Gaining muscle tissue is "easier" but it takes much longer. The process of dieting is much more unpleasant, but it can be done in 2-3 months.
Muscle can only be built so fast, even on all the juice in the world. Takes years to build a quality physique
So true, if only I knew this in the beginning!
After a while though, eating thousands upon thousands of calories a day, constantly preparing food, eating, cleaning up, shopping, thinking about your next meal, being full all the time becomes very unpleasant. It is much harder to overcome a weight gain plateau compared with hitting a sticking point when losing weight. At some point your metabolism just catches up and you need to keep upping your calories.
