I've been yo-yo dieting for years also. My problem has never been that I eat too much - I'm not much of a foodie and don't binge. The problem has been that I don't do any exercise whatsoever. As a result I put on weight very gradually, just 1lb a month which is only an excess of 3500 cals a month, but doing that every month of the year soon adds up. I've always had the excuse of having a bad back for not doing any exercise and being overweight and it's true that pretty much everything hurts it, until I found cycling that is!
The yo-yo dieting had been getting harder and harder as the years go by. I was having to eat only 800 cals a day to lose any weight which was pretty miserable. I couldn't eat anything I wanted, drink any alcohol, eat out at all and felt sick with hunger 24/7. I started the latest diet in late May and despite a couple of hiccups along the way to do with a holiday and illness, I had lost a stone by the time the Olympics arrived in late July. It was a miserable start to the summer for me though and I knew something had to change.
I had thought about cycling for a long time but my only bike was an old knackered mountain bike that needed money and time spent on it to fix it up. However the Olympics inspired me to do just that and since then I have spent over an hour cycling each day. A couple of weeks ago I treated myself to a shiny new Triban 3 which has really made things a whole lot easier. At first the weight started to fall off at an alarming rate (if you lose more than 1-2 lb a week you will exacerbate the problem of loose skin) but now but I have upped my calorie intake to a much more reasonable 1500 cals a day and I am losing about 1.5 lbs a week, which is ideal for me. I no longer feel sick with hunger and no longer have trouble sleeping as a result of that either!
I'm going to post my progress here every month for a bit of extra motivation. Here it is so far:
Height 6' 2"
Start: May 28th - 15st 10 lbs
Started cycling: 5th August - 14st 11.8 lbs
12th Aug: 14st 10.2 lbs
19th Aug: 14st 9.0 lbs
26th Aug: 14st 7.8 lbs
2nd Sep: 14st 6.4 lbs
Goal 12-13 stone, not quite sure yet. I have also started to do weights and combined with the cycling I will build up some muscle so it depends how far I go with that.
