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.
quote:
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.
