I hate egg which people enjoy winding me up about. And avacados.
Apart from that, I’m pretty open to most things - adore strong, and often spicy flavours.
Except the time when I was on meds, and also when I had mono for 6 months - all I wanted to eat was Mac and cheese, pizza and ice cream.
For me I get into habits. When I’m on a healthy run, it’s really soul destroying for about a week but then suddenly becomes fairly easy to maintain. Think this is true for lots of people, so worth baring in mind when you struggle with a diet change.
Have a major major weakness for takeaways which will always be with me though.
