I'm a woman and have noticed that I have gained muscle on this diet without doing any lifting.
I don't find eating this way difficult to do at all. I like the food a lot and it calms my appetite. Because it's so tasty and makes me feel good, it's totally self-sustaining. I WANT to continue. I don't want to go back.
I found low carb to be very helpful for getting the ball rolling. Once I converted my body to using fat for energy, that made me more flexible for my endurance activities. It gave me more sustainable energy. I can go all day hiking without eating. Adding back in more carbs (roots and tubers at dinner) has helped me increase strength and speed during those endurance activities, some of which I lost on low carb. I honestly do not think I could have done as well without the low carb period first to get things started.
I don't think it's hard to stay low carb. Lots of people do it. I find it hard to eat a lot of carbs now. But I do make a point to eat some every day in the form of roots and tubers most days, rice once in a while (tonight we're going for sushi!) Once in a while some fruit.
