Ehret traces his journey from serious illness to renewed health through experimentation with fasting and diet, showing how personal crisis can drive radical self‑experimentation.
His story frames the mucusless diet and fasting not just as techniques, but as discoveries earned through trial, error, and near‑fanatical persistence.
The autobiography functions as a recruiting tool: Ehret presents himself as living proof that modern degenerative disease can be reversed by obeying "nature’s laws."
