There are alternatives to standard keto, I do a hybrid of targeted and cyclical keto. I did standard keto for 4yrs, great for the fat loss, reversal of insulin resistance etc, but hurt me in the performance and ability to hold onto muscle. There’s also a lot leaning to prolonged super low carb hiring thyroid function, which was absolutely the case with me. Learned that after the fact and went back in labs and it was getting worse slowly the whole time.
I’d disagree with a minimum of 250g a day though, that’s not a lot by normal standards, but once you liver is full of glycogen, and your muscles get the rest, anything beyond that can start working against you.
That’s said, healthy carbs aren’t going to hurt you, but make sure you have a real idea of your metabolism as well. If you’re not tracking and just eating ro satiety, that’s be my first fix. Absolutely no shortage of us can’t do that, keto or not. If I ate to satiety I’d be 300lbs again, zero question about it That’s on top of me using Semaglutide to beat the appetite down.
Macro trackers like MacroFactor figure out your actual metabolic rate, no shortage of people are ahotting themselves in the foot without realizing it, I know I was. Which prior to having my RMR actually tested, just ended with me getting more and more drastic, fasting, allowing my metabolic rate ever more, I started on a home, and then dug it into a crater. Took over a year of reverse dieting to fix it, not fun!
