Not that hard to live off of cheese and peanut butter crackers for six weeks, if you have access to water.
Six weeks is 42 days.
Need 1500 calories a day for comfort, and may scrounge some more calories from the environment.
About 11 ounces per day, at most. 11x42 = 462 ounces, or 29 lbs, at most.
Might get tired of peanut butter and crackers, but not so much if you are actually hungry.
More peanut butter and less cracker would bring the weight down a bit.
Hes not there it was just an elaborate trick ... he left the country ...
