Mod coding help for glowing character, durability decay, and calorie burn?

[Lacuscanidae]

(Apologies if the title is a little too lengthy!)

I have very little experience with coding, and fairly new to the modding world for any game (creating mods anyway.) I'm designing a character for my brother and was wondering if the possible things could be achieved:

• Hunger drops by a noticeable amount points at once after a certain amount of time. (Ex. 10 calories lost immediately after x seconds instead of gradually.)
• Character glows slightly at night when Hunger is above a certain value. (And to possibly negate this glow when the character sleeps.)
• Durability of head items decays much faster than normal. 

Ambitious for a newbie, I know, but I have a vision and I want to see it through, game limitations allowing. Any feedback would be greatly appreciated!
