What’s the ideal weight for IVF?

The ideal weight for IVF is your ideal weight.

A: Sometimes you’re not going to get to your ideal weight because if you are over 100 kilos and you’ve got a lot of weight to lose, then you’re not going to wait to get to your ideal weight before you actually try. However you need to aim for at least a 10 percent weight loss.

If you have a lot of weight to lose – anything from 10 kilos – you will need to lose weight to optimize your fertility. The scientific evidence is very clear about the impact on hormones and fertility on weight loss.

Thousands of people have been studied in regards to weight and long term obesity. Every single time, the results come back the same. Excessive weight will negatively impact your chances of not only implantation and egg quality, but also your ability to conceive, keep a healthy pregnancy to term and have a healthy baby.

What has been shown in the scientific literature is that 10 percent of weight loss or weight reduction almost doubles the chances of conception of occurring and keeping a healthy pregnancy to term. I’ve seen it with patients in my clinic. I’ve seen it with people who have been infertile for what seemed like forever.

If you are wanting to do intermittent fasting, you absolutely can do that. The only thing that you need to make sure of is that you’re not doing it when trying to conceive so that intermittent fasting has to be happening around say the 120 days of preconception preparation. When you start trying to conceive, you could potentially still do it in the first half of the cycle but not in the second half.

If you have been struggling to conceive and with decisions about your fertility then we encourage you to register for the next #FertilityChallenge, an education and activity series designed to help you make better, more informed choices.
