I started off at 18 stone 7 in august and only 5ft 7" although I could always cycle quite well hills were hard work, Even at that weight cycled the length of Scotland with panniers over 4 days however I always used power(legs like the old man of Chris Hoy).
After a bit of reading I simply cut out ALL junk food,halved the amount of bread I was eating,got a turbo trainer(machine of evil) and started doing some gym work over winter(light weights,high reps). The biggest thing though was to change how I cycled, I stopped grinding high gears and started spinning a high cadence,high cadence burns fat as fuel. the weight came off fast,average speed went up 4mph,no more knee pain or lower back pain.

Luckily I still have the Hoy size legs

and the words I keep running through my head is power to weight,more power-less weight,weigh less-power more or any combination of those words! It workes for me, good luck.( still 5 ft 7" though
