No shit, we’ve known this for literal decades. You can get addicted to pretty much anything.
There’s a big difference between something being psychologically addictive, and something being chemically addictive.
Like, yea, you can technically get addicted to anything. But there’s a massive difference between getting addicted to, say, working out, and getting addicted to nicotine.
So food being chemically addictive is not something that’s been known for decades, in fact it’s been a common topic of debate.
Idk. My wife must workout or she is irritated all day. Working out can be like a drug.
