Is Obesity Caused by Too Much Insulin?

Is Obesity Caused by Too Much Insulin? – Dr. Ted Naiman4.8 out of 5 stars5 star88%4 star7%3 star4%2 star0%1 star0%67 ratings6725:27


Is obesity mainly caused by the fat storing hormone insulin? And if so, why do many people still not agree at all?

As the dogma of Calories In, Calories Out is becoming more and more outdated, people like Dr. Ted Naiman sees tremendous results doing the opposite: Stop counting calories.

So what should you be doing if you want to lose weight? Dr. Naiman has the answer: Focus on lowering your insulin levels. And he shares the most effective ways to do it (low carb is just one of several important things).

As a practicing physician, Dr. Ted Naiman helps people find strategies that actually work and ways to improve your insulin sensitivity. In our interview, he explains what to do if you want to lose weight.

Why the First Law of Thermodynamics Is Utterly Irrelevant

There are many adherents to the Calories In/ Calories Out (CICO) theory that constantly bleat about “It all comes down to the First Law of Thermodynamics”. The First Law of Thermodynamics refers to a law of physics where energy cannot be created or destroyed in a closed system and is ALWAYS true.

However, in the complex world of human physiology, it is true but completely irrelevant. What the CICO people think it means is that if you reduce calories in, you will lose weight. Of course, it means nothing of the sort.

So, let’s see why. Continue Reading →

How to Fix Your Broken Metabolism by Doing the Exact Opposite

gc

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

david-ludwig-obesity-diets

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

bl

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 →
