This! There are so many better sources of info than Jack. Now I am very lucky in that I am comfortably off now but I grew up in a house where there were lots of kids and not a lot of spare cash so my mum was extremely clever at making good food for not much. Because of that I'm always interested in frugal food and I'm in a couple of Facebook groups to do with living on £1 a day and another one about surviving on 50p a day for when the
tit really hits the fan. Those groups are full of brilliant advice, recipes and fully costed meal plans for a month for people who need them, even helping people to build a store cupboard over time. On top of that there is so much love and encouragement for people who are struggling and asking for advice. There is no slop to be seen.
There are also loads of blogs too dedicated to helping people do budget meal plans etc. Has Jack ever actually done any meal plans? The way she talks it's like no-one else has a clue and she's there to save them - really, really gets my goat.
