5 Scientific Reasons Why Americans Find Losing Weight So Hard After 40
Has that spare tire belly been growing day by day?
Maybe you’ve tried to work out and watch your diet, but they just don’t seem to be working.
And you might have started reminiscing the days of youth when you could eat anything you want without worrying about weight gain.
Guess what? 100 million Americans share the same sentiment as you.
Once you hit your 40s, your body begins to undergo age-related changes and they often get worse as time goes by.
These changes often cause continuous weight gain at an alarming rate if left unchecked.
To combat these changes, many people would consider going on strict diets and take up regular exercise plans; but because of these age-related changes, most of these diets and workouts don't seem to work.
Even the most active runners put on unwanted weight. In one study published in The International Journal of Obesity, researchers followed more than 12,000 runners and found that age-related weight gain occurs amongst even the most active individuals. 
And there are 5 scientific reasons why weight loss is becoming more challenging as you age.
1. Reduction In Muscle Mass
When you were young, your body naturally had more muscle. Muscle generally expends more energy than fats. So even when resting, your body burns calories.
As you pass 40 years of age, your body gradually loses its muscle mass. Scientists call this condition “age-related sarcopenia”. It’s an inevitable phenomenon that occurs as we age.
The Journal of Strength & Conditioning Research showed that you could lose as much as 40% of muscle by the time you reach 80 years old!
This is why you've probably noticed that you don’t have that Herculean strength anymore. You can’t burn off those stubborn fats even if you jogged for hours. Your body has less muscle mass. It simply can’t burn as much calories as it once did.
You will also have an increased proportion of fat compared to muscle; and when you have less muscle mass, your body starts to burn less calories, whether you're resting or working out.
However, this reduction in muscle mass is probably not your worst concern...
A study published in the Frontiers in Physiology revealed that age-related sarcopenia points to a bigger issue in overweight people: chronic inflammation. 
2. Chronic Inflammation Wears Out Your Body
Chronic inflammation is such a prevalent issue among people aged above 40, scientists have coined it as “inflammaging”. 
Some even describe chronic inflammation as the harbinger of the aging process.
When the inflammation level is high for a long period of time, your cells are constantly damaged and are unable to function fully. You may start to experience joint pain, digestive issue and fatigue.
Research has shown that chronic inflammation is a huge contributor to weight gain as well.
The Journal of the American Medical Association did a huge study on over 16,000 overweight people. It revealed that overweight adults all had a consistently higher amount of an inflammatory protein in their blood. It’s called the C-reactive protein (CRP). 
When CRP reaches your brain, it damages your blood-brain barrier. This barrier is an important shield that blocks toxic substances and harmful bacteria from entering your brain, keeping it protected.
But when CRP damages your blood-brain barrier, it creates small holes and allow toxins to enter. This can greatly effect your brain function in negative ways.
Over time, your brain won't be able to recognize that your stomach is full. This will make you feel hungry constantly, even after you eat a large meal. Such excessive cravings will cause you to consume more calories than you need, making it tough to even go on a diet.
Additionally, your brain can’t fully trigger your metabolism, causing your body to burn less calories. Even if you worked out all day, you would barely be able to burn the calories gained from your bowl of pasta.
If you’re serious about your weight loss, it’s essential to target your chronic inflammation issue.
Recently many people has started taking turmeric as an effective solution for chronic inflammation. If you're looking to supplement with turmeric to reduce inflammation, find one with bioperine as it increases the absorption rate of turmeric by the body.
3. Leading an Unhappy Life Makes You Binge
A study from the Office for National Statistics (ONS) revealed that people age 40 to 59 are the most unhappy and most anxious people. 
At this age, you have to juggle between work, looking after your children and taking care of elderly parents. You have a lot of responsibilities at hand and it’s hard to make time for yourself.
Naturally, you’ll be under immense stress. This causes your body to produce a harmful stress hormone called cortisol. This substance makes you crave for more food, while slows down your body’s metabolism and making it store more fat.
In fact, a Health Psychology Program ran by the University of California has shown that when women are under stress , they will secrete more cortisol and had a consistently higher craving for unhealthy snacks, especially sweet food. 
If you are stressed out, chances are you don’t have time to exercise too. There’s little chance for you to burn those calories you’re eating.
This is a common and unhealthy lifestyle for many people aged above 40. Such unhealthy lifestyle further exacerbates your chronic inflammation.
And social responsibilities only make it more difficult for your body to lose weight.
Besides taking time out to relax and destress, one effective solution for stress and anxiety is probiotic. Recent research has shown that certain probiotic strains reduces stress and improve emotional well-being.
4. Deteriorating Gut Health Allows Harmful Bacteria to Invade Your Body
When researchers from Gut Microbes association studied the gut flora of older folks, they discovered several trends.
People above 40 tend to lose a significant portion of their beneficial bacteria and have a higher proportion of harmful bacteria. They have a lower diversity of flora as well. 
This means your gut weakens and you will be more susceptible to a wider variety of infections and frailty.
As your gut weakens like this, more of the harmful bacteria will seep into your blood and enter your blood brain barrier. This will affect your brain function, similar to how chronic inflammation works. Your brain will keep thinking that you’re hungry all the time and is less efficient in triggering your body’s metabolism.
To top that off with an unhealthy lifestyle, having a diet loaded with fats and carbs will just worsen your gut health. And if you’re on long-term medication, you may lose even more of beneficial bacteria.
This explains why overweight people tend to suffer from gut problems like indigestion and bloatedness too.
Even though poor gut health leads to weight gain, you can start taking more probiotics to improve your gut health. In fact, certain strains of probiotic has been shown to aid weight loss.
5. You Could Be "Resistant" to Weight Loss
Have you ever lamented that no matter how hard you exercise, how much effort you put into dieting, that tire of belly fat simply won’t shrink?
Some scientists have termed this condition as “Weight Loss Resistance”.
This condition is often a combination of chronic inflammation, poor gut health occuring in your body and myriad of other contributing factors. Your brain gets subjected to harmful bacteria and toxins, making it unable to trigger the fat-burning processes in you, and is common among people above 40 years old.
It probably explains why you may have been a serial dieter. You had tried several diets in the past, but your food cravings blew away your motivation. It’s hard to resist that cheesecake even after you had a huge dinner.
You may have lost weight, but you gained it back quicker than you can snap your fingers.
Stop The Fat, Before It Stops You
You have to take action early and put a stop to your weight gain.
The American Society for Clinical Nutrition estimates that obesity claims approximately 400,000 lives every year. 
That’s a huge number to avoid... if you want to be there for your family and your grandchildren. Put a stop to those fats, before they put a stop on you.
Good news is you can take action and put your body back on track.
Scientists have recently revealed 3 specific strains of probiotics that has made women
lose over 10 pounds in the first 8 weeks of their clinical studies.
