Only if putting 5 stone on over 15 years is yoyoing.
Just to put your mind at rest.
At 18 I left home and immediately my staple diet was pizza, wine and beer. In 12 months I went to 17 stone from 13.
At 19 I got a job at a stables and with my money stopped drinking and the job was physical, this was my first weight loss.
At 23 I met my wife and settled into meals round the table and plenty of social drinking. I also got into a habit of finishing her plate for her. As my career progressed my jobs got less physical and I spent more time behind a desk.
As I am 6' 2" we didn't really notice the first few stone.
At 36,this year I got a job that means I spend several hours a day in the car. I made a decision that if I did not sort my weight out I would end up seeing my days out overweight.
Hence, a severe change in lifestyle.
Hope this clears any worries. I am a firm believer of doing what feels right and so far I feel great.
Probably just the fact that your body is getting used to the extra energy getting used up, BUT how much are you actually running? When I'm doing up to about 18 odd miles a week I don't really feel the need to eat any huge amount more than what I do normally, and I only ever eat 3 meals a day, no snacks, so perhaps what you need to do is eat slow burning food, more wholemeal things, so that you're fuller for longer. You must be careful with these things, you may feel like you should eat more because you're hungry more when you start out, but that's how a lot of people falter and end up not losing weight etc etc, because they actually end up eating too much.
