the argument that you can't afford to help your children lose weight doesn't stack up. Porridge, eggs, lentils, soup and many other food staples are cheaper than ready meals, treats or takeaways. It isn't about time or cooking from scratch either. Porridge in the microwave, an omelette, baked potato in microwave with any topping.... There are lots of nutritious meals which can be batch cooked and reheated or made from scratch in 15 mins. Water is cheaper than fizzy drinks and juice.
Again though it comes down to having f access to these staples in the first place and then having the know-how and capability to make something with them, the money on the gas/electricity to run the cooker or microwave or keep the fridge-freezer going to store the batch cook. Kids not used to lentils and soup and porridge aren't going to suddenly start eating them so wasting food and money becomes an issue too.
There was one if those benefit bashing TV shows on ages ago that showed one of the people spending their very last £5 on a large kebab and chips leaving then with absolutely no money for the two days running up to their next UC payment. There was a thread here where people were going on that this £5 could have bought a bag of rice, a bag of pasta, fruit and veg super six from Aldi, 2-3 tins of chopped tomatoes, a loaf of bread, possibly a bag of frozen veg too. However the person on the show didn't have access to an Aldi or other supermarket and only had enough money on the meter for the lights with no top up for cooking, so the large kebab and chips was hot, available, could feed the two of them for their dinner and then the leftovers would feed them the following day too.
I know its been said on the thread that there is no excuse for not looking stuff up or figuring out a way to make nutritious meals on the cheap but there really are adults in this country for whom that is beyond their capability. Who don't know what the fuck they would use porridge oats for or who would consider lentils to be too confusing. Adults raised in chaotic households who then go on to lead chaotic lives of their own aren't suddenly going to get their shit together enough to start making soup from scratch.
In the year 2018-2019 the Trussel Trust food bank issued 1.6 million food parcels, a figure they expect to beat this year. The parcels contain food that is designed to be easily cooked considering those in food poverty are also likely to be in fuel poverty. The groups try to make the parcels balanced however they don't usually contain fresh produce as items need to be non-perishable and there is a reliance on heat-to-eat items such as pot noodles, pasta meals, tinned meat, etc. which typically have a high calorie and fat value. This is again something which impacts upon overall health.
There are many issues around social and financial inequality that tie into health
