My Body Mass Index

About a decade ago I decided to lose some weight. I've always been overweight for my height - or undertall for my weight. I managed to reduce my weight slowly over a number of months by removing snacks & junk, and basic portion control. Combined with more exercise I managed to shed a quite a few kilos.

My diet and exercise regime has largely remained constant, I don't each too much junk and have plenty of fresh fruit and vegetables in my diet and in summer bike quite a bit. However overtime more snacks sneaked in, and portions started to grow again. While I wasn't as heavy as I was a decade ago, I was definetly heavier than I should be.

While I'm still highly dubious of the Body Mass Index (BMI), it being based on flawed maths, I clearly need to target a much lower weight than the last time I reduce my mass. The BMI suggests about 65 kg for my height (1.7 m), and at the moment I'm 83.5 kg and falling by a target rate of about 100 g per day. If I stay on track that's about 26 weeks on my current diet before I tweak it to level off.

So far I've stuck a pretty even rate of about 111 g per day, and I've only had one period of food cravings, after a bike ride on an empty stomach - which was to be expected - and was satisfied with an some fruit and a drink of water.

I've also managed to drop a trouser size, going from 91.5 cm being tight, through being loose, to 86.5 cm being wearable if a little tight after a meal. According to the height to waist theory - which has better science behind it than the BMI - I should aim to wear 81.5 cm trousers and they should be loose.
