we had a nightly Friday bike rides in my city, think making a 60 km circle with multiple stops from 00 to 9 a.m.
I usually took 2-3 king-size snickers with me, because it's a sourse of carbs that doesn't take a lot of space and doesn't cost much (I'm looking at you, "fitness" bars)
I use it as a temporary fix if I’m very hungry while I’m out and about and can’t get a meal immediately. It’s more filling than a pure chocolate bar because it has nuts.
Yes, what it is, is a sugar rush that sometimes makes you feel energised if consumed in smaller quantities. But a whole bar is way too sweet for you anyway.
Sugar high has been disproven so many times. If it occurs at all it's psychosomatic. In children, they get excited because they're getting a treat and go nuts. None of it is from the sugar.
