Intermittent fasting (IF) is a popular strategy for weight loss and improving overall health. Many individuals opt for intermittent fasting as a straightforward solution for weight loss. Restricting eating periods, it simplifies meal planning and eliminates the need for tedious calorie counting. It involves cycles of eating and fasting with common methods including 16:8 (16 hours fasting, 8 hours eating) and 5:2 (five days of normal eating, two days of reduced intake). Its benefits often include improved metabolic function, reduced inflammation and weight loss. However, IF is not suitable for everyone.

In a conversation with Jagran English, Dr. Hatinder Jeet Singh Sethi, Additional Director - Internal Medicine, Fortis Manesar listed groups of people who should avoid intermittent fasting.

Who Should Avoid Intermittent Fasting?

Pregnant or breastfeeding women- Increased nutrient demands may not be met during fasting.

Individuals with eating disorders- Fasting may trigger or worsen disordered eating habits.

People with diabetes or blood sugar instability- Fasting can cause dangerous drops in blood sugar, especially if medications are involved.
