Intermittent Fasting – A Simpler Way to Eat

Most of us grew-up hearing ” breakfast is the most important meal of the day” but what if that isn’t the case?

Intermittent fasting has gained a great deal of attention in the past years for the benefits in weight loss, overall healthier-eating, and a way to simplify our lifestyles. Popularized by Martin Berkhan, a nutritional consultant from Leangains, the success of intermittent fasting lies in the fact that it is not a diet but a lifestyle change. Intermittent fasting is divided into two stages, fasting and feeding. The most common type of fasting is the 16:8 known as the Leangains method, consisting of a 16 hour fast followed by an eight hour feeding period with no dietary restrictions.

Fasting and Our Ancestors

Our ancestors did not have the luxuries we have today, they had to hunt their food and this could lead to not finding anything to eat for hours or days at a time. This is the basis of intermittent fasting, going back to our old roots. By allowing our bodies to function as they are intended to do. Studies have shown, intermittent fasting protects against diabetes, obesity, cancers, heart disease, hypertension, neurodegeneration, and many more benefits.

OUR BRAIN AND FASTING

One of the biggest misconceptions is that our brain can only use glucose for energy, but this could not be further away from the truth. In reality, while in the fasting state, our brains can utilize ketone bodies as a source of energy.

While fasting, brain proteins increase as the stress of fasting causes the body to preserve this very important organ. One of the most important brain proteins is a brain-derived neurotrophic factor, BDNF. This protein works by growing neurons and as a natural antidepressant. In addition, it has been shown to help neurons stay healthier and resist brain diseases like dementia.

A study conducted by Dr. Bredesen consisted of ten patients with early signs of Alzheimer’s disease. The patients started to fast for 12 hours a day and were tested for cognitive improvement or decline. Within 3-6 months, nine out of the ten patients had shown a reversal in cognitive decline. Studies on the cognitive benefits of fasting are booming and more research is being invested to show the benefits of fasting on the brain.

OVERALL BENEFITS OF FASTING

As we’ve seen, fasting is great for brain health, but the benefits do not end there. Fasting has been proven to increase levels of human-growth hormone, HGH, which is essential for cellular regeneration and decrease in body fat. It has also been shown to reduce insulin resistance and in this way decreases the chances of type-2 diabetes.

With all of the benefits of fasting, it is no wonder why this new lifestyle is gaining popularity so fast.

Does Not Wearing Glasses Mean Contact Lenses for Life?

“Why don’t you try contact lenses,” my optometrist offered when I told him I hated my glasses. This is a more common situation than not. I hated spending $200 on glasses each time I wanted to change my style, which is already on the lower end of the price range. Similarly, getting contacts would mean spending up to $1200 a year! Thus, are contact lenses the only solution to glasses?

NO!

I am sure you have heard of the term myopia and presbyopia or even astigmatism. These are all different types of refractive errors; a condition where the shape of your eye does not bend light properly. With the introduction of refractive surgery, the eye care scene grew drastically with new methods to correct refractive errors through changing the eye’s structures.

Where to Start?

Like any medical procedure, you will arrive for your initial consultation. Your visit will likely begin with the careful investigation of your medical history and countless tests to assess your eye. Then your doctor will discuss the different procedures you are a candidate for. Two of these are LASIK and PRK.

What is LASIK?

Laser-assisted in situ keratomileusis or more commonly known as LASIK, is the most well-known refractive surgery technique.  By using a laser, ophthalmologists form a thin flap in the cornea – a transparent dome covering the outermost layer of the eye – making the removal of a specific amount of corneal tissue possible, before refolding the flap into its original position. This alters the eye’s ability to focus light.

What is PRK?

Do you enjoy sports or just have a very active lifestyle in general? If so, another type of refractive surgery called photorefractive keratectomy (PRK) is perfect for you. In contrast to LASIK, where instead of creating a corneal flap that can become dislodged with intense movement, the doctor will remove the corneal epithelial, which will allow a laser to reshape the deeper cornea.

Am I Free From Corrective Lenses Now?

It would be pointless if your surgery does not improve your eyesight at all. That’s money down the drain! With any of the procedures, most people end up with 20/40 vision or better. Thus, you can leave your fashionable glasses at home!

Laser Correction Sounds Exciting, but Scary!

Unfortunately, there are inherent risks and potential side effects. Over time your eyesight will deteriorate and you might one day need glasses again to see properly. As for the immediate side effects of surgery, there is the rare chance of going blind, but in the hands of an expert surgeon the probability is 1 in 5 million. Instead, the possibility of chronic dry eyes is more worrisome. Thus, as you begin your journey remember to save up some money in advance for artificial tears!
