How to start modding

I was thinking of making some Minecraft mods (Java, 1.20.1) but I've never tried or come close to making a mod or anything like that so I'm a complete beginner and it looks so hard lol, But I know programming in C# so I wonder if it would be hard to learn Java and if I can have some tips on how should I start?

Rapid hunger drain in nearly 300 mod modpack

I'm playing with a 300 pack (290+) modpack and after using the icarus mod i started getting a crazy hunger drain. I uninstalled the icarus mod and it still persists I have no effects, I'm not running, I have nothing but grapes and carrots in my inventory, no armor. But this KEEPS happening (Mod list in comments)
