Research studies demonstrated that brain health may ultimately be associated with obesity. Scientists also reported that obesity affects the overall size and function of the brain, as well as specifically altering certain neuronal circuits. By way of instance, a recent research study found a connection between smaller brain size and lower gray matter volume associated with obesity around the stomach region. Another research study also found that the prefrontal cortex, an essential area in the brain that plays a fundamental role in thinking, planning, and self-control, is less active in people with obesity. Several other research studies have also found further evidence showing the connection between brain health and obesity. Dr. Ilona A. Dekkers, from the Leiden University Medical Center in the Netherlands, utilized MRI scans in several recent research studies to understand how obesity can affect the size and function of the brain. Dr. Dekkers reported lower gray matter volume in people with obesity. According to the research studies, people with obesity also had white matter volume changes in a variety of brain regions. In the following article, we will ultimately discuss how obesity can affect brain health.

Obesity Can Change How You Look and FeelRecent research studies demonstrated that obesity can affect brain health. Ranjana Mehta, an assistant professor of environmental and occupational health at the Texas A&M Health Science Center School of Public Health in College Station, Texas discussed how obesity doesn’t simply affect how you look and feel, it can affect your mental and physical health as well as cause a variety of brain health issues. Ranjana Mehta, who received funding from the National Institute on Aging to evaluate how obesity can affect brain health in older adults determined that obesity can affect brain structure and cause atrophy.
Obesity Can Alter the Way You MovePeople with obesity have to carry extra weight that can add stress and pressure on the joints, ultimately altering movement. Scientists utilized imaging methods and techniques to demonstrate how people with obesity often have to utilize more mental resources when walking, although they were still able to walk as well as healthy people. Moreover, research studies found that stress and pressure from carrying extra weight affected brain activity in people with obesity compared to healthy people. The additional mental burden associated with obesity may also cause individuals to become tired more quickly.
Obesity Can Influence Your MemoryObesity is associated with poor memory, often making it difficult to remember past events in young adults between 18 to 35 years of age, according to a research study published in the Quarterly Journal of Experimental Psychology. Further evidence also suggests that people with obesity experience memories in slightly less detail and/or less vividly compared to healthy people. Lucy Cheke, lead researcher and a lecturer in the department of psychology at the University of Cambridge in England discussed that memory can play a fundamental role in regulating what we eat and how we lose weight.
Obesity Can Lead to Dementia and Alzheimer’s DiseaseOther research studies demonstrated that obesity in people during their 40s, 50s, and even early 60s is associated with an increased risk of developing dementia and Alzheimer’s disease. According to Heather Snyder, senior director of medical and scientific operations at the Alzheimer’s Association, mid-life obesity is connected with an increased risk of developing dementia and Alzheimer’s disease over time with age. Scientists still don’t understand how obesity can cause dementia and Alzheimer’s disease, however, obesity can ultimately affect heart health which can play a fundamental role in brain health.
Obesity Can Cause DepressionAs previously mentioned, obesity can ultimately affect mental and physical health. Dr. Susan McElroy, chief research officer at the Lindner Center of HOPE, a private psychiatric facility in Mason, Ohio, who has also evaluated the connection between obesity and mental health issues described that obesity can cause depression. Scientists believe that just like obesity can cause major depression, it may also cause bipolar disorder. Furthermore, scientists believe that depression itself may, in turn, also cause obesity. McElroy suggests that obesity and depression both need to be addressed to make progress.
Obesity Can Rewire the Pleasure-and-Reward CenterIn a research study published in the Journal of Neuroscience, a region of the brain, known as the striatum, was demonstrated to be less active in people with obesity. The striatum plays a fundamental role in controlling the pleasure-and-reward center in the brain associated with the release of the neurotransmitter or chemical messenger known as dopamine. The release of dopamine we get from eating certain foods, such as foods that are high in sugars and fats, can have a dulling effect in people with obesity which scientists believe can cause a person to overeat to regain that fleeting sense of pleasure.

In the following article, we will ultimately discuss how obesity can affect brain health, from changing how you look and feel to causing depression. – Dr. Alex Jimenez D.C., C.C.S.T. Insight

Neurotransmitter Assessment FormThe following Neurotransmitter Assessment Form can be filled out and presented to Dr. Alex Jimenez. The following symptoms listed on this form are not intended to be utilized as a diagnosis of any type of disease, condition, or any other type of health issue.
Additional Topic Discussion: Chronic PainSudden pain is a natural response of the nervous system which helps to demonstrate possible injury. By way of instance, pain signals travel from an injured region through the nerves and spinal cord to the brain. Pain is generally less severe as the injury heals, however, chronic pain is different than the average type of pain. With chronic pain, the human body will continue sending pain signals to the brain, regardless if the injury has healed. Chronic pain can last for several weeks to even several years. Chronic pain can tremendously affect a patient’s mobility and it can reduce flexibility, strength, and endurance.
Neural Zoomer Plus for Neurological DiseaseDr. Alex Jimenez utilizes a series of tests to help evaluate neurological diseases. The Neural ZoomerTM Plus is an array of neurological autoantibodies which offers specific antibody-to-antigen recognition. The Vibrant Neural ZoomerTM Plus is designed to assess an individual’s reactivity to 48 neurological antigens with connections to a variety of neurologically related diseases. The Vibrant Neural ZoomerTM Plus aims to reduce neurological conditions by empowering patients and physicians with a vital resource for early risk detection and an enhanced focus on personalized primary prevention.
Food Sensitivity for the IgG & IgA Immune ResponseDr. Alex Jimenez utilizes a series of tests to help evaluate health issues associated with a variety of food sensitivities and intolerances. The Food Sensitivity ZoomerTM is an array of 180 commonly consumed food antigens that offers very specific antibody-to-antigen recognition. This panel measures an individual’s IgG and IgA sensitivity to food antigens. Being able to test IgA antibodies provides additional information to foods that may be causing mucosal damage. Additionally, this test is ideal for patients who might be suffering from delayed reactions to certain foods. Utilizing an antibody-based food sensitivity test can help prioritize the necessary foods to eliminate and create a customized diet plan around the patient’s specific needs.
Gut Zoomer for Small Intestinal Bacterial Overgrowth (SIBO)Dr. Alex Jimenez utilizes a series of tests to help evaluate gut health associated with small intestinal bacterial overgrowth (SIBO). The Vibrant Gut ZoomerTM offers a report that includes dietary recommendations and other natural supplementation like prebiotics, probiotics, and polyphenols. The gut microbiome is mainly found in the large intestine and it has more than 1000 species of bacteria that play a fundamental role in the human body, from shaping the immune system and affecting the metabolism of nutrients to strengthening the intestinal mucosal barrier (gut-barrier). It is essential to understand how the number of bacteria that symbiotically live in the human gastrointestinal (GI) tract influences gut health because imbalances in the gut microbiome may ultimately lead to gastrointestinal (GI) tract symptoms, skin conditions, autoimmune disorders, immune system imbalances, and multiple inflammatory disorders.
