How to Fix Your Broken Metabolism by Doing the Exact Opposite


We saw recently with the Biggest Loser study that basal metabolism plummets when you lose weight with calorie reduction. As contestants lose weight, they burn a lot less energy – up to 800 calories per day less than before!

Some of that is expected, since there is less body tissue to maintain, but nevertheless, these contestants burn far less than expected even taking this into account. Even 6 years later, their basal metabolic rate (BMR) remains depressed, as do the contestants themselves.

The story got a lot of coverage, but one thing was consistently missing. How to fix it. That’s what I’ll show you today, and it’s the opposite of what most people expect. Continue Reading →


Defense of the Insulin-Carbohydrate Model Redux: A Response to Kevin Hall


Did the recent Kevin Hall study refute or strengthen the insulin–carbohydrate model of obesity? Here’s another excellent perspective, from Harvard nutrition professor Dr. David Ludwig.

Far from falsifying ICM, Hall’s study supports it. A more accurate summary than the one he gave at the abstract session might be as follows: “We found preliminary evidence for an exceptional effect of a very-low-carbohydrate diet on energy metabolism. This finding suggests that reducing carbohydrate may be advantageous to conventional approaches for weight loss maintenance…

The Right Weight To Live Longer

If you want to live a long life, what weight should you try to stay at?

There have been earlier talk about an “obesity paradox“, as overweight people seem to live longer than normal weight people in some studies. This despite the connection between obesity and diseases like cancer, heart disease etc.

The “obesity paradox” idea has been heavily criticized as a statistical mistake, due to things like smoking and many diseases lowering both weight and life expectancy.

A new large review of 230 studies including 30 million people try to correct for this problem. In healthy never smokers, in studies with longer follow-up, it seems that normal weight is clearly associated with longer lives.

In fact the people who live the longest have lived most of their lives at a BMI of about 20-22, or at least below 25.

Interestingly this also means living with low insulin throughout life.

The Biggest Loser FAIL and That Ketogenic Study Success


This week, splashed all over the New York Times, was an article about a paper written by Kevin Hall, a senior researcher at the National Institutes of Health. It was published in Obesity and titled “Persistent metabolic adaptation 6 years after ‘The Biggest Loser competition“. This generated a lot of hand-wringing about the futility of weight loss.

NYT: After ‘The Biggest Loser,’ Their Bodies Fought to Regain Weight

The study, along with another study presented by Kevin Hall seemed to generate more anxiety about the insulin hypothesis being dead. Of course, both these studies fit in perfectly with the hormonal view of obesity and reinforces once again the futility of following the Caloric Reduction as Primary approach. You could review my 50ish part series on Hormonal Obesity if you want a more in-depth view.

So, let’s dive in an explain the findings of both of Dr. Hall’s excellent papers. His conclusions, well, let’s just say I don’t agree with them. The studies, though, were very well done. Continue Reading →


The Diabetes Economy


[This is one of the first posts on this site by Dr. Jason Fung]

Insulin, first discovered in 1921, revolutionized the treatment of type 1 diabetes. Dr. Banting licensed insulin to pharmaceutical companies without a patent because he believed that this life saving drug for T1D should be made available to everybody who needed it.

So, why is insulin so hard to afford today? Continue Reading →


Hyperinsulinemia: Best Management Practice


High levels of the hormone insulin is a core problem for most people with obesity, as well as type 2 diabetes and high blood pressure. So how can it be treated?

Here’s a good new review paper on it, from Professor Grant Scofield and co-authors. In short the effective treatments come down to carbohydrate restriction (including fasting) and high-intensity exercise.

Is Your Weight Controlled by Calories or Insulin?

What really matters for weight loss? Calories in and calories out, or is our body weight carefully regulated by hormones, like the fat-storing hormone insulin?

In this presentation from the 2015 LCHF Conference in Cape Town I describe why the second explanation – about hormones – makes much more sense. And why the first one – about calories – is a simplistic description that completely fails to address the cause of obesity.

You can watch a segment above. For the full presentation you can buy access to the entire LCHF convention for $49 dollars from the organizers.

There’s a free option too – you can watch this presentation and more than a hundred interviews, video courses, other presentations and movies on our member site with a free trial.

No Weight Loss? Consume Less Dairy


Are you not losing weight? Here’s a tip that works well for many people: Try to consume less of dairy products.

The lactose and protein in dairy could be keeping you from losing weight. Dairy products contain varying amounts of lactose (the milk sugar), which slows down weight loss. What’s more, part of the protein in milk generates a significant insulin response, which can have the same effect.

Milk is originally for babies and this growth signal is perfect for them. For adults, it may just result in horizontal growth instead. And cutting back on dairy products can result in weight loss.

Definitely avoid all low-fat dairy products. They just tend to accentuate the potential problem. As the satiety effect of the fat is removed, people easily consume more of it instead.

Protein powder is pure milk protein. It may be helpful for building slightly more muscles, but people build their midsections at the same time.

Exempt from all these dairy-product warnings is butter, which is almost pure fat. Butter may be consumed liberally whenever hungry.
