For me I found it useful to get a real idea of the amount of weight I needed to lose; to get to a BMI of ~22 I needed to lose about 20KG which equated to a typical airline baggage allowance – having recently lugged that around on holiday it finally (!) dawned that I was lugging the same around with me whenever I was riding and to lose it would make a huge difference to tackling hills etc.
I also did a bit of the psychobabble bit of actually working out whether what felt like hunger signals actually meant I was in need of food, or were instead just signs of being tired and/or stressed and/or bored etc (mostly the latter when it came down to it).
Also I decided I wanted to do what I could to reduce risks of high blood pressure/diabetes/heart attack stroke and all the other things that mean active life could stop many years before it should.
Finally I decided to drop the booze, puddings and snacks, but otherwise to eat pretty much the normal diet, and to try and exercise or at least not slob out mosty weekday nights.
Currently 1 stone down on the way to three stones down…..
