Self-study
Medical research has established that the Beta Diet is healthier than a more conventional diet. ███ ██ ████████ ██████ ███ ████ ████████ ███ ████ ████ ███ ███████ ███████ ███ ████ ████ ██████ ██ ██ ██ ████ ██████ ████ ███ ██████ █████ ████ ██ ████ █████████████
"Surprising" Phenomenon
Why do people who follow the Beta Diet for decades suffer from below-average health?
Objective
Any hypothesis resolving this conflict must state new information about the Beta Diet or the people who follow the Beta Diet for decades. That information must result in those who follow it for decades being less healthy than average, either because the diet has a different effect over an extended period or because those people are unhealthy in the first place.

a
On average, people ███ ████ ████████ ███ ████ ████ ███ █████ ██████ █████ ███ ████ ████ ██████ ██ ████ █ ███████ ██ █████████ ██████ ████ ███ ██████ █████ ████ ██ ████ █████████████
This deepens the mystery. If consistent followers of the diet have other healthy habits, their below-average health after an extended period is even more surprising.
b

This explains why people who follow the Beta Diet for decades are likely to suffer below-average health. They are unhealthy because of a condition the diet is intended to treat.

People of average ██████ ███ ██████ ████ █ ████████████ ████ ██ ███ ████ ████ █████████ ████ ████ █████ ██████ ████████ █████████████ ██ █ ███████
This makes no claim about people who follow the Beta Diet for decades. A short-term health benefit does not explain health problems that occur decades later.

The Beta Diet ████████ ████████ ██████ ████████ ███ ████ ██████ ███ ████ █████ ████████ ███ ███████
This does not imply that the Beta Diet has negative effects on the health of some people. It claims only that dieters benefit to different degrees.

This does not imply that the Beta Diet is unhealthy, or responsible for the poor health of its long-term followers. It allows the possibility that the Beta Diet is healthier than the average diet over the long-term, in which case the conflict remains unresolved.
