What you do do of course is eventually reach an equilibrium with your intake and stop losing which is what has happened to me basically since January-ish. THEN you definitely need to look at your diet. *Sigh* why do I like food so much?
Possibly, because you exercise a lot. HIIT reduces desire to eat, but only briefly - generally, the more you exercise, the more you have a drive to eat and the more you will crave food, and more you
like food. The studies I've seen (OD - I'll try and dig out some links - but for now, just go on Google Scholar and search "exercise and appetite") suggest this effect is stronger in women than men.
I believe DrMekon is something of an expert in this area.
If you can put up with being hungry, or you're lucky enough to be someone who doesn't get hungry after exercise, then exercise induced energy deficit probably works as a weight loss method. It didn't work for Banting, and it certainly doesn't work for me, at least, not when I'm on a Normal Western Diet (high carb) - the day after an audax, and I most definitely have Teh Hunger.
