foods).
The Vegetarian / Vegan movements are well financed and have religious and other massive organisational structures behind them. LCHF / Keto are less organised, so when mass media statements come out it is hard to challenge the truth. So for example does it matter that a recent Oxford study showing meat to again be bad had Vegans behind it - this was not in any of the reports, but again a non interested member of the public would take this as fact because of the credibility of Oxford university.
Regarding the environment reported numbers have been classed as fact even when the originators of reports have pulled them due to be admittedly wrongly calculated. Water use has been added to what cows use even though the rain that falls would have fallen on the land in any event - again a miss us of statistics. Swapping animal farming for grain and soy equivalents depletes soil quality, nature knows best and has always been better than woman / mankind modern techniques. I would ask that you review this video by an expert on a par with any of the Vegans who promote their world view for some balance:
Just one further point if meat were so bad why is this not showing up in "our" blood tests, diabetics have got to be one of the most tested populous out there - my markers are great, even after pounding additional meat and fish in the last 6 months (diabetes damaged my kidney function from the 70's to 60's eGFR, I dropped 1 point after doubling my meat and fish intake (and gained loads of muscle).
