Seems like I’ve read this so many times in so many places. It takes 20 minutes to feel full, for your stomach to signal your brain that you’re full and time to stop eating.
I find this hard to believe. I can feel full way before 20 minutes, granted I eat faster than the average person. Haven’t ever eaten a huge burrito or plate of pasta and by the time you’re done, 5 minutes later, you can’t move, lying there beached like a whale. Do i have really fast signals from tummy to cranium, or is this just hogwash tyrying to make you slow down when eating.
That’s true now that you mention it. I had always bought the “X minutes before you feel full” bit but you just made me remember going out to lunch last week. I was struggling to finish a huge Pad Thai and had to decide which bits to leave uneaten so it was no minutes until I felt full.
I think there are a number of factors to the thing; there is the simple mechanical sensation of your stomach straining near to bursting point, but there’s also the chemistry of digestion; if you pile a huge amount of food into your gullet, you’ll fell full quite quickly (or at least you ought to - after all, you are full. If you steadily and fairly slowly eat a smaller pile of nutrient-rich food, your body will begin digesting it and your blood chemistry will change in such a way that your brain can recognise that you are now in possession of the desired level of nutrition - obviously that’s going to take a bit longer to happen.
