I want to know the answer to the following question:
Do girls who are malnourished start menustrating earlier or later than those with high-fat diets?
All the background I'm provided with is that "Consequently, girls who have a high-fat diet and who are not physically active begin menstruating earlier, on average, than girls whose diet contains less fat and whose activities involve fat reducing exercise (e.g. ballet and gymnastics).". Is that enough to answer the question?
Answer: no
