I second Rachel Myr's excellent theories

From what I have read, total fat content in breastmilk is relatively stable across all women irregardless of their diet.

"Although maternal dietary fat intake does not affect the total amount of fat in a mother's milk, the types of fat in the diet do influence the composition of fatty acids in milk."  from Breastfeeding and Human Lactation, 3d Edition, Jan Riordan, p. 105.

I have an interesting article from the Food and nutrition bulletin, Vol 17, Number 4, December 1996 by Ann Prentice that describes when malnourished women were given supplements "Breastmilk fat and protein concentrations were increased slightly by the supplement, but lactose levels fell, resulting in only a marginal effect on total breastmilk energy."
