You are doing very well!
These are the worst days, the most likely ones to want to give up - so congrats on keeping up!
You mention calories. I don't know much about that. But your meals might be a bit light on proteins perhaps?
I'm assuming salad smoothies are only veggies, and I'm not sure that bubbles & squeak dish (amusing name btw) have enough proteins either.
Remember to have 1-2 palm-sized portions of proteins in your meals and don't forget about fats either!
Also smoothies are not a great meal choices.
Drinking your meals is not the same as eating them, so whenever possible choose eating your veggies without blending them.
But, most important of all: Keep it up!
