How to Read the Saturation and Exhaustion Bars

In vanilla Minecraft, hidden mechanics govern how quickly your hunger depletes and how effectively you regenerate health. The SATB Data Pack makes these invisible stats visible on your HUD by adding the Saturation Bar and the Exhaustion Bar, allowing you to time your meals much more efficiently.

Understanding the Saturation Bar

The Saturation Bar acts as a secondary hunger bar. It shows exactly how much saturation buffer you have left before your standard vanilla food bar starts to decay.

1. Watch your Saturation Bar after eating food. Different foods restore different amounts of saturation alongside standard hunger points.

2. As long as you have visible progress on your Saturation Bar, your main hunger bar will not drop, nor will it shake.

3. Hold off on eating high-value foods until your Saturation Bar is low to avoid wasting saturation points.

Tracking Action Drain with the Exhaustion Bar

While saturation shows your food buffer, the Exhaustion Bar shows the immediate progress toward losing your next point of saturation or hunger.

1. Perform strenuous actions such as sprinting, jumping, swimming, mining blocks, or attacking mobs.

2. Watch the Exhaustion Bar progress as you perform these actions. It directly indicates how long it will take for either your Saturation Bar or your food bar to decrease by one unit.

3. When the Exhaustion Bar reaches its limit, it resets and consumes one point from your Saturation Bar—or one point from your food bar if your saturation is already completely empty.
