Last year, the final series to air on the BBC earned a huge 10.4 million viewer ratings, which hit a peak of 11.2 during the episode.
It pulled in Channel 4's best ratings in five years - the last time being the opening ceremony of the Paralympic Games in August 2012.
"This show breaks even at around 3 million, so anything north of that would be fantastic", said Hunt, adding that if it reached between 5-7 million viewers she would be "absolutely delighted".
But, it turns out, this is a drop of nearly 4 million when compared to the previous series of the show.

Robins Farm on Latham Road will give a slice of homemade cake to anyone who orders a main meal between 5pm and 7pm, just a few hours before the hugely-popular baking show premieres on Channel 4.
The number of Channel 4 viewers is expected to increase significantly with on demand streaming over the next seven days, as it has for the BBC in previous years. Channel 4 also signed two sponsorship deals for the show worth an estimated £4 million ($5.2 million).
Great British Bake Off starts tonight and we're getting all our eggs, flour and cookie cutting implements ready and in a row.
The departees will be replaced by judge Prue Leith and Sandi Toksvig and Noel Fielding - the Mighty Boosh star who admits he doesn't eat cake.
The average peak-time price for a 30-second slot on Channel 4 is around £100,000; however, the broadcaster is charging between £150,000 and £200,000 to advertise within the 8-9.15pm Bake Off window.
