This approach to weight management is based on the century-old energy balance model which states that weight gain is caused by consuming more energy than we expend.
In today’s world, surrounded by highly palatable, heavily marketed, cheap processed foods, it’s easy for people to eat more calories than they need, an imbalance that is further exacerbated by today’s sedentary lifestyles.
By this thinking, overeating, coupled with insufficient physical activity, is driving the obesity epidemic.
In contrast to the energy balance model, the carbohydrate-insulin model makes a bold claim: overeating isn’t the main cause of obesity.
Instead, the carbohydrate-insulin model lays much of the blame for the current obesity epidemic on modern dietary patterns characterized by excessive consumption of foods with a high glycemic load.
In particular, processed, rapidly digestible carbohydrates, cause hormonal responses that fundamentally change our metabolism, driving fat storage, weight gain, and obesity.
