What they are referring to is in the lower left corner. Bet you intially missed it and had evil thoughts

The commercial is from a time before protein 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.

People need to feel justified.

"I'm not eating this candy bar because I love sweets; I'm only doing it because my blood sugar is low. It's not candy, it's medicine."

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)

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.
