I loved keto when I did it - just step on the scale in the morning, see results, and voila, positive feedback loop.

The only downside that I can think of it was really, really, really, REALLY boring.

so boring in fact that after a while I did not look forward to eating - while normally I am a foodie and just love to eat, when I did keto that wish to eat was gone.

however I still would very much recommend keto if you can find the life setting that supports you doing keto, because I can guarantee you that other members of your family will not want to eat what you eat- once or twice, MAYBE, but not all the time.
