Agnostic of diet, increased calories can result in excessive body fat, what researchers call adiposity. EBM focuses on caloric intake, and attributes the recent growth in obesity to the changing food environment, which increasingly includes convenient, palatable, calorically dense foods, often in large portion sizes. The first model is the energy balance model. The model matters, because it informs our historical understanding of obesity, the biological mechanism at play, seeks to answer why it’s risen so sharply on a global scale, and directs the decisions of doctors, dietitians, and normal people about our food choices. Guyenet, an obesity researcher and author of The Hungry Brain, told GQ. There are many theoretical models of obesity, as Stephan J.

The other argues that there’s something particular about unhealthy food that causes the body to go haywire-specifically, that excessive consumption of carbohydrates breaks down the body’s ability to process sugar. One model of obesity emphasizes how much of these foods people tend to eat-how many calories-and the brain’s role in regulating that consumption. But there is a debate raging in the academic community about why, exactly, consuming these foods leads to excess bodyfat.

There’s also broad consensus about why it’s happening: the ever-increasing availability of industrially produced, ultra-processed foods. Nutritionists and researchers generally agree that obesity is rising sharply in the United States, and that it’s a big problem.
