I have copied and pasted the main body of the article. If you click on the link and go to the full text, you will see that following the portion I have posted there is a long list of responses a rebuttals. It IS an interesting theory and it was touched upon in one of the discussions in the healthier eating/weight loss program that I attended at the VA Hospital. Insulin resistance is a very real medical condition and the theories and rebuttals included here make for some very interesting reading to say the least, but leave me somewhat confused. Thankfully I have cut way back on my red meat consumption anyway.
The pathways to diabetes
He suggests three pathways by which animal fat enters muscle cells: 1) Protein intake raises insulin, which in turn weakens the ability of muscle cells to keep out fat. Fat enters the cells. 2) A high protein diet is acidic. To keep its pH level balanced, the body extracts calcium from muscle cells, which causes these cells to waste, making them vulnerable to fat depositions. 3) Microbes contained in meat emit endotoxins that become embedded in the meat’s protein. When we digest the meat, its saturated fat shuttles the endotoxins into our blood stream, causing inflammation. This state of inflammation enables fat to enter muscle cells. Here’s what comes next:
Once fat gets inside the muscle cells, it interferes with that cell’s ability to develop new insulin receptors. With fewer insulin receptors it becomes more difficult to get sugar into the cell for processing, causing the sugar to build up in the blood. The pancreas then has to churn out even more insulin just to get the sugar into the cells. The very high insulin, which is not normal, will cause even more fat to enter the cells in a vicious cycle.
And so we become insulin resistant. Those remarks must set off Dr. Robert Lustig, a well-known and respected endocrinologist of the University of California at San Francisco. He has famously lectured on the dangers of sugar and its link to diabetes – in fact, you can some of his ideas in my blog post ”The Secrets of Sugar.” So be on the lookout for his rebuttal.
And how is Davis’ health? Several years ago he overhauled his diet. Out with the animal products, in with the plants. Once a sickly and, he says, slightly chubby man, he became a prize-winning ironman triathlete. Davis appears to be exceedingly well. And he has carried the lessons he learned into his practice. Take a look at this 2014 video, in which he can be seen with Houston’s very own Fully Raw Kristina, prescribing fruits and veggies:
This leaves us with the question who really is to blame for diabetes: sugar or animal fat and protein? I can’t tell. Perhaps one amplifies the other’s negative effects, making both responsible. I certainly look forward to Professor Lustig’s reply to the book. Few things are more interesting than seeing two highly regarded health experts debate their theories. In the meantime, I’ll try to keep my distance from both refined starches and animal products. Perhaps you will, too.
Notes
His diet consisted of 40 percent protein, 30 percent complex carbohydrates and 30 percent fats.
