Is It Ever OK to Gain 100 Pounds in Pregnancy?

Blac Chyna thinks she'll "snap back," but that's a dangerous game.

Remember a few weeks ago when Blac Chyna got real about her pregnancy weight gain on Snapchat by hopping on a digital scale that returned a readout of 163.2 pounds?

Well, now the expectant mama is at it again, snapping away during yet another weigh-in. And this time, the 28-year-old fiancee of Rob Kardashian lets us in on her starting weight: "Before I got pregnant, I was about 139," Chyna, who's likely in her second trimester, says before hitting the scale. Then when the numbers lands at 165.6 (that's 26 pounds so far, in case you don't feel like doing the math) she lets out a little scream and hops off.

I can't say that I blame her. I was the same way during my second pregnancy. In fact, towards the end, I even started getting on the scale backwards so I wouldn't have to see that quickly-escalating number!

I know, I know. Kinda lame. But my thinking was this: If I didn't know exactly how many lbs. I'd gained, I could just kick back and enjoy my pregnancy (and my McDonald's French fries!), and not worry about losing weight until after the baby was born.


Seems like Chyna may be taking the same approach. Because in yet another Snapchat video, she jokes around about her weight gain while chomping away on chips: "Like, no lie, my goal is to gain 100 lbs. this pregnancy," she says. "I'mma tear it up, and then I'mma snap back."

And I'm just glad she doesn't seem to be stressing the scale too much—though I do hope she's exaggerating a little about the whole "gaining 100 pounds" thing. After all, the average weight gain during pregnancy recommended by doctors is 25 to 35 pounds, and Chyna has already entered that range.

Keep in mind, however, that according to Dr. Heather Rupe, OB/GYN and medical editor at WebMD, the ideal amount of weight you should gain while preggers depends on your pre-pregnancy BMI.

So, if you’re a normal-weight woman (BMI 19-25) to start with, the recommended weight gain is, in fact, 25 to 35 pounds. But that number moves down to 15 to 25, Dr. Rupe says, for an expectant mama who started off overweight (BMI 25-30).

It decreases even further for obese women, dropping to 11 to 20 pounds. And for all those mamas who started off underweight (BMI <19), Dr. Rupe says the average amount of recommended weight gain moves up to 28 to 40 pounds.

Of course, every pregnancy is different and those numbers may fluctuate a little. But according to Dr. Rupe, gaining 100 pounds is never OK.

“Excess weight gain increases the risk of multiple complications during pregnancy including C-section, gestational diabetes and shoulder dystocia,” she explained to us. “It’s also been linked to long-term obesity—those of us who have been there knows it's really HARD to lose that baby weight.”

To avoid extra weight gain, keep this in mind: "I tell my patients that in pregnancy you are not really eating for two literally," Noel Strong, MD, Assistant Professor of Obstetrics, Gynecology and Reproductive Science at the Icahn School of Medicine at Mount Sinai tells Fit Pregnancy. "The common myth that you need to eat twice as many calories to support your growing baby is untrue. The average woman really only needs to consume about 300 extra calories a day to accomplish this goal, which equates to approximately 0.5kg weight gain per week. This is more like adding two healthy snacks a day to your diet, rather than double helpings at each meal."

But if, like Chyna, you suddenly find that you've packed on a little too much pregnancy weight, don't panic. Plan a time to sit down with your doctor to talk about getting back on track.

And in the meantime, you know the drill: Try to stay active (hello, prenatal yoga!), 86 the empty calories (bye-bye, fries!) and reach for foods like veggies and fruits that are big on bulk and low on calories.

“I tell my patients that they are pregnant, so they are going to have cravings,” Dr. Rupe explains. “But give into those cravings twice a week—not twice a day.”
