Cubby, about working out on empty stomach are you doing this as some kind of experiment or just because you find you perform better this way ?
Anyway I think its good. In the morning I usually dont feel like eating until I do some physical effort.
This thread is interesting but why stop there ? If short fastings have some benefits, is longer fasting can also be beneficial ? In my opinion longer fasting is just the continuation of IF and the benefits can be similar.

''Gain and Loss of Strength While Fasting''
"In the test made by Luciani on Succi in which a dynamometer was used, the strength of the right and left hands showed results seemingly at variance with the popular impression. Thus on the twenty-first day of the fast, Succi was able to register on the dynamometer a stronger grip than when he first began. From the twentieth to the thirtieth day of the fast, however, his strength decreased, being less at the end than in the beginning of the fast. In discussing these results, Luciani points out the fact that Succi believed that he gained strength as the fast progressed. Considering the question of the influence of inanition on the onset of fatigue, Luciani states that the fatigue curve obtained by Succi on the twenty-ninth day was similar to those obtained with an individual under normal conditions."
"On the last days of his fasts Succi would ride horseback or ascend the Eiffle Tower of Paris, running up the tremendous staircase that tires the average man to merely ascend it."
Levanzin lost no strength during his thirty-one days' fast as shown by the dynamometric tests. On the last day of the fast, this non-athletic man, used to taking no regular exercise except walking, was able to press up to one hundred and twenty pounds with his left hand.
It is somewhat amusing to read that at the end of his fast of thirty-one days in the Carnegie Institute, Levanzin wanted to continue it up to forty days and that Prof. Benedict objected because it would be very expensive and fatiguing to his well-fed men.
Dr. Tanner's strength decreased until after he began to take water, but increased thereafter. He was challenged by a reporter who declared one could not keep up his strength without eating. The Doctor said: "Here have I been for several years a semi-invalid, suffering from all kinds of diseases, and now I have fasted for two weeks. You are young, healthy, strong and vigorous. I will just take a drink of water and then I will run you a race around this hall and see who can endure the longest."
The reporter confidently accepted the challenge and the race began. To the amusement of the audience, who had expected to see the young man easily win, the doctor easily and speedily outran his competitor, who puffed and blowed in his distress.
Mr. Macfadden says: "In several cases treated by myself, and also in a number of cases quoted by Dewey and Carrington, the strength increased from day to day, until the patient was enabled to walk several miles a day toward the close of a long fast, whereas at first he was unable to walk at all!"
Again he says: "It is a fact that has been demonstrated again and again that many individuals instead of losing strength by fasting, gain it. In one case a woman was carried to one of our institutions on a stretcher, so weak from malnutrition that she was unable to walk. Her physician had prescribed all kinds of nourishing diets which she had been unable to digest and in spite of food (or because of it--author's note), drugs and nursing she had rapidly grown weaker. She was at once placed on a fast, and to her amazement, she, day by day, increased in strength."
In my own practice there is the case of a man who was confined to bed and unable to get out of it, although eating three meals a day. At the end of a week of fasting he was able to get up and walk about the room, although still fasting. There is the case of another man who was so weak he could not walk from one room to another of his home without support. After two weeks of fasting he was able to go downstairs unsupported, go outside and have a sun bath and return upstairs to his bed. After fifty-five days of fasting he was still able to do this. He was much stronger at the end of his fifty-five days without food than when he began the fast.
In his "Why Did Jesus Fast," Rev. H. Arndt tells of an Italian fencing master who prepared for contests with a week of fasting and continuous practice and who had never been vanquished.
Freddy Welsh, one time light-weight champion of the world, always started his training for important fights with a fast of a week. He found that this shortened considerably the time required to get in condition for the fight. He never had to postpone any fights because of colds, boils, etc., as was often done by Joe Beckett, George Carpentier, and others.
In December 1903, eight athletes under the supervision of Mr. Macfadden entered a seven days' fast and performed feats of great strength and endurance under the watchful eyes of prominent medical men from different parts of New York. These eight men were entered on the list on Saturday night at the beginning of their fast and the same eight athletes presented themselves in the final contest of endurance on the evening of the seventh day of the fast.
Joseph H. Waltering, of New York City, won first prize in the races, winning the 50-yard dash in six and two-fifths seconds, the 220-yard run in twenty-seven and four-fifths seconds, and the mile run in six minutes, fourteen and two-fifths seconds. Gilman Low, of New York City, artist, health-director, athlete, won first prize in strength contests; lifting 900 pounds in a straight hand grip lift and throwing the 56-pound weight thirteen feet six inches. On the sixth day of his fast, Mr. Low lifted with hands alone 500 pounds twenty times in fifteen seconds, and 900 pounds twice in twenty seconds. In the back lift he lifted one ton twelve times in twenty seconds.
Following the Saturday night tests in the presence of doctors, to whom he desired to demonstrate that there was no deterioration of strength after a week of fasting, he lifted one ton twenty-two times in nineteen seconds.
Mr. Low did not break his fast until the end of the eighth day. Then, at Madison Square Garden, before the astonished gaze of 16,000 people, he established nine world records for strength and endurance, which stood for years before they were broken. These records are:
"Raising 950 pounds three times in four seconds.
Raising 500 pounds twenty times in fifteen seconds.
Throwing 56-pound weight thirteen feet six inches (for height).
Leg-lifting--Raising with legs alone 1,000 pounds fifty times in twenty-five seconds.
Leg-lifting--Raising with legs alone 1,500 pounds thirty-five times in twenty-five seconds.
Raising with legs alone 1,800 pounds eighteen times in eighteen seconds.
Back lifting--bringing all the muscles of the back into action raising 2,500 pounds five times in ten seconds.
Raising 2,200 pounds twelve times in twelve seconds.
Raising 2,200 pounds twenty-nine times in twenty seconds."
These remarkable records were made after eight days of fasting in competition with other men who had been eating regularly, Mr. Low going out of his class to do it. He has set other world records, after fasting at other times. On one occasion in reply to the claim of physicians that should one go without food for a week, one would be so weak one could scarcely walk and a few more days would endanger life, Mr. Low challenged any two of them to handle him in any way suitable to them after he had fasted for fifteen days. He asserted that after a fifteen days' fast he underwent a few years previously in Boston, he could have whipped his weight in wildcats.
Prof. Levanzin says: "Those who feel any lack of strength during a fast are to be classed in the same category with those who feel hungry. They are nervous and very impressionable people, and their sufferings are only the baneful effects of their too vivid imagination.
"If you suggest to yourself that you are strong and that you can walk two miles on the thirtieth day of your fast, believe me, you can do it without great difficulty, but if you fix in your weak mind that you are going to faint, and worry, and persist to worry about it, be sure that not a very long time will elapse before you faint really, a victim of your wrong auto-suggestion."
Much to his surprise, Sinclair had none of the weakness during his second fast that he experienced during his first fast. Mrs. Sinclair experienced much weakness during her first fast, but no weakness during her second fast.
