Hundreds of peer-reviewed studies and published texts show that what you eat directly impacts fertility outcomes. Here are the references and resources that support the Fork-First approach.

"Moderate vitamin D deficiency did not associate with nor exacerbate insulin resistance, androgen levels, inflammation or cardiovascular risk indices in women with PCOS, suggesting that a prospective study on vitamin D deficiency to confirm non-causality is required."
Butler AE, Dargham SR, Abouseif A et al.
"Women's fertility was positively impacted by fruit and vegetable intake, moderate physical activity, and adequate sleep but negatively impacted by obesity and mental stress."
Shujaat T, Ahmed Z, Liaqat S
"Fast foods and saturated fats were significantly associated with lower AMH concentrations and modifying the amount of these dietary components may be an important strategy for increasing the reservation of ovaries in women."
KaboodMehri R, Sorouri ZZ, Sharami SH et al.
"The follicular fluid of women in the treatment group contained significantly higher amounts of EPA and DHA compared to the control group, while the omega-6 fatty acids linoleic, γ-linolenic, dihomo-γ-linolenic, and arachidonic were lower."
Kermack AJ, Wellstead SJ, Fisk HL et al.
"Results showed diet significantly related to improved fertility outcomes (increasing clinical pregnancy, ovulation and menstrual regularity rate; reducing miscarriage rate), reproductive endocrine [increasing sex hormone-binding globulin; decreasing Anti-Müllerian Hormone (AMH), free androgen index (FAI), total testosterone (T)] and clinical hyperandrogenism (hirsutism assessed by Ferriman-Gallwey score) in PCOS."
Shang Y, Zhou H, He R et al.
"The current evidence suggests that greater weight loss and increase in clinical pregnancy, live birth, and natural conception rates after lifestyle intervention compared with no intervention were observed, but it seems no beneficial effect of lifestyle intervention preceding ART was observed on these parameters."
Hoek A, Wang Z, van Oers AM et al.
Zhang X, Liu J, Bai C et al.
"A positive association between a pro-inflammatory diet and self-reported infertility was detected."
Lu J, Tang J, Zou Y et al.
"BMI was highly associated with and predicted IVF failure."
Reyes-Albarracín Y, Porchia LM, Gonzalez-Mejia ME et al.
"Our findings emphasize the need for sensitivity in weight management counseling and addressing psychological distress to prevent unfavorable eating in this population."
Pesonen E, Nurkkala M, Ollila MM et al.
"In the very-low-calorie diet arm, 18% had a biochemical remission of PCOS; this was not the case for any of the participants in the energy deficit arm."
Deshmukh H, Papageorgiou M, Wells L et al.
"Vitamin D affects not only bone-mineral homeostasis, but also many organs and tissues, including the reproductive system, namely the ovaries, uterus, placental tissue, pituitary gland and male reproductive organs."
Kupina AD, Petrov YA
"This study presents compelling evidence to substantiate the link between diverse fatty acids, particularly omega-6 PUFAs, and the risk of female infertility."
Yang Q, Tao J, Jia S et al.
"It is unknown whether administration of a low fat eating plan, regardless of weight loss, will improve reproductive axis function in women with obesity."
Santoro N, Hendricks N, Gibbs L et al.
"The consumption of fruits, vegetables (not cruciferous), dairy products, fish, potatoes, legumes, vitamins (A, C, D and B12), monounsaturated and polyunsaturated fatty acids and minerals (calcium, potassium and magnesium) seems to reduce the risk of endometriosis."
Zaragoza-Martí A, Cabrera-González K, Martín-Manchado L et al.
"These findings suggest after low GL diet habituation, a low GL meal reduces ghrelin and increases glucagon in women with PCOS."
Hoover SE, Gower BA, Cedillo YE et al.
"Among the natural polyphenolic compounds, resveratrol (RES) is known for reducing the effects of declining reproductive power through resisting senility, anti-oxidant and anti-inflammatory, while the molecular mechanism of RES in human ovaries is unclear."
Liang Y, Xu ML, Gao X et al.
"The data suggest that supplementation of n-3 fatty acids could reduce the inflammatory state in women with PCOS."
Tosatti JAG, Alves MT, Cândido AL et al.
"The study found that a higher oxidative balance score is associated with a lower prevalence of female infertility."
Su Z, Ding P, Su W et al.
"Selenium intake regulated the association between infertility and depressive symptoms."
Wang Z, Xiao T, Qi G
"Though BMI remains a predictor of fertility outcomes, alternative markers of adiposity, such as percent body fat, provide distinct information and may be more strongly associated with outcomes than BMI."
Lee IT, Barnhart KT, Hwang WT et al.
"In addition, it induces a reduction in androgenic production, whereas the contextual reduction of fat mass reduced the acyclic production of estrogens deriving from the aromatization in the adipose tissue of the androgenic excess, with an improvement of the LH/FSH ratio."
Cincione RI, Losavio F, Ciolli F et al.
"The energy supply ratio of fat was positively correlated with the risk of PCOS, while the energy supply ratio of monosaturated fatty acids and the energy supply ratio of polyunsaturated fatty acids were negatively correlated with the risk of PCOS."
Zhang X, Wang C, Cheng J et al.
"vitamin D may minimize the risk of female infertility and may be related to the seasons and age."
Wang X, Zhao S, Zhou M et al.
