I can only speak from my own experience - an experiment on one person only! but here's mine:
Low calorie intake has been a feature of most of my adult life, was incredibly difficult to maintain because of severe hunger and weakness/fatigue, and an utterly miserable process with no time off for good behaviour. Arguably it is almost impossible to maintain it over a lifetime, and I am a nutrition geek with an excellent knowledge of food values. Low carb is really easy, no hunger issues (if I'm hungry I just eat) I have good energy levels, BG in the non-diabetic range, and have lost a considerable amount of weight without expecting I would. Intermittent fasting just happened along the way - I had no intention of actually doing that, but as it offered itself because I didn't get constant hunger problems, I started it. I am now a normal weight for my height. I can keep this up for the rest of my life.
For me it was very much what I ate not how much of it. I realise we are not all the same, and equally not every dietary regime works for everyone. I don't dispute that low calorie regimes cause weight loss, but how many people can stick to those over the rest of their lives? Certainly I am not one of them.
