The 30-year-old, who signed from Reading during the transfer window, has endured a slow start to his Elland Road career and was substituted within an hour during United's 1-0 loss to QPR in the Championship last time out.
Hunt was the first to acknowledge his below-par performance as he told fans on Twitter; "I'm an honest lad who always tried to play with my heart on my sleeve! And pride in the shirt! And lets be honest I can only get better!"
However, despite failing to score in his first four outings, former Royals manager McDermott insists he has faith in the Republic of Ireland international.
"Noel is an honest guy," the Leeds boss told the Yorkshire Evening Post. "He is probably down on himself too much at times.
"But I have seen what Noel has given teams I have had in the past, which is an awful lot, on and off the pitch.
"He wants to do really well for Leeds. He knows himself - especially in the last game he played against QPR - that he didn't do himself any justice.
"I didn't need to tell him that, he knows that himself. I thought against Ipswich in the game before, he was very, very good with him and Luke Varney up front doing really well away from home. No-one needs to tell Noel, he knows himself."
