Here’s How To Do Intermittent Fasting Safely & Sustainably

Clinical nutritionist, Gabrielle Newman gives us the lowdown on Intermittent Fasting

First things first, what is it??

While fasting normally means going without any food for a period of time, intermittent fasting is a modern, easier approach where you stop eating for a part of each day or restrict your calorie intake for a few days each week.

There are two main methods we incorporate at The Fast 800, which can be utilised together depending on your lifestyle:

● a 5:2 approach where you restrict your calorie intake to 800 calories for two days a week, and eat a healthy diet for the other five days; and

● Time Restricted Eating (TRE) which encourages you to extend your normal nighttime ‘fast’ by eating an early dinner, or skipping breakfast, to condense your eating period into an eight, ten or 12-hour window.

What Are Some Benefits Of Intermittent Fasting?

Short-term fasting activates a process within the body called ‘autophagy’ whereby dead, diseased or worn-out cells are broken down, consumed and excreted (autophagy means ‘self-eat’) to make way for the shiny new cells that keep us young.

If following a 5:2 approach, with the incorporation of a lower carb Mediterranean-style diet and two fasting days of only 800 calories, you can expect:

● A greater loss of fat than on a conventional calorie restricted diet

● Reduced inflammation

● Reduced blood pressure

● Reduced blood sugars and insulin resistance

● A nutritious, high-fibre diet which can improve bowel function

● Possible improvements in brain function and mood

● Bolstered immunity

So, What Should Be On the Menu?

Ultimately, it comes down to balance of good quality protein, fibre and healthy fats, which is essentially the Mediterranean Diet. The good news is, whether you incorporate intermittent fasting or not, a low carb Mediterranean Diet has unique power not just to restore your body’s ability to reach its ideal weight and stay there, but also to cut your risk of serious disease. It doesn’t come from a place of restriction but rather it’s about eating more of the right foods. Not only will these foods keep you feeling full, they offer important nutrients and health benefits, and taste delicious.

● Start the day with eggs: Boiled, poached, scrambled or as an omelette – they’ll keep you feeling fuller for longer compared to cereal or toast. Delicious with greens and parmesan or smoked salmon and a sprinkle of chill.

● Full-fat yoghurt is good: Choose a plain Greek-style yoghurt and add berries, like blackberries, strawberries or blueberries for flavour.

● Have high-quality proteins: Oily fish, prawns, chicken, turkey, pork, beef and, of course, eggs. Other protein-rich foods include beans, especially edamame beans, dairy and nuts and seeds. Processed meats (bacon, salami, polony) should be eaten sparingly and in small quantities.

Gabrielle suggests eating coloured veg

● Eat more healthy fats and oils: Along with oily fish (salmon, tuna, mackerel), consume more extra virgin olive oil. A splash makes vegetables taste better and improves the absorption of fat-soluble vitamins. Use olive, or coconut oil for cooking. Avocado is another great source of healthy fats that will keep you feeling full and satiated.

● Eat plenty of different coloured veg: From dark leafy greens to bright-red and yellow capsicum. More variety of colours means more variety of nutrients. Adding a collagen powder to your hot or cold drinks during the day will give an extra boost of Vitamin C. The Collagen Co Unflavoured Collagen Powder is perfect for this if you're after a flavourless addition to water or coffee.

● Fibre is key: A low carb Mediterranean diet does not mean no carbs at all. Not only is this very hard to achieve but can be detrimental. Therefore, complex carbs and fibre are still important and can easily be gained from vegetables, legumes and whole grains.

● Dairy products are back in: Recent research has found that these do not cause diabetes. They are a good source of calcium and protein. Dairy helps you feel fuller for longer. Choose full-fat but eat in moderation as it can be high in calories. A scattering of parmesan can be used on baked vegetables to add flavour and protein.

● Nuts are also included: They provide a good source of protein, minerals and vitamins, contain healthy fats and have a high fibre content. You nibble them, chuck them in salad or stews. They make a good low carb alternative to flour for baking by using almond or coconut flour.

● A little bit of dark chocolate and red wine here and there is fine! Research actually shows that resveratrol, a compound present in red wine (as well as in blueberries, cranberries and cocoa) can contribute to the health benefits of the Mediterranean Diet. So, if you would like to complement your recipes with the occasional glass of red or piece of dark chocolate, you can. Just be more mindful on fasting days as the calories can be significant.
