A raw food diet causes an average weight loss of 21.8 pounds in men and 26.4 pounds in women according to a study from Germany. Subjects
Subjects: 216 men, 297 women
The study looked at 216 men and 297 women who had been on a raw food diet for an average of 3.7 years.
15% of men and 25% of women were underweight
Body mass index (BMI) was below the normal range of, that is less than 18.5, often referred to as underweight, in roughly one out of every seven men (14.7 percent) and one out of every four women (25 percent).
Some Women Stopped Menstruating
30% of women had stopped menstruating
Approximately 30 percent of the women had stopped having their periods. The higher the amount of raw food that they ate, the more likely it was. Women who ate a diet containing more than 90 percent as raw foods were more likely to stop menstruating than women eating a more moderate raw food diet.
Conclusion: “A strict raw food diet cannot be recommended long-term”
“The consumption of a raw food diet is associated with a high loss of body weight,” the authors of the study concluded. “Since many raw food dieters exhibited underweight and amenorrhea [loss of menstruation], a very strict raw food diet cannot be recommended on a long-term basis.”
Comment: I am not convinced it is so bad
I am not convinced that the changes seen are all that harmful. I would like to see the results of a study looking at people who have been on a raw food diet for a long time, maybe 20 years or more, and see what they health of these people are. The only concern I can think of is that a loss of menstruation might also weaken the bones of women which could be a problem when they get older. But the advantage might be a reduction—perhaps a large reduction—in the risk of breast cancer.
