Hi and welcome. There is so much good advice on here it will take you some time to get through it. The hardest thing I had to accept was that I had to cut carbs, I mean really, drastically cut out carbs, white, brown whatever colour, they had to go! But I am now enjoying my new diet, and the new me. I am an unheard of 8stone 8lbs, me!, really!
You can substitute cauliflower rice for rice, we had it last night with chilli, I actually prefer it now. And Burgen or low carb bread, I only have a one slice of bread for a sandwich now. I love my breakfasts these days, eggs, bacon with tomatoes, or a tablespoon of low sugar baked beans. And I always eat full fat food to make sure I am never hungry.
There are lots of ideas on here, take time to read through all the other members experiences and diets. I would recommend reading
@Vince_UK's menus on the what did you eat thread, he has had fantastic success.
Good luck!
