You enjoy running, Chynah - not everyone does.
It depresses me when I come onto these threads and try to give an insight into me and my problems with food/weight etc, only to have someone come back on and basically say, 'it's easy - go for a run, don't eat the fattening food, you are wrong when you say that there are other factors in weight gain.'
At the most basic level, yes, I am overweight because my intake of calories has exceeded my energy usage over many, many years. But the question you don't seem to want to address, Chynah, is why I have done that.
I don't like myself. You don't take care of something you don't like - and I don't take care of myself. I have cripplingly low self-esteem, which is not helped by judgmental attitudes like some of the ones demonstrated on this thread. When I am doing the shopping list for the week, I don't plan in healthy lunches for myself - something deep inside me tells me I don't deserve to have that consideration for my needs - so I end up eating left overs or something on toast - not the best choice by any means.
Also, the antidepressants that I am on make me nauseous. I take them first thing in the morning (I can't take them at bed time, because they also caused disturbed sleep patterns), and this means I very rarely eat breakfast, so by mid to late morning, my blood sugar is plummeting, and then I crave something high in sugar or carbohydrate - not the best choice again. Plus, not having breakfast means my metabolism doesn't get that kick start in the morning.
It must be lovely to be slim, active and to enjoy exercise. I have never been any of these, and just living is an uphill battle. I wish you could live a day in my skin, and feel the self-loathing, the tiredness, the depression, the feeling that even thinking about an activity is like wading through treacle, never mind actually doing it. You might understand me a bit better then, and stop writing me off as stupid, in denial, lazy etc.
