Generally spoken, this is definitely wrong. Fat isn't like fat. It depends
strongly on the fat acids. If you have many unsaturated fat acids, this is very
good for the fecundity as with these more prostaglandines can be produced. Only
saturated fat acids may cause liver problems. It's different in the metabolism
to men, nevertheless both should prefer the unsaturated fat acids.
