There is no debate because you have once again failed to either understand what was posted, or didn't bother to read all of it.
Again, you emphasize your criticism of the advice given on his macros, BUT STILL HAVEN'T SAID WHAT YOU THINK THEY SHOULD BE. Now you're making a claim that the recommended macros will damage his liver and kidneys, when the scientific research goes against that.
I cited to Google as a joke, obviously it went over your head. It was my way to point out to you that there are SEVERAL credible RESEARCH STUDIES out there that show what you are saying as no basis, and are very easily found. Perhaps you didn't have the time to get to it before your break ran out, but you should really do your research before trying to say everyone else is wrong, not give anything to back up your conclusions, and declare yourself the interwebs debating god.
I know you haven't researched or talked to any high level athletes if you think 2700 is way too much. I've already shown from the information given how reasonable the numbers are. You have once again given nothing to back your claim that 2700 is way too much for someone to lean bulk, when they are currently 5'10, 160 lbs, 21% BF, male, and 23 years old.
You specifically said "I also have yet to see ONE credible source prove that if you want to gain muscle, do a gram of protein per pound of body weight. Usually when they suggest this, they are trying to SELL you a protein supplement as well...think about it." You did not qualify who "they" was, thus only limiting it to anyone that gives such advice. Above, Scott recommended he drop his protein from 270 grams, to 225, knowing the OP's bodyweight is currently 160 pounds. That is in fact over your threshhold of one USUALLY out to sell supplements. So by your logic, Scott is probably trying to just sell him something right?? Think about it... it's your logic. If you do in fact think Scott's advice is credible, well, you have your one credible source above, disproving yourself. Otherwise, I will again refer to Google if you still are unable to find such credible sources.
Yes, he might gain "some fat". No, his belly fat will not entirely dissapear through a lean bulk alone. But it will improve far greater than someone who is skinny fat trying to cut. Again, you fail to comprehend what it means to be skinny fat, because if you did you would understand the obvious solution. By going on a lean bulk, he is very likely to reduce his overall body fat percentage while gaining lean mass. This alone will improve his physique. Add on top of that body recomposition as a new trainee, he will most likely gain the mass while burning fat. And I CAN assume this because he said he is skinny fat. Again since you don't seem to understand, skinny fat is someone who has a low body mass index, but very little muscle. VERY LITTLE MUSCLE. Someone with very little muscle is in the far spectrum away from their genetic potential. When someone like that does weight training, they experience large improvements in a short amount of time. That's what "newb gains" are. Someone who dicks around in a gym for 3 years but doesn't actually make any improvements in muscle gains doesn't waste away their newb gains. It's about how far someone is from that genetic potential, NOT JUST IN HOW MUCH TIME YOU'VE SPENT IN THE GYM. If you understood that, you would see body recomposition is a good possibility.
Again, I don't know where you are calculating what his caloric intake should be to reach the conclusion that his macros are too high, so maybe share your significantly greater knowledge with us. I guess we need you to school Scott in nutrition, seeing how you said his advice was so obviously wrong.
And I'm missing where the OP said his goal was to put on 20 pounds in one year. Can you please point out where the deadline is coming from? First you took issue with it being "20 pounds as fast as possible" but now you've changed the OPs goal to under one year. Maybe he can set his own goals? Let me use your own logic here again - You're saying he should cut his bodyweight down AS FAST AS POSSIBLE. That would be incredibly unhealthy! Now of course you didn't actually say that, but neither did the OP say, or Scott tell him, to gain 20 pounds as fast as possible, or in his first year. But I'll just use your own logic to make the point, and declare myself the new "winner" of the argument. And 20 pounds of LEAN MASS is definitely attainable for first year lifters, so no, your statement that "[p]utting on 20 pounds even in one year will most likely mean a lot of it came from fat" is misleading, at best.
It looks like all the assumptions have come from you. Rather than ask clarifying questions, you've criticized the advice given by Scott, but failed to provide any valid reason as to why other than you disagree, and again have failed to give your insight as to what his macros should be. Since you disagree, WHAT DO YOU THINK HIS MACROS SHOULD BE? Since you are so well researched to make statements discrediting Scott's advice with "I also have yet to see ONE credible source prove that if you want to gain muscle, do a gram of protein per pound of body weight", when he in this thread gave advice of over that amount, don't forget to cite your sources. Otherwise I would just recommend to the OP that he follow Scott's advice over yours.
