Only watched it for 5 minutes, I'm sure you are right, he had a decent first response. 'Like most on the left of politics...' Nice generalisation Col.
Elsewhere, the government's top obesity advisor (the fat Tsar?) has said that obese people should not be blamed for being obese because they are genetically programmed to eat too much and food is easily available to them. Even if this is true, which it may be I'm not a scientist, does it also mean they have to eat crisps and chocolate rather than more healthy stuff? I've been to supermarkets, they seem to have an array of stuff on offer. But the psychology of this is very interesting, where craving (and obesity is obviously an addiction, and a particularly dull one at that) overcomes fear of the consequences. Where this woman is definitely wrong in my experience is saying that 'it takes a superhuman effort of willpower to reduce food intake'. No it doesn't. I have very poor willpower but, motivated by fear, I have changed my diet entirely over the last few months (not specifically to lose weight). It's been easy, I'm never hungry and I feel much better, and still eat and drink very tasty stuff. It's just about substituting habits. Have a banana instead of 5 biscuits.
And even if the Fat Tsar is right, surely telling people that 'there's nothing you can do about it' will just make them feel worse?
