Pregnancy Weight Gain Tracker. What should my weight gain during pregnancy?


Gaining weight when you are pregnant is perfectly natural, it is even recommended for the health of your baby. But taken too little weight can be harmful to your health as that of your child, take too much are also risky. So what should be your goal and what to expect from your balance? No panic, you can use a pregnancy weight gain tracker to accurately calculate your weight.


There are two commonly used methods to calculate what should be your weight gain during pregnancy:

  1. BMI
  2. The ideal weight and curves Rosso


1. Calculate your size and weight of pregnancy with the BMI
The most frequently used nowadays indicator to determine the weight and position of a person from there, estimate the weight you will take during pregnancy, is the BMI or body mass index.Pregnant woman taking weight
BMI calculates the corpulence of a person by the person’s weight ratio of its height squared (P / T ²).


2. Calculate your size and weight of pregnancy using Rosso curves

Another indicator commonly used in many nutrition studies is the formula of Lorentz associated with Rosso curves. This method has the advantage of being much more accurate than the previous one. It also provides better visibility on the distribution of decision throughout pregnancy weight (which is not the case of BMI, which gives just an end goal). You are thus able to check your weight curve, week after week.

Start to calculate your ideal weight before pregnancy. To find out, use a pregnancy weight gain tracker then, using the Rosso curves to calculate the theoretical weight gain depending on your starting weight and ideal weight before pregnancy.


In practice, we must remember that in late pregnancy weight should be a maximum of 120% of ideal weight before pregnancy for all women whose starting weight is between 70 and 105% of their ideal weight. A future mom overweight in early pregnancy should theoretically gain less weight than a mom-normal or lean build. To calculate taking foreseeable weight during your pregnancy, use a pregnancy weight gain tracker!

How is weight gain distributed over the 9 months of pregnancy?

During the first trimester of pregnancy, weight gain is usually very low or almost zero. Indeed, nausea during the first 12 weeks are (unfortunately) the most effective appetite moderators.


It is during the second trimester that the biggest weight gain will occur. Considering that approximately 60% of the total weight will be earned during this period. Weight gain generally slows during the third trimester to get to average 1 kilo per month for a normal weight woman. It is in principle approximately 40% of the total weight acquired over the entire pregnancy.


Should we really eat for two?

No question of diet during pregnancy! But can we, therefore, get away with anything? The ideal is, of course, balanced eating. Prefer a healthy diet, limiting sugar and fatty foods.

But where pass all those kilos?

You magnify, but to what benefit is this weight for? In fact, only a small part of the weight gained during pregnancy will join your reservations. The rest is only temporary and will quickly disappear.


Here’s how this weight comes in you.

  • Fetus: 3-4 kg
  • Placenta: 700 g
  • Amniotic fluid: 900 g
  • Increased blood volume: 1-1.5 l
  • Breasts: 400-500 g
  • Water Retention: 2 l
  • Fat reserve: 2-3 kg


A total of 10.2 to 12.8 kg on average, for a person of normal weight.

And after childbirth? How do you lose your weight?

If you have gained weight reasonably during pregnancy, that is to say, in line with the recommendations given above, the accumulated fat reserves should not be too hard to lose. As for the often accumulated water retention, it will evaporate very quickly after birth (sometimes overnight sweats).


Conventional wisdom often said it took nine months for your body to give birth to your baby, and it will also have nine months to return to its original shape. Do not yield to the temptation to force your body to get into your favorite fit jeans a few weeks after delivery, especially if you are breastfeeding. Be patient and let nature take its course!
