Welcome to the beack Katie!!!
You never gave much information so I am assuming you are still in phase 1?? If so, it is entirely normal to feel a little sluggish for the first week. Make sure to eat frequently, your meals and snacks. Eat lots of veggies and adequate protein until you are full to keep your energy up.
First, what don't you like to eat? Maybe that way we can give you suggestions that you would like. Maybe you can check out the recipe forum and see if you can find anything in there that you would like.
Keep at it. You have already lost 10 pounds!! That is great, you seem to be doing the right thing so don't get discouraged. We are here for you
