In 1914, the trouble with most thin folks who wished to gain weight was that they insisted on drugging their stomach or rubbing on useless "flesh creams" or following some foolish physical culture stunt while the real cause of thinness went untouched. One could not get fat until the digestive tract assimilated the food eaten. Thanks to a remarkable new scientific discovery, it was now possible to combine into simple form the very elements needed to help people convert food into rich, fat-laden blood. This master-stroke of modern chemistry was called Sargol and had been termed the greatest of flesh builders. Sargol aimed to soak up the fattening elements of food and pass them into the blood where they could be carried to every starved, broken-down cell and tissue of one's body.
