Intermittent Fasting and Brain Function

By Kirsten Maxwell April 3, 2023 19 mins read 128 Views

Intermittent fasting is a time-restricted eating pattern where you consume less than your usual intake for a certain window of time each day.

Research has shown that periods without food can spur the creation of new brain cells in your hippocampus area of the brain, a key part of memory. It also increases the amount of a brain protein called BDNF (brain-derived neurotrophic factor) in your brain.

Autophagy

Autophagy is a process in the body that recycles old, damaged, and dead cells into new ones. It's an essential cellular function that can help slow down aging, protect against infections, and defend against certain cancers.

It also plays an important role in preventing oxidative stress and helping to maintain brain function. However, scientists still don't fully understand the impact of autophagy on human health.

Studies on autophagy have typically been done on mice or insects. This makes it hard for researchers to know how fasting or calorie restriction affects autophagy in humans.

Ghrelin

Throughout the day, levels of ghrelin rise before and after meals. People who have high body fat tend to have higher ghrelin concentrations than lean people.

Intermittent fasting is a type of diet that allows you to go without food for a period of time, allowing your body to conserve energy. This can help you lose weight and improve your health, but it's not recommended for everyone.

One reason is that it can cause a drop in blood sugar, which can make you feel shaky and tired. It's also not a good choice for people with diabetes or if you have a history of eating disorders.

Using a mice model, we have found that ghrelin receptors in the hippocampus are activated by glutamate, which is thought to be involved in learning and memory. The peptide increases synaptic accumulation of glutamate receptors of the AMPA subtype and promotes long-term potentiation, a form of synaptic plasticity that is thought to underlie learning.

BDNF

Intermittent fasting triggers many of the same reactions that physical exercise does to our bodies: protein sparing, reduction of inflammation and a higher production of BDNF. These processes help stimulate proper brain function by promoting cell repair and growth and strengthening connections in the brain.

BDNF is a crucial neurotransmitter that helps control communication within our brain. Its loss in our bodies has been linked to cognitive problems in aging, such as Alzheimer’s disease.

BDNF is also crucial for pain processing in the nervous system, and a number of studies have shown that its release in the spinal cord is unaltered following nerve injury. This is supported by a conditional knockout mouse study that found selective deletion of BDNF from primary afferent neurons results in strong suppression of nerve injury-induced mechanical allodynia but no effect on inflammatory pain behavior (Zhao et al 2006).

Metabolic Switching

When you fast, your body uses stored fatty acids and ketones as fuel. This can help you keep blood sugar levels in check, which is important for brain health.

IF involves limiting food intake to only a few meals a day and alternating between eating and fasting periods. These are typically 12 to 48 hours with periods of unrestricted eating between them.

The fasting period depletes your liver’s glycogen stores and gives your body the time it needs to burn fatty acids instead. The fatty acids and ketones you create can lead to increased brain function and resistance to oxidative stress.

Metabolic switching has been shown to have positive effects on a variety of factors associated with the body’s metabolic homeostasis, including energy metabolism, lipid synthesis and oxidation, glycolysis, gluconeogenesis, protein synthesis and mitochondrial activity. It also promotes autophagy, DNA repair, and the expression of BDNF, a brain-derived neurotropic factor that strengthens neurons’ defenses against inflammation and oxidative stress.

Frequently Asked Questions

Can I drink water if I am intermittent fasting?

You can still drink water during intermittent fasting. Your body will be more balanced if you keep it hydrated. It is important to stay hydrated when fasting for long periods of time. Certain vitamins and minerals can be eliminated through sweat and urine. It's also beneficial for digestion and detoxification processes in the body, as water helps flush away toxins from the body. In the end, staying hydrated is crucial to an effective intermittent fasting program and should not go unnoticed!

Is 16/8 Intermittent Fasting right for me?

It is crucial to examine your personal lifestyle and how intermittent fasting affects your dietary choices. 16/8 intermittent fasting refers to a way of eating within an 8 hour window and fasting for 16 hours each day. This intermittent fasting method has been proven to have numerous health benefits. However it is important you research it to make sure it is right for you.

It will be easier for you to make this choice if the details of 16/8 Intermittent Fasting are well understood. The goal is to reduce overall calories without feeling uncomfortable or restricted. This can be as easy as skipping meals throughout the day or eating only certain times of the day. Knowing how much and how frequently you eat will help you make a plan to achieve your nutrition goals.

Understanding your body and its needs is key to deciding whether 16/8 would suit you. Considerations such as activity levels, hormonal imbalances and medical conditions, stress levels, genetics, age, and genetics all come into play when assessing one's diet and food choices. You might find intermittent fasting not to be best suited for your needs or those of your family members. Many diets are available, from low-carb to high fat and healthy eating plans. So don't let it discourage you if one doesn’t suit your needs.

Everybody is different. You can choose to put as much effort and energy into researching all diet options in order to find the one that suits you best. After researching 16/8 intermittent fasting, be honest about assessing yourself and finding out if this way of eating works right for who you are before fully committing in the long run!

How much weight can you lose with intermittent fasting in a single week?

Is it possible to calculate how much weight you should try to lose each week by doing an intermittent fast? You need to think carefully about the answer.

The key is to be balanced. Achieving too ambitious goals can lead you to burnout, injury, and even worse, burnout. Plan your weight loss goals by taking into consideration lifestyle factors like nutrition, sleep, and hydration. Counting calories might be a helpful tool, but it should not become the sole focus of your plan.

Also, it is important to know what sort of results are possible. For example, losing more than 1 - 2 kilograms per week may put undue pressure on your body. While trying to lose as little as 1 kilo could produce minimal or no visible results. Measurements of the body are a better way to track progress than just watching the scales change.

Talk with a professional dietitian to get additional support throughout your journey. A neutral opinion can help you make sure that whatever goals and outcomes you have set for yourself are realistic, safe, and possible with long-term results.

Statistics

The rigor of fasting also varied, with several studies allowing 25% of regular caloric consumption during fasting periods. (ncbi.nlm.nih.gov)
In 2018, 63.1% of Canadian adults were overweight or obese. (ncbi.nlm.nih.gov)
consumption was examined in 1 study, which compared dietary fat intake of 45% versus 25% at the expense of carbohydrate intake. (ncbi.nlm.nih.gov)
When diet composition was controlled, most protocols were consistent with Health Canada and American Heart Association guidelines: 55% carbohydrates, 20% fat, and 25% protein. (ncbi.nlm.nih.gov)
