About 10 years ago I used to commute to Carlisle. I had to be up at 6am and often didn't get home until 7.30pm. Well I couldn't face breakfast, hate mayo, so the only thing at the sandwich shop was pies and bridies or else it was lunch out of the vending machine. By the time I got home I was starving and craving high density food NOW and with no energy to cook. So while the pizza was in the oven I'd gorge on biscuits and cheese. This was when my diet was at it's worst. I found the best thing was the equivalent of syn free soup even if it's a pre cursor to hula hoops.
I still find that if life gets stressy I don't eat enough during the day and eating enough during the day is really key for me.
I don't think you should feel guilty about the hula hoops though. I think the syns are really about the proportion of different foods we eat so the junk is limited but not necessarily excluded. So as long as they are accounted for it's ok but it's much nicer to feel you chose them not your hunger.
