How taste & smell affects what we eat

I listened to a very interesting podcast today. The podcast is NeuroScene and they interview Dr. Alan Hirsch, a neurologist who specializes in smell and taste. The podcast revolved around how those senses affect how we eat. I recommend listening to the podcast but here is some notable points based on scientific studies:

- people who are less interested in their surroundings eat less, and the converse is true. So the best way to eat less is to eat by yourself with no TV. People who ate while watching an interesting TV show ate more food.

-The 'eat before 6pm' statement is true due to increased tiredness suppressing your cognital rational ability and letting your "id" come out.

-Diet soda is actually recommended to people who want to gain weight. This is because the fake sugar is perceived by your brain as real sugar. The brain sends a message to your pancreas to release insulin. The insulin causes the cells in your body to increase uptake of glucose. Since the sugar isn't actually there, this causes a drop in blood sugar which causes you to eat more.

-people ate more food if served on a larger plate/bowl.

Anyways, it challenged some ideas that I had about food, particularly about diet soda.

Paul McKenna did a special in the UK and on it he told about a study they did where they took a group to breakfast and let them eat whatever they wanted. The people really enjoyed their breakfast. The next day they took the same group to breakfast and everyone ordered the same meal that they had had the day before. The only difference was that everyone was blindfolded. Everyone ate less and also many did not enjoy what they ate. Very interesting.
