Intermittent Fasting: Benefits, Schedule, and Side Effects

What is intermittent fasting?

Intermittent fasting (IF) is a dieting method that alternates periods of fasting and eating. Unlike traditional diets which focus on what you eat, intermittent fasting focuses on when you eat. Common methods include the 16:8 method, where you fast for 16 hours and eat within an 8-hour window, and the 5:2 method, where you eat normally for five days and then drastically reduce your calorie intake for two consecutive days.

The primary goal of intermittent fasting is to allow the body to use stored fat for energy during fasting periods, which can aid in weight loss and improve metabolic health. In addition, intermittent fasting has been linked to benefits such as improved insulin sensitivity, reduced inflammation, and improved brain health. However, it may not be suitable for everyone and it is important to consult a healthcare professional before starting intermittent fasting, especially for people with underlying health conditions.

What are the types of intermittent fasting?

Intermittent fasting encompasses several popular methods, each varying in the duration and frequency of fasting periods.

• The 16/8 method involves fasting for 16 hours and eating within an 8-hour window daily.
• Another approach, the 5:2 diet, It involves eating normally five days a week and fasting two days a week, with a calorie limit of 500-600 on those days.
• Alternate-day fasting alternates between normal eating and fasting days.
• Additionally, the Eat-Stop-Eat method involves fasting for 24 hours once or twice a week.

These diverse methods cater to different lifestyles and goals, and promotes weight loss, improved metabolic health, and other potential health benefits.

How does intermittent fasting work?

In contrast, when we avoid eating, our insulin levels drops and it encourage fat burning this is the 'fasted state'. By following an intermittent fasting schedule, we cycle between the fed and fasted state which potentially aids weight loss and provides other health benefits.
