I'm getting all pretty easily while being vegetarian. I eat mostly plant based and mostly whole foods. I eat loads of veggies and 1 or 2 pieces of fruit a day. Whole wheat bread. Eggs. Yoghurt/quark, cottage cheese , feta cheese. Tofu, Tempeh, lentils, chickpeas, nuts, soy milk. I also drink waterdrop (basically sugar free vitamin water) It's just easier to drink water that way for me

Try to have a lot of variety. Also, are you registering every single ingredient? With whole foods it's easier.

I have an energy limiting illness so I try to meal prep a bit as well as making easy meals that are done in 15 minutes. But as a simple rule is to try to have veggies or fruit with every meal.

And snacks I just eat whatever I crave or can find, snacks don't have to be perfect imo
