Pregnancy care is individual. Everything below is general background to help you follow the plan your midwife or doctor gives you — it does not replace it. If any advice here conflicts with theirs, follow theirs.
Energy: less extra than people think
"Eating for two" is the most persistent myth in pregnancy nutrition. Energy needs rise gradually, and mostly late. Commonly cited figures are around 340 extra calories a day in the second trimester and 450 in the third, with little to no increase in the first. That is a sandwich, not a second dinner.
Recommended weight gain varies considerably depending on your starting weight, and this is one of the things your care team will set individually.
The nutrients that get the most attention
| Nutrient | Why it matters | Common sources |
|---|---|---|
| Folate / folic acid | Neural tube development in early pregnancy | Supplement, leafy greens, legumes |
| Iron | Blood volume rises substantially | Red meat, legumes, eggs, with vitamin C |
| Calcium | Skeletal development | Dairy, fortified alternatives, tahini |
| Iodine | Thyroid and brain development | Iodised salt, dairy, fish |
| Vitamin D | Bone health; commonly low | Supplement, oily fish, eggs |
| Omega-3 (DHA) | Brain and eye development | Oily fish within safe limits |
Which of these you actually need to supplement — and at what dose — depends on your blood results and history. That decision belongs with your clinician, not an article.
Foods usually avoided
- Raw or undercooked meat, fish and eggs
- Unpasteurised milk and soft cheeses made from it
- High-mercury fish such as swordfish, shark and king mackerel
- Liver and high-dose vitamin A supplements
- Alcohol — no amount is established as safe
Local guidance differs on some specifics, which is another reason to check with your own provider rather than an international list.
Kiva's note
In the first trimester, nausea often decides what you can eat. Small, frequent, bland meals and staying hydrated beat any perfect plan you cannot keep down.
Movement and tracking
For most uncomplicated pregnancies, regular moderate activity is encouraged and associated with better outcomes — but the type and intensity should be cleared with your provider, particularly if you were not active before.
A note on tracking: pregnancy is not the time for calorie deficits or weight-loss targets. If you use an app, use it to track symptoms, hydration, movement and appointments rather than restriction.
Contact your provider promptly if you have bleeding, severe or persistent vomiting, severe headaches, vision changes, sudden swelling, abdominal pain, or reduced fetal movements. These are not things to look up — they are things to call about.
Frequently asked questions
Do you need to eat for two in pregnancy?
No. Energy needs rise only modestly and mostly in the later trimesters — commonly cited as roughly 340 extra calories a day in the second trimester and 450 in the third. Your own guidance should come from your doctor or midwife.
Which supplements are usually recommended?
Folic acid before and in early pregnancy, and vitamin D, are the most commonly recommended. Iron and others are prescribed based on blood results. Never start or stop a supplement in pregnancy without medical advice.
How much caffeine is allowed in pregnancy?
Guidance is generally lower than for other adults, commonly around 200 mg a day, but you should confirm the figure that applies to you with your healthcare provider.

How much protein do you actually need?
Grams per kilo, not percentages — and why how you spread protein across the day matters more than the exact daily total.
