Why lose weight before pregnancy?

Numerous studies have demonstrated the influence of weight on fertility. Indeed, being overweight can affect the ability to conceive a baby naturally. Being overweight is often associated with hormonal imbalance in the body, which can affect your ability to ovulate regularly, and therefore achieve pregnancy.

Weight loss, with dietary support from a health professional and a tailor-made diet, is the first option offered to overweight women who wish to become pregnant.


Overweight and fertility

Being overweight has been shown to reduce fertility. In the case of overweight, weight loss brings a major benefit, especially if it takes place before conception rather than during. It helps to improve pregnancy rates and reduce the use of IVF.


The benefits of weight loss before pregnancy

In particular, gradual and reasonable weight loss before pregnancy can improve:

  • fertility (better oocyte quality, normalization of cycles, reduction of the risk of miscarriage, and improvement of embryo implantation);
  • the course of pregnancy (reduction of the risk of gestational diabetes);
  • the health of the baby and the health of the mother-to-be.



In case of overweight, weight loss is also the first advice given by doctors in the case of polycystic ovary syndrome (PCOS). Polycystic ovary syndrome is a very common endocrine disorder that affects one in five (20%) women of childbearing age. Ovulation disorder is one of the main symptoms of polycystic ovary syndrome. 50% of women with PCOS have primary infertility, and 25% have secondary infertility. In women with PCOS, there is often a scarcity or even absence of ovulation. Their cycles are generally irregular and longer, between 35 to 40 days.

The female cycle is punctuated by 3 phases: the follicular phase, ovulation and the luteal phase. At each cycle, about a hundred follicles begin their growth, thus evolving from the stage of primordial follicles to that of tertiary follicles. Among these hundred follicles, only one, called "dominant follicle", will continue to mature and reach the stage of pre-ovulatory mature follicle. In women with PCOS, follicular maturation is blocked by excess androgens (male hormones). Immature follicles accumulate and grow, without expelling their oocytes.

Several studies tend to demonstrate the involvement of a balanced diet and weight loss in improving PCOS symptoms. Healthy eating and regular physical activity can promote weight loss, encourage the resumption of menstrual cycles and ovulation, and improve your chances of getting pregnant spontaneously. A diet rich in organic fruits and vegetables but also in whole grains and low in fat, cholesterol and sodium can greatly reduce markers of insulin resistance as well as body mass index.\



Monitoring your weight before getting pregnant helps prepare the body for pregnancy and maintain good health before delivery and the arrival of the baby.

The ideal weight before a pregnancy can be provided by the BMI. The BMI, or body mass index, is an indicator that classifies a person's corpulence according to height and weight. A BMI above or below the average can have consequences on health and fertility, but also on the course of pregnancy if you manage to get pregnant. Losing weight before pregnancy limits the possibility of having a high-risk pregnancy and reduces the risk of early miscarriage or complications during pregnancy and childbirth.

BMI is calculated by dividing weight in kilograms by height squared. If your BMI is between 18.5 and 25, you are average. Above 25 we speak of overweight, and above 30 we speak of obesity.

The quality of maternal nutrition before and during pregnancy also plays a major role in the realization of a baby project. The practice of regular physical activity also helps to lose pounds and reach the ideal weight before pregnancy. Sport promotes a better state of mind and contributes to stress management.

Weight loss during pregnancy

During the first trimester of pregnancy, some women may lose weight. At the start of pregnancy, several factors can influence weight loss. Nausea and vomiting can make eating difficult and lower the number of daily calories taken into the body. Weight loss during pregnancy occurs mainly during the first months of pregnancy.

Weight gain during pregnancy

It is generally from the second trimester of pregnancy that the pregnant woman sees her weight gain increase. Different changes take place on the body and influence the weight gain of the pregnant woman: the weight of the baby and the amniotic fluid, the weight of the uterus which can weigh more than a kilo, or the weight of the placenta. The average weight gain during pregnancy is around 11 to 16 kilos. It is generally greater if twins are expected.


When a couple wishes to conceive, it is increasingly advisable to adopt a pro-fertility diet and to practice a sport more regularly. The periconceptional period is the ideal time to adopt better eating habits and to follow a pro-fertility diet. Adopting a pro-fertility diet can improve the fertility of women who wish to conceive a baby. The pro fertility diet increases the chances of obtaining a pregnancy or a birth by combining the nutritional intake of food with supplementation through food supplements.

Dietary management by a professional is an essential element in the prevention and treatment of infertility. This treatment allows you to lose a few pounds and to have the ideal weight for the start of pregnancy. Consulting a nutrition professional also makes it possible to consume calories that are not "empty calories" or "hollow calories", to avoid any deficiencies before pregnancy and to obtain tailor-made nutritional advice in the management. couple infertility.
