This sounds every much like my experience. After being diagnosed with diabetes and greatly reducing the carbs in my diet, I lost around 25% of my body weight over about eighteen months. (Overall I'm down a third from my peak weight ten or so years ago.) I don't make a special effort to "diet" in the sense of eating less food, I just watch my carb intake. It's like I'm back in high school, in the sense that I don't put on weight even if I overeat (as long as I keep the carbs reasonable). I don't necessarily think it's the diet for everyone, but it is certainly the right diet for my body.
