This statement confuses me a little. If concerned hitting your minimums on protein, and carbs, and trying to avoid being more than 500 calories in a deficit, skipping the meal gets you farther away from all 3 of those goals than just eating a smaller serving of the safest choice they have there.
Did you replace the meal after with another meal, or protein shake, and carbs or something?
I am not saying skipping was an issue by any means and if it was between messing up, completely overshooting calories, and skipping the meal then skipping was probably the way to go considering your goal of weight loss. I just didn't understand the logic at play with that explanation. Either way, you are stringing together wins in my book, so just keep doing what you do Sir!
