Though (and this is no personal slight!), I suspect 5'6" is below average height, so wonder what the average waist size per height is...
I'm about 4st over what the charts say I should be, and just under 2st over what is 'skinny' for me. My ideal weight is about 12st, I remember being weighed at that at an asthma clinic and the nurse looked openly confused as she looked at me, then looked at the chart, then looked at me, then looked back at the chart before concluding "nah, you're fine".
I went from 12st, and at my heaviest I reached 15 1/2 st mostly as a result of getting married (I married late) and eating actual food for the first time in adulthood. I actually got stretch marks as I put the weight on so quickly!
I used to basically just live off of pasta before that, no breakfast, no lunch, just pasta for evening meal, that was the last time I was 12st. Of course my wife wont let me do that now despite my hatred for breakfast, I have to force that in in the morning, I boak every morning eating breakfast still, but I need the calories for the cycle to work, so what do you do? Hate breakfast, sick if you don't have it.
I'm hideously unfit
Probably subjective, my body has grown used to the demands I place on it . Over 100 miles every week now, have been at that for more or less the last 7 months. It recovers incredibly quickly now, I've done 95miles this week so far, and I'll be good to go again tomorrow. I can't do it fast, I average about 11.5 / 12 mph in the winter, and 12 /14 mph in the summer, that frustrates me, somehow I still imagine I'm 20 and can cycle as fast as I want, and not some 40 something fat person with chronic lung disease. I probably actually do all right considering, still, frustrating.
But, back to that subjective thing, ride 30 miles a day, day in day out for months on end. No problem. Run up a single flight of stairs? Crumpled mess at the top. I couldn't run for a bus....
Hmm, I seem to have gone on a bit, how'd that happen? I am largely sane, I think, despite some of my mutterings. ;0
