Being Overweight May Age Your Brain By 10 Years, Study Finds

Being Overweight May Age Your Brain By 10 Years, Study Finds

You already know being overweight isn’t healthy. It can cause tons of problems, especially later in life. But did you know a study done by the journal Neurobiology of Aging actually took brain scans of overweight and slim people, compared them, and found the overweight people’s brains showed signs of being 10 years older?

Let’s back up. Science proved a long time ago that the white matter in our brain shrinks as we age. This white matter contains connecting branches called axons. These connect neurons together, which is referred to as the “cerebral highway” because there are so many pathways going across your brain where electrical impulses travel as the different parts of your brain communicate.

The Study

Researchers recruited 527 volunteers aged 20 to 87. Each one was classified as either “lean” or “overweight” depending on their body mass. After scanning the brains of all participants, the study authors found that from middle-age onwards, the brains of overweight people tended to shrink more than those in the lean group.

Most of the overweight participants’ brains showed as much shrinkage as lean participants’ brains which were 10 years older. The study’s co-author, Lisa Ronan, explained in a statement that “it isn’t clear why people who are overweight have a greater reduction in the amount of white matter,” adding that “we can only speculate on whether obesity might in some way cause these changes or whether obesity is a consequence of brain changes.”

What Science Shows

Unfortunately, the researchers aren’t sure exactly what causes this effect. They think it may have to do with inflammation. As we get older, we experience higher levels of oxidative stress, which is the production of certain molecules that cause damage to body tissues. Previous studies have shown that this often leads to inflammation, which in turn causes the loss of white matter.

The buildup of fatty tissue causes inflammatory compounds called cytokines to release alongside inflammatory hormones like leptin. Researchers believe this may partially explain the reason behind obesity causing such extreme signs of aging.

Thankfully, despite the loss of white matter, overweight people didn’t appear to have lost any cognitive capabilities — meaning they had no problem thinking like everyone else. They also performed just as well as lean people of the same age on IQ tests.

So if you’re overweight, you may want to start thinking about changing your diet and getting proper exercise. Even without shrinkage of your white matter, there are many other consequences of remaining at a high weight.

How to Practice Positive Meditation in 2 Simple Steps

How to Practice Positive Meditation in 2 Simple Steps

Just by simply spending some effort and time, staying positive every day can be easily achieved. All that is required is a fraction of your time, 10-15 minutes a day to cultivate the positive you!

But first, what is really positive thinking? Do you have to be in an upbeat, cheerful and enthusiastic mood all day to be positive minded?

No. Positive thinking simply means the absence of negative thoughts and emotions – in other words, inner peace!

When you are truly at peace within yourself, you are naturally thinking positively. You don’t have to fight off negative thoughts, or search desperately for more positive thoughts. It just happens on its own. And here are 2 positive thinking meditation tips to empower you:

1. Relax as You Meditate

A powerful, simple yet rarely used technique is meditation. Meditation doesn’t have to take the form of static body posture. It can be as simple as sitting in a comfortable chair listening to soothing music. Or performing relaxation techniques such as deep breathing exercises.

Meditation is all about letting go of stressful or worrisome thoughts. That’s it! If you spend just a few minutes per day feeling relaxed and peaceful, you automatically shift your mind into a more positive place. When you FEEL more relaxed, you naturally THINK more positively!

Start with a short period of time, like 5 or 10 minutes a day. You can meditate first thing in the morning, during your lunch break, right before you go to bed at night, or any time. The most important thing is to consciously let go of unproductive thoughts and feelings. Just let them go for those few minutes, and you may decide not to pick them back up again at all!

2. Practice Daily Affirmations

Positive affirmations can be used throughout the day anywhere and at anytime you need them, the more you use them the easier positive thoughts will take over negative ones and you will see benefits happening in your life.

What are affirmations? Affirmations are statements that are used in a positive present tense language. For example, “Every day, in every way, I’m getting better, better and better” is a popular affirmation used by the late Norman Vincent Peale.

So how does one go about using positive affirmations in everyday life? Let’s look at some guidelines to follow when reciting your daily affirmations.

  1. Use first person pronouns in your message (I)
  2. Use present tense (I have)
  3. Use positive messages (I am happy)
  4. Repeat your affirmations on a consistent basis

Affirmations have to be said with conviction and consistency. Start your day by saying your affirmations out loud. It wouldn’t take more than 5 minutes to repeat your affirmations; yet when done consistently, these positive affirmations will seep into the subconscious mind to cultivate the new positive you.

Here’s an example of a “success affirmation” you can use on a daily basis:

I am successful in everything I do. Every venture I get into returns wealth to me. I am constantly productive. I always perform to the full potential I have and have respect for my abilities.
My work is always given positive recognition. I augment my income constantly. I always have adequate money for everything I require. I spend my money prudently always. My work is always rewarded.
