New Year's resolutions about food often involve cutting down on something, or giving something up, but how about committing to trying something new for the next 12 months? How much harder is it, and what do we learn about ourselves along the way?

Graihagh Jackson meets three women who went to extraordinary lengths in search of change: a working mum who cooked a different meal every day of the year to escape a cooking rut; a writer who made her own salt from seawater and learned how to butcher a sheep as part of a pledge to only eat non-processed foods; and a blogger who logged and photographed everything she ate for 365 days.

We hear how difficult, expensive and exhausting the challenges were, but also how they brought each of these women closer to their families and friends, as well as their food.
