Hi and welcome to 3FC, from one calorie counter to another.
Yes, tracking those calories once and for all can be quite the eye-opener indeed. It's amazing how those things add up and it's even more amazing how certain foods just seem to be loaded beyond beleif with them.
Now that you (we) know, you can work on improving those numbers. Knowledge is power afterall.
Good luck to you. I look forward to watching you progress on your journey.
