Is it, though?

Your entire body and brain is a complex and messy chemical reaction.

The opening sentence of the wikipedia article on addiction currently reads: "Addiction is a neuropsychological disorder characterized by a persistent and intense urge to use a drug or engage in a behavior that produces natural reward, despite substantial harm and other negative consequences."

The page then lists "eating or food addiction" as examples, with food addiction being its own entire page.

Gambling? Porn? Sex?

These are all things that we acknowledge are possible to be addicted to to that are not substances. Not to mention that coke has caffeine which is a chemical substance just as much as anything.

You can pin addiction to anything as a personal weakness, including drugs. Why are some people able to smoke a few cigarettes or do a little bit of cocaine without ever getting addicted, when others are hooked on day one?

If there's one thing that's been fun to see as the outcome of GLP-1 drugs, it's that a lot of people seem to have a real problem seeing people better themselves the "easy way".

I find this attitude strange. I am a very physically fit man, I do not know what it is like to walk in the shoes of someone who has an addiction to food, but I do know people eat themselves to death. People deal with debilitating diseases that are directly linked to the amount they are eating. People literally destroy their body and live in the wreckage, and you think that it's not an addiction? If not an addiction what exactly is going on?

Seed oils (used in almost everything these days) contain a lot of linoleic acid, which is a precursor to endocannabinoids, potentially giving you the munchies. If eating gives you the munchies, making you want to eat more, I'd call that a chemical addiction.

I think avoiding bad foods is a better solution than reaching for drugs, but if the drugs help break the cycle, it could be beneficial.

The fact that people have this idea that "obese == unable to resist drinking 8 cans of coke per day" is honestly part of the problem.

People get addicted to gambling, and you don't put that in your body at all.

It’s the same thing. Obviously withdrawals and such are different but the core mechanism of disregulated reward processing leading to compulsive behavior engagement is exactly the same.
