How Obesity Can Protect From Disease


Obesity is not widely considered a protective mechanism. Quite the opposite. It’s usually considered one of the causal factors of the metabolic syndrome and insulin resistance.

I think obesity is a marker of disease, but ultimately it serves to protect the body from the effects of hyperinsulinemia. Let me explain.

New Study: Even a Liberal 130 g/Day Low-Carb Diet Beats Calorie Restriction For Type 2 Diabetes

Even a very “liberal” low-carb diet with 130 grams of carbs per day still beats a calorie restricted diet for controlling blood glucose in type 2 diabetes. This according to a new study.

Clinical Nutrition Journal: A Randomized Controlled Trial of 130 G/Day Low-Carbohydrate Diet in Type 2 Diabetes with Poor Glycemic Control

The low-carb diet in the study, where the carb count didn’t even get close to a strict low-carb regimen, still lowered both HbA1c and BMI significantly more than calorie restriction did.

So what’s the lesson? Stop giving bad advice. Stop obsessing over calories. That is simply not helpful.

People with type 2 diabetes do better by instead avoiding foods that raise blood sugars, i.e. carbs. Period.

A Quick Guide to Ketogenic Diets

A ketogenic diet (keto) is a very low-carb diet, that turns the body into a fat-burning machine. It has many potential benefits for weight loss, health and performance. But there are also potential drawbacks and side effects.

A ketogenic diet is similar to other strict low-carb diets, like the Atkins diet or LCHF (low carb, high fat). These diets often end up being ketogenic more or less by accident. The main difference between strict LCHF and keto is that protein is restricted in the latter.

A keto diet is designed specifically to result in ketosis. It’s possible to measure and adapt to reach optimal ketone levels for health, weight loss, or for physical and mental performance.

On our brand new guide page you can learn all you need to do that.

The Big Fat Fix Movie Released Today!

The Big Fat Fix, the excellent new documentary about the failed low-fat ideas of the past and how to really get healthy, is now released.

The last word in the fight against dietary misinformation.
– Men’s Health
Both Donal O’Neill and Dr. Aseem Malhotra star in this film.

Donal is the brain behind the movie Cereal Killers which has been called “One of the top 10 movies that could change the world”, and Dr. Aseem is known as “a leading global voice in the fight against obesity.”

Now they’ve teamed up and the result is a great independent movie – financed via a successful Kickstarter campaign. I highly recommend it.

The movie goes way beyond the benefits of low-carb and high-fat diets, into other lifestyle factors that are also important for a long, happy, healthy life.

You can buy it for streaming ($4.99) or download here:

How Kevin Hall Tried to Kill the Insulin Hypothesis with Pure Spin

Kevin Hall, the senior NIH researcher recently published a paper in AJCN that has received a lot of media attention. He claims this study refutes the insulin hypothesis so completely that it is now ‘dead.’ That’s interesting, I thought, as I sat down to read the article.

It was therefore a little surprising to read this paper and realize that Hall’s conclusions were entirely his own opinion. He suffers so badly from confirmation bias that he may as well have written “My mind is already made up regarding the insulin hypothesis. Please do not confuse me with facts”.

Confirmation bias is a well-known psychological phenomenon whereby facts that agree with your pre-formed opinion are accepted as true and those that are not are ignored. All facts become filtered through this bias to confirm your previously held opinion. It’s also known as a closed mind.

So, let’s take a closer look at this paper and its claims. Continue Reading →


Is Sugar Toxic?

Is sugar toxic? Professor Robert Lustig is perhaps the number one enemy of Big Sugar. His famous YouTube video “Sugar: The Bitter Truth” has been watched more than 6 million times.

In that video Lustig calls sugar toxic. So is it? Of course Dr. Lustig has had quite some pushback on that. Could sugar really be toxic? Isn’t it natural and part of the human diet since like forever?

In this interview, professor Robert Lustig explains it all. Watch a segment from it above (transcript). The full 30 minute interview is available on our member site:
