It’s my belief that sugar is the primary cause of health problems for Americans, followed by other, more complex carbohydrates, followed by abundance of Omega 6 fatty acids. Everything else is either secondary, or unimportant in creating a model that describes the relationship between diet and health outcomes.
The thought goes that muscle (and other) cells in the body become resistant to insulin, because insulin always tends to deliver sugar. Cells don’t want sugar, and therefore become resistant to insulin. Have you taken a look at the number of foods that have sugar, even when you don’t expect it? It’s like everything…
I don’t believe meats and other fatty foods are the cause of obesity in America; in fact, I think that in the absence of carbohydrates, it’s actually quite difficult to even gain weight, let alone become obese; the implication is that calories-in-calories-out as a model for weight change is complete garbage.
Gary Taubes describes this quite wonderfully in his books “Good Calories, Bad Calories” and “Why We Get Fat”, but the $0.05 version is that insulin (produced in excess when consuming sugar) causes the enzyme LPL to uptake fat into fat cells, and suppresses enzymes like HSL to break glycerol bonds in triglycerides that are stored in fat cells; therefore, fat goes into fat cells, and stays there.
When we drastically cut carbohydrates, the pancreas secretes less insulin, and allows us to metabolize fats (instead of sugar and glycogen).
So go ahead and eat that turkey and ham…but skip the potatoes and try not to overdo it on the dessert.
