Wut? ... Fascism constantly had rationing. Germany, Spain, Italy, and Japan rationed everything: bread, chicken, beef, rubber, steel, iron, tin, etc. Even if we say, "dude bro, that was only because of the war", they still had rationing. This is because they also had price controls. If you have price controls without rationing, you'll get massive shortages and over-supplies, so you have to ration people's purchases. Yes, I'm including Germany's National Socialism and Japan's Ethno-Militarism in these because they are still significantly overlapping for our purposes.

And, mother of God, do not ask about Fascist occupied territories. The Axis countries plundered and rationed Greece and Crete nearly to the death of the whole population. Even the puppet governments were horrified to the level of plunder and starvation that was taking place, such that they contacted the Axis command with a dire warning: "Send us wheat or coffins".

Fascism and War-Time Stalinist Communism have a ton in common. Being that both are Left-wing ideologies and are explicitly extensions from Socialism: Stalinist War-Time Communism is a kind of Nationalized Marxist-Leninism which is a final position for Socialism to achieve after Bolshevism; and Fascism is literally "Trade Unionism", but is understood as a Italian State Syndicalism. Many (Trotskyite) Leftists have called Stalinist Communism "Red Fascism" as a way to distance themselves from his crimes, but they are accurately pointing out a significant overlap.

Fascism and Communism do have some differences, but they can be easily boiled down to: Fascism is a practical application of Communist values, where Communism is an ideological adherence to Communist values using the state and party as the vanguard of a revolution.

Now, Fascism and Bolshevism have a lot more structural differences, but only because Fascism is operating from a single top-down strata, and Bolshevism operates off of the tyranny of the local committee (or Soviet). If Fascism is the practical application of Communist values, then Bolshevism is the totalitarian adherence to Communist values to the point of nearly suicidal, perpetual, revolutionary, warfare. The economic objectives are all still exactly the same, and rationing is part of that.
