It's really "Vegetarian Diets May Be More Effective for Weight Loss" for people who have Type 2 diabetes AKA are already eating very unhealthy diets, and versus the control group eating diet X. That's two separate enormous caveats.

I want to see a vegetarian diet for weight loss vs a high fat high protein meat based diet, a la: http://www.empiri.ca/p/eat-meat-not-too-little-mostly-fat.ht...

> The vegetarian diet (∼60% of energy from carbohydrates, 15% protein, and 25% fat) consisted of vegetables, grains, legumes, fruits, and nuts. Animal products were limited to a maximum of one portion of low-fat yogurt a day.

> [non veg diet] contained 50% of energy from carbohydrates, 20% protein, less than 30% fat (≤7% saturated fat, less than 200 mg/d of cholesterol/day).

What is less than 30% fat? Were they encouraged to eat low fat foods? Were some of them eating only 10% fat?

To any high fat/keto/low carb adherents, these sound like crap diets.
