TTing is the best way because when you go up a level it stays. When you stockpile energy any other way (like eating the energy giving goodies)  when to go up a level your energy defaults to whatever the highest amount of that level is. For example:

If you eat something that gives you 600 energy points and you only need to win 100 more points to attain a new level that has a 200 point max then you will lose 500 points of energy because once you achieve that new level (assuming you only need to try one time and beat one room to do it) you will end up with 200 points of energy instead of 500 points of energy.
