Conclusion is that our increased intake of fructose (which is almost exclusively metabolised in the liver, and thus doesn't trigger the normal satiety mechanisms, is responsible for people over eating and feeling lethargic. The use of large amounts of refined sugar to replace fat in processed foods seems to track the rise in obesity...
Because fructose is detoxified in the liver in much the same way as alcohol is, I for one am going to cut down my intake of fructose so that I can increase my intake of alcohol!
Yeah, if you read the transcript it says that actual fruit is fine because it's so high in fibre that you can't overdose on it. Fruit juice is another matter, especially if it's been filtered.
As for the "get off the couch and exercise", it shows that your brain is tricked into thinking that it's starving because it doesn't detect fructose the same way as it does glucose. If you have a high glucose meal you feel super-energetic (which makes exercise easy and natural), and almost all of your tissues, including your muscles can take up and use glucose as energy. If you have a high fructose meal, you feel sluggish, your liver gets overloaded, and you just end up storing it all as fat, and feeling like sh!t.
On the apple thing I was being a smarty. BTW I was enjoying a red one at the time.
One thing I noticed when I started exercising seriously was that the exercise regime started driving my food choices - I was at first unconsciously and later consciously going for apples, bananas etc over other snack options, and cut out all soft drinks. It was water, coffee or beer.
fructose is sweeter than glucose, so companies can use less in their products than by just using glucose... One good example is chocolate... When chocolate is old and you get that grey appearance on the surface, that is fructose crystalising on the surface...
I freely admit that I was Very Very Drunk....
"They speak of my drinking, but never consider my thirst."
I read the article in full on the train home this evening. It pointed out the triple benefit of exercise, and also why the Atkins diet may have worked; people on Atkins noted that they ate less but couldn't tell why. A lot of people struggling with their weight tend to overlook the calories they drink.
