After reviewing the interview, I remembered reading it. However, I cann’t buy into everything he’s saying - all of it sounded like opinion and speculation - it wasn’t backed up by any studies or references or science. I remember reading about “chewing” your shake and even tried it for fun but seemed silly and annoying and I sure didn’t notice any benefit. And if it did make a difference, then we should be “chewing” all our drinks - how many of us has ever chewed their milk for instance? Not necessary, I believe. Although there are enzymes in salivia, most real digestive enzymes come from pancreas and liver. And in regards to not being able to properly digest a thicker shake, how the heck are we ever going to digest a steak or chicken breast as it doesn’t get any thicker than a chunk of steak. Your gut is designed to break every thing down and digest it. Eat a steak and puke later and even the steak will come up as being liquidfied by the gut. And that’s before it even gets in the intestines. I think he’s selling our digestive system short. True, some may have a degree of digestive problem, but most of us have a very effecient digestive system that can break down, liquify, and absorb just about anything. If any of this was true, than it wouldn’t make sense that current studies show the best protein utilization and LBM gains come from casein which “gels” or sets up and thickens in the gut so that digestion and absorbtion is slow and “time release”. Except post WO with Surge, it’s better for many reasons to have food digested and absorbed slowly rather than as quickly as possible.
