Pregnancy Weight Gain Calculator

What this means

Recommended pregnancy weight gain depends on your pre-pregnancy body mass index. A healthy-weight woman is generally advised to gain about 11.5–16 kg over the pregnancy, while the ranges are lower for higher starting BMIs and higher for lower ones. Gain is uneven — slow in the first trimester, then roughly steady through the rest — so a simple guide is to compare your gain so far against a fraction of the total that matches your week.

Recommendations

• •Discuss your target range with your healthcare provider — this is a general guideline.
• •Expect most of the weight to come in the second and third trimesters.
• •Focus on nutrient-dense foods rather than 'eating for two' — needs rise, but not by double.

Watch out

• •This is informational and not a substitute for medical advice. Individual recommendations vary.
• •Gain far outside the range, or sudden changes, should be discussed with your provider.
