When it comes to fasting, its all about implementation.
I mean, if you think about it, our ancestors relied on their immediate environment for food and when there wasnt any, they went without. Our bodies are designed to be able to withstand the effects of zero food intake and certain studies have actually found that our bodies mayneedsmall periods of zero food consumption.With that said, we no longer live off of our immediate environment and our bodies are no longer trained to go without food consumption for long periods.
So, what does that mean for the fasting trend thats reared a popular surge in the health world?It means that there is a lot of education that needs to go along with the practice. While many studies have found health benefits in certain fasting practices, the implementation of said practices needs to be better bolstered in order to avoid health issues.
If fasting is not implemented appropriately it can lead to severe dehydration, heartburn, fainting spells, drastic mood swings, difficulty sleeping, increased stress and anxiety, and severe headaches. Plus, there is fallout from these symptoms. For instance, fainting spells can lead to driving accidents or other bodily harm such as broken bones and concussions or worse. Mood swings, stress, anxiety, and irritability can affect your relationships at home and work. Heartburn may make it difficult to enjoy food during the periods that you can eat.
Yet, the most dangers aspect of fasting is dehydration.
Our bodies may be designed to forego food, but we are not designed to forego water. Dehydration leads to fatigue, dizziness, confusion, nausea, and even changes in your stool composition and color. Plus, for those that suffer from other medical conditions, dehydration can exacerbate symptoms and worsen said conditions.

Therefore, by removing food intake, youll need to increase fluid consumption to moderate the deficiency.
Speaking with your doctor about hydration needs during a fast is super important, especially since hydration intake is incredibly individualized for your body.
Listen to your body and drink when youre thirsty. Most people who fast aim for 8.5 [to] 13 cups (2-3 liters) of water over the course of the day, while many health authorities recommend the 88 rule eight 8-ounce glasses (just under 2 liters in total) of fluid every day.

Insulin is a hormone that allows cells of the body to take in glucose to be used as fuel or stored as body fat. Over the last few decades, insulin has been found to be one of the most important hormones in the human body and can wreak havoc when it doesnt function appropriately or for those that dont produce enough or any insulin.
Insulin resistance refers to a condition when cells of the body dont respond properly to the hormone insulin and it can be a precursor to type 2 diabetes, gestational diabetes, and prediabetes. Basically, insulin doesnt respond as thoroughly to the consumption of glucose (sugar) and therefore glucose is more likely to build up in the blood leading to high blood sugar levels.
Fasting has been found, through recent studies, to improve blood sugar control, which could be especially useful for those at risk of diabetes, and those who have insulin resistance. Not only does it have to do with forgoing food for a period of time, but fasting specifically intermittent and alternate-day fasting is also a great method for those seeking to limit calorie intake which has been found to be an effective way of reducing insulin resistance.

Along with fasting, inflammation is a hot button topic in the health world these days. This is for good reason. Research has discovered that chronic bodily inflammation is linked to the development of chronic conditions, such as heart disease, cancer and rheumatoid arthritis, and is an underlying cause of certain symptoms related to many autoimmune diseases.
Fasting has been found to help decrease levels of inflammation and help promote better health. Two specific studies highlight these health benefits.
One study performed by theDepartment of Clinical Nutrition at the University of Hail in Saudi Arabia entitledIntermittent fasting during Ramadan attenuates proinflammatory cytokines and immune cells in healthy subjectsshowed that intermittent fasting for one month significantly decreased levels of inflammatory markers.Another studyperformed by the Department of Biochemistry at the Maltepe University in Istanbul, Turkey entitledInterleukin-6, C-reactive protein and biochemical parameters during prolonged intermittent fasting found the same effect when people fasted for 12 hours a day for one month.
Its important to note that both of these studies while illuminating, used a rather small test subject group, and therefore more broad range research is necessary.

Many people have turned to fasting as a way to help maintain a healthy weight and boost their metabolism. Fasting achieves this desired effect through a few avenues.
First off, fasting can help restrict caloric intake, when practiced appropriately (refer to the tips in the above section for safe fasting technique). Calories are a unit that measures energy, specifically the energy content of foods and beverages that we consume. While your body needs calories in order to function properly, energize, and maintain overall health, fasting can help certain people manage calorie intake.
Yet, while caloric restriction may be part of the puzzle, the bigger piece lies within the benefits to your metabolism.
When it comes to short-term fasting, research has discovered that this practice may boost metabolism by increasing levels of the neurotransmitter norepinephrine, which could enhance healthy weight management. Another study review found that whole-day fasting could reduce body weight by up to 9 [percent] and significantly decrease body fat over 12 24 weeks. For those practicing intermittent fasting, a review found that intermittent fasting over 312 weeks was as effective in inducing weight loss as continuous calorie restriction and decreased body weight and fat mass by up to 8% and 16% respectively.
