I put mine facing the beautiful, mountain vista outside my wall of windows, out of the corner of my eye I can see my Mercedes benz SUV, that I use to take to my private jet used to get to climate changes conferences and Hollywood awards shows.Fife wrote: Mon Jan 28, 2019 12:39 pm You all are a really hip crowd.

You've probably heard alcohol crushes muscle building. And in this area you are probably correct. My friend back in college may have stayed lean, but his alcohol habit may have been the reason he couldn't put on size. Alcohol has several mechanisms that will negatively impact muscle protein synthesis and recovery from exercise. However, as long as you keep it moderate you may be safe.
Alcohol has these effects on muscle metabolism: raises myostatin, decreases glycogen resynthesis, decreases post-exercise inflammation (yes, this is a bad thing), suppresses exercise induced mTOR (likely by reducing cellular phosphatidic acid) and it may impair insulin and IGF-1 signaling. If you're not a biochemistry buff, all this equals BAD for muscle.
However, there does seem to be some caveats. An excellent review by Matthew J. Barnes published in the June 2014 issue of Sports Medicine shows some very clear rules when it comes to alcohol and highlights several studies you'll want to know about. In one study, Barnes gave subjects 1g/kg alcohol or a equal volume of a non-alcoholic beverage. These drinks were consumed 30 minutes after having them complete 300 eccentric reps for the quads (ouch!). So, basically there was a group drinking the hell out of some booze and another group getting their swerve on with a jug of Tropicana (the control group drank orange juice).
Both groups were trashed 36 and 60 hours after the workout in terms of strength in isometric (holding), concentric (raising), eccentric (lowering) contractions. But the alcohol group's muscles had a much worse hangover. They performed 22%, 12% and 15% percent worse in those three measures compared to the OJ group.
To make this more tangible for you, and so you can understand how much booze was consumed, 1g/kg is 1g/2.2pounds. That equates to about 80g of alcohol for a 180-pound person. And since the average alcoholic drink (4-5oz wine, 12oz beer, 1.5oz spirits) has about 14g of alcohol in it, if my math is right, that's about six alcoholic drinks.
So the study results are about what you'd expect, right? But here's the part that you'll love if you like to drink. Barnes did a similar study where he pitted 1g/kg alcohol consumption against .5g/kg alcohol consumption. And that showed once again that the 1g/kg alcohol level torpedoed muscle recovery, but the .5g/kg alcohol consumption had no effect.
So for that same 180-pound dude, six drinks crushed him. But three drinks and he stayed in the clear. That's a pretty useful rule of thumb if you ask me. And this same threshold level of .5g/kg alcohol is backed up on other studies showing higher levels negatively impact rehydration metabolism.
Like I said, if you reduce it to about three alcoholic drinks on a single off-day, it probably won't hurt you.California wrote: Mon Jul 22, 2019 6:45 am If I ever drink alcohol, it messes up my whole program. Hunger, laziness, and everything else that's anathema to exercise and diet.
Does TRT help the fight against fat that we have when we're in our thirties and above? I'd love to be able to be a little less restrictive in my diet; I'm already burning over 3k calories a day.
