No. God exists necessarily, it is his essence to exist. Therefore, He can not not to exist.
We see this from scripture also, Exodus 3:14:
God said to Moses, “I AM WHO I AM. This is what you are to say to the Israelites: ‘I AM has sent me to you.
From this follows that God does not need anything that is extrinsic to Him to sustain Him.
Also note that God is not material, but pure spirit. This is confirmed by the scripture in John 4:24:
God is Spirit, and His worshipers must worship Him in spirit and in truth.
Edit. About Jesus specifically and does his human nature require him to eat and drink the answer is no. You can find an explanation in Aquinas's Summa Theologiae here.
In short God is the progenitor of all things, nothing exists outside of Him therefore He is all sufficient and in need of nothing. Especially not food or water.
The question ought to be qualified because Jesus the second person in the echâd Godhead has existed as God in four different forms.
And whilst incarnate because of the limitations of the body given Him, He got hungry.
“And after fasting forty days and forty nights, he was hungry.” Matthew 4:2
But generally people think of God the Father or the Holy Spirit in spirit form. Bible says
“God is spirit, and those who worship him must worship in spirit and truth."” John 4:24
Jesus makes a distinction between a spirit and a body (whether mortal or glorified)
“See my hands and my feet, that it is I myself. Touch me, and see. For a spirit does not have flesh and bones as you see that I have."” Luke 24:39
The Bible also says this about the Kingdom
“For the kingdom of God is not a matter of eating and drinking but of righteousness and peace and joy in the Holy Spirit.” Romans 14:17
Sustenance is not therefore necessary though heaven does contain food and water
“Yet he commanded the skies above and opened the doors of heaven, and he rained down on them manna to eat and gave them the grain of heaven. Man ate of the bread of the angels; he sent them food in abundance.” Psalms 78:23-25
“Then the angel showed me the river of the water of life, bright as crystal, flowing from the throne of God and of the Lamb” Revelation 22:1
Not forgetting the marriage supper of the Lamb which is a feast and banquet
But does God need food and water? No, quite simply if He did then He would not be all sufficient and yet Scripture says that He is and that all things derive their existence from Him, by Him and for Him.
“For from him and through him and to him are all things. To him be glory forever. Amen.” Romans 11:36
God being life doesn’t need anything to gain or maintain life. Food and drink need God to exist but God doesn’t need food and drink.
It's an odd question.
Surely you know that God needs nothing.
He lived for an eternity before he made the Universe. For an eternity, before God made the Universe, with its food and water, there was literally nothing except God.
He didn't need anything then, and he doesn't need anything now outside of himself.
Perhaps you are wondering if Christianity is even slightly in agreement with common knowledge and common sense?
The Bible makes clear God made all things out of nothing:
"In the beginning God created the heavens and the earth." Genesis 1:1
So said the Apostle Paul in the New Testament of the Bible:-
"Then Paul stood in the middle of Mars' hill, and said, Men of Athens, I perceive that you are very religious in every way. For while I was passing through and examining the objects of your worship, I also found an alter with this inscription, "TO THE UNKNOWN GOD". Whom therefore you worship in ignorance, him declare I unto you.
God that made the world and all things in it, seeing that he is Lord of heaven and earth, dwells not in temples made with hands; nor is he served by human hands, as though he needed anything, since he himself gives to all life and breath and all things; (Acts 17:25)
and he made from one man every nation of mankind to live on all the face of the earth, having determined their appointed times and the boundaries of their habitation, that they would seek after God, if perhaps they might grope for him and find him, though he is not far from each one of us;
for in him we live and move and are; as even some of your own poets have said "For we also are his children".
Being then the children of God, we ought not to think that the Divine Nature is like gold or silver or stone, an image formed by the art and thought of man.
The times of this ignorance God has overlooked: but now he commands all men every where to repent because he has appointed a day, in the which he will judge the world in righteousness by the man he has ordained, and he has given assurance to all men, in that he has raised him from the dead. (Acts 17:22-31)
