Is Fasting Healthful? Dr Sigurdsson Reviews the Evidence

This dude probably went days without food

Dr Axel Sigurdsson published an epic post on intermittent fasting early in 2020. I don’t doubt anything in it although I haven’t yet taken a deep dive into the subject like he has. I touched in it here, here, here, and here. I’ve done some 24-hour fasting myself (here and here).

From the good doctor:

Animal studies suggest that intermittent fasting may have several health benefits. Some of these benefits, in particular, the effects on obesity, type 2 diabetes, and cardiovascular risk factors, have been confirmed in studies on humans.

However, the popularity of intermittent fasting within the general public is in stark contrast with the gaps in evidence on the clinical benefits of this approach.

One response to “Is Fasting Healthful? Dr Sigurdsson Reviews the Evidence

  1. An interesting overview of the different types of fasting.

    However I tend to switch off when I hear the phrase “evidence based support’ given that current scientific methodology is being increasingly questioned. A good example is the debate on the ‘file drawer effect’ which affects many clinical trials. (Steve maybe you could post a blog on the File Drawer Effect”?

    Everyone is different so that makes it fairy difficult to have a one-size-fits-all approach. A common sense approach is to experiment the different forms of fasting and find one (if any) that has appreciable benefits for you.
