bantam, there was no way I could have gone without breakfast, etc, when I first began IFing.
In fact (this was before the Horizon programme), in the beginning, I went down to just half my calories on two days a week – and still lost around 8lbs in about 5 months – without actually intending to!
If you look at the current thread you’ll find new posters starting off with 700 or 800 calories – or even 1000.
Great stuff, pointless! Not only is it cheaper to make your own bread, you control the quality of the ingredients you use. Tell your hubby to have a look at some of the recipes on my blog – we could do a recipe swap! 
have bought flour and yeast a while ago with every intention of doing it but not yet got around to it.
Hi sporting
Do you have any spare time over the weekend? You only need about ten minutes initially – then an hour or so gap whilst your bread is rising – then half an hour monitoring the bread in the oven; probably wouldn’t take more than about 20 minutes in total out of your schedule.
Bit longer if you’ve kids around – but you’ll be giving them a skill for life.
If you’re on your own, I’d suggest a loaf of bread to begin with. As pointless said, 3 loaves for less than a pound.
If you have children around, perhaps some jam doughnuts. Cheap and cheerful – but very tasty.
Or if you have a bar of chocolate to hand, why not make pain au chocolat with them? Here’s a post about an on-line breadmaking session I ran several years ago on the old BBC Food boards. Loads of pics and tips.
