How Much Weight Should You Gain When Pregnant With Twins?

Earlier women who expected twins were usually suggested to gain around 35 to 40 pounds of weight without taking into consideration their individual pregnancy size. The Institute of Medicine issued new guidelines that are individualized to pregnancy Body Mass Index (BMI). This way, there is more chance that the twins will be born healthy to a healthy mother.

Your weight gain should be consistent throughout the pregnancy, especially during the first 28 weeks as this reduces the chance of premature delivery. If you are underweight (BMI is less than 18.5, then you should gain 50-62 pounds; if your weight is normal (BMI 18.5 – 24.9), then you should gain 37-54 pounds; if you are overweight (BMI of 25 – 29.9), then you should gain around 31-50 pounds; and if you are obese (BMI is greater than or equal to 30) then you need to gain around 25-42 pounds. Here are some tips for meeting your recommended weight.

  • Consult your doctor about how much weight should you gain for a healthy pregnancy and then work with him throughout your pregnancy to make sure you are on track.
  • Keep track of your weight gain throughout your pregnancy and compare it to what your weight needs to be for the month you are in.
  • Follow a balanced diet. Eat healthy foods that meet the nutritional requirements of you and your babies.
  • Avoid or limit consumption of solid fats and added sugars.
  • Pay attention to your calorie needs. You may not need any extra calories in the first trimester of your pregnancy, but in the second trimester, you will need around 340 additional calories per day and 450 additional calories per day in the third trimester. So, make sure your calorie requirements are met.
  • Get enough exercise and physical activity. You need to make sure you do some form of pregnancy exercises or at least go for a walk every day. Physical activity is considered to be very healthy for pregnant women as long as they do not overdo it at once.

How to Avoid Low Birth Weight Through a Proper Diet

In the case of a twin pregnancy, the chances of the babies being born with a low birth weight increase. Low birth weight is also known as Intrauterine Growth Restriction. To lessen the risk of low birth weight, do not have large meals, instead opt for small and frequent meals every day. What you eat should be healthy. Protein is very important during pregnancy and while you may prefer eating non-veg food, it is recommended that you get some of the protein from non-animal sources. Add more nuts, seeds, beans and vegetables to your diet. Vegetarians and vegans needn’t worry about any kind of protein deficiency for as long as you keep your diet varied, you will be just fine.

When to Consult a Doctor

If you feel excessively tired and find that your immunity level is going down, then it is a sign of nutritional deficiency. In such a case, you should consult a doctor. You can also contact your doctor if you notice you are gaining or losing too much weight. Ideally, you and your doctor should discuss what you should eat and what to avoid, depending on your BMI.


Here are some frequently asked questions about twin pregnancy diet.

1. Should I Eat More When Expecting Twins?

You do not have to eat too much; as long as you maintain a strict and healthy diet you will be okay. Keep your weight in check. Opt for healthy snacks like baby carrots, cherry tomatoes and a hummus dip or a trail mix of different kinds of nuts to which you can add a few dark chocolate chips and dried fruits.

2. If I Struggle to Eat, Will My Baby Get Enough Nutrients?

This can interfere with your appetite, but as long as you stick to the twin pregnancy nutrition guidelines, you will be fine. Do not binge eat and drink plenty of water and fluids between meals and make sure your diet is varied and of the best quality. You will need to consult your doctor and discuss how you can handle this situation.

Compared to a single pregnancy, a twin pregnancy can be a lot more challenging.
