It's just amazing his beginning of speech. It took millions of years of evolution to get to where man was in 1985. Of course, it could be argued it took billions of years.
Probably not billions of years. Eukaryotic cells made their appearance less than 2 billion years ago. The first multicellular organism may have appeared less than a billion years ago.

And what now is taught as the solution? Eat more fat. Oil, butter eggs. From my vantage point, we have no hope.[/QUOTE]
Absolutely eat more eggs, fish, olive oil. And leafy veggies. It doesn't mean eat 3000 calories. Eating this way leaves you less hungry, more energetic and alert as well. I find I'm satisfied on 1300-1400 calories eating this way. Also, it is much easier to get one's essential fatty acids from this way of eating.
The problem is we were told to eat low fat, and the food industry is making a killing with all the high carb and high sugar junk foods. This was codified by the U.S. government in 1977-78 in the development of the nutrition guidelines that may have had a lot of input from the food industry. Carbohydrates, grains, sugars, are cheap to produce and are shelf stable. Add a little salt and sugar and you have a really addicting food. Potato chips. Crackers are salty and sweet. Sweet cereals. The same thing happened in the UK at the same time. And they UK also has a big obesity problem. Wherever the western diet is adopted, obesity soon follows.
Delve into the subject and one realizes that Gary Taubes, Stephen Phinney MD, Andreas Eenfeldt MD, and others, may really be onto something.
Actually, the point is to basically stop eating so many carbs. If you don't get your energy from carbohydrates, you have to get it from the other macronutrients. Your choices are: fats and protein. You need protein, but if you take in enough to metabolize your protein for energy, there will be an increase in insulin levels. And excess protein does not turn into muscle, and it isn't very good for your kidneys. So that leaves fat. And some saturated fat isn't all bad, and we used to think that polyunsaturated fat was good fat, but omega-6 PUFAs are not, so it seems it's best to get most of your fat from monunsaturated fats--olive oil for example. We have essential fatty acids and essential amino acids. There are no essential carbohydrates.
