Madame Sylvia created a diet for Mary Duncan she described as "A diet for adolescents inclined to plumpness" (Hollywood Undressed, Page 186).

Breakfast
1/2 Grapefruit
2 slices of crisp rye toast with thin butter
1 cup coffee, clear
1/2 Cantaloupe
1 broiled lamb chop
4 heaping Tablespoonfuls of Cauliflower
2 heaping Tablespoonfuls of Summer Squash
2 Leaves of Lettuce
3 slices of Tomato, diet dressing
1/2 slice whole wheat toast, no butter
1 cup coffee, clear
1 Tomato Juice Cocktail
Russian Salad, Diet Dressing
1 slice of Roast Beef or 2 slices of Roast Lamb with "lean" gravy
3 heaping Tablespoons of Spinach
2 heaping Tablespoons of Brussel Sprouts
1/2 slice of Whole Wheat Toast
1 small dish of Strawberries
1 glass of Skimmed Milk
Demitasse Coffee
I think Madame Sylvia's diet for Mary Duncan sounds pretty decent. Some of the quantities seem strange like only 2 leaves of lettuce with lunch, but there must be some reason for it.
