I'm not promoting a diet devoid of fruit.
To clarify, a diet devoid of "sugar" is a diet devoid of "sucrose", aka "processed sugar". Sucrose causes all sorts of trouble for the human body/
The sugar in fruit is "fructose", and while you can overdo with fructose, it takes a lot - something...
A low/no sugar diet would be helpful though, from experience and medical literature. Refined sugar alone produces many of the symptoms FluffyButterfly mentions. Avoiding refined sugar obviates many health troubles.
I just find it fascinating that the DnD that I loved in university a quarter century ago is still going strong! And I have to agree that dating your Dungeon Master/Game Master could be very..... awkward, indeed. Though I knew a number of couples who played DnD together.
