A significant increase in blood volume, amniotic fluid, and a growing baby add to the mother’s total body weight. Women who are already overweight or suffering from obesity will eventually gain some weight during pregnancy. However, they can lose problematic body fat and get rid of weight-related complications via safe applied methods & naturally during pregnancy. They become nauseous or have food aversions and unintentionally start losing weight during pregnancy (especially at the early stages). Regardless, one should always share all the symptoms with the doctor or health care provider.

Opting for extreme diets during pregnancy to lose weight is not advisable. You should eat enough to provide the baby and yourself with sufficient nutrients. It is essential for your overall health. At the time of pregnancy, going on diets, cutting calories or restricting food groups can impact the development of the foetus and deprive the body of required nutrients. It is essential to learn the risk associated with being overweight and the risk involved in losing that weight through unsolicited methods.

Risks of Being Overweight During Pregnancy

Obesity during pregnancy links to poor health outcomes for both the mother and the child. A study claims that the probability of conception decreases, starting from a BMI of 29 kg/m2. The same study claims that a high body mass index also increases the chances of various other risks like:

  • High BP or blood pressure
  • A severe form of gestational blood pressure or preeclampsia
  • Gestational diabetes
  • Intrauterine death
  • Obstructive sleep apnea is a condition where you stop breathing for short periods during sleep.

Obstetricians watch blood pressure and blood sugar levels during pregnancy and lookout for signs of high blood pressure or gestational diabetes. Such women are given specific diets or exercise advice to mitigate such conditions to promote a healthy pregnancy & delivery. 

Can you Safely Lose Weight when Pregnant?

Medical experts usually encourage women to eat enough nutrients and exercise daily to keep their babies healthy. In addition, most healthcare experts do not recommend pregnant women to follow a weight loss diet as it can increase complications for the baby. However, with more research and advancements, some healthcare experts believe that there are safe measures that one can take during pregnancy to lose or manage healthy body weight. Ideally, women should try to ward off the extra kilos before becoming pregnant to avoid unnecessary risks to their health and babies.

If the woman does not gain any weight during the pregnancy, she will start losing the fat stored. As a result, her body weight might reduce than before the pregnancy. If a woman loses weight during her first trimester of pregnancy, it is due to nausea or morning sickness. Severe morning sickness can also deprive the body of nutrients, and being on call with a doctor during the entire period is advisable. Weight gain is usually experienced by women during the second trimester when they slowly start to feel better. 

Optimal Weight Gain Recommendations During Pregnancy

Women often meet with an obstetrician or their doctor to develop a care plan when they become pregnant. Your first visit will involve discussions regarding nutrition and physical activity. The weight gain guidelines will follow your starting weight as per your pregnancy. BMI may not be the perfect indicator of health, but according to the Institute of Medicine, there are different weight gain recommendations for women under different weights. Your BMI does not consider body composition, ethnicity, race, gender, or age. It is quite an incomplete measure but an easy method to analyse your potential health status and outcomes. It is pretty quick and hence holds value in the medical community. However, not all doctors follow BMI guidelines but use IMOM recommendations to guide women towards ideal weight goals. 

Considering Weight Pre-Pregnancy

It would help if you considered your weight at the pre-pregnancy stage. Take guidance from the doctor or health care regarding shedding off any extra kilos or gaining an ideal weight to promote fertility & healthy pregnancy. People of all shapes & sizes can get pregnant, but as per studies, prematernal obesity can cause various complications. These complications include the risk of preeclampsia, preteen birth, and macrosomia, where the foetus is larger than the standard size. In addition, it can cause injury during childbirth. Therefore, one should consider positive, sustainable lifestyle changes to support a healthy weight and boost fertility. 

Safe Ways to Manage Weight During Pregnancy

Eat Small Meals

Pregnant women should eat small but continuous meals throughout the day and keep snacking too but healthy. Ginger honey paste or ginger candies are said to ease nausea. 

Avoid Fatty Foods

Morning sickness is a common symptom during pregnancy which increases because of deep-fried, heavy and oily food items. 

Know Your Body Mass Index

If you want to make changes in your diet, you should keep track of your BMI or Body Mass Index. A normal BMI range is between 18.5 to 24.9, and thus it is advisable to not gain more than 10-12 kgs during your entire pregnancy. But if your BMI falls under 18, you should gain around 10-12 kgs. So weight gain should be 7-10 kgs with a BMI range between 25-29.9 and only 5-9 kgs if overweight. 

Don’t Miss Your Dose of Vitamins, Minerals and Calcium

It is essential to consume your vitamins and iron or calcium supplements daily. It is crucial for the optimal growth and development of the baby. Also, please note that you do not combine iron and calcium for best absorption. 

Exercise

If you unintentionally start losing weight during your pregnancy, you may feel weak and feel like staying away from physical activity. In that case, talk to your doctor. Then, once you get the go-ahead, start a gentle form of exercises like walking or prenatal yoga. It would help if you kept at physical activity to eliminate pregnancy woes and abnormal weight gain. 

Be Aware

You should be conscious of what is happening to your body. A gradual weight loss during the first trimester is average, but a sudden loss of 4-5 kilos can be dangerous, and you should immediately reach out to your doctor. 

Cut Down on Calories

Be mindful of the number of calories you consume to keep the extra kilos at bay for your baby to remain healthy. A pregnant woman should consume at least 1700 calories per day. You should keep track so that you do not exceed the count or go below it. Stay hydrated.

It is always a good thing and beneficial for the body to stay hydrated – pregnant or not pregnant. However, if you indulge in physical activity during pregnancy, you need to add a few extra glasses of water. Drinking 1-2 litres of water will keep you full and keep overeating at bay. 

Eat Healthy Snacks and Stay Active

You already know that you should avoid junk food and fill your platter with fresh fruits and vegetables. Go for whole-grain cereals and bread & low-fat dairy products. Spinach, strawberries and beans are rich sources of folates, while high-fibre foods help in better digestion. It also prevents constipation which is a very natural occurrence during pregnancy. 

It is also necessary to stay active and go for at least 30 minutes of mild physical activity on most days of the week. You can discuss it with your doctor to find out that it also has a lot of stress-relieving benefits. Ensure you consult your doctor once as not all kinds of pregnancies can accommodate physical exercise. It might be a problem if you weigh on a heavier scale. If recommended, you can go walking, swimming, cycling, plus low-intensity exercises. Avoid exercising on higher altitudes and let go of any forms of exercise that require you to lay flat on your back – as it affects the blood flow to the foetus.
