Stumbled across this web site the other day and it has a ton of free dieting calculators and tools -
Specifically, I like this daily calorie calculator for daily caloric needs.
They also have a calorie calculator for caloric intake for during pregnancy and breastfeeding.
(Not recommending to use this instead of professional advice. I'd still consult with a doctor or lactation consultant, but it's a good tool just to see)
There's some other good resources and information on this site.
Additionally, I found this article on Pinterest from Live Strong, called Losing Inches vs. Losing Weight. It was published last year, but it's a great read.
Off to make my shake for breakfast!
Have a happy Friday and a great weekend!
