2. Carbs Are Not Inherently Fattening
Some sources blame carbs for obesity, because they raise insulin levels.
They claim that carbs are the primary cause of obesity due to their effects on insulin and fat storage. In other words, that carbs are uniquely fattening, regardless of total calories.
The truth is, scientific evidence overwhelmingly rejects this hypothesis.
This argument is also at odds with indigenous groups like the Massas, Kitavans and Tarahumara Indians, as well as the pre-industrialized Thai, Taiwanese and the rest of Asia during the 20th century. These groups thrived on high-carb diets (3, 4, 5, 6, 7).
If carbs are fattening and harmful on their own, then these populations should not have been in good health with lean bodies.
Bottom Line: Many populations have thrived eating high-carb diets and remained in excellent health. This indicates that “carbs” per se are not inherently fattening.
