Health pundits blame the 'Western diet' for fueling the international rise in obesity and the consequent health problems. This is not true.

I live in the West. I do almost all my own food shopping. I choose what I eat and do. The result is that I am not obese and I am very fit.

For my previous obsesity I blame myself. Thirty years ago, when I weighed fifty pounds more than I do now, and was constantly tired and sweaty. I was repeatedly bingeing on refined carbohydrates – sugar and white flour. Nowadays I do not eat them at all.

Through what I believe is my geneticly induced eating disorder, the first bite of these substances leads me to crave for more. So I do not eat them. For the same reason I do not drink alcohol.

By working the Twelve Step program each day, I am at peace with myself and the world in general and my weight does not change.

All this – apart from my genetics – is my own choice. I can not blame the government or the shops for what I put into my own mouth. Nor can I blame food companies or advertisers or restaurants. I myself am totally responsible for my body weight and shape.

Through osteoporosis – another genetic gift from my mother – I am now six and a half inches shorter than I used to be. My collapsing spiral curves me into a stoop. So what? I take ten minutes of static exercise every morning when I get out of bed and I walk up seventy seven stairs – sufficient to get me out of breath – three times every day. I never waste time and money on a gym or pool or personal trainer.

As a result of these daily commitments to myself, I am fit and healthy. The eating and exercising habits of other Westerners have no influence on me whatever.

The basic problem in Western society – and increasingly elsewhere – is the belief that someone other than ourselves is responsible for everything about us. I do not believe that. I alone am responsible for what I choose to do.

As a direct result of my choices leading me to be in good physical, mental and emotional shape, I have a really lovely life. If other people want to blame Western diets or governments, or anything or anyone else, that's up to them.
