I am not fully sourced and cannot provide any citations at this time, but something tells me a deeper dive will expose my hunches as truths.
I am convinced that people are obese because they are being poisoned. Not from overeating solely. Specifically, I believe that there are many trace poisons all throughout the products being sold as 'food' and that it is causing massive levels of poisoning to occur which is just accelerated by overeating.
The fact that they include additives to make the food taste unlike its natural constituents combined with known poisons being added discretely we are getting fatter and fatter. Because fat is actually not just an energy storage mechanism. Fat is a protective barrier and provides a lipid shield to protect the body from absorbing the harmful substances.
Many animals as they get older acquire hard fat lumps and mostly these are in animals which have liver damage or kidney or some other issue because they cannot clean their blood properly and are being poisoned beyond their ability to heal.
I believe that most of all food being consumed when it is not prepared from raw ingredients is contaminated and causing the inflammation to make their bodies generate fat for protection. This in turn fuels a massive economy (since the 80's) around fixing the issue through subscriptions that do not actually address the poisoning.
Most of the problems are originating with meat products.
All kinds of hormones and thyroid disrupters are injected into animals to make them grow faster. Then, right before being slaughtered, they are given another drug that increases water retention.
If you don't believe me, go completely vegan for two weeks. You will lose between 7-14 lbs, but you won't go down in clothing size. The weight density, probably the water density of cells, goes down. I wish I had monitored my blood pressure, I'm sure hypertension may be another byproduct of livestock injections.
Later, you will notice that any break from the vegan diet will noticeably add weight. The amount of weight gain won't correspond to the number of calories taken in.
Fast foods are exceptionally bad. The corporate fast-food farms are the worst when it comes to injecting animals with hormones, and drugs. You will feel hungrier after eating fast food a few days. Those animals are given appetite stimulants to eat more. You literally become the goyim-cattle.
The same thing would happen if you did carnivore. You'd likely lose a lot of weight, and gain it back when you started adding the vegan carbs back.
Yeah, they add a bunch of toxic crap to mass-produced grain-fed meat, but it's even worse what they add to fruits, vegetables, grains (not to mention all of the natural toxic, carcinogenic pesticides that vegetables contain).
I've never felt better than when on carnivore eating only local, grass-fed beef, some organ meat, eggs, fish and that's it. It is incredibly hard to stay on that diet though in the modern world.
Vegan is much easier to stay on because the system has decided that's what they want the slaves eating, so it is everywhere. Yes, eating raw, natural vegan is better than the processed carbs, but the data is undeniable that we evolved to eat primarily meat.
That said, if what you're doing is working for you, there's no reason to change. If you're having problems (auto-immune, inflammation, weight), I'd really suggest carnivore for 3-6 months as an elimination diet and slowly add back minimal raw unprocessed carbs after that until you notice the problems coming back.
Just buy meat directly from a farmer you trust. Vegan diets are void of any actual bio available nutrition!
