The weight loss research was published this week in the American Journal of Clinical Nutrition and indicates the diet message of ‘moving more and eating less’ has doomed diet efforts and may have even led to widespread obesity.
“But predictable biological responses oppose weight loss, including decreased metabolic rate and elevated hunger.”
Instead, those seeking to lose weight should focus on the hormonal response to certain macronutrients, the authors found.
By examining multiple studies, they found that when high glycemic index foods – carbohydrates that cause a rapid increase in blood sugar – are consumed, the body responds hormonally. It both increases insulin, a hormone used to direct sugar into the cells, and suppresses glucagon, a hormone used to release stored glucose when levels are too low.
“This all occurs in the absence of counting calories or eating less.”
