This is a bit different than the authors "general" orange juice fast.
--------
For the first day, no food at all ought to be eaten, but one or more glasses of water (hot, warm or cold), ought to be taken every hour up until 6 p.m. While more than one glass may be taken it is well for the obese person who is fasting to keep as nearly to one glass of water each hour as is comfortable, for some fat people seem to make fat even upon water. But the one glass an hour is needed to keep down hunger and keep the body processes normal.
For the second day the regimen may be the same, except that the juice of one orange may be added to the glass of water every hour.
On the third day a half glass of orange juice diluted with as much water may be taken every two hours. On the fourth day an entire glass of pure orange juice may be taken every two hours, water being drunk, if any, only for thirst.
For the next three days the diet is to consist of two apples or two oranges two or three times each day. A glass or two of half-and-half (milk and hot water), may also be taken at each meal, but the fluid must be well chewed into the fruit.
