There’s a new beauty product in town set to lengthen your lifespan. It’s a trend that seems to be grabbing the attention of those wanting to live longer and healthier lives.
We all want to avoid aging, but in truth, it is undeniable that we will age and eventually leave this earth.
So how do you get to eat less and live longer? This in itself is a contradiction as we need to eat to stay alive.
What exactly is intermittent fasting?
Intermittent fasting is the practice of eating certain days at a specific time.
There are several forms of intermittent fasting or IF :
- Eating is done only a few days a week during specific hours; eg. 5 days a week between 5 pm – 8 pm.
- Eating is done every other day, not time specific.
- Eating is done throughout the day but does not exceed daily calories allowed.
The primary focus of intermittent fasting is that all to familiar and magical word that you either love or hate – calories.
If this still isn’t making any sense to you join the club; starvation should never be an option. But here’s the thing in order to adequately research the topic, I decided to try this technique for a full 24 hrs.
I chose to fast from 6 am – 6 pm. I did drink water during my fasting period but only to quench my thirst and not as a means to trick my body into thinking that it had been fed.
What happened was that my brain and gut formed an unholy alliance and persisted in tormenting me the entire time until I actually ate. Supper was my normal portion and I had no desire to eat anything extra once my hunger had been sated.
So what does this mean exactly? You will need to find a system that works for you. It is not a cheap Chinese reproduction “one size fits all” type of solution. One couple, in particular, has found that they fast the entire day up until 5 pm and then they eat as much as they want until they go to bed.
Essentially, intermittent fasting is not watching what you eat, or how much you eat, but rather controlling when you eat. The WHAT and HOW have turned into WHEN (because timing is everything).
Jimmy Kimmel, Hugh Jackman and the 5:2 Diet
It always astounds me at the reaction my body has to the word diet, it is completely unfounded. What does the 5:2 diet; Jimmy Kimmel and Hugh Jackman have in common?
Both celebs have credited the 5:2 diet to astounding weight loss results. Last year Jimmy Kimmel told Men’s Journal that he had managed to lose a healthy amount of weight by simply following the calorie controlled diet.
Whilst Hugh Jackman used the intermittent fasting to get his body ready for his Wolverine role in 2013. He fasted for a full 16 hours and then ate within an 8-hour window period; resulting in some serious abs!
It is not just celebs who are singing IF’s praises, even a neuroscientist from the National Institute on Aging situated in Maryland has revealed to the NY Times that he only eats during a six-hour period starting in the afternoon. Which means he does not eat breakfast or lunch – so there goes the theory that breakfast is the most important meal of the day.
So here are the questions on everyone’s lips – Why fast? What does it do?
Researchers have been studying fasting on animals (mainly mice) for quite some time and the results certainly show that there is merit to the claim that it could potentially prolong or slow down aging.
What Happens to Your Body When You Fast
Scientific research has shown that when you fast your body reacts in the following way:
- During fasting cells undergo mild stress – while stress may not be the ideal synopsis, in this instance, it is a positive.
- In turn, the cells in the body respond and adapt by enhancing the body’s coping mechanisms; the same as when resisting a disease.
- In fact, scientists reveal that cells respond in a similar way to intermittent fasting as it does to exercise.
- Fasting for a period of 10-16 hours will cause the body to tap into its fat stores, which releases ketones (fatty acids) into the bloodstream.
What are the Benefits
Research has once again shown that fasting may actually benefit both the brain and the body.
- Remember those fatty acids or ketones – when released into the bloodstream they have been proven to protect learning functionality as well as memory and slow down brain-related diseases.
- It has also shown to reduce oxidative stress and improve disease biomarkers.
- A decrease in inflammation; improvements in symptoms related to asthma sufferers.
- Increase in “quality-of-life” markers.
Considering all the above scientific information, it may be safe to say that fasting works on a cellular level. The Annual Review of Nutrition noted that intermittent fasting may be a “viable means” of increasing one’s overall health.
The Do’s And Don’ts Of Intermittent Fasting
Naturally, the dilemma with IF is that it walks a fine line between being healthy and binge eating. If you follow these simple guidelines then you will stay on the safe side of this line:
- Do maintain a healthy diet whereby you are still eating good portions of good food. Don’t eat nothing for long periods of time and then “pig out” on unhealthy foods such as fast foods.
- Do pick one day of the week to indulge yourself with whatever you are craving. Don’t overindulge even on your “cheat day”. Rather still maintain a healthy balance.
- Do seek medical advice if you are unsure or already have a pre-existing medical condition. Don’t just assume that you can cope with long fasting periods.
Okay to get to the real reason why you are reading this article – how does intermittent fasting slow down aging? The theory in a “calorie controlled time shell”, so to speak, is as follows:
“The fasting phase kills off weaker cells which in turn activates or turns on stem cells (basic body instinct kicks in). Stem cells turned on, in turn, means, regeneration of cells throughout the body. The result is younger newer cells. This means, in turn, a younger; more energetic you.” This is according to Valter Longo, Ph.D.
This may all sound too good to be true; but that age-old saying – “Everything in moderation”……..
Scientists’ main concern about IF is that it will end up being abused as a “Fad Diet” and in the end result in harming individuals.
But, if done in a controlled and healthy way certainly has a long list of benefits, that when combined correctly may be one you can use for eternity!
