Low UPF diet - to think the experts weren’t lying?

Nearly 6 months ago I made it my New Year’s resolution to start eating a low UPF diet in hopes of losing some weight for a once in a lifetime trip, alongside just being healthier in general. Honestly it has been life changing! I’ve lost nearly 10kg without really having to think about it - no restricting or anything like that and in general I just feel so much better. UPFs like crisps, ready meals, even basic supermarket bread don’t feel like ‘real’ food anymore and no longer appeal. On the occasion that I do choose to eat something UPF (which for me is no big deal, im not strict!) it just isn’t as enjoyable as it used to be. I’d choose some sourdough over a loaf of Hovis any day when previously I used to hate it! I feel much fuller + satisfied for longer and rarely get the urge to snack.

Obviously it has its downsides - much less convenience food so cooking takes longer (PITA when doing lunch/dinner prep after a long day at work!), ingredients are more expensive so my shopping bill has gone up but all in all it’s a decision I don’t regret. Honestly I think that this way of eating should be the future.

Anyone else feel this way?

I agree with you OP. I was quite poorly a while ago and changed my diet to mainly cooked from scratch meals. It has made a huge difference. Big disadvantage for me is the time it takes but I have persevered. I wasn't a great cook either but have got better. I find it cheaper too, mainly because I add enough veg or pulses to make things go further. I do eat chocolate but in moderation.

I also think smoking kept people thinner in the past!

It's basically good nutrition and biology, and eating junk with no nutritional value won't fuel your body properly.

My DM has always cooked nutritious and good food from scratch, with the odd treat. She's been as healthy as an ox, living well and she's probably going to get to 85 the way that she treats her body.

And I know that she probably has been doing for my benefit too, to ensure I got the best start being a prem baby.

And I know that she literally always was telling me about the awful toxic crap in things like artificial sweeteners, diet drinks etc. Now that I'm oversensitive to all that stuff more since being harmed by an off label antipsychotic (that gave me a permanent neurological involuntary movement disorder called tardive dyskinesia), i realised that I should have listened to her ever-growing wise knowledge years ago. My body definitely agrees with me more when I feed it "proper" real food.

I do love crisps.

Bread is easy. Rolls/buns in a bread maker, for example, are simple, or just follow the recipe on the side of the bread packet.

Sourdough discard is also great for baking if the actual sourdough fails. Try heartbeat kitchen or vindi's kitchen for recipes.

My Grandparents grew up eating lard and butter and bread etc, most women didn't work, exercise outside of cleaning was rare, but so were fat people.

People may not have been morbidly obese but there were definitely fat people. I think a lot of it is sedentary jobs & cars.

I did state that the correlation is between obesity and introduction of UPFs, in fairness.

I do remember seeing 'portly' people in the 70's but again, it wasn't common.

The data doesn't lie - we starting getting bigger, at alarming rates, as soon as the UPFs arrived.

JustSawJohnny · 06/05/2025 22:00

The biggest change for me (outside of weight loss) has been less migraines, better sleep and a reduction in symptoms related to my auto immune disease.

I'm also not sensitive to gluten any more (likely related to the increased control of my AID, as when this is really out of whack my sensitivities worsen).

I can't believe how disgusting white bread is now - I bit a McDonalds burger last week and it felt like foam in my mouth and went all gummy when chewed. Vile! Also how sweet Diet pop is. It's truly disgusting.

I don't miss most of the things at all but do admit to a bit of chocolate each night (sometimes UPF free) and the occasional utterly disgusting cupa soup, because Oh the powdery goodness 😂

I agree that you still have to have a life and eat out etc, but the small changes do make a difference.

I agree, I’m really committed to eating low UP food. The biggest hurdle is getting my kids fed, they look for snacks so much, so trying to bake stuff and look for crisps with the lowest number of ingredients. But the snack bars are full of crap! I figure home made cake is much better!

Cereal is the other big problem - trying to make homade breakfast muffins.

Some good snack options we buy:

  • Crosta and mollica snacks such as breadsticks / tarralini etc
  • we got a ‘dehydrator’ from Amazon and make our own fruit and vegetable crisps!
  • cut up non UPF wraps and homemade natural yoghurt dip

reminder to all to avoid anything at all with added ‘flavour’

EG if you buy yoghurt get plain, Greek yoghurts etc nothing flavoured

I find M&S soooo upf heavy unfortunately! I’ve never bought their sourdough though is it nice ?

I like it, prefer Jason’s but it’s like gold dust these days! I really just buy fresh produce in M&S as I find it’s higher quality and lasts longer. I do agree though that their aisles are packed with far too many ready meal type things and UPFs!

My only real downfall is chocolate. I am absolutely addicted to sugary milk chocolate, just standard galaxy etc. dark doesn’t hit the spot!

JustSawJohnny · 06/05/2025 21:53

Gattopardo · 06/05/2025 21:06

Well yeah, it’s basic nutrition though. Eat more whole foods, home cooked stuff, less convenience food. It’s healthier: there isn’t any evidence for the specific mechanism whereby UPFs are apparently unhealthier. It’s just they are inherently higher in fat, salt and sugar and denuded of nutrients. I think the whole UPF thing is emperors new clothes to be honest

Edited

The thing I can't get past is the data from literally all over the World that shows the introduction of UPFs to the market and a sudden rise in obesity. The correlations are truly frightening.

My Grandparents grew up eating lard and butter and bread etc, most women didn't work, exercise outside of cleaning was rare, but so were fat people.

I just don't buy that it's a coincidence that a high percentage of any population just decided to get lazier and over eat all at once.

Plus these companies don't hide the fact that they spend millions every year developing recipes that ping the addictive parts of our brains so that we crave their products and become return customers.

More like common sense than Emperor's new clothes, for me.

Cereal you can have Bear (sometimes in the kids / toddler section) cereals

they do a honey flavour and a ‘chocolate’ flavour

6 ingredients

remember to try and buy full fat milk (even better if in cardboard packaging or glass)

you want to avoid plastic packaging as much as possible x

We mainly stick to good sourdough (I find Jason’s & M&S from the bakery to be the best). Re: wraps Mission Deli taste great and have the least ingredients out of any others available in a supermarket

I’d love to start experimenting with making my own breads but I’m afraid that I just don’t really have the time or energy!

Edit: just looked at the Mission ingredients list and they’re not as good as I thought! Back to the ever increasing drawing board..

Any tips for bread products?

Waitrose own brand, Celtic baker, seven Seeded, Jason’s

wraps etc: only none UPF is Crosta and Mollica

you want to find things that have no rapeseed oil or any E numbers or gums etc

I’m glad that DD is grown up now as I can imagine how difficult it would be with young DC, especially re: snacks and school lunchboxes. At 21 she happily makes better nutritional choices than I did for the vast majority of my life and is actually the one who nagged me into going low UPF in the first place! 🙈

O’Donnells crisps are the best! Proper hand cooked ones with very few ingredients. Their Irish sea salt & vinegar is absolutely amazing. Re: breakfast we mainly stick to Weetabix & fruit - not the most exciting but it’s easy and does the job.

I make and freeze wraps which are really easy and nice, and also pizza bases and flatbreads. Not very good at making bread but can manage those.

Completely agree OP, I read Ultraprocessed People by Chris Van Tulleken and I completely changed the way I view food and how I eat.

I feel so much better and had previously suffered from an auto-immune condition that I now don’t need medication for. I have so much energy it’s ridiculous and no more energy dips. It’s changed my life.

I read it and was unimpressed to be honest. The basic premise is as old as the hills and the actual
science on UPFs (ie what specifically it is about UPFs that causes ill health) is very weak indeed. People have been concerned about additives for at least 50 years.

Yes, it's criminal. It's no different from the tobacco companies pre-anti-tobacco legislation. This idea has been out there for a while, and there is a substantive body of experts calling for meaningful reform. However, when you're up against the giants of food production - and they're titans - no small-person lobbying can hold a candle to these hundred billion (not an exaggeration) dollar organizations.

All you can do is educate yourself, and lobby for change when it comes to schools and those below the poverty line. Good food is expensive. Terrible, poor quality food, is cheap. Ergo, the poorest suffer the most. Same as it ever was.
