InvokeRepeating help

Hey everyone, i have a problem with InvokeRepeating and variables. I have a float called hunger, and im using an InvokeRepeating to make sure the hunger float decreases every x seconds. This works fine, but what i want is for it to decrease even faster if i hold down a button. Therefor, i obviously use variables, which you can see in my code below. When i press said button, i can see the variables change in the inspector, but the hunger float is actually not decreasing any faster. Is this some sort of limitation w/ InvokeRepeating? Or is something wrong with my code?

C#:

    public TextMeshProUGUI hungerText;
    public float hunger;
	public float hungerDelay;
	public float hungerRate;

	// Use this for initialization
	void Start () {
		//hungerDelay = 0.5f;
		hunger = 100;
		InvokeRepeating ("HungerDecay", hungerDelay, hungerRate);

	}
	void Update () {
	hungerText.text = "" + hunger;

	//hungerSpeed -= 0.1f;

	if (Input.GetKey (KeyCode.LeftShift)) {
		hungerRate = 0.0001f;
	}

	void HungerDecay()
	{
		hunger -= 1;
	}
}

You need to CancelInvoke and set it again after changing variable.

if (Input.GetKey(KeyCode.LeftShift))
        {
            if (hungerRate == yourBaseRate) // to make sure instruction will happen only once
            {
                CancelInvoke("HungerDecay");
                hungerRate = 0.0001f;
                InvokeRepeating("HungerDecay", hungerDelay, hungerRate);
            }
        }
        if (Input.GetKeyUp(KeyCode.LeftShift))
        {
            CancelInvoke("HungerDecay");
            hungerRate = yourBaseRate;  // so you can set to "not holding" variable.
            InvokeRepeating("HungerDecay", hungerDelay, hungerRate);
        }

I would do something like this:

 public TextMeshProUGUI hungerText;
     public float hunger;
     public float hungerDelay;
     public float hungerRate;
     public float originalHungerRate;
 
     // Use this for initialization
     void Start () {
         //hungerDelay = 0.5f;
         originalHungerRate = hungerRate;
         hunger = 100;
         InvokeRepeating ("HungerDecay", hungerDelay, hungerRate);
 
     }
     void Update () {
     hungerText.text = "" + hunger;
     //hungerSpeed -= 0.1f;
     if (Input.GetKey (KeyCode.LeftShift)) {
         CancelInvoke();
         hungerRate = 0.0001f;
         InvokeRepeating ("HungerDecay", hungerDelay, hungerRate);  
     } else if (Input.GetKeyUp (KeyCode.LeftShift)) {
         CancelInvoke();
         hungerRate = originalHungerRate;
         InvokeRepeating ("HungerDecay", hungerDelay, hungerRate);
     } 
     void HungerDecay()
     {
         hunger -= 1;
     }
 }

I don’t know entirely if this works or not but maybe it will.
