In a recent blog post about the Global Nutrition Transition, we discussed that the transition towards ultra-processed foods is strongly and consistently associated with increased rates of obesity in populations all around the world. We are expanding on this discussion in this post by sharing evidence that ultra-processed foods are not just associated with higher calorie intake and body weight, but may actually cause overeating and weight gain. We are also discussing concrete steps – based on this research – that may prevent overeating and weight gain.
