Please keep researching.
That being said Nutritional Science is an oxymoron.
I think you are overstating the risk and benefits of keto or any other way of eating.
You dont have to be full blown keto forever. Cycle to VLC diet - say 40-60 grams as day for a year. It might be ideal.
No one knows.
Certainly an ideal way to keto is more healthy fats. Monounsaturated > Saturated > PolyUnsaturated > Trans
And these foods aren’t good:
bread
rice
pasta
potatoes
cereal
sugar
rice
I think of Keto as tool.
Sounds like you used the tool well.
Surely you have learned that Carbs are bad FOR FRY You
I will say this … for me.
Options:
(A) Standard American Diet - rest of my life, probably gain 5-10 lbs every decade until I die.
(B) Lost 25 lbs on Keto, dabbled in carbs, mostly good ones, less saturated fats. Weight goes up and down. Go back to Keto periodically.
© Lost 25 lbs on Keto, stayed mostly keto the rest of my life.
B might be for you.
B is safer than A.
B is better for you and what “Your A” might be.
Is C better than B ? I am not sure.
C is better than A (As far as I can tell so far).
What am I going to do ? I’m C until I find reason to switch (which I haven’t) (aka C is the null hypothesis for me).
Enjoy the Journey.
