Thanks for all the good advice folks. It seems that a complete change of lifestyle and diet are in order.
I have in the past managed to eat a lower fat diet, and combine it with a varied exercise routine, including weights (light weight, many reps). This resulted in gradual weight loss, but as soon as I relaxed the routine, the weight would creep back on. This cannot be good for long term health, so it looks like a permanent change is needed.
Thanks again everyone for your thoughts.
Safe flyin'
