3.1. Intervention Acceptability
3.1.1. Burden and Opportunity Cost
Sub-Theme: User-Friendly Process
“It was very easy to use, straightforward, step by step process. You could easily work your way through it.”—Participant 15, female, healthy BMI.
Sub-Theme: Concerns about the Ordering Timeframe
“I suppose in terms of the service that we offer, we all work different shifts. So, I don’t know whether it would be something that you would have to be in the office to be able to access that platform, or whether it’s something you can maybe even go on your phone or something in the morning?”—Participant 21, female healthy BMI.
“I probably would [use it]. I think there needs to be some kind of prompt. I think quite a lot of people, if you go in to work and you’ve got a meeting straightaway, you might need to, as I say, get a prompt. You might forget to order.”—Participant 26, male, healthy BMI.
“I would want to order a little bit closer to lunchtime for that, just to know what I feel like.”—Participant 4, female, healthy BMI.
“On a Monday, I come in, book my desks for three weeks in advance. So, on Monday you’d make it as part of that. But even then, on Thursday and Friday, you make it as part of your morning routine.”—Participant 28, male, overweight.
Sub-Theme: Preference for Visual Decision Making
“I don’t think I’d like that [pre-ordering], especially with our canteen. I think I’d like to see the dish or at least have a photo or something, or a good description of it.”—Participant 19, male, healthy BMI.
Sub-Theme: Desired Service Logistics
“I think if I was made to pick a timeslot to go and get my lunch, it would force me to take my lunch at that time. So that’s good, in that sense.”—Participant 29, female, overweight.
“I would rather it be made ready for collection when you get there, because you don’t just want it on a plate sat in some warmer somewhere.”—Participant 23, female, obesity.
“I’m just wondering, what have I actually gained here? I’m presumably going to still be in the same queue as people who haven’t pre-ordered…If more than half the population of [the company] start pre-ordering, then I could be in a longer queue to pick up pre-ordered meals than I would be for not pre-ordering.”—Participant 25, male, overweight.
“As long as you don’t have to join the normal queue where they’ve not pre-ordered, because obviously then it defeats the purpose. If you get seen straight away, then I think that’s absolutely fine.”—Participant 26, male, healthy BMI.
“The benefit of it for me is that nothing would ever run out, I assume, if I ordered it. They’ve guaranteed it.”—Participant 12, male, overweight.
3.1.2. Ethicality
Sub-Theme: Concerns about Imposing on Personal Autonomy
“I think, like I say, it’s just to get you thinking about things. I don’t think it’s too personal or anything like that. Yes, I think it’s good.”—Participant 10, female obesity.
“There’s a lot of people that I work with who are really set in their ways and would feel like they were being told what to do. And I could definitely imagine complaints about it.”—Participant 1, female, obesity.
“It’s acceptable, but I’m not sure the response will be very good…It’s kind of Big Brother. It’s someone that you’ve never met, will never meet is pushing you down or prompting you down an avenue. I’d be more likely to say no.”—Participant 19, male, healthy BMI.
“What to me would be more useful is to tell you the calories and how long it would take to burn off each of these [menu items individually].”—Participant 5, male, healthy BMI.
“It might get a bit tedious sometimes, if you’re ordering this on a daily basis, and you’re going through swaps daily, and you’re saying no to it.”—Participant 8, male, overweight.
Sub-Theme: Alignment with Organisational Ethos
“Definitely yes [it’s acceptable], considering the nature of the company [healthcare]. I think it should be almost part of their responsibility to the employee to promote good health and wellbeing.”—Participant 9, female, healthy BMI.
“I think it’s something that should be advocated in the workplace because for me if you’re encouraging your employees to be healthy then give them the tools to do that job. As an employer, you can be part of that process.”—Participant 18, female, obesity.
“It’s difficult to answer [whether this would be acceptable in other companies], it depends on the culture. But, yes, I think it is. I think it’s becoming more and more acceptable.”—Participant 7, male, healthy BMI.
3.1.3. Intervention Coherence and Perceived Effectiveness
Sub-Theme: Pre-Ordering Reducing Temptation
“This would make me be a little bit more organised to get exactly what I want, rather than when you go down and you see certain things probably a little bit more unhealthy, you’re swayed by the smells and the visuals of it.”—Participant 3, male, overweight.
“For me, it’s committed me to have what I’m supposed to.”—Participant 16, female, obesity.
Sub-Theme: Appreciation for Information Provision
“Eating in the canteen is really hard, because you don’t know what the calories are with different options. That information isn’t available. So, certainly for me, it’s there now…. I can imagine, if we’ve got more information on the calories, I’d be making a more informed choice.”—Participant 14, female, BMI unknown.
“If you just choose your food off-site, you don’t tend to stop and think, do you? Whereas, with it there on the screen, each time it comes up with lots of minutes of walking, you’d probably choose at some point to swap one of them.”—Participant 2, female, healthy BMI.
Sub-Theme: Tangibility of Information Provided
“It’s quite good because it puts into perspective the calories that you’d save and the fact that it’s like 67 min walking, it makes you think about what you’re ordering and I guess how much maybe exercise and things like that… It puts it in layman’s terms that most people can relate to.”—Participant 13, female, healthy BMI.
3.2. Factors Influencing Swap Acceptance
3.2.1. Perceived Meaningfulness of Energy-Savings
“You think, do I need to have this at all? Saving 77 calories is actually, in the day, when you’re on 1300 [calories], quite a bit for something that’s just a side as well.”—Participant 16, female, obesity.
“I’m not really bothered about calories. I’d rather have the food. I’m not particularly calorie counting. It’s a nice thing to consider if you are calorie counting, but personally I’m not.”—Participant 8, male, overweight.
“I’m personally trying to lose a bit of weight, so having to do a 34-min walk, makes you think, well if I’m going to the gym later, that means I don’t have to do as much.”—Participant 10, female, obesity.
“There needs to be a bit more of a gap…It’s just 77 calories, it’s nothing…If you were saving 150 calories. Then you go, actually, yes and then you say, it’s 35 min’ walk then you say God damn that’s a lot.”—Participant 20, male, healthy BMI.
“I just would ignore it [20 min of walking saved by swapping] because I know I exercise a lot anyway. Do you know what I mean? It doesn’t impact me really.”—Participant 4, female, healthy BMI.
3.2.2. Nature of Swaps Offered
Preference for Taste Similarity
“Yes, I think that’s quite a decent swap because they’re still like a crispy snack, aren’t they? So, as long as it’s a fairly like-for-like then that’s quite a good option.”—Participant 17, female, obesity.
[swap offered was artichoke heart tacos for fish pie] “I think it’s good to have the option. I think, maybe if the swaps were a bit more similar. Say if it was another fish dish, it might be a bit more persuasive then, rather than it being a completely different type of meal.”—Participant 29, female, obesity.
“I wouldn’t swap [coleslaw for broccoli] because I would want something with a bit of sauce on it to go with the rice and broccoli which are dry.”—Participant 2, female, healthy BMI.
“Now, I probably, just because of what it is [mixed salad], wouldn’t think that would go with as well as the Asian slaw so I wouldn’t [swap].”—Participant 4, female, healthy BMI.
Preference for Matched Expected Satiety
“It’s just not as satisfying for me to swap out potatoes for broccoli.”—Participant 22, female, healthy BMI.
[Swap offered was jacket potato with baked beans for a jacket potato with baked beans and cheese]. “Yes, I feel like it makes sense, and I would much rather give up the cheese than take an extra hour’s walk.”—Participant 15, female, healthy BMI.
[Swap offered was bean salad for white rice]. “Because I generally try not to snack in the afternoon. So, I want a more filling lunch. Or, like, if I have salad, right, if salad is the main component of my lunch, I’ll get hungry quicker. And then, I’ll look to possibly in the afternoon have something like a chocolate or a coke or something.”—Participant 28, male, overweight.
“I’ll stick with the original selection, because on that particular day I would probably have a jacket potato with cheese and beans, it’s probably a day where I’m not going to have a hot meal at home later.”—Participant 23, female, obesity.
3.2.3. Lack of Opportunity for Visual Decision Making
[Swap offered was Japanese shichimi togarashi chicken for artichoke heart tacos]. “One of the reasons I picked artichoke hearts taco is I actually understood what it meant. And then saying can I go for a what, a Japanese what? So now you’re offering me something where, yes, I’d want to actually see it before I went for that.”—Participant 25, male, overweight.
3.2.4. Price as a Secondary Influence
“So, I’ve gone for the Oasis Summer Fruits. And it’s: would you consider going to the Fruits Zero, which is the same price, same flavour, sugar free? I probably would [swap].”—Participant 30, male BMI unknown.
