According to the Mayo Clinic, far more women gain too much weight rather than too little during pregnancy.
While eating for two is not recommended, dieting for two is far scarier.
Mental health experts say a condition known as "pregorexia" is an epidemic that isn't discussed nearly enough.
Similar to anorexia and bulimia, pregorexia is an eating disorder which many pregnant moms desperately try to disguise.
Kathleen Fetter is a primary clinician at The Renfrew Center, a residential eating disorder facility with locations across the country.
Many of Fetter's patients want their baby to be healthy, but they also want to maintain a thin physique even during the pregnancy.
Doctors worry a woman with pregorexia may give birth to a baby with a low birth weight, vitamin deficiencies, growth retardation, and other long-term health problems.
"At no time in an American woman's life have they ever been told, ‘Hey, gain weight,'" says Dr. Mark Bland, a board-certified OBGYN with Presbyterian Healthcare in Charlotte, N.C.
The condition is commonly blamed on the pictures of petite baby bumps glamorized on today's glossy magazine covers.
Fetter says most of the moms with pregorexia have pre-existing eating disorders which are magnified by the metamorphosis of motherhood.
When some of Fetter's patients at her out-patient clinic give their eating disorder a face, it's akin to a monster who causes pain in their stomach, which is the same place they feel the baby kick.
"Psychologically, what's going on for them is an obsession with their body and a huge fear of change," Fetter says.
Unable to control their widening waistlines, the urge intensifies to cut calories and continue heavy exercise in hopes of fighting off any extra fat.
America Now met up with Laurel Kaufman as she hurled around a Kettlebell and her six-month pregnant belly, leaving us to wonder where pregnant women like her need to draw the line.
"I think there's a lot of pressure on women to look and act a certain way and have it all together," Kaufman says.
Many OBGYNs say fit mothers like Kaufman who have been pumping iron and cranking out the cardio for years only need to modify during motherhood, because daily exercise is essential.
Bland says a simple 'talk test' will let you know if you're pushing your exercise to the extreme. If you can't talk during your exercise regime, you may need to do a less strenuous workout.
When it comes to pregorexics, the calorie-burning effort is extreme and often hidden.
To these women, the recommended 25 to 35 pounds of weight gain during a pregnancy as well as the additional 300 calories per day is terrifying.
What most pregorexic mothers don't realize is that fighting this also causes serious consequences for the developing child.
"The baby kind of takes what it needs," says Bland. "And [the mother] is left with the leftovers."
Malnutrition can leave a woman with brittle bones, or unable to lactate and feed her baby.
A pregorexic's fat-fearing behaviors can be heartbreaking for their families, as the only help they can offer is support.
Clinical care and counseling can help a pregorexic manage and make health changes, but trying to cure or control a life-long complex in one trimester will only leave everyone emotionally exhausted.
Kaufman says a pregnant woman's desire to remain trim is "sort of like their best friend and their worst enemy."
For women dealing with an eating disorder during pregnancy, early identification and professional care can help both mom and baby start a happy, healthy new life.
But for both, it's going to take baby steps.
Doctors tell us that old rumors about keeping your heart rate below 140 beats-per-minute during exercise need to be laid to rest.
Fit moms can continue their exercise, but just be sure to remember the 'talk test.'
And after a baby is born, stay away from those pictures of celebrities who immediately seem to bounce back to their slim bodies overnight!
OBGYNs say the body takes at least six weeks to get back to its base level, so don't worry about fitting into your skinny jeans until well after then.
