Trying to conceive

I went to a fertility specialist and he told me to lose weight because it would be tough to carry twins with my weight... that's pretty much it. I'm not sure it really has a big impact on fertility otherwise.

I was put on vitamins, baby aspirin, and something else I forgot about though.. so just make sure to eat a balanced diet I guess.

my understanding (not a doc and not super well versed in this) was to try to lose weight prior to TTC to be at a healthy(ier) body weight when TTC. But durring TTC to eat maintenance.

I have heard a bit about being overweight making it harder to conceive. (please no one take the following statement offensively, just a scientific observation) There has been alot of research in livestock that supports being overweight lessens conception rates. That doesn't necessarily translate to humans, but it could. There is also the fact that there may he a higher prevalence of underlying conception issues in the overweight population (PCOS, hormonal issues, thyroid issues) so is being obese the problem, or do people who would have conception issues anyways tend to be obese?

However, from what I have heard dieting while TTC can also cause problems as the body may not want to add extra stress when it is already under stress (weight loss).

However; if you want a useless anecdotal evidence story: I was at about a 1lb/week loss calorie goal when I got pregnant. Keep in mind, for me that was about 1700 cals/day. So we aren't exactly talking extreme restriction. And still at a BMI 30+, so not exactly healthy weight.

Anyways, sorry I don't have any super concrete information to add, but thought it was in interesting topic. Good luck to you!

March of Dimes:

If you’re overweight or obese during pregnancy, you’re more likely to have these complications:
• High blood pressure, preeclampsia and blood clotting problems. High blood pressure is when the force of blood against the walls of the blood vessels is too high. Preeclampsia is a condition that can happen after the 20th week of pregnancy or right after pregnancy. It’s when a pregnant woman has high blood pressure and signs that some of her organs, like her kidneys and liver, may not be working properly. Clotting problems are when blood clots partly or completely block the flow of blood in a blood vessel.
• Gestational diabetes. This is a kind of diabetes that some women get during pregnancy. Diabetes is when your body has too much sugar (called glucose) in the blood.
• Being pregnant past your due date and problems during labor and birth, including problems with anesthesia (pain medicine). You also may need to stay in the hospital longer after having your baby than women at a healthier weight.
• Cesarean birth (also called c-section). This is surgery in which your baby is born through a cut that your doctor makes in your belly and uterus (womb). If you’re obese, you’re more likely to have complications from a c-section, like an infection or losing too much blood.
• Miscarriage or stillbirth. Miscarriage is when a baby dies in the womb before 20 weeks of pregnancy. Stillbirth is when a baby dies in the womb after 20 weeks of pregnancy.
• Trouble losing your pregnancy weight after giving birth
  
  
  If you’re obese, you’re more likely to have other complications, including:
  
• Infections during pregnancy, like urinary tract infections
• A sleep disorder called obstructive sleep apnea. This is when your breathing stops while you’re sleeping.
• A dangerous blood clot problem called venous thromboembolism (also called VTE). This is when a blood clot breaks off and travels through your blood to organs like the brain, lungs or heart. This can cause a stroke or heart attack.
• Needing to go to the hospital earlier in labor, having longer labor and needing to have your labor induced. Inducing labor is when your provider gives you medicine or breaks your water (amniotic sac or bag of waters) to make your labor begin.
• Problems with breastfeeding
