I was never a “salad person”. Now there are several salads that I enjoy. I would never touch beans, now I recently found I can sub them for rice in some dishes and still enjoy it.
This is something that happened over years of trying to eat better. There are little things you may find hit more quickly but the macro stuff just takes time.
For example, cutting out soda completely for a month. Not even diet soda. Just find something else to drink, ideally which isn’t fizzy. It’s a relatively small ask as far as “diets” go. After a month or two, you may go back to taste a soda and wonder how the heck you ever liked it.
There are diets which focus on deprivation. And if you actively trying to cut fat then you will need to be in a deficit and you will feel hungry.
But there is also the long term “diet” of just trying to eat better and the good news is that the more you eat healthier foods (e.g. lower sugar) the more your palate will adapt and you will eventually find the sweeter things too sweet and the less sweet things more pleasing. Which makes the whole thing much more sustainable.
I only ask as I bought a sodastream machine after realising what I liked most about soda was the fizz - I actively disliked the sweetness. Now I drink around 3 litres of fizzed water a day and haven't looked back.
1) I'm just paranoid what that could be doing to your gut bacteria,
2) It's keeping your taste buds acclimated to that hardcore sweet flavor (sucrose), which is something you have to train yourself off of, in my experience, to increase your sensitivity to the natural sweet which comes in the healthier options.
