Ghoulvolution - Glow Meter Explained
When you become a Ghoul, your Food and Drink meters disappear and are replaced by the Feral Meter. However, food and drink buffs still function as usual.
For example, If you have the Herbivore mutation, you’ll still receive the Strength buff from Steeped Fern Flower Tea, and if you have the Carnivore mutation, you’ll still get the Melee Damage bonus from Tasty Mutant Hound Stew.
In the game's backend, your Food and Drink levels are permanently set to 0 (starving). Because of this, perk cards like Rejuvenated and armor effects such as Overeater's are disabled.

The Feral Meter has 7,200 points and drains at a rate of 1 point per second, meaning it takes 120 minutes (2 hours) to go from Full (Wonderful) to Empty (Feral).
To keep your Feral Meter full, you need to consume chems, as different chems replenish the meter by varying amounts. A full list of chems and their effects can be found [here].
Once you complete the Ghoul questline, your stats and perk cards may be disorganized, so having chems on hand is a good idea. Psycho is a strong choice to help balance your build while you get everything sorted.
Note:
The Healing Factor mutation does not affect the percentage of Feral gained from chems.
Equipping Class Freak does not affect the rate at which the Feral Meter drains.
