5 Small Habits That Make The Biggest Difference To Your Health After 40

5 Small Habits That Make The Biggest Difference To Your Health After 40

If you've noticed that the things that used to work for your body in your 30s no longer seem to have the same effect, you're not imagining it. After 40, your body's needs shift in meaningful ways, and the habits that genuinely support your health at this stage go well beyond the standard advice of drinking more water and getting to bed earlier.

The good news is that the most impactful changes are often the simplest. They don't require an overhaul of your life, just a deeper understanding of what your body is asking for, and the willingness to show up for it consistently.

Here are our top five evidence-informed habits that can make a profound difference to how us women can feel, function, and thrive after 40:


1. Eat More Protein Than You Think You Need

One of the most common, and most consequential, nutritional gaps in women over 40 is inadequate protein intake. Most women are eating far less than their body actually needs, and the effects can accumulate quietly: loss of lean muscle, a slower metabolism, persistent cravings, low energy, and fatigue that no amount of rest seems to resolve.

Here's what the research tells us. After 40, your body becomes less efficient at using the protein you consume, a phenomenon known as anabolic resistance. This means your requirements actually increase with age, not decrease. Studies consistently show that an intake of 1.0–1.2g of protein per kilogram of body weight per day is significantly more effective for preserving muscle mass, strength, and physical function in older adults than the standard dietary recommendation of 0.8g.

Lean muscle is not just about appearance or fitness. It is your metabolic engine. It supports bone density, insulin sensitivity, hormonal health, and long-term physical independence. Protecting and maintaining it through adequate protein intake is one of the most important nutritional investments a woman can make after 40.

What to do: Aim to include a quality protein source at every meal: organic eggs, legumes, oily fish, quality meat, Greek yoghurt, or a clean protein supplement, and don't be afraid to make it the foundation of your plate rather than an afterthought.

Nourish your body with intention: The Healthy Chef Protein range features clean, natural protein options that blends effortlessly into smoothies, oats, or baked goods, making it easier to consistently meet your daily protein needs.

2. Support Your Gut Microbiome Every Single Day

Your gut is doing far more than digesting your food. It is home to trillions of microorganisms that collectively influence your immune system, hormonal balance, skin health, mood, cognitive clarity, and your body's ability to manage inflammation. The gut-brain axis, the bidirectional communication network connecting your digestive system to your central nervous system, means that the state of your gut has a direct and measurable impact on how you feel, think, and function.

Perhaps the most striking example of this connection is serotonin. Approximately 90% of the body's serotonin, the neurotransmitter most closely associated with mood, emotional wellbeing, and sleep, is produced in the gut, not the brain. When gut bacteria are disrupted or imbalanced, serotonin production can be affected, contributing to low mood, anxiety, poor sleep, and a general sense of feeling off.

As we get older, the natural diversity of our gut microbiome begins to decline. This makes actively nourishing it more important than ever. Prioritising fermented foods like yoghurt, kefir, sauerkraut, and kimchi alongside prebiotic-rich vegetables such as garlic, leeks, asparagus, and oats helps create the conditions for a thriving microbiome. Targeted supplementation can also offer meaningful additional support, particularly during times of dietary imbalance, stress, or change.

What to do: Focus on variety and consistency. A gut that is fed a diverse range of whole plant foods and quality probiotics is a gut that works in your favour, every single day.

Support your gut from within: Healthy Chef Probiotic + Prebiotic combines both elements (+ more!) in one clean, gentle daily formula, designed to restore and maintain inner balance and support comfortable, regular digestion as part of your wellness routine.

3. Invest in Your Nervous System — Before It Reaches Breaking Point

Most of us have been taught to manage stress after the fact - to take a bath when we're overwhelmed, to breathe when we're anxious. But there is a more proactive and ultimately more effective approach: tending to your nervous system as a daily practice, before stress has the chance to accumulate.

Chronic low-grade stress, the kind that hums quietly in the background of a full and demanding life, has a profound impact on our bodies as we get older. Elevated cortisol over time can accelerate biological ageing, disrupt hormonal balance, deplete key nutrients including magnesium and B vitamins, promote inflammation, and impair the body's ability to recover and repair. Research has found that when cortisol levels remain chronically elevated, the downstream effects include muscle loss, bone density reduction, cognitive decline, and increased risk of cardiovascular disease.

The nervous system is the foundation upon which every other system in the body operates. When it is dysregulated, everything else is harder: sleep, digestion, hormonal balance, immune function, and even the ability to absorb and utilise the nutrients you eat.

What to do: Build daily nervous system practices into your routine before stress demands them. Breath work, gentle movement in nature, consistent meal timing, reducing stimulant dependency, and increasing magnesium-rich foods (dark leafy greens, seeds, cacao, and legumes) are all meaningful, cumulative investments in your body's resilience.

To help maintain your nervous system health and support a healthy stress response in the body, add Healthy Chef Magnesium+* into your routine. Our refreshing lemon-lime flavoured blend combines 4 types of magnesium with vitamin C and zinc enhanced efficacy and absorbency.

4. Prioritise Collagen, Before You Notice Its Absence

Collagen is the most abundant structural protein in the human body. It is the scaffolding behind your skin's firmness and elasticity, the cushioning in your joints, the integrity of your bones, and the condition of your hair and nails. And from your mid-30s onwards, your body produces progressively less of it, at a rate of approximately 1–1.5% per year.

As we get older, the effects of this decline can begin to manifest visibly and physically: changes in skin texture and elasticity, increased joint stiffness or discomfort, slower recovery after exercise, and a general loss of the structural resilience that the body had in earlier decades. For women, this process is further accelerated during perimenopause and menopause as oestrogen, which plays a key role in stimulating collagen synthesis, begins to decline.

The mistake most women make is waiting until the signs are noticeable before acting. Collagen supplementation is most effective when it is consistent and preventative — supporting the body's ability to synthesise and maintain collagen before the deficit becomes significant.

It is worth being clear: collagen is not a beauty trend. It is a foundational structural protein that your body genuinely depends on for physical integrity, comfort, and function, at every age.

What to do: Make collagen supplementation a simple, non-negotiable part of your daily routine. Pair it with vitamin C-rich foods, which are essential for collagen synthesis, and reduce factors that accelerate collagen breakdown: excess sugar, smoking, UV exposure, and chronic stress.

Nourish your structure from within. The Healthy Chef Collagen range features two 100% pure collagen blends in the form of Marine and Grass Fed Collagen. Both blends feature unflavoured hydrolysed collagen powder that dissolves effortlessly into your morning coffee, smoothie, or warm water, creating a simple daily habit that supports your skin, joints, and overall structural health from the inside out.

5. Start Eating With Your Hormones in Mind

After 40, the hormonal landscape shifts significantly. Oestrogen and progesterone levels begin to fluctuate and eventually decline during perimenopause and menopause, and the effects ripple across nearly every system in the body, influencing weight, energy, mood, sleep quality, skin, bone density, and cardiovascular health.

What is not widely understood is that the food you eat has a direct and meaningful influence on how your hormones behave. Every meal either supports or undermines hormonal balance depending on its composition and quality.

Reducing ultra-processed foods, refined sugars and alcohol, which can promote inflammation and can disrupt hormonal signalling, is a foundational starting point. From there, increasing specific foods that actively support hormonal balance makes a compounding difference.

Foods that support hormonal health after 40:

  • Cruciferous vegetables (broccoli, kale, cauliflower, Brussels sprouts)
  • Flaxseed and legumes
  • Healthy fats (avocado, extra virgin olive oil, oily fish, nuts and seeds)
  • High-fibre wholefoods
  • Magnesium-rich foods

Food is information for your hormones. Every meal you eat sends a signal to your endocrine system, and over time, those signals shape how you feel in your body, every single day!

What to do: Begin by auditing your plate for what is missing rather than what to remove. Most women find that adding more of the right foods naturally crowds out the less supportive ones, without requiring rigid restriction.


Your Health After 40 Is Not About Doing More

It is about understanding your body more deeply, and nourishing it with the right foundations, consistently, and with intention.

The five habits above are not quick fixes. They are the kind of quiet, cumulative investments that compound over months and years into genuine vitality, resilience, and physical confidence, at every age and stage.

Start where you are. Choose one habit to anchor in this week. Then build from there.
