Leading metabolic therapist:
The real reason why women over 40 barely lose weight any more, and how you can “reactivate” your body at home.
If you notice that losing weight gets harder every year, even though you move daily, watch what you eat and try everything, you should read this report before you do anything else.
Hello, my name is Dr. Mara Keller.
I have been a metabolic therapist and specialist in metabolic rehabilitation for over 12 years.
I work daily with women who barely lose weight despite all their effort. Many of them count steps, eat consciously, train regularly and do everything they are told.
Their bodies still hardly change.
Over the past years I have worked with more than 1,400 patients. Young mothers, women under heavy professional pressure, women in menopause. And again and again I saw the same pattern.
They do everything they are supposed to do, but their body barely burns any energy.
It was not that these women did too little, it was that their bodies used almost no energy in everyday life. Not because they moved too little or ate badly.
The problem lies much deeper...
In my research I found that it comes down to one particular muscle group that was almost completely inactive: the deep, stabilizing muscles that normally work quietly and invisibly all day.
These muscles handle small automatic movements, posture corrections, balance, and above all the pump function for lymph and circulation.
In short: they are the underrated engine of daily calorie burn.
After years of hearing more and more women say the same sentences:
- “I walk 10,000 steps every day, but nothing happens!”
- “Every small change used to work immediately. Now nothing does...”
- “I eat less than before and still do not lose weight. How can that be?”
...it became clear to me that something did not add up.
These women were not lazy. They were not comfortable. They followed the recommendations, they moved, they watched their meals, and still the scale went up year after year.
So I began to observe more closely, to measure and to compare cases. And the more data I collected, the clearer a pattern became that most people never get to see.
Shocking truth: the real cause of the “weight loss” problem
But why is this muscle group suddenly inactive?
Many women, especially from their mid thirties, forties and fifties, gradually lose these deep muscle groups because stress, hours of sitting, hormonal changes and exhaustion mean the body activates them less and less. Until they practically “switch off”.
Once that happens, the basal metabolic rate drops automatically, the metabolism runs slower, and the body burns far less energy even during movement.
Important: this is a natural and hormonal process that happens in 97% of all women at this age. Often there is nothing you could have done about it.
At that point I understood: the problem was not that my patients did too little, but that their bodies burned too little. And that changed everything.
Why does the body burn fewer calories even though you move?
To understand why so many women do not lose weight despite the effort, we have to look at how the body burns calories in everyday life.
Because most daily calories do not come from sport or deliberate exercise...
...they come from NEAT.
NEAT = “Non Exercise Activity Thermogenesis”, meaning:
→ the energy the body burns through small, automatic movements.
For example: posture corrections, stabilization, micro tension, balance.
And here is the important point: the deep muscles are mainly responsible for NEAT.
These deep muscles:
- stabilize joints
- hold the body upright
- balance out movements
...and work in the background with every step, every movement and every posture.
So the deep muscles account for more than 20% of total calorie expenditure.
Study 1 (English) on NEAT: “Non-Exercise Activity Thermogenesis (NEAT)” — Author: James A. Levine. Date: July 1, 2004.
What happens when the deep muscles keep “sleeping”...
When the deep muscle groups barely work any more, which is the case for most women over 40, the whole metabolism slowly falls out of balance.
In the first years it looks harmless:
- weight goes up more easily
- clothes fit tighter
- simple everyday movements feel “heavy”
...and the husband who says: “Honey, did you eat too much cake again?”
That has happened to all of us. But that is only the beginning of the story. Something far more dangerous happens in the background:
- Energy expenditure drops further every month
- The body stores more fat
- Hormones fall out of rhythm
...and suddenly the body barely responds to diets, steps or sport.
That is exactly what all my patients describe daily: “I try everything, but my body does nothing!”
And if you change nothing at this point, the state will not stay stable, it gets worse automatically. Day by day. Week by week. Year by year.
⚠️ WARNING: what happens if the core muscles keep switching off?
Sharply increased risk of lipedema like changes
(pressure pain, massive water retention, symmetrical leg enlargement)
Obesity despite normal eating
(the body barely burns energy any more)
Chronically slowed lymph flow
→ hardening in the tissue, constant swelling, pain
Accelerated skin aging and irreversible connective tissue damage
(cellulite, sagging, “my legs do not feel like mine any more”)
Increased risk of circulatory and metabolic problems
(blood sugar imbalances, inflammation, high blood pressure)
Emotional collapse
→ shame, withdrawal, loss of joy and identity
How the deep muscles should actually work
In a young, fresh and healthy body the deep muscles work along permanently in the background. They do not only stabilize, they keep the metabolism active, even while walking, standing or going about your day.
When these deep lying muscles work properly, daily calorie burn rises automatically, microcirculation runs better, and the tissue is continuously supplied, relieved and activated.
In theory exactly that should happen every day, to drive fat mobilization and energy expenditure.
When this process is active, the body responds much more easily to weight loss.
A patient recently came to me and asked me: “But Dr. Keller, I am not 20 any more, I am 52. You said yourself that this is a natural process.”
It is true, none of us are 20 any more... but you can definitely do something about it, the only question is what.
And this is exactly where most common solutions fail.
Before I had my breakthrough, I really tried everything with my patients: more steps, diets, fitness programs, creams, massage rollers, detox cures, and yes, even surgery.
And every time we saw the same pattern: short term mini successes, then a standstill.
And now I know that this is completely logical.
👉 All these methods work only on the surface, not where most of the calorie burn actually happens.
Let me explain with a few examples:
1.Diets
reduce calories, but often slow the metabolism down.
2.Exercise
helps, but does not automatically activate the deep muscle groups.
3.Creams and massages
feel good, but change nothing about the metabolic process.
4.Surgery
such as liposuction changes volume, but never metabolic activity or daily energy expenditure.
5.Lymphatic drainage
relieves briefly, but without active deep muscles the congestion always returns.
And all of that is quite apart from the costs these things cause every month.
The actual problem, which you and I should now both know, is the deep muscles and microcirculation (NEAT), which are barely active in most women.
To lose weight sustainably, exactly the part that controls basal metabolism, fat mobilization and daily burn has to be reactivated.
And unlike all the other “common solutions”, mine starts exactly there.
The only method that activates hidden muscle groups and makes losing weight possible again
Let us be honest: nobody does special deep muscle exercises every day. Nobody keeps up hard training plans or diets forever. And nobody has the time or desire to use massages, creams or devices for 20 minutes every evening.
That is why I looked for a solution that works automatically. Something my patients can use alongside their normal day, while walking, sitting, shopping, working, exactly where the deep muscles should be activated.
And this is exactly where the CelluFlex™ 3D compression leggings come in, to reactivate your deep muscles and the muscle groups that control your basal metabolism and your everyday calorie burn.
Introducing:
The COREEX CelluFlex 3D compression leggings
Thanks to the integrated kinesiology bands, every movement creates a gentle, barely noticeable micro resistance.
This resistance makes your deep muscles work harder automatically, while walking, standing, cooking, working or simply going about your day.
Your body works in “active mode” again instead of being stuck in energy saving mode, and burns up to 3 times more calories.
You do not have to do anything extra.
At the same time the medical compression zones stimulate circulation and microcirculation.
The integrated 3D micro massage structure also means the tissue is lightly stimulated with every movement, similar to a constant, gentle massage.
This micro stimulation improves the transport of fluids, increases nutrient supply in the tissue and makes the metabolism more responsive overall.
And that is exactly why your NEAT value (your everyday fat burning) rises again.
When the deep muscles sleep, NEAT often drops sharply. You burn less even though you move.
Through the combination of micro resistance, compression and 3D micro massage, your muscles work continuously again, so your body burns noticeably more calories across the day, without training or extra strain.
So the leggings do what would theoretically be necessary: they activate your tissue, your metabolism and your deep muscles, automatically, without you having to train or change your diet.
The CelluFlex™ takes over the work your body can no longer do alone. It gives you the daily, gentle impulse that lifts your calorie burn noticeably.
The result for you:
- Your metabolism runs again
- Your muscles burn more calories in everyday life
- Your circulation and microcirculation improve day by day
- Your NEAT rises noticeably, so your body works for you again instead of against you
And you only have to do one thing: put them on in the morning.
At the time I write this report, more than 10,000 women in Switzerland, Germany and Austria already wear the CelluFlex™ 3D compression leggings daily.
And the feedback from my own patients and from real buyer reviews is clear: more energy, less heaviness, more active muscles, a noticeably flatter stomach, slimmer legs, and less weight on the scale.
The CelluFlex™ is now the fastest growing functional legging in the German speaking market, with over 3,500 verified five star reviews across different platforms.
Women keep reporting:
- “I am finally making progress again.”
- “I am losing weight again without doing more.”
- “I feel so much lighter, already after the first few days.”
- “For the first time everything makes sense.”
And the most important part: most say not only that they see results, but that they finally feel motivated again, because their body is working with them.

I never normally write reviews, but after years of frustration I feel understood for the first time. I am 52, have two children, and no matter what I tried, diets, intermittent fasting, twelve thousand steps, massage rollers, creams, detox cures, even a consultation for liposuction, nothing worked long term. I would lose one or two kilos briefly and then came the standstill, the frustration and eventually resignation.
When my family doctor recommended Dr. Mara Keller, I was already at the end inside, but her explanation made real sense for the first time. My discipline and my diet were not the problem, the problem was that my deep muscles had been asleep for years and my basal metabolism was practically on the floor.
When she recommended the CelluFlex leggings I was skeptical at first, but I tried them and I am so grateful. In the first two weeks my legs got lighter and my ankles less swollen. In weeks three and four my stomach got visibly flatter and I lost a little over a kilo without changing anything. In weeks five to eight the scale already showed almost four kilos less, my waist got more defined and I felt full of energy again. After ten weeks it was a little over five kilos and I could finally wear dresses again without feeling uncomfortable. My partner even said I looked younger.
For me the CelluFlex is not a miracle cure, but it activates exactly the part of the body that had been switched off for years. I now recommend it to all my friends who feel their body is not working with them any more. If you recognize yourself in this, do not give up. It is not your fault, you just have to understand what is happening in your body. For me the CelluFlex was the first solution that really makes sense and actually works.

I stumbled across the article and recognized myself completely, so I simply ordered the leggings. I had already tried so much and was honestly quite frustrated. I then wore them every day, mostly from morning to evening, just normally in everyday life.
In the first week I only noticed that my legs got lighter and that I was not so exhausted in the evening. After about two to three weeks my jeans fit looser and my stomach looked more defined. I lost almost three kilos without dieting and for me that is a huge success, because otherwise I did not respond at all any more.
What I did not like was that they get a bit warm on very hot days, but that passes quickly. Ordering went smoothly and support answered very quickly when I was unsure about the size. For the result I find the price more than fair and I would definitely buy them again.

These leggings have helped thousands of people solve their “weight loss problem”.
And I am sure of it. The leggings will help you too.
Just imagine...
...you wake up in the morning and finally feel light, full of energy and comfortable in your body.
...you look in the mirror and see real changes day by day.
...you can enjoy your life, get compliments every day, closeness and real self confidence.
With the CelluFlex 3D compression leggings from COREEX all of that is possible.
I mean, do you have anything to lose? You simply put them on and live your day exactly as before, and you will feel the change.
That was all a bit much... I understand, believe me. You probably have several questions now and I will try to answer the most common ones.
COREEX CelluFlex™ - #1 Anti-Cellulite Leggings
QUESTION 1:
Are the results guaranteed?
That is always the first question everyone asks me. I know exactly what it is like to be desperate and to have spent a lot of money on supposed solutions that did nothing.
From hundreds of patient cases we know: as soon as the deep muscles are activated every day, everyday calorie burn rises noticeably, microcirculation improves and the body finally responds to weight loss again.
Of course, if you only wear the 3D leggings once a week and barely move, they will not work miracles.
INFO: if you really want to lose weight and you are serious about it.
Even ONE single day without the CelluFlex™ can set your progress back by up to 80%.
And that has a simple reason. Activating the deep muscles only works while you wear the leggings. As soon as you take them off, your body falls straight back into “energy saving mode”.
That means your fat burning drops again immediately, microcirculation is no longer stimulated and the deep muscles “fall asleep” again. Every interruption breaks the effect and the body starts over.
Many women only had one pair at first, and wondered why results came more slowly. Only when they got a second pair to alternate did the breakthrough come:
✔ no day off any more
✔ no interruption of the effect
✔ noticeably faster results
✔ constant activation instead of stop and go
If you really take your result seriously, do not leave your progress in the laundry every other day, get 2 pairs right away!
How do I get the 3D compression leggings as fast as possible?
The CelluFlex™ is not available in stores, not on Amazon and not from third party sellers.
It is sold exclusively on the official manufacturer website, so that every pair is checked, certified and genuine.
Demand has risen extremely in recent weeks. Many of my patients order for friends or for their daughters at the same time, so our stock drops rapidly again and again.
We could be sold out tomorrow... or maybe even today.
And this is exactly where the problem starts: once our warehouse is empty, it can take several weeks or sometimes even months before we can produce more.
Making the special 3D compression structure and the integrated kinesiology bands is very complex and we produce in small batches to guarantee the quality of every single pair.
If you are reading this article now, it means we currently still have some leggings in stock. But I cannot say how long that will stay the case.
Demand has risen extremely in recent days. Many women order 2 to 3 pairs straight away so they can alternate daily.
So if you seriously want to activate your metabolism and lose weight more easily again, you should not close this page before you have secured your size.

I know exactly what happens if you change nothing today. I have seen it in so many women, and it never ends well.
You will keep trying things that only work on the surface. Mini successes, then a standstill. More frustration, more weight, less energy. And while you hope “that it will get better at some point”, your body keeps working against you.
I am not saying this to frighten you, I am saying it because it is the truth. If you change nothing now, it will not get better. It gets worse automatically.
The decision is yours. Do you carry on as before? Or do you finally give your body the support it really needs?
And do not forget one thing:
This is not only about you.
It is about your family, who worry when you can move less and less. It is about your children or grandchildren, who need you, not a version of you that is constantly exhausted. It is about your partner, who at some point wonders where the radiant woman he once knew has gone.
You owe it to yourself and to the people who love you to take this step.
You can take back control. You can feel light again, be active and enjoy your life. Many women before you have done it, and you can too. All you need is a first step and the right support.
