@sozobe,
Bingo, in my view.
I was thinking that maybe those who said they never had sweets were dieting, and, as we know, that's often a yoyo thing.
Reminds me of some of the critiques of the studies that say alcohol in moderation is good....a lot of the non drinkers in some of the studies had previously been alcoholics.
That being said, a degree of sugary stuff WAS there in the hunter gatherer diet.....honey was always much prized, people discovered sweet saps when they were available, honey pot ants are still consumed with pleasure by indigenous folk here, fruits.
It all turns into glucose.
