Do you remember Del Hall? The American from Ohio decided to undertake a rather unusual fast, one that involved 46 days of drinking and getting nutrients from nothing but … beer! Reviving an ancient monastic tradition, this somewhat idiosyncratic fast turned out pretty well for our subject: he is in good health, but even so, he’s lost more than three stone. He wants to continue following a beer-based (but no longer beer alone) diet to lose weight (before starting his fast he weighed around 20 stone). His “hoppy” diet has also enabled him to lower his cholesterol and his blood pressure.
