I use
www.thedailyplate.com and try and keep around 1,500 cals (that is what is recommended for my height and weight by thedailyplate.com) but I also make sure I don't go above 100% of any of my RDA of things like sodium and carbs, etc. I wouldn't say I'm on a low carb or smart carb diet, but I DO try and only eat brown rice instead of white, and wheat pasta instead of white and sweet potato instead of white, etc, things like that. but it's not ALWAYS possible.
