Weight gain during perimenopause is common and 100% normal. Here’s why you might be gaining weight during this transition—and how to navigate this symptom.
Maybe you’re keeping your same habits, but starting to notice weight gain as you’re getting older—particularly as you reach your mid 40’s. While perimenopause is known for symptoms like hot flashes and mood swings , perimenopause weight gain is very real. This symptom can be frustrating, emotional, and even negatively affect your overall health. Here’s what you need to know about perimenopause weight gain causes, how long it lasts, and how to navigate it.
What causes perimenopause weight gain? Many of the horrible perimenopause symptoms happen because of hormonal fluctuations during this transition period; however, perimenopause weight gain doesn’t happen only because of these hormonal changes, but rather a mix of hormonal, aging, genetic, and lifestyle factors.
According to a review of literature on weight gain at menopause, “while weight gain per se cannot be attributed to the menopause transition, the change in the hormonal milieu at menopause is associated with an increase in total body fat and an increase in abdominal fat.”
What does this mean? The hormone changes that happen during perimenopause—like fluctuations in estrogen and perimenopause—are not solely responsible for overall weight gain. Instead, perimenopause weight gain comes from a mix of factors, like:
Redistributed fat: As estrogen decreases, the body may redistribute fat to the abdominal area, leading to an increase in visceral fat.Slowed metabolism: As we age, our metabolism slows down, making it easier to gain weight and harder to lose it.Changes in sleep patterns: More erratic and less frequent sleep—often caused by other perimenopause symptoms—can affect dietary choices and physical activity levels.High stress: Stress, which is common during this transition, can trigger the release of cortisol, a hormone associated with increased abdominal fat.Insulin resistance: Estrogen can help maintain insulin sensitivity , which helps us avoid insulin resistance. When estrogen levels decline, we are at higher risk for insulin resistance, a condition that makes it harder to regulate blood sugar and can increase the likelihood of weight gain.Genetic and biological factors: Some women may be genetically predisposed to gain weight during this phase, while others may not experience significant changes.Perimenopause weight gain therefore arises from a variety of factors—some hormonal, some due to aging, others due to lifestyle and genetic factors.
Why is it so hard to lose weight during perimenopause? It’s hard to lose weight during perimenopause because your hormones, aging body, and lifestyle factors are working against weight loss.
Perimenopause leads to a decrease in estrogen, which is associated with metabolism deficiency . Aging is also related to a decrease in muscle mass, which also negatively impacts our metabolism.When our metabolism decreases, we burn fewer calories overall, making it harder to lose weight, even if we’re eating just as much as we were before.
Estrogen also helps manage our hunger signals , like when our body tells us when we’re full. When estrogen decreases, we don’t get those same signals, and are more likely to eat in excess. Lifestyle factors work similarly—if we don’t get enough sleep, for example, we’re more likely to choose less nutritious food options and eat in excess .
How long does perimenopause weight gain last? Perimenopause weight gain can last about as long as perimenopause does, which is about four to eight years, but can vary greatly from person to person.
Weight gain often starts in the early stages of menopause, and often becomes more pronounced as estrogen levels decline and hormones begin to fluctuate more as you reach menopause. However, some people may experience weight fluctuations for a shorter duration, while others may find it persists over a longer period. Some may also notice gradual changes, while others may experience more pronounced shifts.
Once menopause is reached, hormonal levels stabilize and perimenopause weight gain tends to plateau.
It can be frustrating not to know what to expect from perimenopause weight gain. Will your weight gain be more gradual or pronounced? Will it happen quickly or toward the end? Every person is unique, and their experience of this symptom is unique. While that can be challenging, it means that maintaining your health is a unique, personal journey.
Treatment for perimenopause weight gain Let’s get the important part out of the way: weight gain during perimenopause is not necessarily a negative thing. We’ve been taught that weight gain is always troublesome, but carrying a few extra pounds isn’t always bad—it’s natural for your body to change and fluctuate over time.
Perimenopause weight gain can be a problem, however, if it affects your overall health. For example, overweight and obese menopausal women are at a greater risk of cardiovascular complications and diseases, osteoporosis, and cancers. Weight gain can also exacerbate certain perimenopause symptoms, like bone-related issues such as joint pain .
So if you are looking to lose weight during perimenopause, what are your options?
Natural ways to lose weight during perimenopause There are a few ways to naturally lose weight during perimenopause, by changing various lifestyle factors:
Regular physical activity: Muscle mass often decreases with age, which can affect your metabolism during this transition period. Engaging in regular exercise, specifically strength training that builds muscle, can help counteract this effect and boost your metabolism. High-intensity training has also shown to reduce risk factors for type 2 diabetes and cardiovascular diseaseBalancing your diet: Adopting a balanced and nutritious diet of whole foods (vegetables, fruits, lean proteins, whole gains, and healthy facts) and limited processed foods, sugar, and saturated fats can help promote overall well-being.Stress management: Chronic stress, which often arises during perimenopause, can lead to hormonal changes that increase your appetite and cravings for less nutritious, higher-calorie foods. Managing stress and incorporating stress-reducing techniques such as yoga, meditation, deep breathing exercises, or hobbies can help manage cortisol levels and support weight control.Adequate sleep: Inadequate sleep—which happens often during perimenopause due to hot flashes and night sweats—can impact hormones that regulate hunger cues. Establishing a consistent sleep routine can help support overall health and weight management.Perimenopause weight gain supplements While it's important to focus on a well-balanced diet for overall health and managing perimenopause weight gain, some supplements may be considered to support specific nutritional needs during this transitional phase. It's crucial to consult with a healthcare professional before adding any supplements to your routine, as individual requirements can vary.
Here are some of the best supplements for perimenopause weight gain:
Calcium and vitamin D: Hormonal changes during perimenopause can impact bone density. Calcium and vitamin D supplements may be recommended to support bone health and reduce the risk of osteoporosis. Adequate calcium intake is essential for maintaining strong bones, and vitamin D aids in the absorption of calcium.Omega-3 fatty acids: Omega-3 fatty acids, found in fish oil supplements, may help manage inflammation and support heart health. As women age, maintaining cardiovascular health—especially when weight gain puts you at risk for cardiovascular problems—becomes increasingly important.B Vitamins: B vitamins, including B6 and B12, play a role in metabolism and energy production. As metabolism tends to slow down during perimenopause, B vitamin supplements may support energy levels. Probiotics: Gut health is increasingly recognized as important for overall well-being. Probiotic supplements can help maintain a healthy balance of gut bacteria, supporting digestion and potentially aiding in weight management. Probiotics are also found in fermented foods like yogurt and kefir.Hormone support supplements: Hormone-supportive supplements like phytoestrogens (found in soy products) or adaptogenic herbs, have been shown to play a role in weight loss. However, these should be approached with caution and under the guidance of a healthcare professional.Always remember that supplements should complement, not replace, a healthy diet. It's important to obtain most nutrients from a well-balanced and varied diet, and supplementation should be tailored to individual needs and health status. Regular monitoring by a healthcare provider can ensure that supplements are used safely and effectively.
Hormone replacement therapy (HRT) Because hormone fluctuations during perimenopause play a part in weight gain, hormone replacement therapy can help balance those hormone levels to help alleviate this symptom. HRT can help replace lost levels of estrogen and progesterone and promote hormonal balance. However, the decision to pursue HRT should always be made in consultation with a healthcare provider, weighing potential risks and benefits.
Overall, addressing perimenopause weight gain—if weight gain is affecting your overall health—can involve a combination of lifestyle adjustments, potential supplements, and hormonal considerations. By taking a comprehensive approach and making sustainable changes for your unique health, you can manage weight gain effectively and boost your overall well-being.
