Welcome to the family and Congratulations on taking the first steps of your journey. Everything is a learning experience when you are first starting out and you will find TONS of imformation and support here to help you along the way.
As for your first day meal journal I would recommend adding more vegetables. I make a very large salad (lettuce, tomatoes, bell peppers, cucumbers, red onions, broccoli, radishes, and califlower) and take it to work with me everyday. I have my snacks and lunch from the salad. It is very filling and since I have given up dressing there are literally no calories.
Drink lots of water, green tea and take a multi vitamin everyday is my second suggestion
You can do this we will be here to love and support you every step of the way!
