Everything in moderation has its place and time.

That is a fairly reliable heuristic, although I would say that Americans ideal of "moderate" fat intake is wrong: we consume far too much fat, especially from PUFA sources.
30-50g of good saturated fat is enough, maybe a little more if you have tons of muscle.
0.7-0.8g of protein per pound of goal bodyweight, and then gentle natty carbs for energy otherwise.
