Brain activity may be affected by obesity and obesity

What is brain health?

Brain Health is an emerging and growing concept that encompasses neural development, plasticity, functioning, and recovery across the life course.

Staying fit and maintaining your weight has been highlighted many times for the benefits those bring to your entire body—such as warding off cancer or death related to cardiovascular events—but a new study suggests keeping a stable weight can impact your brain health as well.

The researchers found that participants who had a BMI corresponding with overweight or obese were more likely to develop dementia. This outcome supports previous studies that indicate obesity is a risk factor. Scientists have been struggling to find the cause of Alzheimer’s and other types of dementia.

  • According to new research published in the Journal of Alzheimer’s Disease, a higher BMI means less blood flow to your brain, which means a higher risk of dementia—especially Alzheimer’s disease.
  • However, BMI itself isn’t a measure of your “health,” but rather a measure of your size.
  • The key takeaway is staying fit is key to keeping your brain healthy in the long term.

For the most part, they blame it on genetics, which we can do very little about. But now a new study published in the journal Brain Sciences has revealed a cause of dementia that’s quite manageable.

Brain plasticity, or neural plasticity, is your brain’s ability to grow, reorganize itself, and rewire its neural connections when conditions require it.

For example, if you’ve had a stroke or brain injury that compromises one part of your brain, neural plasticity allows neurons to make new connections so that those old brain functions are taken over by another part.

This is also important when you learn something new. When you learn to play the guitar, new neural connections must be formed.

As you age, some parts of your brain may no longer develop as well as they used to, or other parts may be damaged by reduced blood flow. Then, neural plasticity allows you to develop new neural pathways to replicate the functions of the damaged pathways.

The research – brain health and obesity

Researchers from the University of South Australia and Deakin University set out to examine whether obesity affects the plasticity of brains by examining the brains of 14 obese and 16 normal-weight subjects.

All participants were between ages 18 and 60.

The researchers applied pulses of electrical stimulation to their subjects’ brains, specifically to the part of the brain called the motor cortex. This is where intentional movements are planned, directed, and executed.

They wanted to see how strongly the brains of their subjects responded to this electrical stimulation, which they used as an indicator of neural plasticity.

The brains of the healthy-weight group reacted correctly, with a healthy level of neural activity, while the brains of the obese subjects reacted much less.

From this, they concluded that the brains of the obese subjects were unable to react sufficiently to stimuli to grow, learn, and change.

The solution and recommendations – for brain health and lose weight

This means that it is important to lose weight if you want your brain to age healthily, to recover from stroke and injury, and to compensate for small areas of reduced function that inevitably occur with age.

The real breakthrough of this study, however, is that it proves that dementia is not just caused by our genetics and there is something we can do about it.

Healthy ways to lose weight

1. Always Eat Breakfast

Nutrition in the morning is the most important, but also the most easily absorbed by the body. Research shows that people who have breakfast tend to take in more vitamins and minerals and less fat and cholesterol. Eating things that are high in fiber and proteins keeps you feeling full and energized.

These include whole-grain cereals and bread, low-fat milk, fruit, and yogurt. Remember the famous quote “eat like an emperor in the morning, eat like a commoner at noon, and eat like a beggar at night”. Studies show that adults who have a healthy breakfast do better at work, and kids who eat a morning meal score higher on tests

2. Eat slowly

If you eat too much is not good for the digestion of food. Moreover, with the growth of age, the peristalsis of the stomach and intestines will gradually slow down, which will lead to the decline of metabolism. Do you want to lose weight? Cut back on sugar, fat, or carbs. Add protein or vitamins. Meal prep keeps you in control.

3. Have a light diet, less salt, and less oil

Having the right diet can reduce the risk of a range of diseases. Less salt can help keep blood pressure under control and reduce the risk of blood vessel irritation that can easily trigger arteriosclerosis. This habit includes such things as eating more fruit and nuts and avoiding sugary drinks and snacks.

Water: Getting the proper amount of water is extremely important as every cell, tissue, and organ in our bodies needs water. Staying hydrated helps you lose weight.

4. Exercise every day

We know daily exercise is good for optimizing health. As a general goal, aim for at least 30 minutes of moderate physical activity every day. If you want to lose weight, maintain weight loss, or meet specific fitness goals, you may need to exercise more regularly exercise helps control weight, maintain healthy bones, muscles, and joints, and reduces your risk of high blood pressure, heart disease, and diabetes. Get up and move

5. Challenge yourself

Keep both body and mind agile. Challenge yourself to try new experiences and meet new people, putting yourself in situations that previously I probably would have avoided. Why You Should Challenge Yourself? You’ll discover that you are capable of things you didn’t think you were. You’ll also reach new goals you never would have previously thought to even reach for. New skills help keep your brain healthy.

Even if you feel perfectly healthy, there’s still a reason to visit with your primary care doctor at least once a year.

A food supplement or nutritional supplement is a preparation intended to supplement the diet and provide nutrients, such as vitamins, minerals, fiber, fatty acids, or amino acids, that may be missing or may not be consumed in sufficient quantities in a person’s diet.
