Fasting is a time honoured Naturopathic tradition although its not really taught as part of main stream courses anymore. It is still a really useful protocol for some people. There are now a wide range of options with fasting, Juice Fasting, Five Two, Elemental Fasting, Six One and Intermittent Fasting, just to name a few . So what are the current options?
- Juice Fasting – this is usually a shorter fast such as a weekend or a few days and limits your intake to mainly vegetable juices, with a small amount of fruit. It floods your body with nutrition and hydration but can sometimes provoke extreme hunger on day 2. This is often used as a cleanse or weight loss starter and the usual feedback is about half the weight lost is water you do become more concious of what you eat after a juice fast.
- Five Two – a popular adaptation this allows you to eat on an unrestricted based 5 days a week whilst restricting calories to 25% of your normal intake on two of those days. This diet was popularised by Micheal Mosley a few years ago. Ideally to really minimise side effects and benefit from this approach you need to eat nutrient dense foods the other days and ensure that you are getting enough protein and micro-nutrients, such as vitamins and minerals on your non fasting days. Proponents of this approach suggest starting with a 12 hour fast overnight for a few weeks to make it easier.
- Elemental Fasting – this is used therapeutically for a digestive reset for those with serious infections such as parasites or severe SIBO (small intestinal bacterial overgrowth). This fast needs to be run under supervision and comprises shakes which contain adequate amounts of proteins, fats and carbohydrates. The approach is to starve out the problematic bugs.
- Six One – A slight variation to the Five Two it involves completely fasting on one day a week whilst eating normally on the other days.
- Intermittent Fasting – Routinely fasting for twelve hours overnight – basically eating dinner by 7.30 and then breakfasting at 7.30 – can be an effective way to improve your response to glucose and insulin. As part of the Bredesen protocol I studied in 2016 it is recommended as part of a strategy to improve blood sugar as well as specific sensitising nutrients if levels are elevated. In addition its recommended that people with the specific gene for Alzheimer’s known as APO4E fast for up to 16 hours a day. For more information on this protocol see my blog Delaying Alzheimer’s
So what are the benefits reported from fasting ? Micheal Mosley in his 5:2 diet cites three major areas which include weight loss, improved metabolic markers and reduced inflammatory markers such as C Reactive Protein. Research published recently on pubmed is also showing that intermittent fasting or time restricted feeding is proving beneficial for weight loss and metabolic health. (1)
Intermittent Fasting can be a good way to stabilise blood sugars at the early stages of insulin resistance. The 5:2 protocol can be helpful for people who want to lose weight but have trouble sticking to a restrictive diet. Ideally your fast days are separated and you include a small amount of protein in the meals to help stabilise blood sugar.
