“Obese Stomachs Tell Us Diets Are Doomed to Fail” – ScienceDaily
According to a new study, the nerves in the stomach that signal fullness to the brain become desensitized when a high-fat diet is consumed and significant weight is gained (obesity). Even if the diet is corrected and fat lost, the nerves won’t go back to normal.
This means more food would need to be consumed to reach the same level of fullness as someone who has always had a healthy diet. Researchers think this could be one of the main reasons why a lot of people who lose weight/fat on a diet eventually put it back on.
