Banting's Diet was devised for him by Dr. Harvey. It consisted of animal food, 13-16 oz.; bread, 2 oz.; fruit and vegetables, 6-12 oz.; total fluid, 35 oz.
9 a.m.....A large cup, 9 oz., of tea without milk or sugar.
One oz. of toast or a little biscuit; 4-6 oz. of beef, mutton, kidneys or broiled fish.
2 p.m.....Two or three glasses, 10 oz., of claret, sherry or madeira. One oz. of dry toast; 5-6 oz. of lean meat, poultry, game or fish; any vegetable except potato, parsnip, carrot, turnip or beetroot; unsweetened cooked fruit out of a pudding.
6 p.m.....A large cup of plain tea, 9 oz.; 2 or 3 oz. of cooked fruit, and toast or a rusk or two.
9 p.m.....A glass or two, 7 oz., of claret or sherry and water;
3 or 4 oz. of meat or fish as at dinner.
A glass of grog, without sugar, or a glass or two of claret or sherry was allowed as a nightcap.
Pork or veal; eels, salmon and herrings; champagne, port and beer; certain vegetables above mentioned.
There is no apparent reason for not allowing veal, its calorie value being little higher than beef and much lower than mutton. According to some analyses the percentages of fat in meats are: veal 16, mutton 5, beef 3. If this is always so veal is the least suitable. The amount varies in all meats with the fatness of the animal or bird. Water is not limited and should be taken in considerable quantities to aid in the elimination of the products of protein metabolism. The excessive amount of protein food throws an unnecessary and serious strain on the kidneys. A prolonged diet of this nature is liable to set up dyspepsia and intestinal disturbance, debility, nervousness, depression and insomnia. Metabolically it is unsound, for an excessively high amount of protein has to be taken and broken up to supply heat and energy, in place of the fat and carbo-hydrate foods which are so strictly limited. Even then only about 1,100 calories of heat are produced, and protein tissue metabolism will prove insufficient and fail. Another objection is the alcohol. It is unnecessary. Unless the wines recommended are of good quality they are liable to impair the digestion and cause rapid loss of weight. Probably, unless there are special indications for its use, it would be better to omit them entirely and allow instead some fat and more carbohydrates. Sufficient fat and carbo-hydrate should be given to maintain nitrogenous equilibrium. Then, any increase in the metabolism of non-nitrogenous substances, the result of exercise or cold, etc., would reduce the amount of fat in the body.
