Is keto the superior diet?

In 2024, in 12 days I lost 16.8lbs eating a keto diet, where I've only lost 12.4lbs this go round eating a normal diet in 12 days.

So do I need to go back to eating keto to lose weight faster or continue eating a more sustainable diet?

I want to do the one that will ultimately have me stick with it vs lose the weight quickly only to gain it back like I did in 2024.

I have a lot of weight to lose. Like 206lbs to lose.

I would like to lose it in a year.

I know that will require lots of cardio and weight training as well which I have started doing as well. But I know diet is the most important component to losing weight.
