Reply to comment by not_cinderella in Intermittent Fasting significantly reduced systolic blood pressure (SBP), but not diastolic blood pressure (DBP). The effects are likely due to weight loss. by glawgii

When your body enters a fasting state it will begin a process called Autophagy, the process of cleaning up old and damaged cells in your body

This process has a number of beneficial long term effects such as lowering cancer risks, elimination of latent viruses and pathogens hiding in older cells, triggering stem cell production, etc.

Another study about this effect, though this is using longer fasting cycles the benefits still apply for IF

>The study has major implications for healthier aging, in which immune system decline contributes to increased susceptibility to disease as people age. By outlining how prolonged fasting cycles — periods of no food for two to four days at a time over the course of six months — kill older and damaged immune cells and generate new ones, the research also has implications for chemotherapy tolerance and for those with a wide range of immune system deficiencies, including autoimmunity disorders

It’s hard to wrap my head around how not eating for 4 days could be healthy, but that’s probably m personal struggle with disordered eating coming in. Thanks for the info.

Going that long is extreme and should definitely be medically supervised to make sure you're getting the correct nutrition supplements. People do go that long on a routine as well but they have to build up to it and be very careful coming out of it to avoid refeeding syndrome

In this context they're looking at the extreme specifically for treating cancer patients
