A Beginner's Guide to Intermittent Fasting

Understanding Intermittent Fasting

Fasting is abstaining from eating any food for a particular period consciously. It can have various health benefits, such as weight loss, improved heart and brain functioning, and better blood sugar control, among others. In the case of intermittent fasting, there is a set pattern of eating and fasting. While there is a lack of concrete scientific evidence to validate the benefits of intermittent fasting in cancer care, there have been multiple observations where intermittent fasting has helped cancer patients in weight loss and controlling blood sugar levels. Intermittent fasting is known to help people lose weight and improve the metabolism of the body. It also helps in reducing oxidative stress and allowing the body to heal internally. There are several types of intermittent fasting. Some of the most popular methods are:

The 16:8 method

The 16:8 is one of the most popular methods of fasting regimen. In this method, a person can consume food for eight hours a day and abstain from food during the remaining sixteen hours.

The 5:2 diet

In this method, it is not as per the hours but the days. The individual can consume unrestricted calories, (without a calorie limit) five days a week, and on the remaining two days, they must reduce the calorie to one-quarter of their regular intake.

Common Questions Patients Ask

1. Can intermittent fasting help me lose weight?

Intermittent fasting can indeed help in losing weight. It is mainly because the patients abstain from food for a long period, they consume less number of calories which aids in weight loss.

2. What are the benefits of intermittent fasting for cancer patients?

Some aspects, such as weight loss and controlling blood sugar levels, can also aid cancer patients during their treatments. However, cancer patients are advised to consult with an Onco-nutritionist or doctor before taking any kind of fast as it can increase the risk of malnutrition and weakness in some cases.

3. Can intermittent fasting cause any adverse reactions?

The adverse effects of intermittent fasting can differ from person to person. If a person who is physically weak fasts for sixteen hours a day, that person might face dizziness and tiredness from prolonged fasting, while the same fast may not affect physically fit people.
