Fasting is a common practice and not eating anything the whole day is done by many people but is it safe and what happens when our body doesn’t get its daily intake of food? the practice of not eating for 24 hours is called intermittent fasting. Some people skip breakfast, some skip lunch, and many fast every other day.
Fasting for a whole day is safe but it can also be dangerous. It’s important to know the pros and cons of fasting if you are thinking about doing this. You need the calories in food to keep you going the whole day and keeping that away from your body the whole day will have positives as well as negatives.
The benefits of fasting
Fasting for a whole day can help you lose weight and in some cases, it has been shown to be as good as a long-term diet. It will help the kidneys flush out toxins from your body, thus reducing the risk of kidney disease. And it can also have an effect on inflammation which is linked with heart disease, diabetes, and some cancers. And if you are trying to improve your heart health, fasting can lower cholesterol levels in the body which is linked with a reduction of the risk for heart disease.
When you don’t eat for a whole day, you can become ketotic and this has been shown to be beneficial in some cases.
The dangers of fasting
Even though fasting is safe for most people when done the right way, there are some risks with doing it. The longer you’re fasting, the more risk you have for developing gallstones. This has been reported for a few people who have fasted for a whole day or longer. If you are diabetic, fasting can affect your blood sugar levels and it may be dangerous if you take insulin.
People with low blood pressure and those taking certain medications should not fast and if you are considering fasting, make sure you first consult with your doctor.
what happens when you fast for a whole day?
The first eight hours are actually easy as your body will be digesting the food you have eaten previously. Your body still has no idea that you will not be eating again, so it will use the stored glucose as energy. when the time for breakfast passes, your body will have to get energy from breaking down glycogen in the liver. at that point, you might feel a little dizzy and hungry but it will pass. after 12 hours of fasting, your body will start to break down fat stores. when this happens your ketone level increases and urine excretion will increase. When this happens, it’s important to make sure not to overdo it. you should only fast the right amount of time. After 16 hours of fasting, you will start to feel tired and drained.
The impact of fasting on your body
You might lose weight in the short term when you fast for 24 hours but this won’t last long. Your body goes back to normal after one or two days. The same is true with intermittent fasting where many people report weight loss but after a few weeks, the weight returns and you might gain more than what you lost. The ketogenic diet, which is when you limit your carbohydrates and eat mostly fat, has been shown to have longer-lasting benefits. In low carb diets, for example, people have reported losing 2kg in one month compared to other diets where they only lose 0.5kg. you can get in-depth knowledge about calories in some of the best calorie sites on the net.
The impact of fasting on your brain
Studies show that intermittent fasting can improve cognitive function and memory which is done by improving cell function in the hippocampus of the brain. It has also been shown to increase levels of BDNF which protects neurons against toxicity, stabilizes moods, decreases harmful beta-amyloid proteins in the brain, and prevents the degeneration of neurons.
Fasting improves learning capacity by stimulating synaptic plasticity which is a change in the chemistry of the brain that takes place when you learn something new. Long-term ketosis also helps to protect against Alzheimer’s disease by preventing cell damage which is done by high blood sugar levels. So many studies have shown the positive effects of fasting on the brain. And this is done without weight loss which means you can get these benefits even if you don’t lose weight.
