Yeah, I’m in that boat. I did have some sugar, but it was extremely rare, and IIRC got phased out more as I got older. I don’t think it was ever a hard rule of “no,” but more of a “have very little except maybe on special occasions.” I never developed much of a taste for sweet things to the point I quite often find muffins for scones unreasonably sweet. When I was doing mountain bike races, I had energy chews and bars. In hinds sight, that was probably a poor nutrition choice for my metabolism, and I now I simply have roasted and salted pistachios, with a sugar free electrolyte mix before and/or after the ride.

I also very much seem to be the exception here. Probably my experience more comes down to my own eccentricities. I have the eating habits and body type of a distance athlete; healthy but low weight, diet consisting largely of slow-burning foods like nuts, fruits and starchy vegetables. I am still figuring out what diet and training routine works best for me, but sugar, even as a mid-ride fuel is a hard no-go for me. I like putting in the work to be able to do extreme sports like mountain biking and snowboarding at a reasonably intense level all day long. I listen to my body and I know without a shadow of a doubt touching high sugar and certainly processed foods is not worth it by any means.
