16:8 Intermittent Fasting - Group Talk - Week Commencing 8th January 2024.

What is fasting?

Fasting is where we choose not to eat for specific time frames. In fact fasting is a practice that is preformed by many cultures and religions around the world for millenniums.

During the Stoneage and forward to the Great War and the War, people would break bread/dine between dawn till dusk, for example today7th January 2024, Sunrise 08:13 and Sunset 16:04 which is 7hours 51minutes of daylight.

In todays world the ancient practice has and is manipulated to support trends among the health-seekers and dieters, and avocates claim its benefits i.e.:- improved health, long term weight loss and even anti-aging effects.

What does the term 16:8 translate into; 16 hours of fasting i.e. not consuming any food or drink, apart from water, for that interval of time each day, and eating within the 8 hour interval of that day.

16:8 is just one term used to describe the period of fasting alternatively known as 16:8 intermittent fasting. You can practice 16:8/16:8 Intermittent fasting as regularly as fits your lifestyle i.e. once, twice a week or daily. Intermittent fasting is personal to each individual and how you feel each day, to whether you practice it or not.

Intermittent fasting can be flexible, by doing whats known as dirty fasting, which is where you can eat/drink uptp 100kCal in the time frame of practicing fasting.

With out realising we all practice fasting, as none of us eat when we are sleeping however our fasting windows are all different, unless you have studied intermittent fasting you would probably not recognise that you were actually fasting.

How does fasting for 16 hours a day support our health and well-being;

If we constantly eat throughout our waking hours we are constantly topping up our livers source of glycogen, a stored form of glucose energy, gained from carborhydrates. When we stop consuming food the body depletes its glycogen quite quickly. 'Our glycogen stores can take about 10 hours to be used up if we fast' - more quickly if we are active with in the fasting period i.e. workout, Zumba... Once our glycogen stores are used up, our bodies start searching for alternative sources of energy. Its at this point, the body starts to break down stored fats into substances called Ketones to get the job done. This metabolic switch does so much more than meets the bodies energy needs, the switch from using glucose to ketones is a triggering point - it shifts your metabolism from focusing on storage and growth to being all about repair and replace.

In what way can you actively begin observing intermittent fasting. Establish your current fasting window. Then ask yourselfwhy do you eat at these times i.e. routine, hunger, social... Determine what your eating window should be; fitting it into your life/schedule i.e.

  • 9am - 5pm

  • 10am - 6pm

  • 11am - 7pm

  • 12pm - 8pm

  • 1pm - 9pm

You might consider 16:8 to much to start with as a fasting window and prefer to start with 10:14. i.e.

  • 8am - 6pm

  • 9am - 7pm

  • 10am - 8pm

  • 11am - 9pm

and by degrees work your way up to 16:8 if this is something you desire to practice.
