Another personal anecdote countering this: I've always showered at least once a day (two if exercising or in a hot and humid climate). I can personally smell my BO at the end of the day sometimes. Last year I was at a week-long outdoors-event with lots of moving in the summer where we only washed off every other day in a lake and for various reasons didn't manage to get a shower before traveling back to a large city. I didn't smell myself at that point but was quite self-conscious that I probably reeked. Apologized profusely to my friend I met up with there and they didn't know what I was talking about, even after asking them to awkwardly confirm up close. This is a friend that would be bluntly honest if I did indeed smell. I do think there is something to that reducing soap/deo/shampoo use can be beneficial in reducing overall BO. But diet is certainly a factor here too - I never had as healthy-looking skin as when I gave up alcohol for an extended time. Also stress. I'm back to daily showers since, but only shampoo once a week now.
