If you’re a woman in midlife taking a GLP-1 medication, you are not alone.
Over the past few years, we’ve spoken with hundreds of women navigating this new chapter. For many, GLP-1 medications have been life-changing. They’ve helped quiet the constant noise around food, improved blood sugar balance, and made weight loss feel possible again.
But what we’re seeing — and what we care deeply about — is what happens after the appetite suppression begins.
Because eating less does not mean your body needs less support.
In fact, for women over 40, the opposite is often true. When calories drop quickly, your body still needs the nutrients that protect muscle, bone density, gut health, metabolism and skin vitality.
We believe this phase of life deserves education, empathy and joy — not restriction and depletion.
So if you are taking a GLP-1 medication, here are the key areas your body needs to stay strong, nourished and vibrant.
GLP-1 receptor agonists work by slowing gastric emptying, improving blood glucose control and reducing appetite signals in the brain (Drucker, 2024).
While this can support weight loss, it also means women often consume significantly fewer calories and nutrients.
Without thoughtful nutrition, this can lead to:
For women already navigating hormonal shifts in midlife, these risks matter.
Which is why we encourage women to approach GLP-1 medications not as a stand-alone solution, but as one tool within a broader support system.
One of the most common side effects women report with GLP-1 medications is digestive disruption.
Because food stays in the stomach longer, women can experience:
A healthy gut microbiome plays a critical role in metabolism, immune health, hormone balance and nutrient absorption (Zmora et al., 2019).
This is why gut support becomes even more important when appetite decreases.
Sparkle was designed as a daily gut health ritual to help support digestion, microbiome balance and regularity. It combines prebiotic fibres, probiotics and plant-based antioxidants to nourish beneficial bacteria and support digestive comfort.
When your gut is supported, everything from energy to mood and metabolic health becomes easier to manage.
And when you’re eating less, your body needs to absorb every nutrient it can.
When appetite decreases, the goal is no longer simply eating less.
The goal becomes eating better.
Women on GLP-1 medications need to prioritise nutrient-dense foods — foods rich in vitamins, minerals, fibre and protein relative to their calorie content (Drewnowski, 2005).
Think:
But we also recognise the reality many women face: some days the appetite simply isn’t there, or the optimum diet is at the bottom of your to-do list.
This is where Flourish supports daily nourishment.
Flourish is our nutrient-dense greens blend, designed to help support energy, immune health, digestion and vitality with organic greens, antioxidants and adaptogens.
It’s not about replacing food.
It’s about helping your body receive the nutrients it still needs, even when intake is smaller.
This is one of the most important conversations we can have about GLP-1 medications.
When weight loss occurs rapidly, the body can lose lean muscle mass along with fat.
For women over 40, muscle is not just about strength or aesthetics. It supports:
Research shows maintaining protein intake and resistance exercise is essential to preserving lean mass during weight loss (Jastreboff et al., 2022).
At Eir, we created Fuel to support women’s strength, cognitive health and recovery.
Fuel contains 100% pure creatine monohydrate — one of the most researched supplements for improving strength, muscle mass and cellular energy.
For women in midlife, creatine can also support brain energy and cognitive clarity.
Weight loss should never come at the cost of strength.
The goal is not simply a smaller body — it’s a stronger one.
Bone health becomes increasingly important for women as oestrogen levels decline through perimenopause and menopause.
Oestrogen plays a protective role in maintaining bone density, and when levels drop, bone loss can accelerate (Eastell et al., 2016).
When weight loss occurs quickly, additional stress can be placed on bone health.
Supporting bone density means focusing on:
This is where Revival plays an important role.
Revival contains clinically studied collagen peptides designed to support bone density, joint health and skin elasticity.
For many women, it becomes part of a daily ritual that supports both structural health and visible vitality.
Because feeling strong and confident in midlife is about more than numbers on a scale.
Rapid weight loss can sometimes affect skin elasticity and hydration.
Skin relies on collagen, protein intake and antioxidants to maintain firmness and resilience (Proksch et al., 2014).
When calories decrease significantly, collagen production and skin hydration may decline.
Supporting skin from within becomes important.
Revival’s collagen peptides are specifically selected to support:
For many women, this support helps the skin adapt more gracefully to changes in body composition.
Your transformation should feel nourishing, not depleting.
6. Weight Management Support
GLP-1 medications can be powerful tools for regulating appetite and blood sugar, but sustainable metabolic health still relies on multiple factors including nutrition, movement and lifestyle habits.
Trimmed was designed to support women pursuing healthy weight management and body composition goals.
With clinically researched ingredients, Trimmed works alongside lifestyle choices to support metabolic balance and abdominal weight reduction.
When used alongside nourishing foods, strength training and supportive supplementation, women can create a more balanced and sustainable approach to weight management.
If there is one message we want women to hear, it is this:
Midlife is not a time to deprive your body.
It is a time to support it wisely.
GLP-1 medications may help reduce appetite, but your body still deserves:
At Eir Women, we believe the second half of life can be vibrant, strong and full of possibility.
And that happens when women are supported with knowledge, community and products designed for their changing bodies.
Do GLP-1 medications cause muscle loss?
GLP-1 medications can lead to muscle loss if protein intake and resistance training are not prioritised during weight loss. Maintaining adequate protein and supporting muscle through strength training can help preserve lean mass.
Why do GLP-1 medications cause digestive issues?
GLP-1 medications slow gastric emptying, meaning food remains in the stomach longer. This can lead to symptoms such as bloating, constipation or nausea in some people.
What nutrients should women focus on while taking GLP-1 medications?
Women should prioritise protein, fibre, vitamins, minerals, creatine and collagen-supporting nutrients to maintain muscle, gut health, bone density and skin vitality.
Are supplements helpful when taking GLP-1 medications?
Targeted supplements can help support areas commonly affected by reduced food intake, including gut health, muscle maintenance, skin health and nutrient density.
