Starting in January of 1928 under the charge of Dr. Eugene Dubois, and his staff, Vilhjalmur Stefannson and a former explorer/cohort Karsen Anderson checked into the dietectic ward of New York City's Bellevue Hospital to begin the study. The men underwent a battery of tests and were kept under tight scrutiny. The whole ordeal was met with much fanfare complete with the press and all the doubting professionals who thought the experiment would not last long at all. As mentioned, the two men were to eat nothing but meat animal products such as beef, lamb, fish, chicken, liver, brains, and bacon fat. No fruits, veggies, eggs, or any other dairy products were allowed. All went well during the year. Both men exited the 1928 sutdy in excellent shape. Stefannson in faact had lost an extra 10lbs that he was carrying.. The significant issues here were that neither of them contracted scurvy or had any visible signs of bone deterioration from lack of calcium. Stefannson wrote extensively in 1935 of the dramatic effects of fresh meat in both preventing and curing scurvy. He strongly encouraged any men of exploration to either of the poles to rely on fresh, indigenous game for scurvy prevention, rather than relying on stored provisions including bottled lime or lemon juice.
Muscle, Smoke and Mirrors Volume One.
You can live off meat and fat. The same can't be said about soy, vegetables, fruits, or any thing else. If you tried living soley off the latter you'd die. There isn't any culture in the history of mankind that lived off fruits and vegetables alone. I.e. without atleast some sort of grain or insects etc.
