What to Eat While Trying to Conceive and Lose Weight
If you are trying to conceive and want to lose weight, you may feel caught between two completely different sets of advice.
One tells you to eat less, cut carbohydrates and lose weight quickly. The other tells you that every food needs to support your fertility and that restricting anything could be harmful.
The reality is more balanced.
You can potentially lose weight while trying to conceive by creating a modest, personalised calorie deficit while continuing to eat regular, varied and nourishing meals. You do not need a perfect “fertility diet”, expensive superfoods or a cupboard full of supplements.
What should you eat while trying to conceive and lose weight?
A balanced TTC weight-loss diet should include:
Regular meals
A useful source of protein throughout the day
Fruit and vegetables
Fibre-rich carbohydrates
Appropriate portions of dietary fats
Enough food to support your health and activity
Meals that you genuinely enjoy and can repeat
The aim is to reduce your overall calorie intake without cutting out important food groups or making eating so complicated that you cannot sustain it.
Your personal needs will depend on your starting weight, activity level, health, fertility treatment and relationship with food.
Is there a special fertility diet for weight loss?
There is no single diet that has been proven to guarantee pregnancy.
You do not automatically need:
Special “fertility foods”
A gluten-free or dairy-free diet
A completely sugar-free diet
Daily green juices
Expensive organic ingredients
A long list of supplements
Perfect meals every day
Unless you have an allergy, diagnosed medical condition or specific professional advice, removing entire food groups can make eating more difficult without necessarily improving your chances of conception.
The NHS Eatwell Guide recommends eating a variety of foods across the main food groups. You do not need to achieve a perfect balance at every individual meal. What you eat across the day and week matters more.
Build your meals around protein
Including protein can help your meals feel more satisfying and support the maintenance of muscle while you lose weight.
Simple protein options include:
Eggs
Chicken and turkey
Fish
Lean meat
Greek-style yoghurt
Cottage cheese
Milk
Tofu
Beans
Chickpeas
Lentils
Protein does not need to mean eating plain chicken and broccoli every day.
You could have eggs on toast for breakfast, a tuna jacket potato for lunch and chilli with rice for dinner. These are normal meals that can provide protein while fitting into a balanced weight-loss plan.
You do not need to stop eating carbohydrates
Carbohydrates are not the reason that you have struggled to lose weight.
Foods such as potatoes, bread, rice, pasta, oats and cereal provide energy and can contribute vitamins, minerals and fibre. They can all fit into a TTC weight-loss diet.
Where appropriate, choose higher-fibre options such as:
Porridge oats
Wholemeal or higher-fibre bread
Potatoes with their skins
Wholewheat pasta
Brown or mixed rice
Higher-fibre cereals
That does not mean every carbohydrate has to be brown, wholegrain or “clean”. White bread, ordinary pasta and other foods you enjoy can still fit.
Portion size and your overall intake matter more than banning one type of food.
Include fruit and vegetables without making meals miserable
Fruit and vegetables provide fibre and a range of vitamins and minerals.
Fresh produce is not your only option. Frozen vegetables, tinned vegetables, supermarket basics and tinned fruit in juice can all be useful.
Affordable and easy options include:
Bananas
Apples
Frozen berries
Carrots
Peas
Sweetcorn
Tinned tomatoes
Frozen mixed vegetables
Beans and lentils
You do not need to force yourself to eat enormous salads if you do not enjoy them.
Vegetables can be added to pasta sauces, curries, soups, omelettes, wraps and familiar family meals. Fruit can be used as a snack, added to breakfast or blended into a smoothie.
Do fats need to be avoided when losing weight?
No. Dietary fats are part of a balanced diet.
Sources include:
Nuts and seeds
Olive or rapeseed oil
Avocado
Oily fish
Nut butter
Fat contains more calories per gram than protein or carbohydrates, so portions can make a noticeable difference when weight loss is the goal. This does not mean fat needs to be eliminated.
For example, nut butter can fit into your plan, but repeatedly adding several unmeasured spoonfuls may make it harder to maintain a calorie deficit.
The answer is awareness, not fear.
What does a day of TTC weight-loss meals look like?
There is no universal meal plan, but a straightforward day might look like:
Breakfast
Porridge made with milk, topped with fruit and yoghurt.
Lunch
A chicken or bean wrap with salad, followed by fruit.
Dinner
A simple chilli made with lean mince or beans, served with rice and vegetables.
Snacks
Options could include yoghurt, fruit, eggs, cheese, popcorn or a planned smoothie.
This is only an example. The portions and total amount of food need to be adapted to your calorie requirements, preferences and health.
Can smoothies help with weight loss while TTC?
Smoothies can be a convenient way to include fruit, protein and other useful ingredients, especially when mornings are busy or you struggle to eat breakfast.
However, a smoothie is not automatically balanced or suitable for weight loss.
A large smoothie containing several portions of fruit, juice, full-fat yoghurt, nut butter, honey and oats can provide far more calories than expected.
A more balanced smoothie could include:
One main portion of fruit
A source of protein
Milk or an appropriate alternative
A measured amount of any higher-calorie ingredients
Ice or water to adjust the consistency
The goal is not to create a magical fertility drink. It is to create something enjoyable and filling that fits into the rest of your day.
Do you need to count calories?
You do not have to count calories to lose weight, but understanding your overall intake can be helpful.
Some women enjoy the clarity of tracking. Others find it overwhelming, stressful or difficult to sustain.
Other options include:
Following a personalised meal plan
Using consistent portions
Planning your meals before the day begins
Repeating a few reliable breakfasts and lunches
Keeping easy meals available for busy days
Monitoring your progress and adjusting gradually
If you use a calorie target, it should be calculated around you. Do not assume that a very low target found online is safe or appropriate.
How often should you eat while trying to conceive?
There is no required number of meals for fertility or weight loss.
Some women feel best eating three regular meals. Others prefer three meals and one or two snacks. The right structure is the one that helps you manage hunger, meet your nutritional needs and remain consistent.
Skipping meals is not automatically harmful, but it can backfire if it leaves you ravenous and eating far more later.
Pay attention to your own patterns.
If you regularly lose control around food in the evening, the answer may not be more discipline. You may simply need a more substantial breakfast or lunch.
What foods should you avoid while trying to conceive?
Trying to conceive does not mean that you need a huge list of forbidden foods.
However, because you could become pregnant, it is sensible to familiarise yourself with current NHS pregnancy and preconception guidance. This includes advice about alcohol, supplements, food safety and vitamin A.
The NHS recommends taking 400 micrograms of folic acid daily when trying to become pregnant, ideally beginning three months before pregnancy, and continuing during the first 12 weeks. Some people need a higher prescribed dose because of their health, medication or medical history.
The NHS also provides current advice about vitamin D and warns against taking cod liver oil or supplements containing vitamin A during pregnancy.
Read the full NHS guidance on vitamins and supplements when trying to conceive and speak to your GP or fertility clinic about your individual needs.
Do not stop prescribed medication or begin high-dose supplements without professional advice.
Can you still eat chocolate, takeaways and meals out?
Yes.
Foods do not become forbidden because you are losing weight or trying to conceive.
Chocolate, cake, takeaways and restaurant meals can fit into a balanced diet. The frequency and portions may need consideration, but you do not need to avoid every social occasion.
Trying to be perfect often creates an all-or-nothing pattern:
You follow an extremely strict plan.
Real life happens.
You eat something that was not on the plan.
You feel that you have failed.
You abandon the plan and promise to restart on Monday.
A flexible plan helps you return to your normal routine at the next meal without guilt or punishment.
What if the scales are not moving?
Before cutting your calories dramatically, look at what is happening across the whole week.
Consider:
Are portions larger than you realise?
Are drinks adding calories?
Are weekends very different from weekdays?
Are you regularly picking while cooking?
Are you eating enough earlier in the day?
Has your general movement decreased?
Have you been consistent for long enough to assess the trend?
Also remember that scale weight can fluctuate because of your menstrual cycle, hydration, digestion, carbohydrate intake and salt.
One weigh-in does not tell you whether your plan is working.
A simple TTC weight-loss plate
A useful starting point for many main meals is:
A source of protein
A portion of carbohydrates
Fruit or vegetables
An appropriate amount of fat or sauce
The exact proportions should suit your body and goals, but this structure can remove much of the confusion.
You do not need to combine every fertility nutrient in every meal. You are allowed to eat ordinary food.
Frequently asked questions
Can I diet while trying to conceive?
A moderate, balanced weight-loss plan may be appropriate for some women while trying to conceive. Aggressive dieting and severe restriction should be avoided. Speak to your GP or fertility team if you have a medical condition, irregular periods, a history of disordered eating or are undergoing treatment.
What is the best breakfast for weight loss while TTC?
There is no single best breakfast. A meal containing protein and fibre may help with fullness. Examples include eggs on toast, porridge with yoghurt and fruit, or a balanced smoothie.
Should I cut out sugar while trying to conceive?
You do not need to remove all sugar. Foods high in added sugar can be eaten less frequently or in smaller portions, but a completely sugar-free diet is not required for everyone trying to conceive.
Are carbohydrates bad for fertility?
Carbohydrates are a major source of energy and can form part of a healthy, balanced diet. There is no general requirement to remove carbohydrates while TTC.
How much protein should I eat while trying to conceive?
Protein requirements vary according to body size, health, activity and overall diet. Rather than relying on a universal target, begin by including a useful protein source throughout the day and seek individual advice where needed.
What should I eat during the two-week wait?
Continue with regular, balanced meals and follow any advice given by your fertility clinic. Avoid beginning an extreme diet during the two-week wait. If you receive a positive pregnancy test, seek advice about adapting your nutrition and weight-loss goal.
Make your plan simpler, not stricter
Trying to conceive already brings enough pressure. Your food does not need to become another daily test that you can pass or fail.
Successful weight loss is rarely about discovering the one food you need to remove. It is about creating a structure that helps you eat appropriately and consistently within your real life.
Normal meals can work. Meals out can fit. Imperfect weeks can still move you forward.
