A lot of the ketogenic diets out there are artificial ones and they impose an artificial condition, which is high animal fat and high animal protein (butter and bacon).
You can very quickly go from something very good to something very bad, which doesn’t appear as very bad when you first do it.
It could be that when you do it you lose weight and you think,
”I feel good. I’m losing weight.”
And then eventually you could start having kidney damage, (negative) effects on IGF-1, atherosclerosis, plaque formation, etc…
A lot of these ketogenic diets come from nowhere,
but they (keto promoters) are able to convince
hundreds of thousands of people to do it.
