There are no official guidelines to assist in answering this question. I will search for relevant research papers instead.
From the Research
Diet and In Vitro Fertilization (IVF)
- There is no direct evidence to suggest that One Meal A Day (OMAD) is recommended prior to In Vitro Fertilization (IVF) 1, 2, 3, 4, 5.
- Studies have investigated the impact of various dietary patterns on IVF outcomes, including the Mediterranean diet, which has been associated with improved embryo yield and higher adherence to a 'profertility' diet or a Dutch 'preconception' diet, which may be associated with pregnancy or live birth after IVF treatment 4, 5.
- A systematic literature review found that higher adherence to certain dietary patterns, such as the Mediterranean diet, may be associated with improved IVF outcomes, but the evidence is limited and heterogeneous, and more research is needed to confirm these findings 4.
- Another study found that a diet modification program with increased intake of certain nutrients, such as lactose, fiber, and minerals, and lower intake of glucose and lipid, may control the prevalence of adverse maternal and neonatal outcomes in IVF-pregnant women 2.
- A prospective controlled study found that oral multinutrient supplementation may have a positive effect on Follicular Output Rate (FORT) and lower use of gonadotropin, but more research is needed to confirm these findings 3.
Dietary Recommendations for IVF
- There is no consensus on a specific dietary recommendation for women undergoing IVF, and more research is needed to determine the optimal dietary pattern for improving IVF outcomes 4.
- A study found that infertile women with greater adherence to the Mediterranean diet pattern were likely to obtain more embryos available in IVF cycle, suggesting that this dietary pattern may be beneficial for IVF outcomes 5.
- Another study found that a diet-based intervention during pregnancy was efficient in improving outcomes for both mother and baby, but the study did not specifically investigate the impact of diet on IVF outcomes 2.
