Nineteen-Eighty-Seven marks the 75th anniversary of the expedition to the South Pole led by Captain R.F. Scott, during which he and his party died. Between November 1985 and January 1986, three men manhauled sledges 875 miles, following Scott's original route to the South Pole. They consumed an energy dense diet which provided 20.5 MJ/man/day of which 57 per cent came from fat. Despite the diet being well tolerated and allowing for dehydration, the men lost between 6.7 and 10.5 kg, indicating a daily energy expenditure of 25 MJ/man/day. Estimates from daily diary records of periods spent in different classes of activity and the literature values for energy consumption assigned to those classes, suggest a daily energy expenditure of 29 MJ/man/day. These estimates of energy expenditure were higher than expected and suggest that on Scott's last expedition, emaciation, secondary to a diet grossly inadequate in energy content, might have been a more important factor in his demise than has previously been thought.
1987年是由R.F. 斯科特上尉率领的南极探险队出发75周年，在那次探险中他和他的队员不幸遇难。1985年11月至1986年1月期间，有三个人拖着雪橇行进了875英里，沿着斯科特当年前往南极的路线前行。他们食用了高能量饮食，每人每天摄入20.5兆焦耳能量，其中57%来自脂肪。尽管这种饮食耐受性良好且考虑到了脱水因素，但这些人还是减重了6.7至10.5千克，这表明每人每天的能量消耗为25兆焦耳。根据每日日记中记录的在不同活动类别中所花费的时间以及为这些活动类别分配的文献中的能量消耗值估算，每人每天的能量消耗为29兆焦耳。这些能量消耗估算值高于预期，这表明在斯科特的最后一次探险中，能量严重不足的饮食导致的消瘦，可能是他死亡的一个比之前认为的更为重要的因素。
