Intermittent fasting helps you eat fewer calories while boosting metabolism and improving your overall health. In modern times people over consume food; which can potentially direct to Alzheimer’s disease, Diabetes, and Heart attack; which are leading causes of death in the United States. In the article of impact of intermittent fasting on health and disease processes; rats and mice are the main test subjects used to experiment the benefits of intermittent and periodic fasting. This paper will focus on the benefits found from performing intermittent fasting; specifically, on neurological disorders such as Alzheimer’s disease, Parkinson’s diseases, stroke and cancer.
Previous research on intermittent fasting have come up with the hypothesis, that “because aging is the major risk factor for neurodegenerative disorders, and because intermittent fasting can counteract aging processes, intermittent fasting may protect neurons in animal models of the disorders.” Experiment done on diseased rats and mice; resulted in the counteract of neurons degeneration process. Degeneration and death of neurons occurring in Alzheimer’s disease, Parkinson’s diseases, and stroke; causes impaired

“Several transgenic mouse models of AD have been generated that exhibit age-related accumulation of Aβ without or with Tau pathology, and associated learning and memory deficits.” Mice with Aβ and Tau pathology that were subjected to intermittent fastening; results indicated that it can protect neurons against dysfunction. Other experiment results involving the “administration of alternate day fasting several months prior to Kaini acid suministration, the animal was more resistant to the degeneration; and learning and memory deficits where improved.” This type of fasting no only made the diseased animal resistant; but also improved it’s
In a typical healthy adult, reductions in food intake is quite rare. Reducing the caloric intake of a typical adult inhibits our ability to fight diseases.
The less severe disadvantages surrounding the diet consist of physical weakness, low energy level, slower reaction times, headaches, and dehydration. These less dangerous, yet clearly relevant reactions are due to the elimination of carbohydrates from the diet. Blood sugar levels become very low when carbohydrates are not ingested, causing physical pain and weakness as well as a slower reaction time. Headaches also occur as a natural response mechanism that act as signals for the body that carbohydrates are needed in order to prevent further problems. Moreover, when the body breaks down stored fats t...
The Mayo Clinic Diet is designed to change your lifestyle by replacing bad habits with new, healthy ones. There is no need to eliminate foods, just reduce the portion of certain ones. The goal of the diet is to lose excess weight, and to then maintain a healthy weight for life. Changing your daily routine and adding new habits is what it focuses on. The Mayo Clinic Diet was developed by medical professionals. It is known to be a diet you can stick with for life, not just a fad or quick fix.
Fasting improves the brain health and its nervous system as a whole. In addition, it increases a protein known as BDNF (Brain derived Neurotrophic Factor). This type of protein is vital in preventing stressed neurons from being inactive or dying. A low level of BDNF is
Alzheimer’s disease or AD is an incurable disorder of the brain that results in loss of normal brain structure and function. In an AD brain, normal brain tissue is slowly replaced by structures called plaques and neurofibrillary tangles. The plaques represent a naturally occurring sticky protein called beta amyloid and in an Alzheimer’s brain, sufferer’s tend to accumulate too much of this protein. Neurofibrillary tangles represent collapsed tau proteins which, in a normal brain along with microtubules, form a skeleton that maintains the shape of the nerve cells. In Alzheimer’s disease, the tau proteins break loose from their normal location and form tangles. Without the support of these molecules, nerve cells collapse and die. As normal brain structure is lost with progression of the disease, brain function also degenerates. Patients afflicted with Alzheimer’s disease display a gradual mental decline. Initially, and most apparently, there is a loss of short-term memory. Eventually, as a patient progresses to later stages of the disease, the brain becomes so damaged that patients can no longer communicate or recognize immediate family or even themselves. They have difficulty walking and standing and frequently fall. In the final stages, they lose bladder and bowel control and have difficulty with swallowing, frequently leaving them malnourished and dehydrated. Eventually, they are forced to remain bedridden and, without the help of life-prolonging measures provided in a hospital, die. However, this level of deterioration is severe and may take as long as twenty years. Because of the disease’s slow progress and its usual later start in a person’s life, a victim of AD will usually die first of natural causes. Under the objectives ...
Nutrition plays a significant role in the human lifecycle because it provides energy, helps prevent diseases and promotes growth. The first documented evidence associating dietary restriction and aging came in 1935 in a study conducted by McCay et al that found that reducing the amount of calories consumed by 20% without causing malnourishment increased the lifespan and resistance to age related diseases in a rodent model (Colman et al., 2009; Sinclair, 2005). Typically a reduction of 10-40% of calorie intake is suggested by several authors as being effective in lengthening life, although a recent study using 30% dietary restriction was found to be ineffective in doing so in rhesus monkeys (Mattison et al., 2012).
...brain and malnutrition. Therefore, one’s diet is not only crucial for the physical well being but also their mental.
Almost everyone attempts to live a healthy lifestyle. A healthy lifestyle is not only important for physical health but mental health as well. Every day, individuals consider changing their eating habits. There are several ways of eating available to chose when aiming for a healthier lifestyle. For example, a multitude of individuals have been converting to the ketogenic way of life. The ketogenic diet was first introduced in the 1920s to help control seizures. There are numerous benefits of the ketogenic lifestyle. The primary reason that various people begin living this way of life is weight loss. They continue the ketogenic lifestyle for the many medical improvements provided by this way of eating. The ketogenic lifestyle is a high-fat
...d, “The Low-fat Study.” He placed 150 MS & Narcolepsy patients on a low saturated fat diet. They were graded by Prof Swank with a neurological disability scale and during the 34 years, some expressed rapid progression of MS and Narcolepsy. Some were confined to using a wheelchair or being in bed rest as well as many others who died. Lowering saturated fat consumption was enough to cause a change in the progression of MS and Narcolepsy. The death rates of poor dieters were much higher than those of good dieters. It is evident that by eating the proper foods and exercising regularly patients experiencing both of these diseases can improve their health conditions. These diseases can happen to people of different ages and races, but following the right treatment, nutrition, and lifestyle can result in a healthy body at any age even with these life altering conditions.
Disease is so persistent, disabling, and costly. Based on postmortem examinations of remaining brain tissues in Alzheimer’s patients, Amyloid plaques, and neurofibrillary tangles are the two main characteristics involved with Alzheimer’s disease. (5) Amyloid-B is a protein that accumulates on the inside and outside of neurons. High levels of amyloid proteins damage axons and dendrites. (3) These damaged axons and dendrites cluster into structures called amyloid plaques, which begin to form before any behavioral symptoms appear (3). As the plaques accumulate, the cerebral cortex, hippocampus, and other areas atrophy or waste away (3). In addition to amyloid-B, these neurofibrillary tangles accumulate from tau proteins (3). Tau proteins are the intracellular support structure for neurons. Tau proteins help assemble and maintain microtubules that transport nutrients along axons (5). However, in Alzheimer’s disease, tau undergoes changes that cause it to bind to itself, resulting in neurofibrillary tangles (5). Therefore, the combination of amyloid and tau produces the behavioral deficits seen in those who suffer from Alzheimer’s disease ...
“Alzheimer's disease is a progressive, degenerative disorder that attacks the brain's nerve cells, or neurons, resulting in loss of memory, thinking and language skills, and behavioral changes” (Alzheimer’s Foundation of America, 2014). AD is a debilitating disease that interferes with the individual’s quality of life and often causes distress to the loved ones around them. The cause of AD is unknown; however, there are some factors that put individuals at risk for developing AD such as: age (gre...
Alzheimer’s is a complex disorder, and it cannot be prevented yet. Researchers have discovered that there might be a possibility that it can be prevented or the symptoms can be delayed through a combination of healthful habits. Research being carried out by scientists, show hope that one day the development of Alzheimer’s disease can slowed down or cured. But essential steps can be taken to delay the arrival of Alzheimer’s. These include lifestyle interventions.

For centuries, many variations of fasting have been used in an attempt to improve health. Recently however, the practicality of long-term fasting has been questioned, therefore causing intermittent fasting to emerge with debatable weight loss results. According to Adrianna Taylor Abbott, in her book Intermittent Fasting, this method of fasting is much more than simply dieting. Rather, it has evolved into a revolutionary way of living life and of improving overall fitness. This review will examine the overall reliability of the book’s claims as well as whether intermittent fasting should indeed be trusted as a viable method for weight loss.
The main cause of eating fast food is that we are running a fast pace life and we seem to find no time in the day to sit down and prepare a healthy food for ourselves. Therefore, fast food restaurants are continuing to grow their business and we are continuing to put our health at risk as consumers. Thus, in my opinion consuming fast food is not a wise choice for any of us and we should stay away from eating it because it has many drawbacks than the benefits. The changes in lifestyle worldwide from past few decades have shown a great impact on the pattern of food consumption. One of the most common trends in consumption of fast food is eating food outside the home. Family work pattern has also changed and as have family structure,
