Smart Pregnancy Nutrition Strategies
Focus on nutrient-dense foods rather than "eating for two" - you only need 300-500 extra calories daily in later pregnancy.
Adequate protein (75-100g daily) supports fetal brain development and costs less than treating developmental delays.
Key supplements like folic acid, iron, and DHA prevent costly complications - spend $100 to save thousands.

Smart Pregnancy Weight Management
First Trimester Strategy
Focus on prenatal vitamins and managing morning sickness. Weight gain of 1-4 lbs total is normal. Invest $30/month in quality supplements to prevent $50,000+ birth defects.
Second Trimester Nutrition
Increase calories by 340 daily (about $5-8 worth of nutritious food). This steady investment prevents low birth weight, saving potential $100,000+ NICU costs.
Third Trimester Focus
Add 450 calories daily with protein-rich foods. Proper nutrition supports brain development and reduces autism risk, potentially saving $2.4 million in lifetime care costs.
Postpartum Planning
Gradual weight loss (1-2 lbs/week) while breastfeeding burns 500 calories daily, equivalent to a $15 gym session, while saving $2,000+ in formula costs.
