36-40 Hours Intermittent Fasting Event

36-40 Hours Intermittent Fasting Protocol, Also Known As “Alternate Day Fasting”

banner link to fasting home page

This involves fasting for the entire day. For example, if you eat dinner on day 1, you would fast for all of day 2 and not eat again until breakfast on day 3. This is generally 36 hours of fasting. This provides a more powerful weight loss benefit. The other great benefit is that it avoids the temptation to overeat dinner on day 2.


For me 40 hours IF works the best. It means that I stop eating at 9 pm, fast the next day and then start eating again at 1 pm (lunch) on day 2.

Of course, everyone can adjust the times to their needs and there is not a set rule for it. Just pick the times that work best for you.

Please, fill in the form below to take part in 36-40 hours IF Protocol and you will also receive tips and support via email and live chat.

Who should NOT fast?

You should not do intermittent fasting if you are:

  • Underweight (BMI < 18.5)

  • Pregnant – you need extra nutrients for your child.

  • Breastfeeding – you need extra nutrients for your child.

  • A child under 18 – you need extra nutrients to grow.

You can fast, but may need supervision, under these conditions:

  • If you have diabetes mellitus – type 1 or type 2.

  • Taking prescription medication.

  • You have gout or high uric acid.

Please, let us know what type of fast are you doing and start date.
