When your IVF cycle is booked, the injections, scans and timelines are planned for you. Food is the one part nobody hands you a protocol for, so you end up searching for the "best diet for IVF" late at night. This guide gives you the honest answer, and shows how to turn it into something you can follow on a busy week. If you want a starting point, take our fertility assessment score to see where your nutrition and lifestyle stand, speak to our dietitian about your cycle, or see our pricing.
Quick Answer: What Is the Best Diet for IVF?
No single diet has been proven to improve IVF success. The pattern with the most supportive evidence is a Mediterranean-style diet: vegetables, fruit, whole grains, pulses, nuts, fish and olive oil, with fewer ultra-processed foods. Evidence is largely observational, so it supports overall health and nutritional adequacy for both partners. It cannot replace medical treatment or guarantee a result.
A couple who prepared for two months before their first IVF cycle
One couple came to us about two months before their first IVF cycle. We worked on both partners' diets, including the foods and supplements that mattered for them (chosen alongside their doctor), and we also fixed their sleep routine and built in regular exercise. In the third month, they shared the good news: they had conceived in that very first cycle. They were delighted, partly because it spared them the cost of a second IVF cycle.
Their outcome reflected many factors, including their medical care and individual circumstances, and we cannot say that nutrition alone caused it. Individual outcomes vary, and fertility is influenced by multiple factors. We share it to show what focused preparation can look like.

Why does nutrition matter when you're undergoing IVF?
IVF medication stimulates your ovaries, but your body still has to build, mature and nourish those eggs, and your partner's sperm still develop in the same nutritional environment. Age and ovarian reserve are largely fixed. Nutritional status, blood sugar control, body composition, sleep and stress are the factors you can actually work on.
A systematic review of female dietary patterns and IVF found that higher adherence to a Mediterranean, "profertility" or Dutch preconception diet was associated with pregnancy or live birth in at least one study. The authors were clear that causation cannot be assumed.
So nutrition is best seen as supportive care. It helps correct deficiencies (iron, B12 and vitamin D are common in Indian women), steadies insulin and inflammation, and helps you feel well through a demanding treatment.
Practical takeaway: Diet will not override your clinical plan, but it shapes the body that plan is working with.
What type of diet should couples follow during IVF?
Think pattern, not a list of "fertility foods". A 2018 study in Human Reproduction linked greater Mediterranean-diet adherence with higher odds of clinical pregnancy and live birth after IVF in non-obese women under 35. That is an association, not proof.
In an Indian kitchen, this looks like:
- Protein at every meal: dal, rajma, chana, paneer, curd, eggs, fish or chicken.
- Whole grains and millets: jowar, bajra, ragi, brown rice, whole-wheat roti.
- Vegetables and fruit: at least half your plate, with leafy greens daily.
- Healthy fats: nuts, seeds (flax, sesame, pumpkin), olive or cold-pressed oils, oily fish.
- Less of: sugary drinks, deep-fried snacks, refined flour, packaged foods, alcohol.
Men need this too. Sperm are made over roughly three months, so his plate matters as much as hers.
| Do more of | Do less of |
|---|---|
| Home-cooked meals with protein and fibre | Ultra-processed and packaged foods |
| Nuts, seeds, pulses, oily fish | Sugary drinks and refined carbohydrates |
| Water, herbal teas, buttermilk | Alcohol; excess caffeine (follow your clinic's limit) |
| Regular meal timings | Crash dieting or long fasting gaps |
Can diet and lifestyle improve IVF success?
They can improve the things that support treatment, which is different from promising a better outcome. Realistic goals include:
- Correcting deficiencies before stimulation begins.
- Improving insulin sensitivity, especially with PCOS or insulin resistance.
- Reaching a healthy body composition without crash dieting.
- Better sleep, stress management and moderate exercise.
- Stopping smoking and limiting alcohol, for both partners.
What diet cannot do is raise AMH, reverse age-related decline in egg quality or replace your fertility specialist's protocol. Honest nutrition advice is clear about both sides, and so are we.
When should couples start diet and lifestyle changes?
Ideally three months before your cycle, and no later than one month before. Eggs spend roughly three months in their final stages of growth before ovulation, and sperm take about the same time to develop, so changes started today are most relevant to a cycle about three months away.
If your cycle is closer, start anyway. A few weeks of better protein intake, steadier blood sugar and corrected deficiencies still helps you feel better through stimulation, and nothing is lost by starting late. Do not make drastic changes or start supplements mid-cycle without checking with your clinic.
What should you eat in each phase of an IVF cycle?
Needs shift across the cycle. This is a general guide, so your plan should always follow your clinic's instructions.
| Phase | Focus | Foods to include |
|---|---|---|
| Preparation (about 3 months before) | Build nutritional reserves, correct deficiencies | Dal, eggs or paneer, leafy greens, nuts, seeds, curd, seasonal fruit, fish |
| Stimulation (injections and scans) | Protein, hydration, comfort as ovaries enlarge | Small frequent meals, khichdi, dal, curd, soups, fluids; fibre to ease constipation |
| Egg retrieval and recovery | Gentle, iron-rich, hydrating | Lentil soups, eggs, leafy greens, coconut water, light home-cooked meals |
| Transfer and two-week wait | Steady blood sugar, calm digestion | Balanced plates with protein, whole grains, vegetables; no food is proven to "help implantation" |
During stimulation, bloating and constipation are common. If you notice rapid weight gain, severe bloating or breathlessness, call your clinic, because these can signal ovarian hyperstimulation.
Which nutrients matter for egg quality and sperm health?
For eggs: Egg quality is driven mainly by age, and no food or supplement reliably improves it. Nutrition supports the surrounding environment:
- Folate and B12 (B12 is often low in vegetarians)
- Iron and vitamin D, which are best tested rather than guessed
- Omega-3 fats from fish, walnuts, flax and chia
- Antioxidant-rich colourful vegetables and fruit
- Adequate protein and steady blood sugar
Supplements such as CoQ10 have mixed evidence, so decide on them with your doctor.
For sperm count and concentration: Zinc, selenium, folate, omega-3 and antioxidants (vitamins C and E) are all linked to semen quality, and a pattern rich in vegetables, nuts and fish is better than a Western-style one. In a 14-week randomised trial presented at ESHRE, 119 healthy young men who added 60 g of mixed almonds, hazelnuts and walnuts daily showed improvements in sperm count, motility and morphology. The men were healthy and apparently fertile, so the findings cannot be applied to every man with abnormal parameters.
Men should also cut back on alcohol, avoid smoking and tobacco, and avoid prolonged heat exposure such as laptops on the lap or long hot baths.
How do we build a diet plan around your life?
A generic IVF diet fails because nobody eats generically. At Health Hatch, our dietitians build a fertility diet plan around your eating style, likes and dislikes and daily schedule, so it still works on travel days and long clinic mornings. We add a grocery list so shopping is simple and sticking to the plan takes less effort.
For clients abroad, we adapt the plan to what is available locally: nutrient-dense foods from your region, simple one-pot meals built around them, and a local grocery list. Whether you are in Dubai, London or Toronto, the plan uses ingredients you can actually buy.
Frequently Asked Questions
Is there a specific diet that guarantees IVF success?
No. No diet has been shown to guarantee a pregnancy or live birth. A Mediterranean-style pattern has the best supporting evidence, but it improves health and nutritional adequacy rather than ensuring a specific result.
Should I follow a high-protein or low-carb diet during IVF?
Adequate protein is useful, but strict low-carb or keto diets are not recommended without supervision. Evidence on carbohydrate restriction in IVF is limited, and rapid weight change is not advisable during treatment.
Which foods should I avoid during IVF?
Limit alcohol, tobacco, sugary drinks, ultra-processed foods and excess caffeine. Avoid raw or undercooked animal foods and unpasteurised dairy for food safety. Check your clinic's specific advice on herbal teas and supplements.
Can I eat papaya, pineapple or sesame after embryo transfer?
There is no good evidence that these foods help or harm implantation, and normal food portions are not a concern. Focus on balanced meals instead, and ask your clinic if you have specific worries.
Do I need supplements for IVF?
Often a prenatal with folate is advised, but other supplements should be based on blood tests and your doctor's advice. More is not better, and some products can interfere with treatment.
Does my partner need to change his diet too?
Yes. Sperm development takes roughly three months, so his diet, alcohol intake, smoking and sleep matter alongside hers. Male factors contribute to a substantial share of infertility, so both partners benefit.
What if my IVF cycle is only a few weeks away?
Start with what is simple: regular protein-rich meals, hydration, less alcohol and processed food. Avoid drastic changes, and speak to a dietitian who can work around your clinic's schedule.
