Calorie needs increase progressively: no extra calories in the first trimester, approximately 340 extra in the second, and about 452 extra in the third trimester, according to ACOG guidelines.
The recommended weight gain depends on your pre-pregnancy BMI. For a normal-weight woman (BMI 18.5-24.9), the target is 25-35 pounds total. Underweight women may need more, while overweight women may need less.
Moderate exercise is encouraged for most pregnancies. ACOG recommends 150 minutes of moderate aerobic activity per week. Always consult your healthcare provider before starting or continuing an exercise program.
