Ha, well, you don't "use stored fat to grow a baby." Glucose (sugar in your blood) is the only 'fuel' a baby can use anyway.
Fat really is just stored energy... like a gasoline can you carry around with you. When fat is broken down, one pound of fat equals 3,500 calories. & a calorie is nothing more than a unit of energy. So your body breaks down the fat, metabolizes it, and turns it into fuel you & baby both can use (glucose - actually ATP in the cells itself.)
I've never heard of anything negative coming from the metabolizing of fat stores like that. Maybe someone who's a registered dietician or biologist or something could expand on this - I'm a fitness instructor, & studying for my certs & own personal interest is where my above knowledge comes from (My Bachelor's degree is in marketing - so I have little university education on this stuff.)
All of that aside, my MW doesn't weigh her clients. She has a scale in the bathroom, but says, "You can weigh yourself if you want, either way is fine." I even felt guilty for having gained more than I thought I "should." (I'd gained like 18# at 20W - and I only gained 20# the whole time with my DS! I felt guilty because I HAD been eating more junk food & exercising less than I should have.) I told her the # & she said, "Well, do you not want me to write it down?" Ha! I said, "Nah, might as well put it in the file."
She said in The Netherlands they've stopped weighing PG women. I have serious doubts that paying attention to weight gain at all is an evidence-based practice...
ETA - thought I'd Google to see what comes up based on my last sentence.
The "Guide to effective care in pregnancy & childbirth" doesn't seem to state anything one way or another on monitoring weight or imposing guidelines. (Not that I found)
"pregnancy weight gain evidence"
I found this http://brainblogger.com/2010/10/28/maternal-weight-gain-puts-child-at-risk/
"The authors of the study, published in the The Lancet, analyzed the weight gain of more than 500,000 mothers in the United States who gave birth to more than 1.1 million infants over a period of 14 years. The authors reported that excessive weight gain during pregnancy increases not only the infant’s birth weight, but also the child’s risk of obesity later in life. Since the study analyzed multiple pregnancies of the same mothers, genetic factors were ruled out as confounders of the results."
Ah, OK, so it does make some sense to pay attention to it.
& it's been studied here:
