You can get Matt’s advice on fixing the metabolism for free by reading most of his many blogs.

I wonder if the Blood type diet theory is important to which diet you should eat. Type O blood is the caveman blood type. Cavemen probably ate a low carb diet from late winter to mid summer. Using Matt Stone’s theory the low carb diet would cause high levels adrenalin for long periods of time. The caveman is adapted to high levels of adrenaline.

People with Type A are people who have adapted to a high starch agricultural diet. Type A people digest starch better and digest protein less well than type O people.

I would expect type O people to do well on a low carb diet over the long term. I suspect Matt Stone’s people are Type A. Matt Stone talks about the low carb honeymoon, when the low carb diet causes an improvement in health. The honeymoon sometimes last as little as a few months. The honeymoon is caused by the increased adrenaline from the low carb diet. The honey moon ends as the body decreases its adrenaline receptors.

Anyone who plays knowledge like a Nigerian fraudster loses all credibility with me. “I have a fantastic eating opportunity for you!”

Hearing all sides was the reason I asked him to write a post. I don’t endorse his theories and still disagree with much of what he believes because of my own experiences, but I also don’t want to assume I have all the answers.

Another person talks keeps mentioning “oils.” Wonder what those could be? In other stories, the person specifies what he cut out, but not specifically what he ate. Just saying “meat” doesn’t tell you much. Most consumed dairy–some do fine with it, but that’s not always a recipe for success.

And when specifics as to the diet were given, it was clear that something was always lacking–SATURATED FAT. One guy who got sick over time was subsisting on beef jerky. Well, duh! Not much fat there. Most of these people were slowly succumbing to rabbit starvation. And in most of the stories, when saturated fat was added, health actually improved. Matt seems to have overlooked this and through his bias, has decided that added carbs were the reason for success. Matt, himself, never details what he ate. That makes me
suspicious.

He also doesn’t go into detail about the diet of the mountain Pima. Obviously they don’t eat refined carbs. But he tags on “game meats” at the end of the list of carbohydrates almost as an afterthought. I’d lay bets they get plenty of saturated fat in their diets, which more than likely explains their good health.

It is well-known that fructose does not spike insulin, but rather is broken down into fatty acids in the liver. But fructose is never injested by itself. It is always accompanied by glucose, whether in fruit, HFCS, or sucrose. People consume fructose/glucose in much larger amounts than the glucose that results from the breakdown of natural starches. So it’s easy to blame fructose by association, but it’s really huge amounts of accompanying glucose, which yes, cause insulin resistance, and deterioration of health. And the fatty acids from the breakdown of fructose will be stored as fat, even if all the
accompanying glucose is burned for fuel, so weight gain will be faster and more pronounced than if simply eating natural starches.

Also Matt praises pizza as one of his favorite carbs. That crust is made from refined white flour–not much natural starch going on there. And the rest is cheese and tomato sauce. Be interesting to see the effect of all those nightshades he consumes (tomatoes, potatoes) on his health over time.

Matt also claims to be able to heal your metabolism, but it’s a secret and you must pay him to find out how. While I have no problem with his making profit, in my mind this would not characterize him as a researcher, but rather an opportunist.

I’m not convinced starches are necessary, even if (perhaps) they’re not the cause of insulin resistance. There may be other negative effects besides insulin resistance. Cancer, for example, apparently feeds on glucose — not fructose, but glucose.

Nonetheless, I thought Matt’s ideas should be tossed into the mix. I don’t want to limit the discussion to people who agree with me, so I asked him to write a guest post specifically to point out where we disagree.

Found this article today which you may find interesting:

“Is Fructose the Sugar of Satan?”

I’ll give it a read.

The only carbs that I can eat in larger volume that don’t give me pain and bloating right away, are green veg.

Yup, I think grains are bad news for many of us, whether or not starches cause insulin resistance.

I am naturally underweight. I have actually weighed less in the past on a high-carb vegetarian diet, than I have over the last three years as I have incorporated much more nutrient-dense foods and animal products. We’re talking a 5-7 lb difference here but that’s big for me because my weight has been the same for a decade. I think it’s because I had less muscle when I ate crap.

I still eat potatoes, sweet potatoes, and cruciferous vegetables in limited amounts but if I overdo it (more than 100 grams carbs during the day, or more than a few grams after 7pm at night) I know right away – from my sore gums, migraine, and 10-hour marathon sleep sessions where I awaken with my face and hands visibly swollen from carb bloat…

Carbs in general seem to have such an extreme effect on me, even though I am insulin sensitive and from a long line of thin people.

It’s not actually natural for humans to eat wheat. Nobody living in a natural environment would grab a wheat stalk and eat it. It has to be pounded and processed because humans don’t have two-chambered stomachs (like birds) to break down the grains. Consequently, many people have never adapted to grains biologically and don’t do well eating them; they’ll get leaky gut syndrome, auto-immune reactions, etc.

I included it in a post awhile back. Good stuff.
