Overconfidence bites me in the behind

I ate something bad today, but I can't figure out what it was.  I know I had something bad, because it's 8pm and I am starving.  For the past few days, I've been very satisfied with my small meals but for some reason I am having wicked cravings right now.

I hope that by documenting this I can figure it all out:

Breakfast:  2 eggs (with cheese and veggies) and 2 strips of center cut bacon.  No problems there, I was full until lunch.

Lunch:  A handful of shrimp and stir-fry veggies.  I found leftover shrimp in the fridge (they were cooked in butter).  I coated the pan with Pam and used 5 spice powder and a bit of soy sauce.

After lunch I was still hungry.  I thought it was because I didn't have enough protein at lunch (the shrimp were tiny). 

3 PM Snack: 1 stick of celery and a small scoop of hummus

That held me for a bit, but by 5 pm I was still hungry.  I went straight for the meat.

Dinner: Some Ribs with BBQ Sauce.  It was sauce from Central Market (HEB is the bomb.com) and I could taste the sugar in it. 

I had protein so why am I starving and daydreaming about the goldfish crackers in the pantry when every other day has been pretty easy?

Just checked-the sauce had 7 grams of carbs.  Was that it?  Was it the soy sauce?  No more stir-fry until I figure this out.  Tomm. I am having the bacon/eggs again and making chicken fajitas. Wish me luck.
