@HRTQueen, me too. I think DD is right. I'm not 'fat' but I am overweight and I am going to be down about that on holiday.
Made a start yesterday although I'd already had breakfast so didn't manage the 16 hour fast.
I have managed it so far today. Counted down the seconds until my lunch of:
Chicken salad,
10g of salted proper popcorn,
Arla protein yoghurt pouch.
Had a tiny handful of nuts with a cup of tea mid afternoon.
Am currently cooking some chicken and veg for dinner.
Not sure if I'm really nailing the food exactly but that comes in at 800 calories and the overriding point is I've stuck to it.
