Weight Struggles and Your Hormones

Why your body shape changes with perimenopause
The Hormonal Shift Behind Weight Gain
As you approach your late 30s and 40s, your body begins a natural transition known as perimenopause. A key player in this shift is estrogen, a hormone that regulates many bodily functions. During perimenopause, your estrogen levels start to fluctuate and generally decline, which can have a ripple effect on your metabolism and how your body stores fat.
This isn't just about eating more or exercising less; it's a physiological change. Estrogen plays a role in where your body distributes fat, and with its decline, many women notice fat starting to accumulate more around their abdomen rather than hips and thighs. This shift in fat storage is a common and often frustrating symptom of perimenopause, making it feel like your body is working against you.
Beyond the Scales Body Shape Changes
It's not always just the number on the scale that changes; your overall body shape can transform too. Even if your weight remains relatively stable, you might find your waistline expanding or clothes fitting differently around your middle. This abdominal fat accumulation is often referred to as 'menopause belly' and is directly linked to the changing hormone landscape. This shift isn't just cosmetic; increased fat around the middle is associated with higher health risks, including cardiovascular issues. Recognising these changes as part of the perimenopausal journey can help you understand what's happening and empower you to take proactive steps to support your health and well-being. It's about adjusting to your body's new needs.
Metabolism Muscle and Movement
Your metabolism, the process by which your body converts food into energy, also experiences a slowdown as you age. This natural deceleration, combined with hormonal changes, means your body may burn calories less efficiently than it once did. Maintaining muscle mass becomes more challenging in perimenopause, and muscle burns more calories at rest than fat does, further contributing to a slower metabolism.
Regular physical activity, particularly strength training, becomes even more crucial during this time. It helps to counter muscle loss, boost your metabolism, and manage fat distribution. Think of it as supporting your body through its changes, helping it to stay strong and healthy even when hormones are in flux. It’s about adapting your routine to meet your body's evolving requirements.
Nutritional Choices for Hormonal Health
What you eat can significantly impact how your body navigates the hormonal shifts of perimenopause. Focusing on a balanced diet rich in whole foods, lean proteins, and plenty of fruits and vegetables can help manage weight and support overall health. Reducing processed foods, refined sugars, and excessive alcohol intake can make a noticeable difference. Paying attention to portion sizes and being mindful of your eating habits can also be beneficial.
It's not about strict dieting but rather making sustainable choices that nourish your body and support hormonal balance. Consider seeking advice from a nutritionist or your GP to discuss personalised dietary approaches that can best support your perimenopausal journey.
