If a person is dying out of hunger then instead of giving him/her the raw materials to prepare food we would prefer to give ready-to-eat-food. Breakfast therapy is based on this principle. For example if a person is lacking hemoglobin and vitamin-B then he is given salad and germinated wheat, which are affluent in vitamin-B and promote formation of hemoglobin.
Also in morning time the digestive system of the body remains in restive and lazy mode, that is why we face difficulty in digesting heavy food in breakfast. On the other hand the germinated grains are easily digested and absorbed by the body and soon the vital deficiencies are removed.
