Welcome @Sarahg To the low carbers tent.
Veggies are not only good but great source for your carbs to come from, I don't eat much bread at all have stopped all breakfast cereals completely, making my feed days 16:8, I've reduced my intake of rice, pasta, cakes and biscuits, also as I said above now eating very few potatoes, and gave up sugar
3 months ago, on the subject of nuts I now don't buy them coz I would eat the lot!!
I know they're a source of good fats but I've still got a lot of weight to lose and for me that's a step to soon.
I'm thinking sweet potatoes are bit high in carbs but not sure so you'll need to check that one out.
Just try a few adjustments and see how you go on, carbs make us retain water which adds to weight gain and water retention is my biggest problem that's my main reason to low carbing/health.
