Thanks everyone, it's really good to hear everyone's insight in to this.
Well in this case, I'll continue with this current regime of no breakfast / Huel for lunch / regular dinner - although I have to say, I'm noticing that with dinners, I have an appetite unlike anything I have had before! Last night I ate my dinner in record timing, like some kind of neanderthal!!
I think my body is still getting used to a lower calorie intake in the day, as I am struggling with exercise in the evening after work too as my energy levels feel a little lower than usual - so it's probably no wonder that a lower calorie intake in the day combined with exercise is making me so hungry for a fuller dinner.
So it does raise the question for me that perhaps if I had breakfast, perhaps I wouldn't feel as hungry in the evenings?
