Vaguely asking, what is the best way to ride for fat loss while still keeping most if not all muscle? Would riding in the lower zones be better for this? I mean, my thinking is that when we ride hard we need to replenish our muscles with the foods that are needed to continue to do so - almost like we put back in what we just rode off, no? Riding with less intensity of course requires less replenishing, however less calories are being burned off. It almost seems like a Catch-22 to me. Is there a way to teach our bodies to use fat as fuel more efficiently? It doesn't sound like fat for fuel would be efficient. I'm sure my lack of knowledge in this subject hinders me. Please help. Thanks.
