I don't think there is any reason about worrying about amount on the first part of induction. Just eat till you are full and space out your meals. Have a snack if you need to.
I don't know but I would worry abit about Denny's skillet dinner. Is this the restaurant Denny's? Did you look up on their online menu what the carb level is in it.
the same is true for the deli ceasar salad. Do you know what is in it?
Did you count the carbs for the day? How much was it (net carbs)
And my last comment would be snacking on veggies - which is good but it is often good to "level out" the meal by having some protein and/or fat with it. Like a dip of some kind.
Great on the water.
