I've only ever seen anyone on CF (christians and non-christians alike) use the word "prayer" to mean..."a request made to god".
Then you haven't read my post >

In prayer I request that God corrects me to get real with Him in how He has me loving, that He changes me to become more like Jesus, that He changes my character so I discover how it is to be really honest with Him. I would not stop making this request; because I obviously still need this, much more!!!!

lolololololololol
But about making requests for things like food and clothes . . . I don't ask for these things, but I trust God to provide for me, however He pleases, and that I will be obedient and good about whatever He wants me to have > "be content with such things as you have" (in Hebrews 13:5).
And I pray with my lady friend about if and how long we will keep her truck which we use for doing things we very appreciate being able to do. So, our prayer for our truck is really a request that we can keep doing the loving things we value doing.
So, it would not be natural for us to stop making requests for material things, because our loving people is connected with having things for loving others and having the health and means of transportation to reach certain people, and to share with each other at different locations.
And, "of course", with our requesting we also are thanking for all He has already done and is doing and will do.
And Philippians 4:6-7 includes "make your requests known to God". So, we need to not stop obeying this. If we stop making requests to God, we are disobeying Him and His word.
And so, who would want us to do an experiment of not doing something God wants, for a full year? Who is the one who "dares" us to try something that God does not want?
Our requesting is included in our relating with our Father and Jesus.
In case you mean something else, then we aren't doing what you mean, anyway

So, how can we stop what we're not doing?
And maybe to answer your question, even so - - - each day, a number of us find out . . . the hard way . . . what becomes of us if we do not pray all through the day. When we get away from being prayerful, we get in messes in our emotions and feelings and strayed thinking which brings stinking and trouble and confusion and frustration and hurts and unforgiveness . . . because we got away from being prayerful "in love". We need God, every moment; prayer is keeping in touch
And church is a time when I am sharing with my brothers and sisters in Jesus. It is not only a practice with copy-catting. My people help me get correction and their example so I can find out more how to love. I would not want to be away from these people and the way I can become by myself. I spend time by myself, each day, and it can be messy.
But I think, in my church, we need to be more into praying with each other; this I am concerned about. The prayer that we do do together is not really requesting, but trusting, and claiming how we need correction and more growth in love, asking for how we relate more and more intimately with God and each other and show His love to any and all people; this is what we pray and hear in our preaching; I definitely need to be there to be confronted with this, reminded of this, and encouraged to keep after this, and to be sharing with others who are into this, too. So, going a year without this . . . no way!!
Though they are not perfect about having prayer together, but they are so good for me, as my example of being real with God and relating with people caringly with unconditional love. So, I desperately need to spend time with them. But during the week they have families and lives and jobs to take care of; so Sunday is my practical time to be with them.
God is our Father > His name shows He is about family. So, He does want us to spend time with each other, as family. Sunday church is an opportunity for us to be family with each other. Our requesting things in prayer, then, is something we can share in doing, as family. We care about each other, in prayer, not only about ourselves. So, the caring of our requesting is important; it would not be good to stop caring in prayer, for a year.
