I don't really think it's valid on any level: the uptake and calories.
There are empty calories that don't sustain you, there are vegetables like cucumber and lettuce and celery that not only contain almost no caleries, they actually take MORE calories for your body to process them than are IN the dang food.
No one thinks anymore. As to uptake less is more, I will say my son quit sub0hming with very little difficulty. He wasn't exactly happy but through the worst of it in a couple weeks.
When he relapsed and bought a Juul, he had to TAKE up smoking to quit the Juul, "It was grosser," he said. That is in fact a testament to vaping supper high nic. Like a rat with a pellet less is sometimes not more.
I TOLD him after one puff (and I was a 3 ppd smoker) "I don't know what is in that but it is way too rich for my blood," and handed it back. I had to try it, and to instantly decide, "Do I want all the lovely customizable vapes I have, or the evil demon Juul and be a rat with a pellet until the politicians take away that pellet too."
I didn't even hear that many COMPLAINTS when flavors were banned, the pelleting rats moaned a bit and switched over.
I dearly would like to know the "proprietary ingredients" in that thing they might be used in mind control experiments I think.
