Well, it's pretty simple really - the breast meat is made up of fast-twitch muscle fibers, which are designed for short bursts of energy. This means that the breast is built for speed, not endurance, and as a result, it's got a lot more meat on its bones. Think of it like a sprinter vs a marathon runner - the breast is like the sprinter, all about quick, powerful movements!
Now, you might be wondering, what about the thighs? Don't they have a lot of meat too? And to that, I'd say, absolutely! The thighs are definitely meaty, but they're made up of slow-twitch muscle fibers, which are designed for long, slow movements. It's like the difference between a distance runner and a weightlifter - both are strong in their own way, but in different ways!
