Why Maternal Nutrition and Weight Management Matter
Good maternal nutrition and healthy weight gain during pregnancy positively influence the health of your baby, reducing the risk of complications such as gestational diabetes, pre-eclampsia, small or big babies and preterm birth. Maintaining a healthy weight during pregnancy can also help manage labour more effectively and support postpartum recovery.
Excessive or insufficient weight gain during pregnancy can have long-term health implications for both mother and child, increasing the risk of obesity, metabolic disorders, and cardiovascular issues later in life.
The updated NICE guideline (NG247) replaces older recommendations, reflecting the latest evidence to ensure better health outcomes.
What Is Healthy Weight Gain?
Weight gain during pregnancy varies based on pre-pregnancy body mass index (BMI).
The general recommendations are as follows:
- Underweight (BMI <18.5): 12.5 - 18 kg (2 st to 2 st 12 lbs)
- Normal weight (BMI 18.5 - 24.9): 11.5 - 16 kg (1 st 11 lbs to 2 st 7 lbs)
- Overweight (BMI 25 - 29.9): 7 - 11.5 kg (1 st 1 lbs to 1 st 11 lbs)
- Obese (BMI ≥30): 5 - 9 kg (11 lbs to 1 st 6 lbs)
It's also important to remember that your body’s needs will change throughout each stage of pregnancy, from the first trimester to the third. To learn more about what to expect during each stage, take a look at my article on Understanding the Three Trimesters of Pregnancy.
The Role of Exercise in Pregnancy
Staying active during pregnancy offers numerous benefits, including improved mood, better cardiovascular health, and reduced risk of pregnancy-related complications - all while offering the best preparation of the body for labour and recovery.
The NICE guidance recommends that pregnant women engage in moderate-intensity physical activity for at least 150 minutes per week, spread across several days.
Safe Exercise Options Include:
- Brisk walking
- Swimming or water aerobics
- Prenatal yoga or Pilates
- Stationary cycling
- Light weights with proper technique
- Prenatal yoga and stretching
Precautions:
- Avoid high-impact activities, contact sports, or exercises with a risk of falling.
- Listen to your body - if you feel dizzy, breathless, or experience pain, stop exercising immediately.
Always consult with a healthcare provider before starting any new exercise regimen, especially if you have pregnancy-related complications.
