Q: How natural is it to build large muscle ? I ask as most people have to work very hard to eat lots of specific foods combined with heavy weights to get big plus your body is so fond of eating muscle to slow metabolism and storing fat, rather than burning fat. Below 10% body fat for most people their bodies stubbornly hold on to fat. Plus if people eat too much food weekly ? even if ?clean? they can easily put on excess fat. Should we really be fighting out bodies' natural instincts?

A: I'm not sure how natural or not natural it is -- human society changed so much in just a few thousand years that I think those terms are almost meaningless -- but having very large muscle mass and/or low body fat is most definitely not easy. However I don't think that should stop anybody from trying to achieve it if that's what they want to do. It's just like any other human endeavor: set your goals and try to achieve them. More often than not, even if you don't quite get to your goals the journey will still be very rewarding.

It is true that some people get carried away with their obsession for the 'perfect body' and start engaging in dangerous and self-destructive practices like using anabolic steroids, going on bogus and unhealthy diets, ignoring and exacerbating injuries, sacrificing personal lives and careers, and so on. This is certainly something to be mindful of. But if one can avoid these slippery slopes -- and most people certainly can and do avoid them -- then I see nothing wrong with setting high personal fitness goals and then working your hardest to achieve them.
