Considering the new 'rise of the planet of the apes' film, surely that first ape should be put in again at the end?

I would just like to point out that the reason why we have problems with obesity is because evolution did not have enough time to modify our instincts for a food-rich and sedentary lifestyle. Think about it - for millions of years, our ancestor's primary concern was finding food to eat. This changed about 50 years ago with the advent of factory farming, and the Green Revolution.

Suddenly food is cheap and plentiful. If you live in a developed nation, you essentially don't have to worry about food - even if you do not have a job. Our instincts do all in their power to guarantee that we eat as much food as we possibly can - our brain ignore's the stomache's "fullness" signal for about a half hour before it allows us to feel "full". It tells us to eat as much as we possibly can, for fear that we won't have another chance to eat for several days.

Yet we always have something to eat every day. This is less about human stupidity, IMO, and more about evolution's ability to adapt to the sudden changes brought about by human technology.

Good point, evolution has managed the planet quite nicely for 4billion years, but has no chance of keeping up with us now. Some kind of mass education / enlightenment policy is in order.

p.s. I am currently on a diet (again) Sad

I was at a talk given by a nutriotionist who thinks that sugar is the root of all evil: a few hundred years ago we simply couldn't eat as much sugar we do now (foraging for berries is inefficient, meat or bread are much better sources of food) and he said insulin spikes from eating sugar do you the most harm. He also said that sugar is probably responsible for cancer (!) when sugar reacts with DNA in your blood, etc., and I'm not sure I believe him that far. Some of his general tips were things like only eat things that your ancestors would recognise as food and try to eat foods with fewest ingredients, no ingredients you can't pronounce, etc.

I'm supposed to be running my first half marathon in seven weeks. Thanks to a dodgy ankle and being trapped in the office - I've been there a month now and I still don't have a security pass - I've not been getting out running enough and I'm too slow and too fat still :-/

'Only eat food where you recognise the ingredients. Don't eat things we weren't really meant to eat i.e. large amounts of meat, lots of sugar, heavily processed food.' - I think that is great advice, now if only I could follow it. Wink
