Pregnancy & Postnatal Nutrition Guide | ONE Nutrition

Many expecting mothers have heard the old adage that they are "eating for two." However, clinical research shows that for the first trimester, your additional caloric needs are actually zero. This initial phase is about survival—managing fatigue, nausea, and food aversions.

As you transition into the second and third trimesters, your needs increase by approximately 340 and 452 calories per day, respectively.

Navigating these shifting requirements requires more than a standard prenatal vitamin. ONE Nutrition provides the medical nutrition therapy (MNT) and 1-1 care necessary to ensure both mother and baby thrive from pre-conception through the "fourth trimester" of postnatal recovery.

Trimester-Specific Strategy: More Than Just Calories

Every stage of pregnancy has unique biological demands. ONE Nutrition's expert dietitians provide individualized plans that adapt to these changes:

First Trimester: Focus on managing symptoms like morning sickness and establishing a baseline of key nutrients like folic acid (400–800 mcg daily) to prevent neural tube defects.

Second & Third Trimesters: Focus on complex carbohydrates and high-quality proteins. The placenta releases a hormone called hPL, which naturally increases insulin resistance. Our 1-1 care helps you choose low-glycemic index foods to manage this metabolic shift.

Postnatal & Breastfeeding: Lactation is energetically demanding. In the first six months of breastfeeding, mothers require an additional 500 calories per day.

Mastering Gestational Diabetes (GDM) with ONE Nutrition

A diagnosis of Gestational Diabetes (GDM) can be overwhelming, but it is highly manageable with the right expertise. GDM increases the risk of birth complications and "large for gestational age" (LGA) babies.

The good news? Lifestyle modification is the first-line treatment. Research indicates that lifestyle changes alone—focused on nutrition, weight management, and physical activity—are sufficient to control blood glucose in 70% to 85% of women diagnosed with GDM.

How ONE Nutrition helps GDM clients:

Carbohydrate Distribution: Spreading carbohydrate intake throughout the day to avoid postprandial glucose spikes.

1-1 Monitoring: Continuous adjustment of your nutrition plan based on self-glucose monitoring and appetite.

Physical Activity Integration: Guidance on achieving 30 minutes of moderate-intensity exercise daily to improve insulin sensitivity.

The "Big Four" Nutrients You Might Be Missing

Standard vitamins often leave gaps. Personalized care ensures you meet critical targets for:

Iron: Essential for expanding maternal red cell mass. Vegetarian mothers require 1.8 times more iron (approx. 48.6 mg/day) than those who eat meat.

Choline: Critical for brain and spine development; 90-95% of pregnant women do not consume enough.

Iodine: Vital for baby's brain development, often found in lower-than-required amounts in supplements.

DHA (Omega-3s): Critical for fetal nervous system and retina development.
