Calories vs Sodium vs Sugar

I do not track sugar or sodium and it has not affected my weight loss. It is more important to keep an eye on your protein, fat and fiber targets. Give this a read if you haven't yet. It's full of great information:

I had to break my "addiction" to salt because I did go through a crazy amount of it. My mother could put salt on salt when making dinner, and I would eat salt like candy.

There are a number of health issues associated with to much salt, blood pressure, kidney disorders, water retention and osteoporosis.

If your really worried about salt then there are low salt alternatives to canned soups (although not living in the same country I can't really point you anywhere other then google).

So after a couple weeks, I'm now seeing a pattern with my food. I usually come in under my calorie limit (yay!), but either my sodium, my sugar, or both are over their limits (boo). It's not that I put salt on everything - hubby broke me of that habit years ago. It's more a matter of the fact that my lunches at work tend to be Campbell's soup or Rice-a-Roni or whatever.

So while I know that I really SHOULD strive for getting all three under their limits, is one more important than the others?

Unless you have medical reasons for restricting sugar or salt, you don't have to worry about it. Just make sure you're hitting your macros and are reasonably around your calories goals and your weight loss will be healthy.

I struggle with HP so I avoid prepackage and processed foods. They are some "better" choices on the shelves, you just have to read the nutrition labels. I have found lower sodium choices at the supermarket in the natural foods isle if available.
