For most women, the first few months following childbirth means going through an emotional rollercoaster — it’s humbling, scary, exhausting, blissful, surreal, and relieving all at once.
As you hold your tiny bundle of joy in your arms, you’re probably relieved that the hard part is finally over!
But, if you're like most women, that little bundle took a toll on your body. A post-baby pooch looks back at you in the mirror. Your sore, tender, and cracked nipples from breastfeeding aren't doing anything to encourage you to exercise. Those pre-baby jeans in your dresser? Strangers.
Whether it’s your first or fourth, there’s no denying that pregnancy can make an impact on your body. Even if you were in good shape before pregnancy, putting on additional weight and the appearance of a flabby stomach are almost always inevitable following childbirth.
Should this stop you from thinking about getting pregnant for the first time? Or planning for kid #3? For some, it does. Others don’t really mind. While there's no right or wrong answer, there is good news for those who do become pregnant: you can regain your body composition. The key is knowing what to expect in terms of body composition changes, and what you can do to bounce back from these changes.
Let’s figure this out, shall we?
Body Composition Changes During and After Pregnancy
The changes you experience during pregnancy and childbirth is your body’s way of nurturing your little one for nine months and preparing your body for labor. Body composition changes are no exception.
During pregnancy and following childbirth, the two big, unwanted changes in body composition are fat mass gain and diastasis recti - don’t worry if you don’t know what that second term means, we’ll get into it in a minute.
Increased Fat Mass Gain
Why the sudden need to store up fat? Because it intuitively knows that you’ll need the extra fat for the developing baby during pregnancy and breastfeeding.
But how much body fat? And where? Unfortunately, this is the part where it becomes a bit tricky, with few definitive answers in sight.
In a prospective study that measured subcutaneous body fat changes from pre-pregnancy through 6 weeks after childbirth among 557 healthy women, researchers found that subcutaneous body fat (the fat under your skin) is stored in different places, in different amounts, at different times, varying between women.
Further muddying up any usable insights is the fact that researchers also can’t effectively determine types of changes that happen in a mother’s body composition (her Lean Body Mass, her Fat Free Mass, etc.) due to a variety of factors, not the least of which is the inability to separate the body compositions of the mother and her baby.
However, one of the more reliable predictors of the degree of body fat gain seems to be if it's the first baby or not Research has indicated that first-time mothers had higher body fat gain during pregnancy than moms with multiple children. Six months after delivery, it also turned out that the first-time moms retained more of the excess fat they gained than the moms who already went through previous childbirths.
By the time you give birth, your will lose a huge chunk of the weight you gained— the baby, placenta, extra blood, and fluids will go first. For the next six weeks, the uterus will shrink in size and return to its pre-pregnancy weight.
Unfortunately, the fat stored during pregnancy will not automatically disappear. Your body will likely cling to the extra stores of fat and ready itself for breastfeeding - something that can actually help you lose pregnancy-gained body fat - but more on that in a minute.
Post-Baby Pooch (Diastasis Recti)
One major impact that pregnancy can have on your body is something called abdominal muscle separation, or diastasis recti.This happens when your outermost ab muscles (rectus abdominis) that run from the breastbone to the pubic bone pull apart from the fibrous attachment point (linea alba).
Diastasis recti is a somewhat common occurrence after pregnancy but the degree and location of abdominal separation varies from one woman to another. In a study of both first-time mothers and women who have gone through multiple births after vaginal delivery, the researchers found out that when relevant diastasis recti occurred, 68 percent of the women had diastasis recti above the navel, while 32 percent of the women had separation below the navel.
As your pregnancy progresses, your uterus will make room for the growing baby, which in turn causes the abdominal muscles to stretch and appear flabby. Fortunately, diastasis recti isn’t linked with complications for the mother or the baby, nor is it a sign of muscle loss.
The degree of diastasis recti may decline following childbirth, but it almost always won’t disappear completely on its own.
In a nutshell, the weak and unsupported abdominal muscles are what’s behind the noticeable tummy pooch post-pregnancy, or why you can look like a few months pregnant even after giving birth.
Your Action Plan
Now that you have a clearer picture of the two unwanted body composition changes following pregnancy — excess fat storage and loose, weak abdominal muscles —let’s take a look at the possible steps to help restore (and even improve on) your pre-baby body composition.
Impact of Breastfeeding and Body Composition
Breastfeeding and body composition are probably the last things you'd ever link together, but as it turns out, there's a growing body of research showing that there may be a relationship. One of the most striking comes from Denmark, where an epidemiological study suggested that breastfeeding could eliminate reasonable weight gain (defined as 12 kg, or about 26.5 pounds) in six months of breastfeeding.
These findings are further corroborated by the results of an American study comparing body fat loss between exclusively breastfeeding and mixed feeding mothers. The researchers found that exclusively breastfeeding promotes greater body fat loss than mixed feeding among mothers during the first 12 weeks following childbirth.
Considering that you still need fat to produce milk for your little one, how much weight loss is considered “safe” while breastfeeding?
A weight loss of approximately 0.5 kg, or about a pound, per week (between 4 and 14 weeks after childbirth) in overweight women who were exclusively breastfeeding was shown to have no effect on the growth and development of their newborns.
Your Diet, Nutrition, and Physical Activity During and After Pregnancy
From a nutritional standpoint, a high-glycemic diet during pregnancy is more likely to result in excessive weight gain and overweight babies, while intake of low-glycemic carbs is associated with weight gain that’s within the normal range.
If you’re planning to get pregnant or are pregnant now, pay special attention to the quality of your carb intake.
Health care providers will often advise women to avoid drastic diets for the first four to six weeks after delivery. Besides giving your body time to recover, you also need to establish a consistent milk supply (rapid weight loss might interfere with breastfeeding).
Before going on a diet regimen or exercise program, check with your healthcare provider first to rule out any existing medical conditions.
So which is more effective in helping you get rid of the excess fat mass after pregnancy — diet or exercise?
This study revealed that dietary restriction is more effective than physical activity in accomplishing significant weight loss among women who are breastfeeding. However, this should not be an excuse to dismiss exercise altogether.
Remember the post-baby pooch?
You can reduce its appearance by focusing on integrative or compound exercises for the core muscles (abdominals, back, and the muscles around the pelvis) rather than isolation exercises. The former has been shown to be more effective in rebuilding the core. For example, opt for side planks with arm raises and mountain climbers over sit-ups and crunches.
Exercise after childbirth
In their 2015 guidelines on physical activity for pregnant and post-childbirth women, the American Congress of Obstetricians and Gynecologists (ACOG) recommends the following:
Exercise routines may be resumed gradually after pregnancy as soon as medically safe, depending on the mode of delivery, vaginal or cesarean, and the presence or absence of medical or surgical complications.
Some women are capable of resuming physical activities within days of delivery. In the absence of medical or surgical complications, rapid resumption of these activities has not been found to result in adverse effects. Pelvic floor exercises could be initiated in the immediate postpartum (after delivery) period.
Regular aerobic exercise in lactating women has been shown to improve maternal cardiovascular fitness without affecting milk production, composition, or infant growth. Nursing women should consider feeding their infants before exercising in order to avoid exercise discomfort of engorged breast. Nursing women also should ensure adequate hydration before commencing physical activity.
Be Kinder to Yourself
Keep in mind that it took nine months for you to put the additional weight on, and it may take another nine months (or even longer since you have to take breastfeeding and caring for the newborn into account) for you to regain your pre-baby body composition.
Forget celebrities who quickly get their pre-baby body back. Take note that they have an army of chefs, fitness trainers, and plastic surgeons behind those slender physiques weeks after childbirth.
Nevertheless, before embarking on your post-childbirth body composition makeover, you need to know where you’re currently at. This means getting your body composition tested to help you set body composition goals that’s specific for you.
Ultimately, give yourself time. Changing your body composition, whether you’ve had a baby or not, is a lifestyle, not an end destination - and certainly not one that you need to reach by a certain time. By taking steps now that make the most sense for you and making gradual positive changes, you’ll be back to your pre-baby body before you know it.
