A young man in Las Vegas has lost more than 100 pounds since the beginning of the year, intent on gaining entry into the Army. Luis Enrique Pinto Jr., 18, lost 113 pounds over a seven-month period in order to meet the branch's weight requirement, dropping from 317 pounds to 204. "That's a human -- he lost the equivalent of a human in seven months," said his recruiter, Staff Sgt. Philip Long.
