How to make a variable decrease every five seconds?

Questions & Answers
1

So, right now my hunger code is;

timer=Time.deltaTime;
	if(timer>10) 
	{
	Hunger-=1;
	HungerReset();
	}

But I want Hunger to decrease every five seconds. Any ideas?
If I left out any important information, let me know.
Okay, so none of the suggestions worked, but thanks for trying.
My new code is:

#pragma strict

var Hunger:int;
var MaxHunger:float=1000;
var timer:float;

function Start () 
{
	Hunger=MaxHunger;
}

function Update () 
{
	timer=Time.deltaTime;
	if(timer>10){
		function Hunger();{
			for(i=Hunger;i>0;i--) {
				yield WaitForSeconds(5.0);
							 }
						  }
				}
}

The only problem is that Unity says:
Assets/Hunger.js(16,26): BCE0044: expecting (, found ‘Hunger’.
Does anyone know why?
Thanks!

Coroutines work well for consistent operations.

    void StartHunger()
    {
        StartCoroutine("HungerCounter");
    }


    IEnumerator HungerCounter()
    {
        while (true)
        {
            yield return new WaitForSeconds(5f);
            Hunger-=1;
        }
    }

float timer = 0f;
if (Time.time > timer)
{
Hunger -=1;
timer = Time.time + 5f)
}

You haven’t given a lot of context (and I have no idea with HungerReset() does). But making some assumptions, you would modify your code this way:

timer += Time.deltaTime;
if(timer >= 5.0) 
{
    timer = 0.0;
    Hunger-=1;
    HungerReset();
}
