- The current obesity epidemic has occurred due to modern dietary patterns characterised by excessive consumption of foods with a high glycemic load.
- Instead, much of the blame for the current obesity epidemic lies on modern dietary patterns characterised by excessive consumption of foods with a high glycemic load: in particular, processed, rapidly digestible carbohydrates.
- These foods cause hormonal responses that fundamentally change our metabolism, driving fat storage, weight gain, and obesity.
- The USDA’s Dietary Guidelines for Americans 2020 – 2025 further tells us that losing weight “requires adults to reduce the number of calories they get from foods and beverages and increase the amount expended through physical activity.
- ” 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.

- The study points to fundamental flaws in the energy balance model, arguing that an alternate model, the carbohydrate-insulin model, better explains obesity and weight gain.
