Many women approaching mid-life feel frustrated by unexpected weight gain despite maintaining healthy habits.
They often describe eating well, exercising regularly and maintaining routines that previously worked for them.
However, perimenopause introduces several physiological changes that can influence metabolism. Let’s take a look at a few.
Estrogen plays a role in fat distribution and insulin sensitivity. As estrogen (and progesterone) levels fluctuate, fat storage patterns may shift and blood sugar regulation may become less stable.
Sleep disruption, which is extremely common during perimenopause, also affects cortisol, appetite hormones and metabolic signalling.
When sleep quality declines, the body produces more ghrelin (which stimulates hunger) and less leptin (which signals fullness). This hormonal shift can make appetite regulation more challenging.
Stress hormones can also increase during periods of sleep disruption and hormonal fluctuation, which may further contribute to abdominal fat accumulation.
Understanding these physiological drivers behind midlife weight gain can help guide strategies that support metabolic stability during perimenopause.
