Check out this incredible report emphasising the flaws of our beloved Food Guide Pyramid. In the report from Nutrition Journal, we see how explicitly invalid our current recommendations are.

Through the years there has been ample evidence of a low carbohydrate diet (with consistent calories) providing weight loss, while calorie restriction alone doesn't necessarily provide body fat loss as well. Read the report to see more details.

In the three decades since, carbohydrate consumption has increased; overall fat, saturated fat, and cholesterol consumption have decreased to near or below targeted levels; caloric intake remains within recommended levels; and leisure-time physical activity has increased slightly (pp. D1-1, D3-10, B2-3). At the same time, scientific evidence in favor of these recommendations remains inconclusive, and we must consider the possibility that the “potential for harmful effects” has in fact been realized. Notably, “the prevalence of overweight and obesity in the US has increased dramatically in the past three decades” (A4); the number of Americans diagnosed with T2D has tripled.

Thanks to Mark Sisson and his reader Eric for finding it.
