The “stardust bar” approach

Would it be beneficial to me, to remove ALL joy from my food for the first couple weeks of January? As in do kinda like your stardust bar example, but I would literally just eat the blandest food I can come up with? (I’m thinking plain ass chicken breast with broccoli)
Just to train myself into dealing with what all remains?

What do you think. Could this be a disaster or no.

The only thing that I think would go wrong is if I somehow blew up after the 2 weeks and overate like crazy due to feelings of justification.
But- I can only see myself wanting to do that if I DID NOT face my emotions properly during the 2 weeks though.
Like if I’m TRULY TRULY sitting with my emotions and learning what is going on with me, the blow up probably won’t happen….?

I hope I explained this to where it makes sense. I just can’t decide if this would help me or hurt me lol.

The truth is, I really just want to get this right and blow through the hard part first. Lol. That’s my intention for wanting to do this. Not sure if that’s the best approach, but I’m just so eager I guess.

Please let me know your thoughts.
I’m 27 years old and weigh 264.4 pounds, just FYI.
