Many women experience a noticeable increase in appetite just before labor begins, fueled by hormonal and physical changes.
Understanding Appetite Changes in Late Pregnancy
As the due date approaches, a pregnant woman’s body undergoes rapid transformations. These changes can significantly influence hunger levels, sometimes leading to an increased appetite. But why does this happen? It’s essential to recognize that the body is preparing for the intense energy demands of labor and delivery. The surge in hunger is often the body’s way of stocking up on fuel.
During the final weeks, progesterone and estrogen levels fluctuate, impacting digestion and metabolism. Progesterone relaxes smooth muscles, including those of the gastrointestinal tract, which can slow digestion earlier in pregnancy. However, as labor nears, these hormone levels shift again, potentially speeding up metabolism and increasing hunger signals.
Moreover, physical activity may decrease due to discomfort or fatigue, but this doesn’t necessarily reduce energy requirements. The body still needs ample calories for uterine contractions and the birthing process itself. This physiological demand often manifests as heightened cravings or an increased appetite just before labor.
Hormonal Influences on Appetite Before Labor
Hormones play a starring role in appetite regulation during pregnancy’s final stage. One key player is oxytocin—commonly called the “love hormone”—which rises sharply as labor begins. Oxytocin stimulates uterine contractions but also has effects on appetite centers in the brain.
Another hormone involved is leptin, responsible for signaling satiety or fullness. Near labor, leptin sensitivity may decrease slightly, making it harder for pregnant women to feel satisfied after eating. This reduced sensitivity can cause more frequent hunger pangs or larger meal portions.
Cortisol levels also tend to spike before labor. While cortisol is known as a stress hormone, it also stimulates gluconeogenesis—the production of glucose from non-carbohydrate sources—raising blood sugar levels and potentially increasing hunger sensations.
These hormonal shifts combined create a perfect storm that can make many women feel hungrier than usual right before they give birth.
How Hormones Affect Digestion and Hunger Signals
The digestive system slows down early in pregnancy due to progesterone but tends to normalize or even speed up near labor because of changing hormone levels like estrogen and oxytocin. This shift can enhance nutrient absorption efficiency and increase energy demands.
The hypothalamus—the brain region controlling hunger—responds to these hormonal cues by adjusting appetite signals. When leptin sensitivity dips and cortisol rises, the hypothalamus triggers stronger hunger signals to ensure adequate calorie intake.
Physical Signs Linked to Appetite Increase Before Labor
Beyond hormones, several physical signs accompany an increased appetite before labor:
- Nesting Instinct: Many women experience a burst of energy coupled with increased food intake as part of their nesting behavior.
- Braxton Hicks Contractions: These practice contractions may stimulate metabolic activity and prompt higher calorie needs.
- Increased Basal Metabolic Rate (BMR): The body’s resting energy expenditure spikes in preparation for childbirth.
- Dilation and Effacement: As the cervix prepares for delivery, subtle physiological changes may heighten overall bodily demands.
All these factors contribute to an intuitive drive toward eating more or choosing specific comfort foods that provide quick energy boosts.
Nesting and Appetite: A Close Connection
The nesting instinct isn’t just about cleaning or organizing; it often involves preparing mentally and physically for birth. Increased food intake during this phase serves as fuel for this intense burst of activity.
This instinctive behavior aligns with evolutionary biology—our ancestors needed extra energy reserves before giving birth to ensure survival during labor’s strenuous process.
The Role of Cravings and Food Preferences Before Labor
Cravings tend to intensify near delivery day. Women might find themselves drawn toward carbohydrate-rich foods such as bread, pasta, or sweets that provide quick glucose bursts essential for muscular endurance during contractions.
Salty snacks are another common craving. Sodium helps retain fluids which might be beneficial as dehydration risk increases during labor due to sweating from contractions.
Interestingly, some women report aversions developing simultaneously with cravings—a complex interplay between taste buds and hormonal influences that shifts food preferences rapidly within days or even hours before birth.
Nutritional Needs: What Should You Eat?
While it may be tempting to indulge every craving without restraint, focusing on nutrient-dense foods ensures both mother and baby remain well-supported:
- Complex Carbohydrates: Whole grains supply sustained energy release.
- Protein: Vital for tissue repair post-delivery; lean meats, beans, nuts are great options.
- Healthy Fats: Omega-3 fatty acids found in fish support brain function.
- Hydration: Water intake is crucial; dehydration can complicate labor progress.
Balancing cravings with wholesome choices helps maintain stable blood sugar levels and prevents fatigue during labor.
The Science Behind Energy Needs During Labor
Labor is physically demanding—uterine muscles contract rhythmically over hours or sometimes days. This muscular activity requires significant ATP (adenosine triphosphate), the body’s primary energy molecule generated mostly from glucose metabolism.
Studies show that women burn roughly 300-500 extra calories per hour during active labor depending on intensity and duration. This expenditure explains why many feel ravenous beforehand—they’re stocking up on glycogen reserves stored in muscles and liver for rapid mobilization when contractions start.
| Labor Stage | Average Duration (Hours) | Estimated Calorie Burn (Calories/Hour) |
|---|---|---|
| Eary Labor | 6-12 | 150-300 |
| Active Labor | 3-6 | 300-500 |
| Transition Phase | <1 hour | 400-600+ |
Understanding these numbers highlights why the body naturally signals increased hunger beforehand—to prepare for this intense caloric demand ahead.
The Importance of Glycogen Stores Before Labor
Glycogen stored in muscles acts as a ready-to-use fuel source during prolonged exertion like childbirth contractions. If glycogen stores are low due to poor nutrition or fasting before labor onset, fatigue sets in faster which can lengthen delivery time or increase complications risk.
That’s why many healthcare providers encourage eating small balanced meals until active labor begins unless medically contraindicated.
Mental Factors Influencing Appetite Before Delivery
Stress and anxiety about childbirth affect appetite differently across individuals—some lose their desire to eat while others experience emotional eating spikes triggered by nervousness or excitement.
The anticipation of intense physical sensations combined with uncertainty often triggers subconscious responses altering usual eating habits temporarily. For some moms-to-be, food becomes a comforting anchor amid overwhelming emotions right before labor kicks off.
Relaxation techniques such as deep breathing or mindfulness can help regulate stress-induced appetite swings so nutritional intake remains adequate without overeating out of anxiety alone.

Frequently Asked Questions
Does Your Appetite Increase Before Labor Due to Hormonal Changes?
Yes, your appetite often increases before labor because of hormonal fluctuations. Hormones like oxytocin, leptin, and cortisol influence hunger signals, making you feel hungrier as your body prepares for the energy demands of labor and delivery.
Does Your Appetite Increase Before Labor as a Way to Stock Up Energy?
Many women experience an increased appetite before labor as the body tries to store energy. This heightened hunger helps fuel the intense physical process of labor and supports uterine contractions needed for childbirth.
Does Your Appetite Increase Before Labor Even If Physical Activity Decreases?
Yes, appetite can increase before labor despite reduced physical activity. Although discomfort may limit movement, the body still requires extra calories to support labor, causing hunger levels to rise regardless of activity changes.
Does Your Appetite Increase Before Labor Because Digestion Speeds Up?
Appetite often rises before labor as digestion speeds up due to hormonal shifts. Early pregnancy slows digestion, but near labor, hormones like estrogen and oxytocin can accelerate metabolism, increasing hunger sensations.
Does Your Appetite Increase Before Labor Due to Changes in Leptin Sensitivity?
Before labor, leptin sensitivity may decrease, making it harder to feel full after eating. This change can cause more frequent hunger pangs or larger meal portions, contributing to an increased appetite just before childbirth.
