8 side effects of intermittent fasting

Shweta Singh

One of the most common side effects is increased hunger and cravings, especially when first starting intermittent fasting. This can make it challenging to adhere to the fasting schedule.

Hunger and Cravings

Some people experience headaches during the initial stages of intermittent fasting. This can be due to dehydration, caffeine withdrawal, or low blood sugar levels.

Headaches

During the adjustment period, you might feel more tired and have lower energy levels as your body adapts to the new eating pattern.

Fatigue and Low Energy

Known as "hanger," the combination of hunger and changes in blood sugar levels can lead to irritability and mood swings.

Mood Swings

Changes in eating patterns can cause digestive problems, such as constipation, bloating, or diarrhea.

Digestive Issues

If not planned properly, intermittent fasting can lead to nutrient deficiencies, particularly if you’re not consuming a balanced diet during eating periods.

Nutrient Deficiencies

Some individuals experience changes in their sleep patterns, including difficulty falling asleep or staying asleep.

Sleep Disturbances

Fasting periods may reduce fluid intake, increasing the risk of dehydration. Symptoms include dry mouth, dizziness, and fatigue.
