Most adults eat for more than 15 hours a day, with a tendency for late-night eating. This causes “metabolic jet lag” – More weight gain, more insulin resistance, more sleep issue, less energy.
When you eat is paramount for disease prevention & chronic disease issue
The time you eat has a direct effect on your circadian rhythms so it affects the way your body processes your meal. The same caloric intake at dinner is more fattening than if consumed at breakfast.
The time between two feeds is also changing your metabolic results:
– In a fed state you use sugar as the main source of energy, switching off the use of fat.
– 4 to 12 hours after eating you enter the post-absorptive state. You start using glycogen, your stored glucose, and some circulating fatty acid.
– From 12 to 14 hours post-meal, you flip your metabolic switch and start to run on ketone bodies, essentially produced from stored fatty acids.
There is a lot of literature to debate at what time this metabolic switch happens post-meal. And most researchers agree that the metabolic switch happens between 12 and 36-hour fasting.
However, the 12 to 16-hour mark is key to initiate healthy longevity without the inconvenience of a full fast.
If you are like me, you may have indulged over the past few months. You may have eaten more treats or simply eat more often.
Now is a great time to flip your metabolic switch.
This metabolic switch is not only about weight loss, it is also about
– Increasing your health span (not only your lifespan),
– Bringing more energy in your body,
– Preventing chronic illnesses,
– Building up muscle,
– Enhancing your memory,
– Improving your resilience.
You name it!
You start to flip your metabolic switch when you stop burning only sugar and circulating fat and start to burn ketone bodies and fatty tissue breakdown. This only happens when the point of negative energy balance is reached. That means when you stop eating long enough.
Why not starting from 12 hours overnight fast now?
Note: Avoid extending your fasting window if you do suffer from hypoglycaemia. Consult your practitioner to be guided towards the diet plan that is the best for you. When you decide to adopt a fasting lifestyle and extend your fasting window, your practitioner will also ensure your nutrient status is optimum to avoid any side-effects.
