What Causes Obesity? More Science Points to the Brain

Michael Smith struggled with obesity and uncontrollable food cravings for much of his life, as he felt unable to resist unhealthy food despite knowing he should be full. It is mentioned that obesity is often misunderstood and a stubborn condition that doctors have only recently recognized as a disease, with a variety of potential contributing factors. New brain-based therapies offer hope for patients, even though they are controversial. Studies suggest that people with obesity may have broken gut-brain pathways and impaired brain circuits, influencing their eating behaviors. Genetics may play a role in obesity, yet the food supply of ultra-processed foods has also been identified as a major factor.
