Protein diet to help in obesity fight by making us less hungry
High-protein diets have led scientists to a new hunger suppressant that could help fight obesity.
Phenylalanine, a component of dietary protein, reduces food intake by affecting the release of appetite-regulating hormones in the gut, research has shown.
It may be the reason why diets that involve eating a lot of protein can be successful at promoting weight loss, experts believe.
Scientists at Imperial College London studied the brain activity and eating habits of mice treated with phenylalanine and found it reduced food intake even at a dose 10 times lower than would be consumed daily as part of a high-protein diet.
The amino acid also increased activation of an area of the brain known to be involved in regulating appetite.
Lead researcher Mariana Norton said: "Understanding how food is detected in the gut may help to identify ways of treating or preventing obesity."
