My brother, your brain is benumbed. A man who disposes of the quantity of food that you do should be a laboring man. Exercise is important to digestion and to a healthy condition of body and mind. You need physical exercise. You move and act as if you were wooden, as though you had no elasticity. Healthy, active exercise is what you need. This will invigorate the mind. Neither study nor violent exercise should be engaged in immediately after a full meal; this would be a violation of the laws of the system. Immediately after eating there is a strong draft upon the nervous energy. The brain force is called into active exercise to assist the stomach; therefore, when the mind or body is taxed heavily after eating, the process of digestion is hindered. The vitality of the system, which is needed to carry on the work in one direction, is called away and set to work in another. (2T 413.1) MC VC

You need to exercise temperance in all things. Cultivate the higher powers of the mind, and there will be less strength of growth of the animal. It is impossible for you to increase in spiritual strength while your appetite and passions are not under perfect control. Says the inspired apostle: “I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.” 1 Corinthians 9:27. (2T 413.2) MC VC
