Who is willing to go without sugar, even with financial incentives? Even on behalf of sugar research, who would the control groups be?
- People who are going to lie--"Sure I'll go without sugar for 6 months for your study!"
- People who go into it honestly, but fail--"Um, Mr. Researcher, I, uh, had an accident the other day, and then the day after that, and, uh, I failed."
