Pregnancy appetite often changes from one trimester to the next. In the first trimester, nausea, stronger reactions to smells, and food aversions may make eating harder. Many people feel hungrier as nausea eases in the second trimester. In the third, energy needs rise, but heartburn or feeling full quickly can make large meals uncomfortable. Cravings and appetite patterns differ, so focus on fluids, nourishing foods, and how you feel.
How Does Appetite Change During Each Trimester?
First Trimester: Why Might You Feel Less Hungry?
During the first trimester, which covers the first 12 weeks of pregnancy, appetite may decrease, increase, or change from day to day. Nausea, vomiting, changes in taste, and sensitivity to food smells can make familiar meals less appealing. You might suddenly dislike coffee, eggs, meat, or foods with strong smells, even if you enjoyed them before pregnancy.
Some pregnant people experience food cravings at this stage, while others struggle to find foods they can tolerate. These changes may be related to hormonal shifts and changes in the senses of smell and taste. According to Pregnancy, Birth and Baby, appetite loss, cravings, and food aversions are common during pregnancy, especially early on.
It can help to eat small amounts more often rather than trying to finish large meals. Plain foods such as toast, crackers, rice, or other foods you tolerate may be easier to manage when nausea is present. Sip water regularly, and try cold foods if the smell of hot meals makes you feel sick.
Pregnancy-related nausea can occur at any time of day, not just in the morning. The NHS notes that nausea and vomiting usually improve by around 16 to 20 weeks, although some people experience symptoms for longer. Contact your pregnancy care provider if symptoms prevent you from eating or drinking adequately.
Second Trimester: Does Appetite Usually Return?
During the second trimester, around weeks 13 to 27, many pregnant people begin to feel better as nausea and fatigue ease. Food that previously seemed unappealing may become easier to tolerate, and hunger may increase. You may find that your usual eating routine becomes more comfortable as your body adjusts to pregnancy.
However, appetite does not always return at the same time for everyone. Some people continue to experience nausea, food aversions, or new cravings. According to the Cleveland Clinic, symptoms such as morning sickness and food cravings or aversions can vary across pregnancy, and many people feel better during the second trimester.
As appetite improves, aim for regular, balanced meals containing protein, whole grains, fruits, vegetables, and sources of calcium. If you previously avoided a nutritious food because of nausea, you can try it again when it becomes easier to tolerate. Suitable alternatives are also helpful when a particular food remains unappealing.
Third Trimester: Why Might You Feel Hungry but Full Quickly?
During the third trimester, which begins around week 28 and continues until birth, your baby's growth increases the energy demands of pregnancy. You may feel hungrier or need more substantial snacks between meals. At the same time, indigestion, heartburn, bloating, and feeling full after eating can make large portions uncomfortable.
The NHS guidance on indigestion and heartburn explains that these symptoms can be related to pregnancy changes, including the growing baby pressing against the stomach. Eating smaller meals more frequently may help you manage discomfort while still getting enough nutrition.
If you feel hungry again soon after eating, try a balanced snack rather than ignoring your hunger. Options such as yogurt, fruit with nuts, whole-grain toast with nut butter, or other foods that fit your dietary needs can provide useful nutrients. If you experience persistent appetite loss, repeated vomiting, or difficulty eating enough, discuss this with your pregnancy care provider.
How Many Extra Calories Do You Need During Pregnancy?
Feeling hungrier can be part of pregnancy, but you do not need to eat twice as much food. Your energy needs generally rise as pregnancy progresses. The U.S. Centers for Disease Control and Prevention (CDC) gives the following general estimates for many pregnant people carrying one baby:
- First trimester: Usually no additional daily calories are needed.
- Second trimester: Around 340 extra calories per day.
- Third trimester: Around 450 extra calories per day.
These estimates are general guidelines, not daily targets that every pregnant person must meet. Calorie needs can depend on pre-pregnancy weight, activity level, health, and whether you are carrying one baby or multiples. Your healthcare professional can help you understand your nutritional needs and appropriate weight gain during pregnancy.
Why Do Pregnancy Cravings and Food Aversions Happen?
Pregnancy may change what you want to eat and which foods you find difficult to tolerate. You might crave salty snacks, sweet foods, fruit, or a particular meal. You may also develop an aversion to a food you previously enjoyed. The reasons for these changes are not fully understood, although hormonal changes and altered taste or smell may contribute.
Cravings alone do not establish that your body is missing a particular nutrient. However, cravings for non-food substances deserve medical attention. According to MedlinePlus, cravings for substances such as dirt, clay, laundry detergent, or ice chips may be associated with pica, which can be linked to low iron levels. Do not eat non-food substances; tell your healthcare professional about these cravings.
How Can You Manage Appetite Changes Safely?
Eating comfortably during pregnancy often requires adjusting meal size, timing, and food choices as symptoms change. Rather than forcing yourself to eat large meals, focus on getting enough fluids and a range of essential nutrients throughout the day.
- Eat smaller, more frequent meals. Several modest meals or snacks may be easier to tolerate than three large meals, especially when nausea or heartburn is present.
- Choose foods you can tolerate. If cooking smells trigger nausea, try cold foods or meals with less noticeable aromas.
- Include a range of nutrients. Choose protein sources, fruits, vegetables, whole grains, and calcium-rich foods or suitable alternatives.
- Drink fluids regularly. If nausea makes drinking difficult, try small, frequent sips rather than drinking a large amount at once.
- Find alternatives for foods you avoid. If you cannot tolerate meat, dairy, or another important food group, ask your healthcare professional or a qualified dietitian about suitable substitutes.
- Continue recommended prenatal supplements. Follow your pregnancy care provider's advice about supplements, and check before adding extra vitamins or minerals.
Try not to judge your nutrition based on a single meal or a single day's appetite. Focus on your overall eating pattern, hydration, symptoms, and the weight-gain guidance provided during prenatal visits.
When Should You Contact Your Pregnancy Care Provider?
Some appetite changes are expected during pregnancy, but persistent or disruptive symptoms should be discussed with a healthcare professional. Contact your doctor, midwife, or obstetrician if you are regularly unable to eat enough, are losing weight, or find that nausea and food aversions are interfering with your daily activities.
Seek prompt medical advice if you cannot keep food or fluids down for 24 hours, have very dark urine or have not passed urine for more than eight hours, feel very weak or faint when standing, have abdominal pain or a fever, or vomit blood. These symptoms can indicate dehydration or another problem that needs assessment.
Your pregnancy care team can review your symptoms, hydration, medical history, weight changes, and nutritional intake to determine whether you need additional support or treatment. You do not have to wait until symptoms become extreme to ask for help.
