This is basically what I was thinking when I read the study.
How do we differentiate between an actual increase in myofibrillar muscle hypertrophy versus sarcoplasmic hypertrophy versus a general increase in whole body water/edema?
The fatty liver is another thing. It is pretty clear (as far as I can tell) that the saturated group developed a fatty liver. The question is, is this a bad thing or a good thing in the context of this study? We know that saturated fat can be protective for the liver (against alcohol for example). I imagine there would be a fair bit of endotoxin finding its way into the liver on an overfeeding diet such as this, especially since the overfeeding involves roughly 750 calories worth of muffins.
It's also important to consider that other nutrients impact the ability to export fat from the liver. If the people on the SFA diet had adequate glycine, methionine, choline, vitamin A, etc then you might see different results. Plus, Palm oil is not exactly a low pufa oil.
