Experiencing a change in your tastebuds &/or sense of smell (the smell of certain foods turns your tummy) is usually temporary. When I first started eating vegetables again my old favourites tasted disgusting but after a few weeks I could eat them without issue. Any prolonged change in your tastebuds usually occurs because you have reduced or removed certain foods/flavours from your diet & when you have them you don’t enjoy them as much. I still find some foods really sweet but that’s because I cut a lot of sugar & sweeteners out of my diet so it’s a good thing for me.
Generally the first couple of months can be challenging & cause a bit of an emotional roller coaster as you’re trying to sort out your eating choices, routines, etc. it does get easier. Because we eat such small quantities to begin it can make us weak, tired, or just blah if we miss meals & don’t hit our fluid & protein goals. You’ll work out ways to compensate for busy days that throw your routine too. I always took an electrolyte drink with me when I was going to be busy for an energy boost or you could take a protein shake. Zip lock bags with foods you can tolerate can be helpful too like nuts or jerky as you’re allowed. For a while after goal I kept a protein bar in my bag. Maybe keep a small insulated bag in your car with some cheese, deli meat, etc. I also made sure I took a break - sat & had a cup of tea for 20-30mins.
It’s just all new, different, strange, … . Before you know it, you’ll be out & about, socialising, dining, getting on with life & you’ll look back & think that time I struggled was only for a short time really & now life is great.
All the best.
