What Is Intermittent Fasting

First and foremost, intermittent fasting can lead to weight loss if done correctly. This is because when you fast, your body starts burning fat instead of carbs and proteins for energy.

However, if you’re not careful about your diet while fasting, you may gain weight back once you begin eating again. To avoid this, make sure to follow an overall healthy diet while intermittent fasting and include plenty of fruits and vegetables in your meals.

Another common intermittent fasting side effect is an increase in blood sugar levels. When you don’t eat for several hours each day, your body will start releasing stored glucose from your liver and muscles. This can lead to feelings of hunger and cravings shortly after breakfast or lunchtime, but be sure to eat small amounts throughout the day instead of large meals.

Finally, intermittent fasting can also cause difficulty sleeping at night. Make sure to get enough sleep each night during your fasted period by following a relaxing bedtime routine and avoiding caffeine before bed.

Choosing your intermittent fasting plan

Another intermittent fasting side effect is that people may become dehydrated. When you fast, your kidneys work extra hard to conserve water and help flush out toxins from the body. If you are not drinking enough fluids while fasting, this can lead to dehydration.

Another intermittent fasting side effect is that people may experience headaches. This is likely due to the fact that when you fast, your brain is not getting the same amount of glucose it is used to getting. When blood sugar levels drop too low, the brain tries to get its energy from other sources like protein synthesis which can lead to headaches.

Irritability and other mood changes

Irritability and other mood changes are a common side effect of intermittent fasting. People who follow an intermittent fasting schedule may experience increased irritability and mood change as their body switches from using glucose to fat for energy. This can be temporary or long-term, depending on the person’s condition and how much they restrict their caloric intake. Some people find that intermittent fasting helps them lose weight or keep their weight off, while others notice no improvements. If you’re struggling with mood changes or irritability, it’s important to talk to your doctor about your regimen and make sure you’re taking in enough nutrients and protein to support healthy brain function.

Fatigue and low energy

Fatigue and low energy are common intermittent fasting side effects. These symptoms can be caused by a lack of energy or fatigue, as well as a decrease in the number of hours you can sleep at night. If you experience these side effects, make sure to drink plenty of fluids and rest to restore your energy and sleep patterns.

Sleep disturbances

In fact, one study found that people who intermittent fasted for 16 hours or more experienced disrupted sleep patterns. This could include difficulty falling asleep, staying asleep, and experiencing frequent awakenings.
