Welcome to the fourth month of pregnancy—an exciting milestone that marks the beginning of your second trimester. Often referred to as the “honeymoon phase” of pregnancy, this stage brings welcome relief for many moms-to-be. Morning sickness usually starts to fade, energy levels improve, and your growing baby begins an incredible phase of rapid growth.
A healthy fourth month pregnancy diet becomes even more important because your baby’s bones are strengthening, muscles are developing, facial features are becoming more defined, and the placenta is working efficiently to supply oxygen and nutrients. At the same time, your body requires more protein, iron, calcium, healthy fats, and other essential nutrients to support your baby’s development and maintain your own health.
Many women also notice an increase in appetite during the fourth month. While it’s natural to feel hungrier, this doesn’t mean you need to “eat for two.” Instead, focus on eating nutrient-dense meals that provide lasting energy and support healthy pregnancy weight gain.
In this comprehensive guide, you’ll learn:
- What to eat during the fourth month of pregnancy
- Essential nutrients for the second trimester
- Best fruits, vegetables, proteins, and dairy foods
- Foods to avoid during the fourth month
- A sample Indian pregnancy diet chart
- Tips for managing common second-trimester symptoms
- Frequently asked questions about fourth-month pregnancy nutrition
Whether this is your first pregnancy or you’ve experienced pregnancy before, following a balanced diet now can help support a healthier pregnancy and prepare your body for the months ahead.
Why Nutrition Is Important During the Fourth Month of Pregnancy
The fourth month marks the beginning of one of the fastest growth phases in pregnancy. While your baby’s organs are already formed, they continue maturing rapidly, and your baby’s skeleton, muscles, brain, and nervous system need a steady supply of nutrients.
Eating a nutritious diet during the fourth month helps:
- Support rapid fetal growth.
- Strengthen developing bones and teeth.
- Promote healthy brain and nervous system development.
- Build healthy muscles and connective tissues.
- Increase maternal blood production.
- Reduce the risk of iron-deficiency anemia.
- Support healthy pregnancy weight gain.
- Maintain maternal energy and immunity.
This is also a good time to establish healthy eating habits that will carry you through the remainder of your pregnancy.
What Happens During the Fourth Month of Pregnancy?
By the end of the fourth month, your baby measures approximately 10–12 cm (about the size of an avocado) and weighs around 100 grams. Although still small, your baby is becoming much more active.
Baby’s Development During Month Four
Several exciting milestones occur during this month:
- Bones continue hardening.
- Muscles become stronger.
- Arms and legs grow longer.
- Facial expressions begin developing.
- Hair starts forming on the scalp.
- Fingerprints begin developing.
- The baby starts swallowing amniotic fluid.
- The digestive system becomes more active.
- The kidneys continue producing urine.
- The placenta fully supports your baby’s nutritional needs.
These developments require increased amounts of protein, calcium, iron, healthy fats, vitamin D, and other key nutrients.
Changes in Your Body
Many women notice positive changes during the second trimester.
Common experiences include:
- Increased appetite
- Improved energy levels
- Reduced nausea
- Gradually growing baby bump
- Round ligament pain
- Mild backache
- Occasional constipation
- Increased blood circulation
- Nasal congestion
- Healthy pregnancy weight gain
Some women may also begin to feel the first subtle baby movements toward the end of the fourth month, although this varies from person to person.

Rather than eating larger portions, aim to eat nutrient-dense meals that support healthy fetal growth, maternal energy, and appropriate pregnancy weight gain.

Common Nutrition Mistakes to Avoid During the Fourth Month
As your appetite improves, it’s important to maintain healthy eating habits instead of simply eating more.
Eating Too Many Empty Calories
It’s easy to satisfy cravings with sweets and fast food, but these foods provide very little nutrition.
Limit:
- Sugary drinks

Drinking Too Little Water
Adequate hydration supports digestion, circulation, and amniotic fluid levels.
Drink water consistently throughout the day, even if you don’t feel thirsty.
Depending on Processed Convenience Foods
Busy schedules sometimes make packaged foods tempting.
Instead, prepare simple meals using:
- Whole grains
