00:00Imagine if your gut could tell your brain to stop eating, like a built-in Ozempic with zero side effects.
00:06Well, scientists at Duke University just discovered it can.
00:09Inside your colon, special gut bacteria release a protein called flagellin when you eat.
00:14That protein triggers a hormone called PYY, your body's natural I'm full signal.
00:20This signal travels through a newly discovered gut-to-brain pathway that works like a sixth sense.
00:25And when it works properly, it tells your brain to stop eating in real time.
00:29But when this system breaks down, the brain doesn't get the message, and people tend to overeat and gain weight.
00:36In mice, those with this natural sensor ate less and stayed lean.
00:40Those without it ate more and gained weight, even on the same diet.
00:44Scientists believe we can enhance this gut-brain connection with probiotics, prebiotics, or even diet tweaks.
00:50It's a natural way to control hunger, without the harsh side effects of drugs like Ozempic.
00:56Your gut might be smarter than we ever thought.
