Leptin Resistance Can Cause That "Always Hungry" Feeling - It’s Never Too Late Coaching

Leptin Resistance Can Cause That “Always Hungry” Feeling

.

It’s not only insulin resistance we have to tackle when we’re having trouble losing weight.  Gotta investigate leptin resistance too.

Who knew about leptin resistance?  Who knew about leptin’s role in suppressing appetite?  I sure didn’t.

It wasn’t until just a few years ago that the media started covering its influence on hunger.

However, now I understand its key role in appetite suppression. .

Now, I’m all about maximizing leptin sensitivity.

Let’s get nice and cozy with leptin, our newest BFF.

Leptin is a hormone secreted by our fat cells.  It affects the way the body stores and burns energy. Sometimes it’s known as the “satiety hormone” because it reduces appetite.

The primary role of this hormone is to regulate the overall relationship between hunger and activity in your body.

Your fat cells rely on leptin levels to determine how much energy/fat is available for your daily use.

Depending on your leptin levels, your brain directs your eating and activity behavior.

From an evolutionary standpoint, body fat allowed us to survive periods of food shortage or illness.

The leptin system evolved to keep humans from starving or overeating.  Either one would have put our survival in jeopardy.

Today, leptin is very effective at keeping us from starving.  But this mechanism is also supposed to stop us from overeating.  Yet, for too many of us, it’s not functioning as Mother Nature intended.

Your fat cells secrete leptin in response to the amount of fat already stored on your body.

The hormone insulin stores blood sugar (glucose) from your bloodstream in your fat cells to provide energy for future use.

Leptin has a different job.

Your bloodstream carries leptin into your brain.  Once there, it signals your hypothalamus, that part your brain that controls when and how much you eat.

It tells your brain how much body fat you have stored in your cells.  This helps regulate energy intake and energy expenditure.

High levels of leptin tell your brain that you have plenty of fat stored and quiets your hunger.  Low levels tell your brain that fat stores are shrinking and stimulates your hunger.

In addition, leptin has other functions related to fertility, immunity and brain function.

Here’s how leptin sensitivity should work.

When your leptin levels are low, your brain receives leptin’s signal telling you to conserve energy.  Slow down your physical activity.  Hunger grows.  Time to eat!

In response, your body slows your metabolism and you become more sedentary.

Once you eat again, rising leptin signals your brain that there is enough fat in storage. Rising leptin levels tell your brain to stop eating.

You’ve got enough stored energy to get moving again without putting your very survival at risk. Winning!

It’s this interplay that keeps your body fat and energy levels balanced.

This kind of system is known as a negative feedback loop.  It’s similar to the control mechanisms for many different physiological functions, such as breathing, body temperature and blood pressure.

A counter-intuitive reality about leptin levels, satiety and obesity.

Remember that leptin levels are lower in thin people and higher in those carrying around more fat.

Given the way leptin is designed to work, you’d quite rightly hypothesize that people carrying extra weight would have a lot of circulating leptin.  And that this high level of leptin, therefore, should naturally inhibit their hunger and limit their food intake.

In other words, their brains should recognize that they have plenty of energy stored in all those fat cells and respond accordingly.

Although you’re making what seems to be a logical assumption, sadly, you’re mistaken if someone is actually leptin resistant.

Leptin resistance contributes to metabolic syndrome and obesity.

Frustratingly, for many over weight people their leptin signaling mechanism is not working as designed.

While copious leptin may be present, the brain doesn’t see it.  No signal that indicate satiety is getting through.  Hunger continues despite all that available stored energy.

Leptin resistance is believed to be one of the main biological contributors to obesity.

When your brain doesn’t receive the leptin signal, it erroneously thinks that your body is starving.  Even though it has more than enough energy stored in existing fat cells.

This makes your brain change its behavior in order to replenish body fat.

Your brain then encourages you to:

  1. Eat more: Your brain thinks that you must eat in order to prevent starvation.
  2. Reduce energy expenditure: In an effort to conserve energy, your brain decreases energy expenditures and even burns fewer calories at rest.

Can you see how willpower is not the issue here?  How willpower can not over power deep, biological hunger?

Eating more and exercising less is often NOT the underlying cause of weight gain.

Actually it’s quite possibly a consequence of leptin resistance, a frustrating, aggrevating hormonal defect.

If you’re struggling with weight loss due to leptin resistance, white-knuckling your way to your desired weight is nearly impossible.  The leptin-driven starvation signal drives this always hungry feeling.

One of the main players in this unfortunate scenario of this disregulation is insulin.

According to Robert Lustig MD:

When insulin levels are chronically high, there is a breakdown in the hormone pathway which signals the brain to tell the body to stop storing energy in fat and burn it. Obesity is the result.

The good news is that we can do something about chronically high insulin to address both insulin and leptin sensitivity.

According to Healthline, several potential mechanisms driving leptin resistance include:

  1. Inflammation: Inflammatory signaling in your hypothalamus is likely an important cause of leptin resistance in both animals and humans.
  2. Free fatty acids: Having elevated free fatty acids in your bloodstream may increase fat metabolites in your brain and interfere with leptin signaling.
  3. Having high leptin: Having elevated levels of leptin in the first place seems to cause leptin resistance.  A vicious cycle.

Most of these factors are amplified by obesity,  They can trap you in another in another vicious cycle of weight gain and becoming even more leptin resistant over time.

According to Healthline, it’s possible to reverse leptin resistance

The best way to know if you are leptin resistant is to look in the mirror.

If you have a lot of body fat, especially around the belly area, that’s a reliable indicator.

Some researchers believe that reducing diet-induced inflammation may help reverse leptin resistance.

The bottom line is that focusing on an overall healthy lifestyle helps.

There are several things you can do starting today to address leptin resistance.

  1. Avoid processed food: Highly processed foods may compromise the integrity of your gut and drive inflammation.
  2. Eat soluble fiber: Eating soluble fiber can help improve your gut health and may protect against obesity.
  3. Exercise: Physical activity may help reverse leptin resistance.
  4. Sleep: Poor sleep is implicated in problems with leptin.
  5. Lower your triglycerides: Having high triglycerides can prevent the transport of leptin from your blood to your brain. The best way to lower triglycerides is to reduce your carb intake.
  6. Eat protein: Eating plenty of protein can cause automatic weight loss, which may result from an improvement in leptin sensitivity.

Alas, there’s no magic pill to override leptin resistance.

Once discovered in 1994, leptin caused quite the stir among scientists.  They hoped to create a drug to help people control their appetite and their weight.

But they were in for an unpleasant surprise when they made this counter-intuitive discovery.   They found that people with obesity had plenty of leptin in their bodies. yet continued to eat and gain weight.

And to their further disappointment, they couldn’t defeat leptin resistance with leptin supplements either.  The supplements couldn’t pass through the blood-brain barrier.  Instead, they’re metabolized by the body.

The It’s Never Too Late Weight Loss program helps you create a lifestyle plan that addresses insulin and leptin resistance.

Though there is no one and done way to eliminate leptin resistance, long-term lifestyle changes are your proven ticket to better health and well-being.

When you want to lose weight and keep it off, you have to take a 360 approach.  There are many factors that could be undermining weight loss.

Creating sustainable lifestyle changes are the foundation to overcoming insulin and leptin resistance.  And overcoming stalled weight loss results too.

Diets don’t work.  We all know that.  Systematically improving lifestyle choices does bring results.

It’s time to take me up on my offer for your FREE Strategy Call so you can jump start weight loss.
