In recent years, there has been considerable public, media and commercial interest in the potential benefits of various forms of intermittent fasting. These include time-restricted eating, ‘5:2’ diet or alternate-day fasting-mimicking regimes.

There appears to be significant hype in the media concerning the health and weight-loss benefits of such regimes, but does the evidence support such hype? Are some regimes clearly more effective and beneficial than others? Could there be negative consequences to these approaches to intermittent fasting?

To address these important questions, this webinar brings together diverse experts including dietitians, nutritionists, sports physiologists, psychologists, neuroscientists and physicians to present and discuss recent scientific evidence on intermittent fasting. 

Join us for an update on the efficacy of forms of intermittent fasting on weight loss and other potential health benefits, including blood glucose, lipids, and brain function.

During this session, participants will be able to:

  • Know the extent to which evidence supports intermittent fasting as an alternative to continuous caloric restriction for weight loss and other health benefits
  • Understand how different forms of intermittent fasting such as time-restricted eating or alternate day differ in their effects and outcomes
  • Be aware of the evidence for metabolic changes, including interactions with exercise, and impacts on appetite, that may occur when undertaking intermittent fasting
  • Understand who may be more likely to adhere to intermittent fasting regimes
  • Be aware of any potential negative consequences of forms of intermittent fasting

This webinar is available for on-demand viewing. The webinar recording will be available for registered delegates up to 30 days after the live webinar broadcast via Zoom. The link will be sent 24 hours after the webinar takes place.

A CPD certificate with CPD credit will be issued to those joining the webinar live as well as those who watch the recording afterwards. Certificates will be issued 7 days after the webinar to those who watch it live and after 30 days for those that watch the recording.
