Ah - there's nothing like a convert for preaching! Just like the ex-smokers are the most evangelical about the evils of their former habit, this post preaches the wonders of losing weight, in terms that only a former overweight person could.
While I take note of your message about the pointlessness of buying carbon fibre parts if you weigh more than a large teaspoon, and I even agree with it, I'm afraid I do take offence at your references to "your chubby little button", the "spikes in insulin", "plain dangerous" and the assumptions that I am short and 100 pounds overweight with severe health problems. Perhaps you don't write it to be mean, but I can guarantee that, reformed or not, anyone who does have weight problems would view your comments as extremely hurtful. The fact that you were once overweight yourself does NOT give you the mandate to insult anyone whom you believe to be overweight now. I know there's a tendency in some parts of the US to allow such rudeness, but in the UK it is still extremely bad form. Fortunately I'm nowhere near the chubby, slobbering couch accoutrement that you seem to believe I am. I'm a good deal taller than you imagine and virtually all the extra weight is muscle. This is not my naive assumption - it is the opinion of my doctors, dietician and physiotherapists, not to mention my rowing coaches and sprint cycling peleton.
Perhaps you don't have healthy, fit people in America, but I doubt it. I reckon you've even seen some. If not, have a look at the British Olympic rowing team at the Sydney Olympics and tell me that Sir Steve Redgrave is "chubby", that his weight is "plain dangerous" and that he is ten times as likely to suffer from your exhaustive list of complaints. I don't reckon you would want to suggest to him that he should lose some weight. He weighs more than me.
If I start to suffer from sleep apnoea, shortness of breath, severe heartburn then I might start to think that there's a problem. Until then, I'll live with my low cholesterol, low blood pressure and carry on rowing, cycling and swimming.
I don't write this to be mean. I simply know that you made a huge assumption based on one piece of data, and used it to be offensive without the remotest clue about whom you're talking to. If you remember nothing else from this, remember not to make assumptions.
Wishing you the best in your newly-discovered thinness (and I do mean that),
Sebowyer.
