"PS.. Maybe you should look up the rates of diabetes among vegans by the way... And see how veganism is actually a treatment for diabetes.. "

So is the Atkins diet.

When you eat only vegetables, it can be difficult to overeat, as many vegetables are calorie-poor. But it depends on the vegan diet you eat.
If your vegan diet is salads, great! if your vegan diet is donuts - you're going to get diabetes.
If you eat only raw vegan foods, you are really going to shed weight.

But then, if you ate only cardboard, that would also be true.

All your studies showing veganism to be better than meat diets have one MASSIVE confounder. People who are Vegans are likely to be food nazis, watching what they eat like a hawk.

It is far more likely that a meat eater will eat a donut than a vegan will.

So you need to compare meat diets no carbs against vegan diets no carbs, against meat diets with carbs, against vegan diets with carbs.

What you are likely comparing is someone who eats a meatburger on a bun with someone who eats salad for lunch.

So go compare a PALEO diet person with a vegan who eats deep-fried carb-heavy meals.

Now come back with the comparison.
