It's only temporary. Low-carb diet is not a lifestyle diet.  It will inevitably lead the person to periodically binge on carbs due to chronic low energy and sugar cravings.  

I can agree with this.

A sustained diet that's high in fats, oils and animal protein will, inevitably, lead to diabetes, heart disease, stroke, hypertension and / or cancer.

I can agree with this also.  But Adkins doesn't promote the above; it's more moderate than you make it out to be.
I think for different people, since there are different body types, a lean-protein, moderate fat (15-20%) diet can work.  Most of those who practice Atkins and who are healthy, use protein powders and almost-no-fat proteins, so their fat intake is VERY low.  I don't see much of a problem with this, especially if they are athletes, since they need extra protein.

And you still haven't refuted the fact that refined sugar & white rice cures diabetes.

Well, it's one thing to reverse diabetes by using table sugar TEMPORARILY and QUITE ANOTHER THING to ingest table sugar LONG TERM.  Dr McDougall clearly states that table sugar has NO NUTRITIONAL value (which all of us should know) and will cause dangerous acids in the body which will rot teeth and cause other issues.  Again, you need to distinguish between table sugar and starches. 

Also, refined sugar & fruit won't rot teeth as long as the person practices regular dental hygiene. It's called brushing your teeth.

Dr McDougall is clearly promoting starches (potatoes, pasta, rice, beans, grains)!  He does not promote sugar (as is commonly understood to be soft drinks, cakes, cookies).  He's only arguing that sugar is not as dangerous as some of the oils we ingest (most of which are processed and from plants, like peanut, safflour, ect).  50 years ago, no society in the history of the world had the technology to mass-produce the dairy, cheeses and weird oils and protein we have today.  Moderation in everything, but we probably do eat too many fats.

Also, we have to distiguish between foods today and of 70 years ago.  Our great-grandparents were the healthiest generation in my opinion.  Those who were adults in 10s-30s mostly lived on farms and what did they eat?  Farm foods.  Milk, lots of starches, eggs, veggies, a little fruit, and healthy animals fats.  But the MAIN difference between then and now is NONE OF THIS FOOD WAS PROCESSED. 
- No pasteurized milk,
- No cows who were fed grain, but who ate WHAT GOD WANTED THEM TO - grass and herbs
- no egg whites,
- no chickens fed with grain, but who ate normally - worms, grass, bugs, herbs
- no GMO modified starches - corn, wheat, beans, grains, etc 
- no pesticide-soaked fruits/veggies
- no margarine or fake oils, but good 'ol butter from milk

When you compare our diet to that of 70-80 years ago, even if we're comparing eggs to eggs - IT'S NOT A FAIR COMPARISON.  Our food isn't even the same.  Farmland is nutritionally void; animals are fed grain instead of grass, animals are kept in cages, and fruits/veggies are soaked in chemicals.  Not to mention GMO issues.  It's a nightmare of epic proportions.

(on Intermittent Fasting) If you want to induce metabolic damage and, ultimately, weight gain, then have at it.

I listened to both of the videos (the 4 min one and the 70 min one).  In the first 12 minutes of the longer one, Dr M mentions that fasting is very healthy, but "we can't fast forever".  You don't even know what he preaches, which is very common-sense stuff.
 
The only new thing i've learned from him is his stance against fats.  This is interesting, which I will research more.

Using this logic, we can also say eating meat is bad because it's the result of original sin. Eating meat is a distortion of nature because true nature (nature in it's perfect form as God intended), which existed before sin, consisted of no killing of any creatures. Man, animals and the natural environment were in harmony with one another, and there was no need to kill for food, therefore there was no pain and death. Before the fall of man, it can be deduced that Adam & Eve's primary diet was carboydrate, and they lived off of fruits, vegetables and water, not meat. They did not kill animals for food, nor did animals prey on other animals for sustenance.

Isaias 11:6-10 tells us this true natural state will return when Jesus Christ returns to establish earth as part of the Heavenly Kingdom:

"The wolf shall dwell with the lamb: and the leopard shall lie down with the kid: the calf and the lion, and the sheep shall abide together, and a little child shall lead them. The calf and the bear shall feed: their young ones shall rest together: and the lion shall eat straw like the ox. And the sucking child shall play on the hole of the asp: and the weaned child shall thrust his hand into the den of the basilisk. They shall not hurt, nor shall they kill in all my holy mountain, for the earth is filled with the knowledge of the Lord, as the covering waters of the sea. In that day the root of Jesse, who standeth for an ensign of the people, him the Gentiles shall beseech, and his sepulchre shall be glorious." ~ Isaias 11:6-10



I stopped reading at the part it said "sugar causes insulin resistance". This is patently false as docuмented by the medical journals referenced by Dr. McDougall in the OP. Sugar causes insulin sensitivity. Also, judging by the face of the writer of the article, he is a soft body and he has too many layers of fatty deposit preventing optimal health. Apparently, his low sugar diet doesn't work for him. The scale and body fat percentage doesn't lie. Judge the efficacy of what is promulgated by the actual health & fitness of the promulgator, not by what he says...

You lose, again.

BUMP

"Dr McDougall clearly states that table sugar has NO NUTRITIONAL value (which all of us should know) and will cause dangerous acids in the body which will rot teeth and cause other issues.  Again, you need to distinguish between table sugar and starches."

BUMP.
...still haven't addressed the above...

Red herring fallacy, yet I have already addressed those subjects several times over.

Contrary studies are cited in the article.  Read the links in the footnotes.  Fact that you just "stopped reading" when you encountered something you didn't like tells me all I need to know.

The fact that you ignore the medical journals stating that table sugar and white rice cures diabetes, and fats and oils cause diabetes, tells me all I need to know.

Your "studies" are from modern "science" involved in many *fraudulent studies. Your studies are sponsored by the meat and dairy industry.

* read the various scientific journals on the thread I created reporting on the high incidence of fraud in research:

** Matthew, your forum's format is jacked up. I tried hyperlinking the above link but it wanted to go into Ladislaus' quote. Plus, I have trouble quoting articles without jacking up the content.

I do sprinkle sugar on hot cereal but not rice or veg. :-)
