well watermelon is more simple sugar right and therefore ferments. ice cream is simple sugar too so wouldn't it ferment as well? you're saying like it would be good for backloading still despite the fermenting annoying shit?
one thing that I notice though is that I do IF and I fucking hate eating sometimes because it ruins my stamina. I like doing high energy shit and then after I eat I just wanna veg the fuck out 2-3 hours after lol
