Your Ultimate Guide To Fasting

New research on fasting challenges traditional nutrition advice, highlighting its benefits for health and longevity. Fasting, when done correctly, can reduce disease risk factors and promote cellular regeneration without slowing metabolism or causing weight rebound. The most recent study into fasting even suggests that fast-mimicking diets can reverse ageing by up to 2.5 years. There are many different versions of fasting diets, so there may be one to suit your lifestyle, though fasting is not right for everyone. Time Restricted Eating (TRE) limits food intake to an eight-hour (or shorter) window daily, aiding in weight loss and metabolic health. Intermittent fasting alternates fasting with normal eating, showing effectiveness in weight loss and insulin sensitivity. Periodic fasting involves prolonged water-only fasts for health benefits like autophagy and stem cell production. Fasting Mimicking Diets offer fasting benefits with specially designed plant-based meals. It is recommended to work with an expert before making significant changes to your diet, and to find the right plan for you. Here, we’ll run through all the different forms of fasting diets, and their effectiveness as a weight loss strategy.

WHAT IS FASTING?

We’re now learning that going for extended periods of time without food can provide a wide range of benefits. Fasting has been shown to promote health and longevity by reducing numerous disease risk factors and promoting cellular regeneration. Fasting for weight loss is also growing in popularity. When carried out in the right way, fasting will not automatically result in a reduced metabolic rate or rebound weight gain as once believed.

There are various approaches to fasting, so what are they? What are the proven health benefits? And are there any downsides? Here’s your essential guide to fasting…

WHAT’S THE LATEST RESEARCH INTO FASTING?

Fast Mimicking Diets have been in the news for their efficacy and potential to reduce biological ageing. The study on fasting-mimicking diets (FMD) revealed significant health benefits, including reduced insulin resistance, liver fat, inflammation, and aging markers. This diet involves consuming formulated food with controlled dietary macros for 5 days followed by normal eating for 25 days monthly. While effective, this fasting-like diet is not suitable for everyone, such as pregnant individuals and older adults. Three cycles of FMD were shown to improve various health markers and reduce biological aging by an average of 2.5 years.

WHAT ARE THE DIFFERENT FASTING DIETS?

TIME RESTRICTED EATING

WHAT IS IT?

Time restricted eating (TRE) involves restricting food intake to a limited period of time during the day, typically eight hours. This is often referred to as the ’16:8 Diet’. TRE is designed to be practiced daily, on an on-going basis.

IS THERE ANY EVIDENCE?

Research has demonstrated time restricted eating to be helpful for preventing and addressing obesity and metabolic disorders, including type 2 diabetes. In one study, overweight individuals had their daily eating window reduced from over 14 hours, to between 10–11 hours daily for 16 weeks. Their body weight reduced and they reported being energetic with improved sleep.

WHAT ARE THE PROS?

Time restricted eating doesn’t require calorie restriction or going for extended periods of time without food. It particularly suits individuals who don’t have a natural desire to eat breakfast.

WHAT ARE THE CONS?

Those who are used to eating breakfast first thing may experience hunger initially, if they choose to delay eating in the morning. It can take some adapting to for people who graze throughout the day, from morning until night.

HOW TO DO IT

Consume all food during an eight hour period every day. For example, if you start your breakfast at 11am, make sure you’ve finished dinner by 7pm. Between 7pm and 11am, consume only water.

Some individuals choose to skip either breakfast or dinner, eating just two substantial meals per day. Others consume three meals per day within a shorter timeframe than usual.

Consider daily routine and personal preferences in order to find a timeframe that works for you.

INTERMITTENT FASTING

WHAT IS IT?

Intermittent fasting involves alternating 24 hour periods of fasting with periods of eating normally. Fast days typically involve either consuming water only, or significant calorie restriction. The 5:2 or ‘fast diet’ approach is the most well known form of intermittent fasting.

IS THERE ANY EVIDENCE?

Studies have found that intermittent fasting was as effective as continuous calorie restriction for improving weight loss, insulin sensitivity and other health markers.

WHAT ARE THE PROS?

If adopting the 5:2 diet, the person fasting needs to understand the calorific values of the foods they are consuming. This often results in an increased awareness and positively influences food choices on non fasting days.

The individual can choose which days to fast in order to allow this method to work around their lifestyle.

WHAT ARE THE CONS?

When restricting food intake, you’re also limiting the opportunity to consume essential nutrients such as vitamins, minerals, antioxidants, essential fats and fibre. It’s important to ensure that the general diet is as nutrient dense as possible. It’s wise to consider taking a good quality multivitamin and omega 3 supplement.

HOW TO DO IT

There are two primary methods of intermittent fasting. One method involves fasting completely, consuming nothing except water for 24-hours, on one or two non-consecutive days a week.

The most common method is the 5:2 diet approach. This involves consuming only 500 calories for women, or 600 calories for men calories per day, on two non-consecutive days per week. There is no restriction on food intake for the remaining days of the week.

PERIODIC FASTING

WHAT IS IT?

Traditional periodic fasting involves consuming nothing but water for a period of several days. Leading experts in the field believe that in order to experience the full range of health benefits that fasting can provide, prolonged fasts should be carried out for more than three to four days.

IS THERE ANY EVIDENCE?

Prolonged fasting has been shown to induce autophagy – a process that helps to maintain healthy cellular function. During autophagy cells repair, regenerate and rid themselves of debris. Prolonged fasts also promote stem cell generation.

Water only fasts induce ketosis during which the body switches over from using glucose (from carbohydrates) as a primary energy source, to burning stored body fat. This can be a very effective way to reduce excess body fat and reduce risk factors associated with carrying excess weight.

WHAT ARE THE PROS?

Periodic fasting induces autophagy and promotes stem cell production that less strict methods of fasting may not.

WHAT ARE THE CONS?

There are potential contraindications with medical conditions such as diabetes and heart conditions. Fasting for long periods of time carries the risk of low blood sugar and fainting. It’s not uncommon for individuals to experience side effects such as headaches. Extended water only fasts should be carried out under expert supervision.

HOW TO DO IT

A healthcare professional should be consulted before doing a ‘water only’ fast, as it can cause harm if done incorrectly. Ideally blood tests should be run in order to rule out any underlying health issues.

If fasting for longer the five days this should then be supervised by an experienced professional. Plan on drinking 2-3 litres of water every day whilst you’re fasting, but space this out over the day. Avoid strenuous exercise.

FASTING MIMICKING DIETS

WHAT IS IT?

A concept developed by Professor Valter Longo and researchers at the University of Southern California, who have carried out extensive research into periodic fasting. Fasting mimicking diets (FMDs) provide the benefits of water only fasting but with a specially designed, plant based diet plan that does not trigger nutrient sensing pathways.

IS THERE ANY EVIDENCE?

FMDs are the result of two decades of research and millions of dollars of Federal funding. In studies, FMDs reduced risk factors for ageing and diseases including diabetes, cardiovascular disease and cancer. Benefits include reduced visceral fat and levels of systemic inflammation, stem cell generation and autophagy.

WHAT ARE THE PROS?

Fasting mimicking diets provide the health and cellular regeneration benefits of periodic fasting but without having to give up food altogether. For many individuals, a programme which allows food can seem less daunting compared with consuming water alone for several days. Compared with periodic water only fasting there is reduced risk of certain contraindications.

The provision of specifically designed plant based meals means that the body still receives essential nutrients whilst remaining in a fasted state.

WHAT ARE THE CONS?

As with water only fasting, it’s important to make sure that the individual has no medical contraindications. FMDs cannot be done by individuals who are allergic to the ingredients in the programme which include nuts and soya.

HOW TO DO IT

For healthy individuals it is recommended that three FMD cycles are completed over three months initially, with 25 days off in-between cycles. After the initial three cycles, it is recommended that three cycles are completed per year on an on-going basis.

ProLon is the world’s first fasting mimicking diet. The five day diet plan comes simply packaged, including plant-based energy bars, soups and a variety of snacks, drinks and supplements. These are all carefully chosen to be convenient and have minimal disruption on daily life.

It is important to note that fasting is not right for everyone. Anyone with an active infection or disease, a history of syncope (fainting), those taking regular medication and pregnant women should not fast unless specifically recommended to by a qualified and experienced practitioner. Although research has demonstrated that fasting can help improve blood sugar regulation, fasting should not be recommended to medicated diabetics due to the risk of blood sugar levels dropping too low. Fasting is not recommend for anyone with an eating disorder.

HOW MUCH IS PROLON?

 The FMD costs £199 per five day cycle or £189 per cycle if you subscribe.
