Well, at least for a year, probably longer. There was a study done in the 1930's where two men went on a hospital supervised all meat diet that lasted for one year. They experienced no negative side effects and came out of the study in better shape than when they started.

One of the participants in the study was Vilhjalmur Stefansson, the artic explorer. With his experience and observations of arctic native cultures, he realized that many primitive cultures subsisted on almost exclusive meat diets for many months of the year. He in fact lived for nearly 5 years with the Eskimos (Inuit) eating their native diet of meat and fish and little else.

The year long experiment took place at Bellevue Hospital, New York. The study was designed to find the answers to these questions:

Does the withholding of vegetable foods cause scurvy?
Will an all-meat diet cause other deficiency diseases?
Will it cause mineral deficiencies, of calcium in particular?
Will it have a harmful effect on the heart, blood vessels or kidneys?
Will it promote the growth of harmful bacteria in the gut?

The results of the year-long trial were published in 1930 in the Journal of Biological Chemistry and showed that the answer to all of the questions was: NO. There were no deficiency problems; the two men remained perfectly healthy. The diet consisted of ~2000 - 3000 calories per day of meats (much of it raw) including fat (much fat in fact). Fat made up about 80% of their calorie intake.
