New Guinean Highlanders

The New Guinean Highlanders subsist on low-caloric diets consisting mostly of sweet potatoes. These supply about 90 percent of the Highlanders total caloric intake. Adult Highlanders do not consume more than 25 grams of protein a day. Therefore, their lean body mass decreases noticeably with age. The muscles in the arms and the calves become measurably smaller after age 30. The one advantage of a low-calorie diet is the low intake of fats. A diet lacking fats keeps blood pressure low and serum cholesterol levels low. People who are concerned about excess weight in their upper arms, thighs, and buttocks may wish to consult their physicians about the possible value of a similar diet.
