6 Side Effects of Intermittent Fasting for Weight Loss

1. You may feel hungry all the time

This is the most common side effect of intermittent fasting. By restricting your eating times, you are reducing your nutrient intake. As a result, you may feel hungry all the time. However, some people may also experience a loss of appetite.

2. Intermittent fasting makes you crave food

When you restrict your food intake and fast during certain times of the day, you will think about food, which leads to cravings. This happens because your body is trying to adjust to the fast. Not to mention, fasting means reducing your calorie intake, which leads to increased stress hormones, hunger hormones, and irritability.

3. You may also have sleep disorders.

Although many studies suggest that intermittent fasting can help you sleep better, in the long term, it can affect REM sleep (which helps improve memory, mood, and learning ability) and also reduce sleep quality.

4. You may have frequent headaches

Dizziness, lightheadedness, and headaches can happen for many reasons. Fasting is one of them. Intermittent fasting can make you feel nauseous, and depending on the duration of the fast, you may also experience headaches.

5. Intermittent fasting can make you constipated

Your body produces acid to digest food but when you don't eat properly, it leads to constipation, which manifests itself in symptoms like less urination, pain while urinating, bloating or heartburn.

6. You may experience hair loss

If you are experiencing hair loss, it could be related to fasting. When we fast, we restrict our calorie intake, so our body does not get enough nutrients, especially B vitamins and protein - important for hair growth.
