America’s Obesity Epidemic
Over the past 30+ years, America has developed a bit of a weight problem.
And during that time, just about every doctor, scientist and snake oil salesman “discovered” the cause of and the cure for America’s obesity epidemic.
If it wasn’t too many calories, it was too much fat or too many carbs.
So…who was right?
Carbohydrates and the Obesity Epidemic
According to this examination of the National Health and Nutrition Examination Survey, we can officially blame America’s obesity problem on our increased consumption of calories from carbohydrates.
As you can see above, American levels of obesity skyrocketed during the years between 1975 and 2006.
What you don’t see is why. For the why…look below.
As you can see in these graphs, the past few decades have seen a dramatic shift in the way that America eats.
Our macronutrient ratios have shifted to create an increasingly carb-centric diet.
Even as our total calories increased, we somehow managed to eat a growing percentage of those calories as carbs:
And as we know from previous research, sugar drives insulin and insulin drives obesity.
And if we don’t want to see American obesity levels rise even higher, perhaps we should pay attention to the science and:
- Decrease overall caloric intake…while specifically…
- Limiting our consumption of carbohydrates
