Women, Weight Loss and Menopause
Weight loss for women after 40 is shaped by hormones, stress, control, and the structure of everyday life.
Hi, this is Shan. I run Xandro Lab, a science-first longevity brand working on problems of aging, performance, and recovery, using supplements and a lot more beyond that.
I have an important update - this blog is now completely free for everyone. No more paid subscriptions.
Last week, I asked our community a simple question:
What’s the one health goal you need help with this year?
The responses were overwhelming and came almost entirely from women in their 40s and 50s:
“I want to lose weight, but nothing works anymore”
“I’m in perimenopause and my body won’t respond”
“I know what to do, but I can’t make it stick”
This hit me hard. So I spent time talking to women in this phase, consulting with practitioners, and combining that with what I’ve learned over years of working in this space.
What follows is my honest attempt to address what’s actually happening and what genuinely helps.
Why This Is the Hardest Phase
If I had to rank which demographic struggles most with weight loss, women aged 40-55 would be at the top.
Not because they don’t know what to do. Most women I know in this phase are extremely informed. They’ve tried diets, gyms, trainers, apps, supplements—everything. Yet the weight either won’t move, or it comes right back.
Two things collide simultaneously:
1. Biology Changes
Estrogen and progesterone fluctuate wildly during perimenopause
Insulin sensitivity drops (your body handles sugar less efficiently)
Sleep becomes fragile and light
Stress hormones stay elevated longer
Fat gravitates toward your midsection
Muscle naturally begins declining without intervention
The rules your body operated under in your 30s no longer apply.
2. Life Gets Heavier
For most women in this age group, life isn’t something they fully control anymore:
Teenagers who need you
Aging parents requiring care
Households to manage
Demanding careers
A constant mental and emotional load that doesn’t show up on any calendar but drains energy daily
A personal contrast: I live alone. No kids. No family living with me. I control my food, sleep, training schedule, and social calendar. That level of control makes health changes far easier than we admit.
Most women in their 40s and 50s don’t have that luxury. When hormonal chaos hits on top of life chaos, weight loss becomes genuinely difficult—not impossible, but far more complex than any Instagram fitness plan suggests.
What Actually Works: Build Muscle First
The single biggest shift needed is moving away from “cardio for weight loss” thinking. Walking is great. Cardio is fine. But what really matters now is muscle.
Here’s why: Muscle is metabolic tissue. More muscle means:
Higher resting metabolism (though the effect is modest—about 13 calories per kilogram per day)
Better insulin sensitivity and blood sugar control
Stronger bones and joints as you age
More independence in later years
What this looks like:
Strength training 2-3x per week
Basic movements: squats, lunges, presses, rows, deadlifts
Start with bodyweight, progress to dumbbells or resistance bands
You don’t need a gym to begin (YouTube has quality tutorials. Just be careful and don’t hurt yourself)
Making it sustainable:
Group classes remove decision fatigue and create accountability. In Singapore, many classes now specifically off classes for the 40-50+ demographic.
Personal trainers (even for 8-12 weeks) can eliminate the fear of doing things wrong. If that’s not affordable, ask someone in your circle who trains—you’d be surprised how many people will help if you simply ask
Structure over motivation: Your training sessions must live in your calendar like meetings. You cannot rely on motivation when life is this full.
Get Protein Right
Most Asian diets are carb-heavy: rice, noodles, bread, convenient snacks. Meanwhile, protein—the nutrient that preserves muscle, stabilizes blood sugar, and keeps you full— gets neglected.
The simple shift: Make protein the foundation of every meal.
Eggs, fish, chicken, tofu, tempeh, Greek yogurt, cottage cheese, lentils, beans
If non-vegetarian: Focus on lean sources (chicken, fish, lean beef). Avoid fatty cuts and processed meats as your default
If vegetarian/vegan: This gets trickier. Protein powder becomes extremely useful. 1-2 shakes daily can simplify everything. Consider adding creatine (safe, well-studied, helps preserve muscle)
Build awareness: Track your food for 2-3 weeks. You’ll learn where your calories actually come from and what you can adjust without suffering.
The goal isn’t perfection. It’s building a pattern you can maintain for years. Extreme diets rarely work long-term in this phase of life. Sustainable changes, repeated consistently, do.
The Hidden Layer: Hormones, Gut, Sleep, Stress
Even with good movement and nutrition, these factors quietly determine whether your efforts actually translate to results.
Hormones
During perimenopause, estrogen and progesterone become unpredictable. This affects:
How your body stores fat
Water retention and bloating
Cravings and mood stability
Insulin sensitivity (making blood sugar harder to control)
What helps: Some women find liver support useful—compounds like DIM (diindolylmethane) and calcium-d-glucarate may help process hormones more efficiently, though research is still emerging.
(Disclaimer: Always discuss hormone-related interventions with your doctor)
Gut Health
Your microbiome influences metabolism, inflammation, and how efficiently your body uses calories.
Simple tools:
Increase fiber through vegetables, seeds, and whole foods (most people eat far too little)
Quality probiotics with specific, well-researched strains can help, though results vary person to person
Sleep and Stress
These might be the biggest silent saboteurs:
Poor sleep worsens insulin resistance and increases next-day hunger
Chronic stress keeps cortisol elevated, signaling your body to store fat
Together, they create a vicious cycle that’s nearly impossible to break if ignored
This is foundational work. No supplement compensates for chronically poor sleep or unmanaged stress.
(Disclosure: At Xandro, we’ve developed supplements specifically to support this phase—LXP for metabolic health and weight management, Protocol X for overall metabolic support. They’re tools that work best when foundations are already in place, not replacements for them.)
The Timeline No One Tells You
In your 20s or early 30s, a few weeks of effort could move the scale. That timeline no longer applies.
For most women in their 40s-50s, meaningful, stable change takes 6-7 months of consistent effort. You’ll notice energy improving first. Then sleep. Clothes fitting differently. Strength increasing. The scale often comes last.
This is where most people quit—after 3-4 weeks with minimal change, assuming their body is broken. It’s just responding at a different pace. Hormones take time to stabilize. Muscle takes time to build. Gut bacteria take time to shift. Stress patterns take time to calm.
Move beyond the scale: For women, body fat percentage will naturally be higher than men. Chasing extremely low numbers isn’t realistic or healthy.
Better indicators:
Strength levels
Body composition (how clothes fit)
Energy throughout the day
Blood markers: fasting insulin, HbA1c (blood sugar control), lipid panel, CRP (inflammation), vitamin D, ferritin (iron), thyroid markers (TSH, free T3, free T4), hormone levels (estradiol, progesterone, FSH)
These tell a far more accurate story than your bathroom scale.
Why This Really Matters: A Personal Note
My mother is in her 60s. She has knee issues and struggles with movement. She tries to eat less, but it’s extremely difficult. She never learned about protein and strength the way we understand it now.
Last week, my dad fractured his knee—his second leg fracture. He’s in his 70s. This happened from a simple fall on uneven ground. He never trained his muscles when younger. Now he’s terrified of falling, and that fear makes movement harder and riskier.
I share this because it clarified something for me: Strength offers independence. It’s about how well you get to live in your later years.
This is also why compassion matters so much in this phase. Many women are being brutally hard on themselves for something deeply influenced by biology, life structure, and accumulated stress.
That doesn’t mean giving up. It means approaching the journey with patience and respect for what your body is going through.
The Bottom Line
If you’re in your 40s or 50s and struggling with weight, your body is asking for a different kind of care now:
Prioritize strength training over cardio alone
Make protein central to every meal
Address sleep, stress, and gut health—they’re not optional
Think in months, not weeks
Track meaningful markers beyond the scale
Be kind to yourself—this phase is genuinely hard
With the right approach—and realistic expectations—things can improve.
It just needs time.
See you next Sunday.
