Weight change and corresponding participant experience		Illustrative quote
Above-average weight loss
	Diet was easier to implement, motivated to eat well	It’s been easy to be honest with ya. You know, I don’t crave bread, I don’t eat bread, I eat a lot more vegetables, very, very little fried food. I mean, it’s been easy . . . And once I walked around with that thing in my arm and I was scannin’ myself every day that just that put a whole new perspective on it. [Participant 169, Interview 1]
	Saw positive changes	I’m sleeping better at night. I have more energy I’m in more control of myself, meaning, you know, it’d be like when I was bored, oh, I’d go to the cupboard or something, and just get a little bit of this or a little bit of that. But now I just feel like I eat 3 to 4 times a day and that’s all I need. [Participant 102, Interview 1]
	Planning or intentionality	So right now I’m kind of finding my… baseline on what my triggers are. I haven’t really been counting carbs, but I did reach out to my doctor, and I started using continuous glucose monitors, to see if it would help me (Um-hm) So, modified, I guess, yes. I… I’m not necessarily counting carbs, but I’m seeing which foods spike my sugar right now. I’ve only had it in for maybe 4 days. [Participant 193, Interview 2]

	Difficulty implementing diet	It’s just that to me a low carb diet is a hard diet . . . and they’re hard to cook. I mean you know, people like me, I’m used to eating pasta, potatoes, you know stuff like that. And those things are easy, quick, you know. [Participant 141, Interview 1] I don’t do really well on low carb. When I go no carb or low carb, I don’t do well. My brain does not do well without [carbs]. I just don’t do well. I get emotional… I was crying, I was having mood swings. [Participant 144, Interview 2]
	Culture of food	[There were] different parties and different things that I had at work that involved eating. Meetings where I had to take people out for lunch when we get a new hire, and a lot of times you can’t really find things that fit specifically into what you’d like [to eat]. [Participant 179, Interview 2]
	Hard to change habits	You have to break your whole habits. I think from what I’ve seen it’s probably a good diet, but it’s definitely not easy . . . I mean, we’re… well I’m 71, my wife’s 71, my daughter’s 45, and we’ve… lived like this for a long time. So to just up and change everything is hard. [Participant 141, Interview 1]
