(CLV) Ro 14:1
Now the infirm in the faith be taking to yourselves, but not for discrimination of reasonings.
(CLV) Ro 14:2
One, indeed, is believing to eat all things, yet the infirm one is eating greens.
(CLV) Ro 14:3
Let not him who is eating be scorning him who is not eating. (fasting) Yet let not him who is not eating (fasting) be judging him who is eating, for God took him to Himself.
Not eating is called fasting.
(CLV) Ro 14:4
Who are you who are judging Another's domestic? To his own Master he is standing or falling. Now he will be made to stand, for the Lord is able to make him stand.
(CLV) Ro 14:5
One indeed, is deciding for one day rather than another day, yet one is deciding for every day. Let each one be fully assured in his own mind.
(CLV) Ro 14:6
He who is disposed to the day, is disposed to it to the Lord; and he who is eating, is eating to the Lord, for he is thanking God. And he who is not eating, (fasting) to the Lord is not eating, (fasting) and is thanking God.
This passage tells the readers not to squabble over which days to fast. YHWH gave no commands on which days to fast.
We can find an example of these set fast days in Luke 5: 33-35
How does any of this answer any of the questions presented in the OP?
The OP title specifically refers to Leviticus Chapter 11

Leviticus 11 was the title of your OP ....
Romans 14:1-23
As for the one who is weak in faith, welcome him, but not to quarrel over opinions. One person believes
he may eat anything, while the weak person eats only vegetables.
Let not the one who eats despise the one who abstains, and let not the one who abstains pass judgment on the one who eats, for God has welcomed him. Who are you to pass judgment on the servant of another? It is before his own master that he stands or falls. And he will be upheld, for the Lord is able to make him stand. One person esteems one day as better than another, while another esteems all days alike.
Each one should be fully convinced in his own mind. ...
Agreed fasting was included .... but verse 1 "believes he may eat anything" seems pretty clear ... seems both eating and fasting are both included.
Holds true in the lexicon as well ... I eat ... not I obstain (fast) from eating
phago: I eat
Original Word: φάγω
Part of Speech: Verb
Transliteration: phago
Phonetic Spelling: ([bless and do not curse][bless and do not curse][bless and do not curse]'-o)
Definition: eat
Usage: I eat, partake of food; met: I devour, consume (e.g. as rust does); used only in fut. and 2nd aor. tenses
so you say to compare with 1 Timothy.
A lot of different teachings covering many topics - in 1 Timothy (all chapters) ... but not all of them are related to food. ie Leviticus 11 (in OP title) (is all about food) ie eating of clean verses non-clean animals.
God did give permission to eat meat ... because of all the murmuring they did about not having it (tired of just manna) ... and they didn't have very good consequences out of it ... overall a vegetarian diet is best for us (more healthy)... no doubt.
so is eating meat a sin issue or a health issue?
Is our salvation dependent on what we eat?
We are all unclean are we not?
Sure I'm probably missing your point ... you'll need to clarify.
1 Timothy 4:1 gives Warning against Apostasy
and there is this ...
3They will prohibit marriage and require abstinence from
certain foods that God has created to be received with thanksgiving by those who believe and know the truth.
4For every creation of God is good, and nothing that is received with thanksgiving should be rejected,
5because it is sanctified by the word of God and prayer.
Are you equating Leviticus with that .... certain foods ....???
Guess you'll have to provide more explanation as to where you are coming from ... or going to.
