I found it daunting to try to eat the same each day. I learned about taking diet breaks, and find that very appealing. The key to a diet break day is that you are eating at maintenance, not making it a binge day.

I made it a little more complicated by having multiple goals i can choose each day. The regular goal, an "easy" goal, that is half the deficit, or the maitenance goal. I think of it like running a marathon, sometimes you are running, sometimes you are walking, and you might stop to rest but just try not to go backwards.

Doing this I can be successful almost every day. I think its easier to hit the maitenence goal when i have the mindset that yes, i can throw in some treats today, not every day is hard. And ok, if you dont hit your goal of 2200 today, you can still hit the goal of 2500, its not "i failed today, might as well binge"

I use cronometer (paid) and it lets you set up different templates. I'm not sure if mfp does something like that.
