When can you start losing weight after pregnancy?
After pregnancy, the body needs time to recover and heal. How quickly weight changes varies from person to person, and many people lose weight naturally during the first few months after giving birth as the uterus returns to its normal size and excess fluid leaves the body.
During the first period after giving birth, it is often more important to focus on recovery, sleep, nutritious food and establishing routines in your new everyday life than to actively try to lose weight. For people who are breastfeeding, it is also important to get enough energy and nutrients.
After around six months, it may be a good time to review your diet, physical activity and other lifestyle habits if your weight has not started to decrease or if you would like support with sustainable weight loss. If you are living with overweight or obesity, it can be helpful to discuss weight loss with a healthcare professional once your recovery is underway and everyday life has become more stable. Sustainable weight loss is usually based on gradual changes to eating habits, physical activity and other lifestyle habits rather than quick solutions.
Realistic expectations and a long-term perspective can make it easier to create habits that last over time.
How do breastfeeding and weight loss interact?
Breastfeeding increases the body's energy requirements and means that the body uses energy to produce breast milk. At the same time, the need for fluids and nutritious food increases to support both your own health and milk production.
How breastfeeding affects weight varies from person to person. Some people find that their weight decreases more quickly while breastfeeding, while others notice that their weight changes more slowly or remains unchanged despite breastfeeding. Hormonal factors, sleep, recovery, physical activity and eating habits can all affect changes in weight.
During breastfeeding, it is important to focus on nutritious meals and getting enough energy. Strict diets or large calorie deficits are generally not recommended, as the body needs energy and nutrients for recovery and breastfeeding.
Protein-rich foods, wholegrains, vegetables, fruit, pulses, fish and other nutrient-dense foods can contribute to both fullness and sufficient nutrient intake during this period.
How can lack of sleep affect weight after pregnancy?
Lack of sleep is common during the time when you have a baby and can affect energy levels, appetite and everyday habits. Many new parents find it more difficult to prioritise healthy eating habits and physical activity when sleep is limited.
Research shows that lack of sleep can affect the body's regulation of hunger and fullness. At the same time, tiredness can increase cravings for energy-dense foods and make it more difficult to plan meals, be physically active or recover between everyday activities.
For many new parents, the challenge is not knowing what is healthy, but making new habits work in an everyday life where lack of sleep, breastfeeding, recovery, work and caring for a young child also need to fit in. It is therefore often more helpful to focus on small, realistic changes that can be made in everyday life than to aim for quick results or perfect routines.
Can you use weight loss medicines while breastfeeding?
Weight loss medicines are generally not recommended while breastfeeding. For GLP-1-based treatments, such as semaglutide and tirzepatide, knowledge about their use during breastfeeding is still limited, and treatment is therefore usually advised against during this period.
When breastfeeding, it is important that both the breastfeeding person and the baby get enough energy and nutrients. If weight loss is being considered, the primary recommendation is therefore to focus on healthy lifestyle habits and recovery until breastfeeding has ended.
For people considering medical weight treatment after pregnancy, it is important to discuss treatment options with a doctor. The assessment always needs to be tailored to the individual's health, breastfeeding situation and future pregnancy plans.
If you are planning another pregnancy, it is also important to inform your healthcare professional. For some weight loss medicines, it is recommended that treatment is stopped some time before pregnancy, in accordance with current product information and medical recommendations.
How can you rebuild your body through diet and physical activity after giving birth?
After pregnancy and giving birth, the body needs time to recover. For many people, the first period is not about losing weight as quickly as possible, but about regaining strength, energy and function in everyday life.
Diet and physical activity play an important role in recovery. Regular meals with enough protein can help preserve and rebuild muscle mass, while providing the body with the energy and nutrients needed for healing and recovery. Vegetables, fruit, wholegrains, pulses, fish and other nutrient-dense foods can contribute to good nutrient intake.
When it comes to physical activity, it is often a good idea to start gradually based on your own circumstances and the recommendations you have received from your healthcare professional. Walking, pelvic floor exercises and lighter strength training may be suitable first steps. Over time, exercise can gradually be increased to strengthen muscles, improve fitness and make it easier to return to everyday activities and exercise.
For many women, focusing on recovery, strength and function can create better conditions for both health and weight loss in the longer term.
Frequently asked questions about losing weight after pregnancy
Why am I not losing weight even though I am breastfeeding and eating well?
How weight changes after pregnancy varies greatly from person to person. Although breastfeeding increases the body's energy requirements, it does not automatically lead to weight loss. Hormones, sleep, stress, physical activity, genetic factors and recovery after giving birth can all affect changes in weight.
Many new parents also get less sleep and have less time for recovery, which can affect appetite, energy levels and everyday habits. It is therefore not unusual for weight loss to be slower than expected even if you are breastfeeding and trying to eat healthily.
When can I start exercising after giving birth?
When you can resume exercise depends on how your pregnancy and birth went and how your recovery is progressing. Lighter physical activity, such as walking, can often be started early based on your own ability. More intensive exercise should be adapted to your body's recovery and the advice you have received from healthcare professionals. If you are unsure, it may be helpful to discuss exercise with a midwife or physiotherapist.
Can abdominal muscle separation affect exercise after pregnancy?
Yes. During pregnancy, the rectus abdominal muscles are often stretched, and for some people, abdominal muscle separation (diastasis) remains after giving birth. For many, the condition gradually improves over time, but some may need adapted exercise to regain strength and function in the core muscles. If you experience problems, it may be helpful to contact a midwife or physiotherapist for individual advice.
