                                            A recent reminder... hang onto your lean muscle mass, and keep moving no matter what your age!!                                        
                                    
                                                                        
                                        A very interesting new study* just came out. It involved patients with sarcopenia, which means they had low muscle mass, who were going in for liver surgery. A very serious procedure. 
One group of the patients underwent a prehab program. For 6 weeks prior to surgery, they walked 7 days a week and lifted weights twice a week. They also got nutritional consulting and took amino acid supplements. 
 
The other group, the control group, did nothing. They just waited for their surgery to happen and then got surgery. Then the authors compared the complication rate for each group.
 
Almost 50% of the control group had postoperative complications.
 
Just 10% of the prehab group had complications. They had much better results.
 
Prehab is a novel concept in the conventional medical world. Yet, of course, here in the Primal world and other adjacent communities, we have always talked about getting ahead of problems before they occur.
 
What’s funny is this so-called prehab program is very similar to what anyone should be doing on a regular basis just to be healthy: walking every day, lifting heavy things twice a week, eating plenty of protein and a nutrient-dense diet. That is the bare minimum. That is what our genes expect from us. 
 
And it turns out that that is so shockingly physiologically normal, so in line with what our bodies expect from us that, you can take unhealthy people who need serious liver surgery, have them do a basic program for six weeks, and almost eliminate their risk of serious complications from high-risk surgery. That is how fundamental it is. 
That is how quickly we can make a difference in our lives—or in the lives of those around us who might not have all the knowledge we do—just by making a few minor changes to our diet and exercise. 
 
Living this way makes you more robust in the face of anything that might affect you.
