Hello, Welcome. We started at the same weight almost. I was 1lb higher. I have lost 35lbs since January.
I calorie count. I use an app called my fitness pal because it was free. You can also look it up on time. I would ask to meet with a dietician as they may want you to stick to a certain amount of carbohydrates.
I would also try to start walking 30 minutes a day at least 5 days a week. If it is too much start slower and add 5 minutes a day. To get weight loss going you really need to move 45 minutes or more but you will need to work up to it.
The nice thing about calorie counting is you can have any food you just need to learn portion control.
