I do live a fairly sedentary life too. The point of aerobic exercise such as cycling is to counteract that. I log my exercise on Strava, which reportedly has 50 million MAU. I'm sure at least half of them (+ many millions of non-Strava users) could do that easily (or equivalent in their chosen sport). Still an edge case?

"Watch your energy balance", "watch your weight", nutrients, processed foods, etc. I would consider generally good advice. "Sugar bad" or even "added sugar bad" certainly not.
