Pregnancy Weight Calculator
You’re pregnant, and you’re likely to gain weight. That’s a given. Your baby will grow and will require some extra calories from you to do so healthily. How much weight to gain and how to keep healthy should be areas you focus on as you prepare for your little one to arrive? Here are some ideas on what to expect about weight gain during pregnancy.

How Much?
How much you weighed before you were pregnant and if that’s the right weight for your height determines how much weight you should gain when you’re pregnant. You should gain between 25 and 35 pounds if you were at a healthy pre-pregnancy weight. You’ll want to add one to five pounds to your frame during your first trimester and then a pound a week after that.
If you were underweight before pregnancy, you should gain between 28 and 40 pounds, and if you were overweight, aim for 15 to 25 pounds. If you were obese, you should add between 11 and 20 pounds.
How Can You Stay Healthy?
Control your eating. Being pregnant isn’t an excuse to eat twice as much food. You only need about 340 extra calories each day during the second trimester and 450 extra calories during the third trimester.
Use a pregnancy weight gain calculator to make sure that you are staying on track each week of your pregnancy. Do exercises that your doctor approves to keep your heart and muscles healthy. Pregnancy is not an excuse to sit on the couch for nine months. It’s an excuse to get your body in great shape to help your baby grow strong and to prepare for labor.
What if You Want to Diet?
When you’re pregnant is not the time to start to diet. Your body sugar can drop significantly between meals while you’re pregnant, so be aware that you may feel like you’re extremely hungry and want to eat between meals.
Try to diet on top of that, and you’re going to feel like you’re starving. Your baby will take what he needs from your body to stay healthy, so if you diet, your body is the one that is going to suffer because your baby will be using all your extra nutrients to grow.
Use a pregnancy weight gain calculator to estimate how much weight you should gain during pregnancy and find your target weight range for each week or month of pregnancy.
