I watched the show, and while I did enjoy it, it seemed to me that the points he made were pretty common sense stuff.
If I remember right, he said he had 4 "golden rules" to follow.
#1. Eat what you want.
#2. Eat when you are hungry.
#3. Eat consciously.
#4. When you are no longer hungry, stop eating.
Rules 1 & 2 are pretty self explanatory. #3 was explained this way:
Be conscious of what you are eating. Have no distractions. No tv, no books, no music, no computer. Savor each bite, take a forkfull, put your knife and fork down, chew for 20 times, take out the next forkful, do the same until you are no longer hungry.
He also did an experiment that I found interesting. They took 6 people and put them in a diner. They each had the same meal, a full breakfast of eggs, bacon, sausage, potatos, and toast. They all ate the whole meal. The next day, they went back for the same meal, but this time, they were blindfolded, and did not know the amount of food on their plate.
End result, becaues they could not see all the food, they didn't eat all the food.
