UPDATE: I have edited this post because it contained factual inaccuracies. Earlier, I was showing Table 1, which was the protein-bound value of BCAAs. We’re looking for the free form calorie total, which is table 2, now shown. See edit history to see differences. Thanks to Alan Aragon for the correction.
Actually this is one thing I was pondering adding to the post, but it really didn’t belong in the context.
But check this out:
BCAAs are more like 4.6 calories per this table… but if you count it as “protein” (4cals) you should be close enough.
