Yes, this. I'm not really familiar with chronometer but have used an app that sounds similar. I agree with the poster above too, that eating less and moving more. It's not bad to try to be the healthiest for you. Anecdotal, but I didn't pay for any diet service and just started paying attention to what I was eating, and moving more. Even on days when I wasn't feeling great or so tired. It's paid off so far, and I feel better.It won't be long (and I'm not wishing this on her BTW but I've seen firsthand what food choices can do long term) before she becomes seriously unwell.
Trust me.. This stuff catches up with you. You can't go stuffing your face with the things she chooses and not have some minor ailments... These are warning signs from your insides to stop treating your body like tit before things really get fucked up.
She should really try the chronometer app to see how well her choices are treating her (and I mean to track actual foods - not supplements for everything) as I eat relatively healthy and even I was shocked at how low in some vits and mins I was.
Most people like a treat sometimes more often than we should but ffs gabby you are doing yourself no favours and Mark my words all this crap will come back to bite you.
Also OT sort of side note question, here in the US where I am, if you had someone stay with you that long even if they weren't on a lease, they'd still be considered a tenant. So say you got sick of eachother and wanted to kick the other person out, you'd have to go to court to legally get them out. Is it the same or similar in UK?
