Someone told me once

GET SEXY- GET PREGNANT

Lol like eat better and stay active, vitamins and such make you feel better , and maybe even look better ergo building confidence, which usually turns on your S/O and hell even yourself ( you know when you feelin yourself!!) as well as of course having a healthy BMI promotes over all health.

I thought it was pretty funny She told me , she lost 60 lbs and got these sexy legs and a flat tummy and then got pregnant. After baby she had gained about 40 back and had to work to lose it all again, bam pregnant again. For #2 she didn't gain much so she slimmed down again quickly after.
