Many moms-to-be ask themselves how many extra pounds are allowed and still considered “normal“. But there is no “one size fits all” approach to weight gain, because every pregnancy takes an individual course.
A woman who was fairly slim before her pregnancy does not have to worry about gaining weight. If your BMI (Body Mass Index)* before pregnancy was below 18.5, a weight gain of 12.5–18 kg during pregnancy is recommended. Women with normal weight (BMI 18.5–24.9) should preferably have a weight gain in the range of 11.5–16 kg. Those with a BMI between 25.0–29.9 even before pregnancy should take care not to gain too much weight (about 7–11.5 kg).
