Pregnancy calorie calculator
The honest version: we won’t ask your weight. Pick where you are, and we’ll show the evidence-based calories to add to your usual intake — plus the nutrients that matter most.
How it works
Energy needs in pregnancy don’t rise evenly. The Institute of Medicine’s reference intakes put the extra energy at roughly +0 kcal in the first trimester, +340 kcal a day in the second, and +452 kcal a day in the third. We show that addition rather than a total, because the addition is what the evidence pins down — your maintenance level is personal, and it doesn’t need a weigh-in.
Alongside energy, aim for more iron (~27 mg/day), folate (~600 mcg/day, most vital early) and calcium (~1000 mg/day). This is general information, not medical advice.
Common questions
How many extra calories do I need during pregnancy?
None in the first trimester, then about +340 kcal a day in the second trimester and +452 kcal a day in the third, according to the Institute of Medicine. These are additions to your usual intake — not a brand-new total.
Why don’t you ask my weight?
Because you don’t need to know your exact calorie total to eat well in pregnancy — and we don’t believe in putting weight or BMI front and centre. What’s evidence-based is the extra energy each trimester adds, so that’s what we show. Fawna is body-neutral by design.
What else changes besides calories?
Your needs for several nutrients rise — especially iron (to about 27 mg/day), folate (about 600 mcg/day, most important early), and calcium (about 1000 mg/day). Quality matters more than quantity, particularly in the first trimester.
Is this medical advice?
No — it’s general information. Your midwife, doctor or dietitian can tailor guidance to you, especially with multiples, nausea, or a medical condition.
Fawna raises your daily target as your trimester changes and keeps an eye on iron, folate and calcium — no weight question, ever. Join the early-access list.
