I think you need to take claims on here of very high/very low bills of any kind with a large pinch of salt. The cheaper ones tend to “forget” to include eating out and takeaways! Which is cheating in my opinion! On “eat well for less” there are often families that say they “only” spend ‘seemingly tiny amount’ at the supermarket - but then the presenters jump in and say “ah but you spend £200 a week on takeaways!” I bet they also spend a fair amount on fancy coffees out and about and don’t include them - It’s misleading - I also wonder if these people are including all groceries as I suspect you’re also including cleaning materials and toiletries and they maybe aren’t?
It CAN be done but it’s not easy and not much fun!
However that being said, as I am someone on a tight budget and who tends to the frugal I would suggest the following, some of which have already been suggested:
Meal plan - not just for dinners EVERY meal and have a good idea on snacks and drinks too you really shouldn’t NEED to be doing top up shops - supermarket psychologists/designers LOVE top up shoppers as they spend far more than strictly weekly shoppers! Supermarkets spend a LOT of money on experts who tell them exactly how to extract more money from customers!
Fruit and veg - if you’re buying “fancy” your costs will be higher, apples, bananas, potatoes, carrots - the more “traditional” British diet is cheaper than berries, aubergines and sweet potatoes!
Drinks - often ignored on such threads - are you drinking loads of bottled water/cans/ready made drinks? Maybe looking at cutting these down. Tea, coffee and Squash tend to be cheapest options
Food waste - something we’re all guilty of at times - are you using it all or throwing a lot away due to lack of planning?
Meat eaters? - I’m veggie and I’m
Shocked when I see the price of meat! Veggie eating is much cheaper, try and do so at least a couple of times a week, mac n cheese or a veg stew doesn’t mean you’ll feel you’re “missing out”. Also bulk out meat dishes with veg - tends to make it lower fat/lower cal too as you’re trying to lose weight.
Shop around - supermarkets are stupidly expensive for cleaning products, toiletries, stationery etc yet many of us fall into the trap of buying these there for convenience. I’ve found places like wilko, b&m and home bargains are much cheaper for cleaning products etc
Also some supermarkets are more expensive than others - I’ve shopped with Sainsbury’s in the past happily but their prices have definitely shot up in recent months!
Shop savvy - bulk buy, make the most of offers, get and use loyalty cards, keep an eye out for vouchers - eg I only like fairy original but I NEVER pay full price, when I see its on offer I stock up, ditto baked beans - I shop with Tesco and they’re on a “4 for” on a regular rotation, it’s only me here so I don’t get through loads but I stock up as they have a long shelf life, this week I’ve treated myself to a couple of new electricals which I needed anyway and were on my long term “to buy” list because Tesco currently have an offer on of £5 off if you spend £40, ok not a huge amount but as they say “every little helps” I also checked the price of the items with other retailers just in case they were higher priced anyway and found other retailers were selling at a higher price so definitely worth buying from Tesco in this instance.
Food ALONE just for me I’m around £35 - 40 and I only eat one meal a day and a snack! No alcohol but I am tending towards higher quality as my way of “treating” myself - if I had to I could cut it down to £15–20 by switching to all basic brands
I’m agoraphobic and this is my only pleasure really at the moment plus I need appetising things to motivate me to eat as I’m really struggling with that at the moment.
If you can afford the way you shop it’s your choice.
