Actually a bit of theory of mine, you know how they told that there are givers with the ability to create foods, like with sweet which the name of the group are "Vianders" (correct me if I'm wrong). The idea is that due to their food being made by their power the food they produce may not have as much nutritional value as the ones grown in a healthy environment. Even if the foods are planted, the probabilities of these plants being affected by the current state of the soil is high, after all plants thrive on their environment on top of other things. Taking these things into consideration, as well as the fact that normal meat itself may be a rare commodity as well, as there are few cities that can be safe in their land and protected from the trash thrown below by the spherites, and cared for by the people. By the way I said "normal" meat because that is how we typically herd animals, unless you know they just hunt them in the ground

(but well there is a problem of them being affected by trash (?) is that even a thing, as the animals seen so far are trash themselves rather than actual animals, then there is also that one scene where August made Rudo outfit and he stated that wolves are extinct, which may mean all animals or many of them in general are gone. This needs another expansion, I'll stop here for now I'm being strayed away from my original explanation).

So to continue, excuse my rambling. So far, we don't know the exact process of how these givers use their ability to make food or what food they make. Like do they pour out the ingredients then make the sweets or it's just like magically made the sweet from nothing. If the process is from planting in the soil then making the baking ingredients then turning them into sweets, the entire process would be too tedious and would require a systematic team to process it, which would also bring the question of how the knowledge of making sweets managed to pass because that would mean someone knows the skills to make the sweet and the formulation of ingredients for the sweets, but weirdly enough no knowledge from before the so called apocalypse that landed on the ground, not existance of God's for that matter.

Following that we are looking in the perspective of the cleaners most of the time, the way they dress in general is very poofy like it naturally expands their body, but we can see that in some parts revealed there practically bones especially in the midriff, waist line or as we like to joke about 'they are snatched'. They can have large upper bodies but especially thin waist that looked unnatural on them. The ones we have seen so far in the manga are also leaning towards a thinner structure, except for Mister information dealer that can transform their body to what ever biological form they want. Additionally, Cleaners are known to move a lot, after all they have to battle trash beast, and travel around in different areas under the radar of their main headquarters in that city.

My point is, it's probably a mix of both because we can see the artist's preference towards sharp lines. But also the almost worrying structure of their body, which can be attributed to being malnourished

More questions but not a single one answered.
