It's a challenge for me. Less of a challenge than being hungry on a low-fat, low calorie diet (not to mention more effective and healthier in the long term, but that's another issue). I want to lose weight enough that I tackle the challenge every day. But it's still a challenge. And a big enough challenge that I've had trouble sticking to it over the years. The first time I lost weight on low-carb was nearly 20 years ago. Since then I've had stretches of low carb and stretches completely not--enough that I'm still heavier than the first time I started out.

I think it's easier than trying to starve yourself on a low-fat diet for the next few decades of life, but not easy. At all.
