Clinically and morbidly obese people do not need to hear more reasons why it is "ok to be fat". They need to know how to lose it and still maintain a reasonable and healthy lifestyle.
Everything in life is about balance. Too much (or too little) of anything and your life goes out of kilter.
There are people such as sportsman who need to be really lithe and lightweight like roadbikers, jockeys, racing drivers etc. Yet some sports and activities require a bit of 'timber' like professional sumo, rugby, power-lifters.
But I guarantee their weight is distributed differently to your average overnourished couch dweller, certainly not clustered around internal organs which does the most damage.
