I've been on a low carb - keto diet for over a year. I didn't do it to lose weight, since I'm already underweight if you care about BMI. I did it for general health reasons. It's been pretty great. I feel that I can eat as much as I want and not lose or gain weight. I don't think I am actually eating any more calories - I just feel fuller faster. Within the first month or so I got a lot more muscle definition despite not going to the gym (I did start frequenting the gym later, though). A lot of it had to do with not having much fat in the first place, but it was still a nice benefit. I think the biggest thing I noticed is my knees stopped hurting. I have bad knees and it got to the point where I couldn't walk down stairs or bend down to tie my shoes without knee pain. In winter I'd wake up at night with my knees throbbing until I "cracked" them. After a couple of weeks in keto I could bend down and do anything else without pain. After I started going to the gym I was careful with squats for this reason, but soon realized that I can squat heavy and not worry (I'm still cautious, though). The times I've fallen off the wagon the knee pain came back. Now, this is likely just some placebo effect and I know of no science backing this up, but if it works I'm happy .
