About
Metabolism overhauls Minecraft’s hunger system with linked temperature, food, hydration, warmth, and health mechanics that make survival and exploration more consequential. Environmental conditions such as hot or cold dimensions, snow, water, altitude, darkness, and hot or cold blocks shift your heat, while sprinting can add heat; heat drains hydration when you are hot and food when you are cold, and can make health regeneration harder. Shelters, nearby campfires, and suitable armor provide warmth or temperature resistance, with ordinary campfires helping against cold and soul campfires against heat. The vanilla food bar becomes a warmth bar, which fuels natural health regeneration, while a new HUD tracks food, hydration, metabolization progress and results, and heat-driven resource drain. Eating supplies food and hydration, and metabolization converts these resources into warmth; when the bars are unbalanced, it can instead convert the more plentiful resource into some of the one being drained. Mining, walking, sprinting, swimming, jumping, attacking, taking damage, and breaking blocks build metabolization progress rather than directly causing the usual hunger exhaustion, and certain foods add a metabolism effect that speeds up that progress. Food choices have distinct uses: stews offer food, hydration, and warmth; cooked meats mainly provide food, baked potatoes offer a more balanced mix, and golden foods help restore warmth quickly, while fish, vegetables, fruit, sweets, and some environment-specific foods have different resource profiles. Food tooltips show their food, hydration, and metabolism effects, and the mod changes some eating and stacking behavior, including stacking stews and soups to 16 and cakes to 64. Datapacks can configure environmental effects, resistances, and food data, and can add or change effects and metabolite values; foods from other mods also receive default food, hydration, and warmth values. The mod includes compatibility for Pagan’s Blessing and Create.

Security
No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.2 latest files: the newest file for each Minecraft version and loader. Both are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of both files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign so far that AI was used to make it
We looked for AI tools in its description, files and images and found none.
We have not read its changelogs and code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found in the descriptionChangelogs not read yet
