Leptin and Insulin Resistance
Percy writes:

The big question is why western civilization is plagued with obesity, diabetes and heart disease. When people are removed from their South Pacific island or from the jungle or from whatever was their native habitat and are placed into western civilization, they find themselves getting diabetic and fat at about the same rate as everyone else on western diets. What's the cause? For 50 years the answer has been dietary fat. And in that 50 years we've gotten fatter and more diabetic. Taubes believes it's because the cause is not dietary fat, it's carbohydrates.

And now let me introduce another author of another book into the discussion: Dr.Ron Rosedale.Dr. Rosedale was founder of the Rosedale Center, co-founder of the Colorado Center for Metabolic Medicine (Boulder, CO) and founder of the Carolina Center of Metabolic Medicine (Asheville, NC). Through these centers, he has helped hundreds suffering from so-called incurable diseases to regain their health. One of Dr. Rosedale’s life goals is to wipe out type II diabetes in this country as a model for the world.

Rosedale has a theory that the body becomes resistant to Leptin, which coincides with insulin resistance and is a result of the societal shift towards refined carbohydrates and sugar over the last 100 years or so coupled with a decrease in physical activity.

You can read a summation of his philosophy here.

Basically, Rosedale argues that our primary fuel should be fat (good fat) rather than sugar and carbohydrates except for hi fiber lo glycemic carbohydrates such as broccoli, kale, and spinich.

He is against Atkins primarily because the protein levels are too high and because Atkins does not differentiate between good and bad fats.

To summarize, normally leptin, secreted acutely in response to a meal or chronically in response to increasing fat stores, in a leptin-sensitive individual, will reduce hunger, increase fat burning and reduce fat storage.

However, when one is leptin-resistant -- as indicated by an elevation in fasting serum leptin -- the part of leptin's message that would normally reduce hunger and fat stores and increase fat burning does not get through to the brain (here mimicking low leptin), so one stays hungry and stores more fat, rather than burning it. However, the message to increase sympathetic nervous system activity gets through all too loudly and clearly, so one stays hungry, continues to get fat, and gets elevated sugar, insulin resistance, high blood pressure, heart disease and accelerated aging.

Personally, the jury is still out on whether or not Rosedale is on to something. I am reading up more on Leptin.

Fat versus Carbohydrates
Percy writes:

Taubes provides no diet advice, but he believes elevated intake levels of refined carbohydrates in western societies are responsible for the obesity epidemic. Although Taubes argues his position from a scientific basis, from a purely practical diet standpoint the advantage of a low carbohydrate diet is that it results in much less hunger than other diets and is therefore easier to maintain. His other claim, that you can consume more calories on a low carbohydrate diet and still lose weight, has not been scientifically proven or disproven at this point in time.

The Rosedale diet is simply this:

* Avoid most starchy carbs and sugars.
* Eat good fats rather than saturated or trans-fats.
* Eat the 'right' amount of protein.
* Eat slowly and don't eat 3 hours before bedtime.
* Eat when you are hungry (rather than counting carbs/calories).
* It is effectively a high fat, low nonfibrous carb, moderate/low protein diet.

On a low carbohydrate diet, you are not as hungry as on a high carbohydrate diet if half of your caloric intake is composed of good fats, such as almonds, walnuts, pecans, olive oil, etc..

Rosedale also warns about overdoing protein.

Re: Triggers for Fat Storage or Use

One size doesn't fit all. Some people do better with more carbs and some do better with more protein.

I know for a fact that I am of the body type that thrives on moderate protein, higher "good" fats, and lo glycemic carbs.

As my body insulin goes down I become less resistant to the remaining insulin that I do have. As insulin decreases, glycogon increases. energy goes up and calorie expenditure goes up. weight drops at a steady rate for the first few months...and wont go back up as long as I function as a higher percentage fat burner and a lower percentage carb burner.

The trick is to not starve yourself from all carbohydrates and to be careful not to overdo the fat or protein intake.
