Thanks for the suggestions. I think I'll have to work on Damage Limitation, or possibly Bulge Limitation for this year and make more changes next year when I have a different job.
At the moment I can't increase the cycle commute easily because it takes about an hour to get to work,of which the first 30 min is on a bike. I'd prefer to ride the rest of the way but Stuttgart is in a fairly deep valley so the route involves very steep hills and very busy roads. Likewise extending the cycling part, while tempting, would mean taking too much time from the family each day.
Jogging has the problem that the theatre has no shower (!) and I'd have to steam in the tram on the way there anyway which seems an antisocial thing to do, besides, I have a damaged knee and Asthma, so it's not possible anyway.
Just eating less may be effective if you're sitting all day at work, but I'm moving equipment about and running after my clients/up and down stairs/ladders all the time. When I tried eating less I got sleepy and lethargic and couldn't concentrate, and working with young lads with drug & psychological issues I need to be 100% present.
I never could skip. They tried to teach me at school but it never worked. I can design furniture in 3d in my head but can't coordinate my hands and legs enough to jump over a rope.
I think that is the main issue: I need to fit any Bulge Reduction Strategies into the existing work/life pattern and I have limited possibilities for change while working where I am. I need to be alert at work and for my family, and take a minimal amount of time getting between the two.
It looks like diet change is a promising line of attack so I'll try Bananas instead of bread at work, and I'll ask about a way to heat oats. I don't know if there's a local version of Oats so Simple, will have to investigate...
Since asking this I've been bombarded by online adverts for exercises to flatten a stomach but they haven't been mentioned by anyone here. Does that mean they are a waste of time, or is there some point to them?
