Question on Branched Chain Amino Acids and Atkins

I have a question - and I have no idea about the effect of amino acids on
weight loss during atkins, hence my reason for asking my intellectual
betters.

Would taking BCAA's (Branched Chain Amino Acids) supplements (apparently a
combination of Leucine, Isoleucine and Valine) be a good idea on Atkins.

Apparently it helps prevent muscle loss and is touted as helping with fat
loss over muscle loss (could be a load of crap though).

I realise I probably already get some of the benefits of this type of amino
acid from eggs etc. but was wondering if supplementing on it would have any
adverse effects and perhaps interfere with ketosis perhaps, or actually
promote it.

Anyone who can offer any insight I'd appreciate it.

Cheers

John
