Intermittent fasting (IF) has become a popular trend in the health and fitness world. It involves alternating periods of fasting and eating. While many people have reported positive effects from IF, some have claimed that it makes them feel tired. In this article, we will explore if there is any truth to this claim.

What is Intermittent Fasting?

Intermittent fasting is a pattern of eating that involves alternating periods of fasting and eating. There are several different methods of IF, but the most common ones are:

1. 16/8 Method: Also known as the Leangains method, this involves fasting for 16 hours and eating within an 8-hour window.

2. 5:2 Method: This involves eating normally for five days and limiting calorie intake to 500-600 calories for two non-consecutive days.

3. Eat-Stop-Eat Method: This involves fasting for 24 hours once or twice a week.

Intermittent fasting has been shown to have numerous health benefits, including weight loss, improved insulin sensitivity, and reduced inflammation.

Does Intermittent Fasting Make You Tired?

Many people have claimed that intermittent fasting makes them feel tired, especially during the initial phase of starting the diet. This is because the body is adapting to the new eating pattern and is not receiving food when it is used to.

However, studies have shown that intermittent fasting does not cause fatigue in the long term. In fact, it has been found to have the opposite effect, improving energy levels and reducing fatigue.

Benefits of Intermittent Fasting

Aside from weight loss and improved insulin sensitivity, intermittent fasting has several other benefits:

1. Improved Brain Function: Intermittent fasting has been shown to increase the production of brain-derived neurotrophic factor (BDNF), which improves brain function and protects against neurological diseases.

2. Reduced Inflammation: Intermittent fasting has been found to reduce inflammation in the body, which can lead to a lower risk of chronic diseases such as heart disease and cancer.

3. Anti-Aging: Intermittent fasting has been shown to increase lifespan and delay the onset of age-related diseases.

Intermittent Fasting vs Other Diets

Intermittent fasting has several advantages over other diets, including:

1. No Calorie Counting: Unlike other diets that require you to count calories, intermittent fasting only requires you to limit your eating to specific times of the day.

2. No Food Restrictions: You can eat whatever you want during your eating window, making it easier to stick to the diet.

3. Improved Insulin Sensitivity: Intermittent fasting has been found to improve insulin sensitivity more than other diets, which can lead to better blood sugar control and a lower risk of type 2 diabetes.

Conclusion

Intermittent fasting does not make you tired in the long term. While some people may experience fatigue during the initial phase of starting the diet, this is not a permanent effect. Intermittent fasting has numerous health benefits and is a viable option for those looking to improve their health and lose weight.
