5 Ways That Perimenopause and Menopause Can Derail Your New Year’s Resolutions

If your New Year’s resolutions are slipping, it’s tempting to blame yourself. But for many women in their 40s and 50s, the real issue isn’t effort – it’s hormones.

Perimenopause and menopause quietly change how your brain and body work. Sleep becomes fragile, energy dips, and motivation wavers. Healthy habits that once felt achievable suddenly feel much harder to sustain.

Here are 5 key reasons why it happens…

1. Hormonal Changes

During perimenopause and menopause, estrogen levels fluctuate and then fall. Estrogen affects far more than reproduction – it influences sleep, mood, appetite, pain perception, metabolism, and motivation.

As estrogen shifts, many women experience disrupted sleep, fatigue, brain fog, low mood, anxiety, joint aches, muscle stiffness, and food cravings. These symptoms quietly undermine your ability to eat well, exercise, and sustain healthy habits.

It’s not because you’re weak; your body is adapting to a major biological transition.

2. Sleep Deprivation

Sleep often unravels first. Hot flushes, night sweats, and palpitations can prevent you from getting deep, restorative sleep. Poor sleep makes everything harder: it increases hunger hormones, reduces impulse control, worsens mood, and drains motivation. You’re more likely to crave sugar, skip workouts, and
feel overwhelmed by small decisions.

All are signs of an exhausted nervous system signalling it needs support.

3. Altered Nutritional Needs

Many women are frustrated when the old “eat less, move more” advice doesn’t work. Falling estrogen is linked to increased abdominal fat, higher cholesterol, and insulin resistance, even if your eating hasn’t changed. Fatigue, joint pain and slower recovery make high-intensity workouts feel punishing rather than energising. Food and movement still matter, but they need to adapt. Realistic, sustainable nutrition and the right kind of regular movement are far more effective than restriction or pushing harder.

4. Low Energy Levels

When we’re tired it’s all too easy to reach for quick sugary snacks for an energy boost to get through the day. The problem is they send blood sugar soaring, then it crashes back down leaving us shaky, moody, wiped‑out and far less likely to exercise, even when we genuinely want to. Over time this cycle can add to weight gain and make movement feel harder than it needs to be.

A simple reset is to have a low‑GI carb snack about an hour before exercise, for a steadier energy supply instead of a rollercoaster. After a workout, consuming protein (and perhaps creatine) helps muscles recover and stay strong.

5. Increased Chronic Disease Risk

Besides the effects of symptoms, the silent changes of perimenopause and menopause are also starting to take hold:

– Bone loss accelerates, increasing the risk of osteoporosis, fractures and loss of independence;
– Heart disease risk increases. Cardiovascular disease is the equal highest killer of Australian women, along with…
– Dementia. Our dementia risk rises after menopause, but can be significantly reduced with lifestyle measures.

The power of small, sustainable changes

Menopause presents a powerful opportunity to prevent chronic disease and support healthy ageing. Research shows that small, sustainable lifestyle changes now – combined with appropriate menopause treatment – have a big impact on bone strength, heart health, and brain health.

It’s not about perfection. It’s about timely intervention, realistic habits, and the right medical support.

What’s the harm in doing nothing?
