A man should treasure his doubts:
If consuming tasteless calories lowers your set point, then anyone who loses their sense of smell should lose weight like crazy.
I do not know, but I think that this is not true.
The Shangri La Diet book was a best-seller. Many people must have tried it, even though it sounds crazy and I can quite see why people would not go around admitting that they were trying it. But if it works for most people, then surely people who tried it and had it worked would tell other people. People are usually happy to go around spouting the worst craziness once they are convinced it's true.
So it should have spread by word of mouth and taken over the planet by now.
More arguments please. We can be like Greek philosophers, finding the truth without troubling ourselves to ask reality.
