Eat Well for Less? - Season 4

Gregg and Chris have a challenge on their hands with the Rielly family from Middlesex, whose plentiful problems lead them to explore carbohydrates - should we be trying to cut them out of our diet or not? Chris investigates the baffling difference in price between cheap table salt and high-end sea salt to find out if it is ever worth paying more. The Riellys are a busy family with very different eating habits. Dad Adam lives on takeaways whilst mum Stacy cooks three different dinners every night because she and the kids do not like the same foods. Twelve-year-old Izzy is so fussy she survives on tomato soup and pasta, whilst eight-year-old Harry has type 1 diabetes, so Mum has to count the carbohydrates in everything he eats - not easy when Harry snacks up to eight times a day and is always hungry.

Can they keep the Caan family from Glasgow, mum Tina, dad Ryan and kids - six-year-old Laila and eight-year-old Ray - away from their favourite takeaways and get them cooking from scratch? Gregg and Chris meet dietician Hala El Shafie to see what's really in some of our most popular takeaways, while Chris investigates what supermarkets are doing to tackle food waste, and helps the Caans try and overcome their wasteful ways. Ryan is addicted to food shopping and loves his fridge to be full, but with a weekly visit to the supermarket, a trip to the butchers and top-up shops every other day, this family's food bills are spiralling out of control. When it comes to food, convenience is king in the Caan household with takeaways being a weekly staple.

Gregg Wallace and greengrocer Chris Bavin help families across the UK sort food fact from fiction and eat well for less. They have come to Nottingham hoping to help the Brook family, who are well and truly stuck in a rut. Tourism lecturer Janine is at her wits' end with husband Paul and their two girls, Rosie and Sophia, all of whom prefer snacking on sugary treats to following a healthy diet. Having quit sugar two years ago, Janine's hoping that with a little help, her family can reduce their dependence on the sweet stuff. As the girls are fussy eaters Janine relies heavily on 'quick teas', convenient favourites she knows her children will eat. Janine feeds them separately to her and Paul, but this means she's cooking twice a night and churning out the same old meals. Janine has secondary breast cancer and having exhausted all treatment options on the NHS is now faced with self-funding the drugs she may need in future, and so every penny this family can save really does count.
