Are you serious? Most of the plant substitutes for meat are based off nutrient-devoid grains, soy, and corn. It's also not at all an inefficient way to get calories; fat packs the most calories per gram, and fat (especially saturated fat) is not easily available in plants unless you're making a concerted effort to eat avocados, olives, and coconuts. I'd rather eat a fatty steak and be satiated for hours, than have the same calories from quinoa (or some other 'healthy' grain) and be ravenous 2 hours later when my insulin levels drop.
