Food

Food and Water are survival mechanics in Subnautica 2. They are stats which steadily deplete when playing on Survival Mode. The player must maintain their hunger and thirst levels by consuming food and water items. If either stat reaches zero, the player will lose health until they die.

Sustenance is a category of consumable items crafted from certain Raw Materials and fauna using the Fabricator. While fish can be eaten raw, using the Fabricator will increase their nutritional value and remove their dehydration penalty.

To consume an item, press the "Use" keybind while the item is selected in the PDA. Some foods will also heal the player when consumed.

Mechanics

The player's current food and water levels are displayed as gauges alongside their Player Health and Oxygen meters in the bottom left of the HUD. The gauge corresponds with the stat's current value, which ranges from 0 to 100 points.

In Survival, the player loses 1 unit of water every 15 seconds, and lose 1 unit of food every 21 seconds, unless they are using the Slow Metabolism biomod, which doubles the time to 42 seconds.
