How many Calories do you need ( article by Ken)

[HunterNurturer]

This doesn't take into account the fact that when you reduce your caloric intake, your metabolism slows down as a result, which means you burn less calories.
It depends how active you are/will be, but while hunkering down/bugging in I know I could comfortably live on 1200 calories per day. Half of Asia survives on a similar amount.
