@Apple1 you will love the book! Best 18 hours of my life. ;p And he's very aware and discusses known flaws in studies he reports on. Love that we know we're getting the best science.

I need to buy it as well, I know I'll enjoy it; I enjoy the website and that special he had on. Trying to finish up Proteinaholic though. Almost there!

This will be long. It'll be for those who are checking out the thread and those who just want to be reminded. It's a rant about Type II Diabetes from Dr Garth on his FB page some time back. LOL ENJOY READING!

So, this is going to be a long rant with lots of scientific references, reader beware. The cliff notes: carbs do not cause Type 2 diabetes, meat does! I will provide references at the end of the post.

"But wait a second" you may say. "My sugar goes up when I eat carbs, so carbs must be to blame". You are not alone in this thought. Even the President of The American Society of Bariatric Medicine thinks this way. He believes that if your sugars are low you are cured of diabetes. SO he puts people on low carb diets , and in fact the studies show low carb diets will lowers blood sugar, go figure. But has diabetes been cured? Are they healthier? Low carb studies are very short term and use lab results as their end points, not end organ disease. They don't prove that low carb diets reduce heart disease, they show that it raises HDL and since high HDL is associated with less heart disease they assume that heart disease is lower. Likewise, they assume diabetes is cured when blood sugar is low, but has diabetes been cured? Not at all. As soon as the patient eats a carb the blood sugar will rise. Why? Because they still have insulin resistance. So many people make the mistake of thinking diabetes is a disease of high blood sugar. High blood sugar is just a symptom, the disease is insulin resistance. This is why I see so many failed Atkins and Protein fast patients.

So what causes insulin resistance. This is the big question. Treating the symptom and not the cause is the typical western medicine paradigm. We need to look beyond. The fact is the biggest consumer of sugar, the organ most affected by insulin, are your muscles. I find it ridiculous that people, like Robert Lustig and Gary Taubes, talk about insulin as some kind of awful hormone. Why would we evolve to have an evil hormone that is in every single person. Insulin is only a problem when the body is resistant to insulin. Insulin serves a vital purpose, which is to get the fuel into the cells, and muscle needs glucose to generate fuel.

Our bodies are built to live off sugar. Insulin is supposed to join to an insulin receptor on the surface of the muscle cell which allows the sugar to enter the body and then be utilized to produce energy in the mitochondria. In fact, the healthiest people in the world eat tons of carbs. The Sardinians and the Okinawans eat 80% of their calories from starches and yet their insulin levels are not sky high, and their blood sugars are normal.

So what causes the muscle to become insulin resistant. Well this is a little more complex but it appears that it is fat build up in the muscle cell. Excess fat entering the cells interferes with the muscle cells ability to produce insulin receptors. If the muscle cannot make insulin receptors then sugar cannot get into the cell and then the sugar starts to build up in the system. Then the pancreas has to produce even more insulin to try and force sugar into the cells, and now you start getting high insulin levels. Moderate insulin is good but high insulin inhibits an enzyme called hormone sensitive lipase causing even more fat accumulation, and a vicious cycle begins.

This then begs the question, "what causes fat to accumulate in the muscle cell"? Well, there are many theories. One is that insulin combined with lipids in the blood stream after eating causes intramyocellular fat. This makes sense. So if you eat steak believe it or not your insulin rises. It is also filled with fat. The insulin will cause fat to be accumulated in the cell. The same thing would happen if you ate a donut or a pizza. These are not carbs. They have carbs but they actually have more fat than carbs.

Other theories are that inflammation causes the muscle cell to dysfunction and not oxidate fat, causing fat accumulation. There is definitely evidence that acid accumulation cause insulin resistance likely from muscle cell dysfunction. Type II diabetes has been rising at astounding rates. How does our diet differ? We are eating a very acidic diet with too little of the bicarbonate producing plants as our ancestors did! Meat based diets are very acidic and cause inflammation which results in intramyocellular fat. There are even models that show certain amino acids will cause direct deposit of fat in the muscle cells.

There is some fascinating research looking at MRI's of people's muscles which show that athletes are able to mobilize fat easily from their muscle but overweight people cannot. This raises the additional question as to whether exercise has an affect on intramyocellular fat.

There is also a good body of studies showing high Iron stores can affect insulin resistance. As you may know, meat is high in a particularly toxic form of iron which can further attribute to insulin resistance.

Interestingly, carbs are readily burned in our body or stored as glycogen. It is actually very difficult to turn carbs to fat. The only time carbs become fat is when glycogen stores are full and calorie intake has exceeded expenditure. A nutrition professor proved this by eating a high sugar diet but keeping calories less than 1800 calories. Despite eating almost purely sugar, he lost weight and his insulin resistance improved.

So if what I tell you is true then it should work in a randomized control trial and in epidemiologic studies of populations of people. In fact, it does. Dr. Turner-Mcgrievy and Dr. Barnard have put it to the test. They took diabetics and randomized to either vegan diet or the typical ADA, high protein diet recommended by doctors. Despite eating high carbs and lots of fruit, the vegan group had significantly greater drop in A1C.

We can see this in action in many different epidemiological studies too. The EPIC/Panacea study, which is the largest epidemiological study ever done on food and disease, found no correlation between carb consumption and development of diabetes, but meat had strong correlation to diabetes. In fact, fructose consumption was associated with less diabetes. This becomes more understandable when you know that meat causes inflammation, acidosis, stimulates insulin, and has fat.

People tend to think Type II diabetes is genetic, but diabetes is affecting all races at this point. In fact, Japanese had low rates of diabetes but if they migrated to Brazil, which is having a crisis of diabetes, they get very high rates of diabetes. In fact, the Brazil government has made recs to decrease meat. The same recs are being given by the Japanese government which has noted an increasing rate of diabetes with the increasing meat consumption.

One of the best long term studies is the Adventist Healthy study as they followed a large population for many years. The population was healthier in general due to lack of smoking and drinking and moderate exercise, making them an excellent study given less confounding factors. The vegans had considerably lower diabetes than the meat eaters.

Even Harvard's Nurses Health Study, which is the largest and longest epidemiologic study in America, shows a significant relationship between animal protein consumption and Type II DM formation.

Let me also add that the randomized control trials and epidemiological studies, unlike the low carb studies, show improvement in end organ function. Less heart disease, less kidney dysfunction, less neuropathy, and longer life.

Most of all. Let me tell you that it is absolutely ridiculous to eat less fruit, as the president of the American Society of Bariatric Medicine claimed at our meeting. Studies show that fruit consumption does NOT increase A1C and is actually associated with weight loss and diabetes control. Studies show increasing carbs actually controls diabetes if they are whole grains, fruits and veggies!

I like this, what Dr Davis sums up:

"Correlation doesn't equal causation." ...which translates to...."I don't want to accept the fact that thousands of published studies following tens of millions of people for dozens of years have found clear and dramatic linkages between eating animal Protein and developing cancer because you can't prove a direct causal link." ....by that criterion of proof, we can't prove that cigarettes are harmful. We can't even prove that shooting someone with a gun can kill them because sometimes people get shot and live."

LOL

Thank you posting this @Newme17. I can attest to this. Before surgery when I was eating low carb my BS would be good, but as soon as I ate any type of carby food it would rise high right away. My diabetes was not cured at all, I was just controlling it.

I love how well Dr. Davis explains this whole process and also posts his references. I hope those that are reading this thread, will benefit from this information.

I just found out that my brother and his wife decided to do a low carb-high fat diet???? (Hanging my head).....I'll be calling them to share some things. My mom of all people (who is a proteinaholic) did tell him that lowering his carbohydrates is dangerous. HAHA! Go figure. I'll send him a copy of the book.

But it is so hard to get people to understand this. For me a good point is that you have got nothing to lose, but everything to gain.

All you can do is try, maybe he will listen or maybe not.

My older brother is very stubborn. I have been trying to get him to quit smoking for years. I even bought him this ecig vape kit that many people use to kick the habit. He told me flat out that he doesn't want to quit and he knows it will probably kill him???

I actually just asked my other brother a question regarding my mom and her health (obesity, cancer, etc). I asked "why doesn't it seem like mom (or anyone else) doesn't want to do EVERYTHING possible, including going on a plant based diet, to combat cancer (be in better health)???" There's so much evidence to support it....I guess not everyone can be like me (or you).

Hope so. Too bad about your brother. I hope he changes before it's way too late. Did you see the special on PBS with Dr Greger? Or maybe it was a video I saw. It showed the lungs of smoker being healed basically (I don't remember percentages) from changing diet to plant based and obviously not smoking. It was fascinating. I'll have to find something on it.

I have read that your lungs start repairing themselves as soon as you quit. I am sure a healthy diet can only help. I pray he doesn't get lung cancer or copd. I am glad I never picked up that habit.

what would be interesting is to monitor muscle mass after a switch to a lower Protein diet. I do regular dexa scans and I have gained muscle (though I don' t work out) it is counter intuitive. but I chalk it up to my high protein intake. I plan to continue the dexa scans so if I drop my protein I'll let you know if it impacts muscle mass.

Where do you get the dexa scans? I want to get my BMR tested and I would love to get a dexa scan also.

just google dexa scans for your area. I found one close to home..usually costs $100 and well worth every penny

I'd like to know this too. Although I haven't had a dexa scan, and went to plant protein (obviously a lower protein count--if I were counting), my strength hasn't gotten lesser at all. If anything I feel it's getting stronger. I still do my weights and I'm still building my muscle on a WFPB...so, based on my experience, I don't believe that the high protein has much to do with how much muscle you put on. If anything, IMO it's a overdose of protein for the body that route. My husband is bodybuilding on a WFPB diet as well. He's lifting heavier each week and he's pretty surprised with it all. I surprised myself too last night...I usually lift about 60 pounds on triceps, but I did 80...and all my sets too! Whoo whoo!
