On a micro scale I would encourage people to read [https://www.amazon.com/Happy-Are-You-Poor-Spiritual/dp/0898709210](Happy Are You Poor) because often we ought to be living a simpler life, for reasons beyond its impact on the planet (yet it does also have an impact on our brothers and sisters and on the rest of creation.)
I recommend reading https://www.amazon.com/Happy-Are-You-Poor-Spiritual/dp/0898709210 before deciding on an answer.
Note that you can be hungry and poor and not get into heaven (if you decide to commit mortal sin and to not repent, you are probably not going to heaven unless you change course) so there is something different going on than just hunger and poverty.
Yes, Catholics are encouraged to make greater sacrifices as they grow spiritually. Take, for example, Fr Dubay's Happy Are You Poor. He discusses levels of radicality in living the Gospel.
Just a note about spiritual direction in the Catholic Church, especially in a diocese like mine. We have 1 priest for every 6,229 Catholics. As you can imagine, our priests have a hard enough time just getting us access to the sacraments (Eucharist, confession, last rites, etc). Some spiritual direction is offered in confession, but often it isn't. It can be very difficult to find a priest or a deacon to act as a spiritual director, so one often has to depend on strong spiritual friendships and good materials to help.
There are Catholics who are trying to make greater sacrifices in their lives and prepare for the great feasts, but it is slow going. For example, many Catholics do not realize that Advent is a penitential season in preparation for Christmas (our priests vest in purple, a penitential color, and also used during Lent). I suspect that they have been influenced by the culture and it's emphasis on the "Christmas shopping season." Take my analysis with a grain of salt, as it is far more complex.
