My BMI (Body Mass Index) is 25.2. Overweight starts at 25. So I’m now on a diet.

I like to claim that I have always been thin. Mostly that’s because I was thin for a very long time. But little by little I’ve progressed from not thin through normal through the higher end of normal and finally to being officially overweight at 64 years of age.

It’s clear to me that my idea of overweight is a non-event to most people. They can see that I’m heavier than I used to be but given the obesity epidemic and how big most everyone is becoming, it’s hardly a big deal. In fact I’m smaller than most of them. Not my wife however, who is slim, well proportioned and watches her weight like a hawk. But, hey, 25.2 is hardly overweight at all. Right?

Actually I don’t care about my weight. Never have. However, I do care about the fact that 100% of the extra weight I’ve added over the last few years has gone to my belly. I’m still fairly slim everywhere else. So I look a bit like a snake who’s eaten a beach ball and is having trouble digesting it. The fact that belly fat is particularly unhealthy, according to various magazines that want to make women feel better about their bum fat, doesn’t help. I also don’t want to upsize my clothes. And my wife wants me to lose weight, which trumps my other judgements.

So today I started a diet. It includes exercise (I walked 5km this morning, did a half hour beach walk and an hour and a half yoga class – do you think I’m overdoing it?), and no carbs. I have no great belief in a low carb diet – it’s just one of the hundreds of diets out there. I chose it because I have low iron so thought a diet with lots of meat would be a good idea.

I’m convinced that any and every diet works if you stick to it. If you restrict your calories and increase your exercise you’ll lose weight. I’m also convinced that diets almost never work. 95% of dieters regain what they lost within a year. So I’m wondering what to do after I lose the weight. Some people keep it off. How do I become one of those people?

I know. I’ll watch my wife. See what she does, and do that. That’ll work.
