The Potential Benefits of Two-Days-in-a-Week Fasting Diet

Scientists have discovered that two-days-in-a-week fasting diet has the potential to help people lose weight. Besides weight loss, 5:2 fasting has been found to have more than only weight loss benefits. This is according Michael Mosley, a trained physician and BBC medical journalist.

Fasting diet – more than only weight loss benefits.

A fasting diet seems to be a grueling task for you?

Indeed, the thought of fasting sound something unpleasant even to Dr. Mosley when he embarked on the journey to presenting a new diet documentary on intermittent fasting. He was forced to try the idea when his doctor said that he stood high chances of coming down with some heart disease and high blood pressure. Instead of going the medication way, he chose to give the program a try. As result, he requested BBC to use him as a guinea pig for the novel scientific experiment called Mosley fast diet.

Scientists concur that eating less has the capacity to tend human life span.  There are a few different intermittent fasting methods, but you can simply restrict your daily eating to a specific time frame, ideally a window of four to eight hours twice a week.

This means no calories at all during your non-eating window, but you can drink (and you should) water, tea, and coffee, but without any milk or sugar added. Mosley took two meals on his fasting days, but you can one can also take one meal instead, as it increases the healthy effect on your cells.

Mosley rules that if women take 500 calories and men 600 calories on the fasting 2 days diet (1/4 of your normal calories), they are going to lose weight in a reliably steady manner. There are no restrictions on the non-fasting days. He says that the most beautiful thing with his personal experiment was that he did not find himself overeating on the feed days.

What are the other beneficial effects of the fasting diet beside weight loss?

The major benefits are a decrease in Insulin and in IGF-1 (an Insulin-like growth factor), a better Cholesterol ratio, as well as an increase in cell repair and regeneration.

  1. I’m sure you heard of Insulin and how it relates to diabetes, so I don´t go into that now. But keeping your insulin levels under control is a major objective for long-term health and weight control. During fasting periods Insulin is dramatically reduced.


  1. IGF-1 is a protein produced by the liver and leads to accelerated ageing; high levels are believed to increase the risks of colorectal, breast and prostate cancer significantly, while low levels reduce the risk. In laboratory animal tests, lower levels of IGF-1, induced by calorie restriction, have been shown to slow down the ageing process. According to Prof. Valter Longo of the USC Davis School of Gerontology a reduced intake of proteins has a similar effect.


  1. Cell repair – according to Prof. Valter Longo : “When you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged.” In the fasting period a number of DNA repair genes are switched on, but getting this process started needs about a food-free period of at least 12 to 16 hours. In other words, the longer your food-free period lasts the more repair will be done.


  1. The Cholesterol ratio improves, which means a higher HDL and lower LDL (bad cholesterol) levels.

This novel discovery has placed intermittent fasting among one of the sure-fire ways to lose weight and increase health naturally.

With the 2 5 fast diet, one does not really need to restrain their appetite continuously. Despite how much one eats on the non-fast days, this kind of fasting has been found to be quite healthy.

However, you should first seek the nod of a medical practitioner before you embark on the two day fast diet, as it is not recommended if you are pregnant or diabetic on medication.

When starting the fasting diet myself, I had some weird fear about feeling hungry. But well it’s not the end of the world, keeping busy helps, sipping hot tea helps and also the certainty of a non-restrictive day ahead.
