I know muscle consumes oxygen (forget what it's called now) so having to much muscle can affect your cardio, but does fat consume oxygen? Is the decrease cardio with weight gain caused solely by the extra weight you have to carry? Would 30 lbs of extra fat have a worse effect on your cardio than 30 lbs of extra muscle?

All tissue consumes oxygen. Fat has a relatively low metabolic demand, as it's purpose is almost exclusively energy storage. So yes, it does consume oxygen,  but less so than muscle.

The reason extra fat reduces cardio mainly because people who gain weight are deconditioned. But fat also requires more work to move around without actually contributing to the work that you perform like muscle does.

Thank you. Watching this wrestling match I was fascinated by how the more muscular black girl was, to quote one comment "gassed out a minute into the match". Even though she looked more out of shape, the slightly chubby white girl had much better stamina.

Fat doesn’t but Digestion does, it’s actually the “science” behind fasting, we cut out rich foods that require a lot of oxygen to digest and all that oxygen and energy can be used in the brain. It’s why Byzantines wouldn’t make any major decisions without a weeks worth of fasting first.
