π Quick Answer: Appetite typically increases in the second trimester as nausea subsides and the babyβs growth accelerates. However, some women may experience fluctuating hunger levels throughout pregnancy due to hormonal shifts, metabolism changes, and nutritional demands.
Pregnancy is an exciting journey filled with physical and hormonal changes, and one of the most common questions expectant mothers have is: When does appetite increase in pregnancy? Some women feel constantly hungry, while others struggle with food aversions. In this guide, weβll break down how appetite fluctuates throughout each trimester, why cravings happen, and how to maintain a healthy diet while managing hunger.
1. When Does Appetite Increase in Pregnancy?
Appetite changes throughout pregnancy based on hormonal fluctuations and fetal growth. Hereβs a general timeline of when appetite shifts:
Trimester | Appetite Change | Why It Happens |
First Trimester (Weeks 1-12) | Decreased or fluctuating | Due to nausea, morning sickness, and rising hCG levels |
Second Trimester (Weeks 13-26) | Increased appetite | Nausea subsides, metabolism rises, babyβs growth accelerates |
Third Trimester (Weeks 27-40) | Fluctuating hunger | Baby’s size impacts digestion, metabolism peaks |
π Research Insight: Healthline states that while feeling ravenous may be an early indicator of pregnancy, itβs unlikely for this to be your only symptom, and many women find their appetite actually decreases in the first trimester.

2. Why Does Appetite Fluctuate During Pregnancy?

Hormonal changes play a major role in appetite fluctuations during pregnancy.
Key Hormonal Influences on Hunger:
β Progesterone Increases Food Intake β It boosts appetite, making some women feel constantly hungry.
β Estrogen Suppresses Hunger β It reduces food intake, which can contribute to morning sickness.
β Leptin Resistance Develops β Normally, leptin controls hunger signals, but during pregnancy, the body becomes less responsive, making women feel hungrier.
π Research Insight: A review in PMC found that progesterone increases appetite, while estrogen decreases it, explaining why some women feel starving one day and nauseous the next.

π Research Insight: A study by Boston University reports that during pregnancy, women are resistant to leptin, an endocrine growth factor that reduces appetite and stimulates metabolism. Without leptin’s effects, orexigenic pathways that stimulate hunger are left unopposed, potentially contributing to increased food intake.

3. First Trimester: Appetite Loss vs. Increased Hunger
Is it normal to be hungry every couple of hours during the first trimester?
The first trimester is known for appetite changes, but most women experience decreased hunger due to morning sickness and nausea.
Common First Trimester Eating Challenges:
β Food Aversions β Strong dislikes of certain smells or tastes.
β Nausea & Vomiting β Makes it difficult to eat properly.
β Cravings for Bland Foods β Bread, crackers, and plain rice are often preferred.
β Tips for Managing First Trimester Appetite Loss:
- Eat small, frequent meals to avoid nausea.
- Choose protein-rich snacks like yogurt and nuts.
- Stay hydrated to prevent dehydration-related hunger.
π Research Insight: Pregnancy Birth & Baby notes that food aversions are common in pregnancy, and it is normal to experience either a loss of appetite or a change in food preferences.

4. Second Trimester: When Appetite Begins to Increase
Most women notice a significant increase in appetite during the second trimester because:
β Morning sickness subsides, making eating easier.
β Babyβs growth accelerates, increasing energy needs.
β Metabolism speeds up, burning calories faster.
β Healthy Eating Tips for the Second Trimester:
- Focus on nutrient-dense foods like lean proteins, whole grains, and vegetables.
- Include healthy fats like avocado, nuts, and fish for fetal brain development.
- Avoid excess sugar and processed foods to prevent energy crashes.

5. Third Trimester: Does Hunger Increase Before Labor?
In the third trimester, appetite can fluctuate due to:
β Increased metabolism β The body burns more calories.
β Cravings & Energy Demands β Many women crave carbs as the body prepares for labor.
β Digestive Discomfort β The babyβs size can put pressure on the stomach, reducing hunger.
Signs of Increased Hunger Before Labor:
- Strong carb cravings (pasta, bread, potatoes).
- Sudden bursts of energy, sometimes called nesting mode.
- Desire to eat larger meals.
π Research Insight: A prospective study found a negative correlation of maternal fasting plasma active GLP-1 (known for its anorectic actions) with fetal abdominal circumference measurements during the second trimester, suggesting maternal appetite axis molecules are implicated in the deposition of fetal adipose tissue and energy storage processes, rather than fetal growth.
