You are not being a bother at all! That's what we're here for, and you're not an idiot for asking! How can you ever learn if you don't know?
Did you check out the infographic I linked? It's really helpful and provides a great, pictorial reference for how much to eat and when.
Please don't feel like an idiot. When I started this, I had NO idea what I was doing... I thought it was healthier to eat two sausage and biscuits instead of a sausage biscuit and hashbrowns, because the hashbrowns are deep fried. And I was eating half a day's calories at breakfast alone!
It IS overwhelming, but the good thing is... this isn't all-or-nothing. Make baby steps. Small, sustainable changes that gradually adapt your lifestyle to a more healthy one. You don't have to eat like a rich California vegan to be healthy... you start by working with what you have.
If you're not tracking, start. That's where you start learning. Track the things you normally eat, and start making very small changes. You know what my first change was? measuring my pasta. I didn't stop eating it... I started eating less! Then, I started adding more veggies.
The government food plate is exactly the place you want to start: www.choosemyplate.gov
it's a simple, easy-to-understand representation of where to start. My kindergartener understands it. :) Don't sell yourself short. You CAN do this, I promise! Just start out small, and remember, there's no need for perfection.
