There are many synonyms for "respect": esteem, admire, honor, revere, venerate, hold in high regard, think highly of, defer to, endorse, and many others. So you have a number of options.
Specifically using "respect", these would be examples of the more common expressions:
I respect him.
I have a lot of respect for him.
He is well/widely respected
He commands respect (wherever he goes).
Saying someone "deserves respect" often implies that the person isn't currently getting a lot of respect. For example, someone might say:
As the president-elect, Donald Trump deserves your respect.
Which implies that you currently don't respect him as that person thinks you should. So it's actually kind of the opposite of saying someone is "widely respected".
"Respect-worthy" is not natural English. You might think the adjective "respectable" would fit, but actually it doesn't really mean "someone who is respected" but rather just "someone of good social standing" or simply "of a reasonably high level", "well above average", or "decent".
He is a respectable person (he has a decent reputation).
He has a respectable income (a fairly good but not awe-inspiring income).
Of course there are many other ways to say someone is respected (or worthy of respect). This is not a comprehensive list, but I would start with the four patterns I provided.
You could say:
I'm not hungry.
I'm full.
We say that someone is "off (their) food", "have lost (their) appetite" or "don't have an appetite" when they are sick and the disease makes them not want to eat.
She had a fever on Wednesday and was off her food all Thursday. But on Friday morning she had got her appetite back and ate a big cooked breakfast.
— Mum, I'm full. I don't want to eat the cabbage.
— If you don't finish your cabbage, you won't get ice cream
— But I'm hungry for ice cream; I'm just not hungry for cabbage.

The rule you have learned (how+adj+a/an+noun) with the restriction on "the" only applies to direct questions. With reported speech, indirect questions, and direct statements you can use "a/an" or "the."
The following examples all work:
In statements and reported speech, using "the" is perfectly fine with both countable and uncountable nouns. The following examples are both fine:
