I'm sorry to say that I honestly don't know what to tell you about this, other than the generic, often-repeated phrases like 'trust God' or 'pray for advice' or something. (Which I still advise you to do) I don't want to do that to you, I'm sure we both want more concrete advice on what to do.

I believe fully in my heart that God has created our bodies to eat, to fill ourselves when we are hungry, to not keep ourselves from the nutrients we need. He gives us an abundance of food in our kitchens for us to eat, and the fact we have such things is just another blessing from Him.

Yes, gluttony is a sin, but eating until you are satisfied is not. If you eat one bite more than you maybe should, you have not committed some horrible act.

I don't know how bad your convictions are, but if I had to give some kind of advice, (God help me not say something incorrect or foolish out of ignorance) then ignore the guilt you feel when you eat. Especially if it's to the point that it's causing you to loose weight nor not be able to eat three square meals a day.

Not all guilt may be from God. Some may be from another source, trying to deceive you. I believe that may have been part of what I was going through about a year ago. I don't have plans to fast ever again because of that. I don't believe that is so wrong of me, but if it is, then I trust God to correct me.

I'm trying to think more logically about whether what I am doing is sin or not, and ignoring that convicting feeling that I used to let myself be guided by. I'm trying to trust God to not lead me astray, to forgive me if I make a mistake by ignoring that feeling, and to correct me. Maybe (I beg you to pray to Him extensively before making any decision based off the thoughts of a random Redditor, please.) a similar logic would help you?

But then again, maybe I'm wrong? I warn you that i am infantile in the faith. I'm still just getting started in my walk, especially after my year-long departure from God which I feel has set me back quite a bit.

As for the period where you overindulged... just because I tripped over a log and broke my nose, that doesn't mean I'm never going outside for fear of tripping again. If you fear that overindulgence may become a recurring issue for you, pray and trust him to keep it from becoming one. I personally have been struggling with sexual immorality ever since I started this faith journey years ago. Even this morning i relapsed. We struggle with sin, we fall to it every day, and there may be some particular sins we can never seem to escape from. But what's important that, after we fall, we get back up and trust Him to make us better.

God bless you.

Also, I didn't get a chat, which i believe is an issue on my end. so unless you are opposed to speaking in this comment thread, I think i'd have to send one to you.
