Frequently Asked Questions
How much weight should I gain during pregnancy?
The recommended weight gain during pregnancy depends on your pre-pregnancy BMI. For underweight women (BMI < 18.5), the recommendation is 12.5-18 kg (28-40 lbs). For normal weight women (BMI 18.5-24.9), it's 11.5-16 kg (25-35 lbs). For overweight women (BMI 25-29.9), it's 7-11.5 kg (15-25 lbs). For obese women (BMI ≥ 30), it's 5-9 kg (11-20 lbs).
How is pregnancy weight gain distributed?
During the first trimester, most women gain 1-2 kg (2-4 lbs). Weight gain accelerates in the second and third trimesters, with an average of 0.4-0.5 kg (0.8-1 lb) per week for women with normal BMI. The weight includes the baby, placenta, amniotic fluid, increased blood volume, breast tissue, and fat stores.
What if I'm gaining too much or too little weight?
If you're gaining weight too rapidly or too slowly, don't try to drastically change your diet without consulting your healthcare provider. Weight gain that's too high or too low can potentially lead to complications, but your provider can help you adjust your nutrition and activity level appropriately for your situation.
Should I diet during pregnancy?
Dieting for weight loss is not recommended during pregnancy. Even if you're overweight, pregnancy is not the time to lose weight. Focus instead on eating nutrient-dense foods and staying within the recommended weight gain guidelines for your BMI category. Consult with your healthcare provider about a healthy eating plan.
