Higher Energy Consumption Leads To Weight Gain

Higher Energy Consumption Leads To Weight Gain

Higher energy consumption leads to weight gain.  The latest perspective article challenges the 'energy balance model,' which demonstrates weight gain occurs because individuals consume more energy than they expend.

The Centers for Disease Control and Prevention (CDC) shows that more than 40% of American adults have obesity and are at higher risk for heart disease, stroke, type 2 diabetes, and certain types of cancer.

According to the  USDA's Dietary Guidelines for Americans 2020 – 2025, adults should reduce the number of calories, they get from foods and beverages to lose weight.

Now, a perspective article explains that obesity is a metabolic disorder driven by what we eat, rather than how much. This approach is based on the century-old energy balance model which shows that weight gain is caused by consuming more energy than we expend. 

The article is published in The American Journal of Clinical Nutrition. This perspective points out the carbohydrate-insulin model which better explains obesity and weight gain.

The latest approach notes that excessive consumption of foods with a high glycemic load: in particular, processed, rapidly digestible carbohydrates fundamentally change our metabolism, driving fat storage, weight gain, and obesity.

The article suggests that overeating isn't the main cause of obesity.

“To understand the obesity epidemic, we need to consider not only how much we're eating, but also how the foods we eat affect our hormones and metabolism. With its assertion that all calories are alike to the body, the energy balance model misses this critical piece of the puzzle,” the authors say.
