Hidden Reasons You Gain Weight

I’m sure you’ll agree when I say:

Losing weight is a struggle.

Or is it?

Well, it turns out that losing that belly may not be as difficult as you thought. There are hidden reasons for your weight gain even when you exercise on a consistent basis.

In this article, I’m going to show you  8 hidden reasons you gain weight by explaining what your body is doing. Plus a bonus reason that you probably never heard of.

If you want to know more, all you have to do is read on…


8 Hidden Reasons You Gain Weight (Even Though You Exercise)


Reason #1: Gut Bacteria Digesting Your Food Too Slow

When you eat food, there are healthy bacteria in the stomach to break it down to send it where it needs to go through the body. For some people, even if they eat the same amount of food, they absorb at slower rates. Because of this, the result is slow bowel movements. It’s normal to have them ranging 3 times a day or 3 times per week depending on diet.

So, what gives?

A couple factors play into this, mainly dehydration, medications, or low on fiber. Therefore, the solution is simple and easy.

This issue is solved by eating probiotics like yogurt (and my personal favorite, Kombucha), eating more greens and other fiber-filled foods, and of course, staying hydrated by drinking more water.


Reason #2: Your Thyroid Gland Is Under Active

Another one of the hidden reasons you gain weight is hypothyroidism. An under active thyroid results in “unexplained weight gain or difficulty losing weight.” Meaning, the thyroid gland doesn’t produce enough hormones the body needs. Both sexes can have this issue, although it’s more common in older women.

What’s so important about this small gland in the neck?

Well, the thyroid creates thyroid hormones that influence metabolic rate and protein synthesis. So if this is out of wack, your cycle of breaking and using energy is out of wack.

Although hypothyroidism can’t be cured, it can be controlled. Doctors prescribe a synthetic thyroid hormone called T4 to provide an extra hormone boost.


Reason #3: You Have Vitamin “D”eficiency

As you can tell by the lame title, deficiency in Vitamin D, along with magnesium and iron hurts your progress. When these nutrients are low, you have a lower immune system, lower energy levels, and an altered metabolism. This domino effect influences you to crave caffeine, sweets, and simple carbs for energy and you won’t feel up for working out.

One of the best options against this is to take in these nutrients. But, first, see your doctor because taking in too much could lead to harm as well.



Reason #4: Too Much Stress In Your Life

You probably already know that stress can prevent weight loss. Stress causes many of the issues we face.

But how?

Too much stress leads to the body releasing a hormone called cortisol. Triglycerides, then, relocate to visceral fat cells that increase the storage of body fat.


Well, elevated cortisol levels mean increase blood glucose which means suppressed insulin that tells your body that you’re hungry again. Then the body stores unused blood glucose as body fat which the weight gain you see.

Another effect of high cortisol levels is Crushing Syndrome. Good thing it’s rare. It affects 1 in 50,000 people causing weight gain in chest, face, and stomach.

So stress less to weight less.


Reason #5: You’re Simply Getting Older

It can be all about the life cycle we go through. After 30, our metabolism slows. This means we need more exercise and less food to keep our metabolism going.

Nothing hard, right?



Reason #6: You Have Achy Joints

Musculoskeletal conditions are the most believable excuses you can give yourself for not exercising. (Like saying, “I can’t run because my feet hurt.”)

But that is probably where the weight gain is coming from. Conditions like plantar fasciitis (which affect the feet) or osteoarthritis takes the fun out of exercising because it hurts to exercise. Plus, you must be extremely careful not to cause further harm.

One solution is to consult a physical therapist to design a program for your fitness goal and to walk you through it.


Reason #7: Your Ancestors Hate You

Genetics is one reason that people like to make something seem impossible.

Yes, there are genes (that I’ll get to in a bit) that contribute to weight gain, but that doesn’t mean it’s impossible to lose weight.

The mutated gene for the women is MMP2 and the mutated gene for men is called FTO. These two aid in fat accumulation and weight gain. Freek G. Bouwman and associates at Maastricht University in Holland found these genes and others that can affect that awesome beach body.


We just developed weight gain from our parent’s behaviors. Contributing factors include eating habits like the necessity to finish everything on the plate. The struggle is more difficult as you try to buy healthy foods only to be enticed by the unhealthy pack of honeybuns that a family member put in the cabinet.

Like the old saying, “It’s not that fat doesn’t run in the family. It’s that no one runs in the family.”


Reason #8: The Worst Reason During Our Generation

The last of the hidden reasons you gain weight is from cheap, hyper-palatable junk foods. 

The worst part is food manufacturers make food that’s cheap and taste delicious on purpose. They design food to last long on the shelf and add little value to our bodies, influencing us to carve more without us knowing it. 

Our brains are wired to feel rewarded for sugary and salty treats. Our ancestors had a hard time gathering these foods. When they got ahold of them, the brain congratulated them. And this translates to us today, even as we don’t have trouble gathering it. 

How does this help you gain weight?

Excessive sugar may cause leptin resistance. (More on that later.) It also tricks you into buying more and put on the extra pounds without you realizing it. 

Aggressive marketing tactics don’t help either. Commercials on T.V. and branding to children make it harder to shy away from these foods. You tell yourself, “I’ll just have one.” But we all know the Lay’s slogan, “Bet you can’t eat just one!” They are daring us to eat more.


Bonus Reason: You Have Leptin Resistance

As explain above, sugar can cause leptin resistance. Leptin is a hormone made by adipose cells to help regulate energy balance by communicating to your body that you are full. We all have these but some people can have resistant signals which don’t tell you that you are full. 

Be sure to check with your doctor to test for this hidden reason. 


So, you’ve learned the 8 hidden reasons you gain weight even with exercise. Our bodies go through a lot to break down and use energy. Because of this, functions can get out of hand.
