No need to spend three months. The body raise all kind of signals in reaction to food, almost instantly.
Even for short-term goals anything non-measurable is highly prone to confirmation bias
Are bathroom scales also affected? Are keto test sticks too?
For many of us who care to research nutrition more than superficially the goals tend to be more long-term ones like not developing Alzheimer's, cancers, atherosclerosis, organ failures, etc.
Don't worry. Considering the level of aggressiveness industry has shown against low carbs diets, if any of those scares had any minimum basis, we would know by now.
Look, this post is no longer in front page, so it's doubtful anyone except us is reading it. I take for granted that you genuinely think what you say and hope you give me the same benefit of doubt. I haven't done keto in like twenty years? (not sure) but I can't tell you this: it works. Last time I did it, I spent two years in low carb with no adverse effects whatsoever. I ran every other day, was in a very good shape.
I can't help chuckling when I read hit pieces like what Wikipedia has to say:
https://en.wikipedia.org/wiki/Atkins_diet
If you read carefully you'll see that they suggest that it doesn't work at all and that it's just placebo, "nutritional nonsense", water losing or simply caloric reduction due to unpalatable plan. That's idiotic, as you can see if you go to other more technical article:
https://en.wikipedia.org/wiki/Ketosis
Surprise! It seems that there is actually a non-contentious, perfectly known mechanism to burn fatty acids induced by fasting or reducing carbs intake.
Try to reconcile that with: The Atkins diet is promoted with questionable claims that carbohydrate restriction is the "key" to weight loss. Questionable my ass. That's what the diet is and it works. If you don't like the kind or food you need to eat to follow the diet, it's OK and it's really the reason most people quit.
If you're worried about unknown long term risks, choose your poison: do you think it's safer to be fat? can you achieve the same results as easily with other diets? Power to you. But don't believe the army of liars that's been spreading FUD consistently over the years.
