This has not been proven and in fact has not even been supported by credible anecdotal evidence, just another unproven hypothesis and an urban tarantula myth. The fact is that no one has ever done even an unofficial study. And, the effect probably differs widely and wildly with the species, sex and age of the tarantula.

I normally suggest power feeding baby tarantulas (e.g., 6 baby crickets a week) to grow them out of the fragile infant stage as quickly as possible. I recommend feeding tarantulas that are large/old enough that they're molting only once a year only one or two crickets a week (4 to 10 crickets a month). Prorate the feeding of intermediate sizes/ages according to an estimate of body mass.
The really huge, giant tarantulas (e.g.,
T. blondi and
L. parahybana) must be fed more, of course. Again, prorate their feeding based on estimated body mass.
Power feeding spiderlings and larger tarantulas sometimes has unpredictable results. Unless you have had prior experience and know what you're doing, I'd discourage the practice.
May I suggest that you go to the
Spiders, Calgary webtree
and start reading.
