What does that even have to do with this thread? But w/e, the diet you're looking for is keto - zero carbs, which incidentally is mostly from grain, works. Meat and fat alone do not cause obesity, but together with carbs they fatten you up more effectively.
They don't necessarily cause obesity, but they sure don't help. I lost tons of body fat when I stopped eating meat and dairy/eggs. Literally the only thing that changed was I ate more fiber and less fat. And of course removing trans fat and cholesterol from my diet, because they are only found in animal products.
Too much refined sugars + animal products = fat population.
