The only reason a dealer would dose weed w anything is if the weed sucked and he still wanted to move it. It's almost hard to find shitty weed these days. There's weed that's less good, but I haven't seen actually shitty weed in 20 yrs. No dealer has any good reason to lace weed w drugs they can sell.
I have come to believe, it's a complicated and individual answer. There is CICO, genes(which do play a part), the rise in HFCS and other highly processed "foods" and gut microbiata. Your gut biomes plays a larger role than most acknowledge. CICO is the norm, it is baseline. But when a person spends a large portion of their formative years eating trash, it fucks up your gut biome and in turn that screws up CICO.
And fat people just Do Not move as much or as intensely as a fit person. They will absolutely do the least amount of physical work possible. Take the stairs? nope. Park farther out and walk? Nope
There's a lady at work. She's probably 4'10" or so and built like a pear. Enormous wide hips and butt. She eats lunch at the same time I do, so I see her lunch. It's always decent stuff she cooked at home herself, it isn't as a rule what I'd call goyslop. It isn't excess amounts, and I don't think she gorges at home. I've never seen her drink a soda. She will never be svelte. Her genetics aren't playing that game. But if she does any exercise I'll bet isn't intense or long. And her gut biome might be fucked up too.
All that said, fuck fat people. Most don't even try. They just make excuses and expect me to gladly surrender part of my airplane seat.
It was probably an attempted virtue signal which went totally sideways. They wanted to show the woke what a great company they are, then all the actual customers said yeah fuck that and you.
There never was a way for them to do so. They knew they couldn't.

Kill yourself. It's the only contribution to humanity you can ever make.
