Really irritated by this documentary on obesity So yesterday, I was watching a BBC documentary about why we're getting fat - why obesity is becoming more prevalent. I stopped watching 15 minutes in. A small fat geneticist (BMI:27, Body fat 28%) lectures us all on how it's the genetics that are affecting these people. I have never been more irritated. Yes. Genes can mean you are predisposed to obesity - heck, I'm predisposed to obesity. But I am not obese, I have a normal BMI of 20 -  a body fat of 18%. BECAUSE I LOOK AFTER MY BODY. I eat well, I exercise. And even being genetically predisposed does not magically mean 4000 calories worth of food magically floats into my mouth every day.  Genetic predisposition is a thing. But fatties using it as an excuse pisses me off. I'm in med school, and it really bothers me how we're exposed to treat these people kindly because it's their genes. I attended a communication workshop on it last week. Around 90% of the nurses are obese on the ward I work on, and I am constantly told off for inappropriate clothing - because I'm the only thinner one you can actually tell is a woman. And I know for a fact these women are prone to ordering thousands of calories worth of food to scoff down in their 10 minute break - but no. IT'S THEIR GENETICS.
