I wouldn't use the creamers. Instead, get a rtd shake at your clinic today or a vanilla pudding. Use it as the creamer. Using sugarfree chemicals is not helping you and is adding unnecessary oil and fat. If you were going to add back fat wouldn't you prefer it to be some extra olive oil for cooking?
Use skim milk instead of 1/2 and 1/2. 1/2 and 1/2 has both fat and carbs at levels more than skim.
So, you spent week one learning. I did the same thing. I ate root veggies multiple times in the week and had tomatoes each day. I still lost 9 pounds. (granted I was still 50 pounds heavier than you are now!) I am just saying, you will have lost something. And, next week will be better.
