Can This Eating Plan Stop the “Root of Disease?”

Getting older can feel like your body is slowly shutting down…

You’re exhausted all the time… your energy levels are tanking… and nagging health problems start to pop up.

Well, you’re not imaging it… if you’re like lots of seniors, your body’s energy-producing system is going on the fritz.

Your mitochondria – the power centers of your cells – don’t work as well as they used to.

And that does more than leave you constantly fatigued. Mitochondrial dysfunction is actually the root of several serious – and even deadly – diseases.

But new research is showing that a simple eating plan could hold the secret to restoring mitochondrial health at any age.

And I believe in this eating strategy so much, I follow it myself.

We all remember from high school biology class how the mitochondria in our cells produce ATP – the energy currency for our bodies.

But here’s something they don’t teach you…

Mitochondrial dysfunction has now been linked to several serious diseases, like Alzheimer’s, diabetes, and even cancer.

Unhealthy mitochondria put you on the fast path to premature aging and early death – simple as that.

So in a new study in Aging Cell, researchers wanted to see if putting mice on an intermittent fasting diet could help improve their mitochondrial health.

And, boy, did it…

Intermittent fasting is a simple eating plan where you limit your food intake to a specific time window each day. For example, you may eat all of your meals between 10 am and 6 pm, and fast the rest of the time.

When the mice were put on a fasting diet, their mitochondrial health improved dramatically.

First, researchers noticed that the mitochondria started functioning better and more efficiently.

Second, they saw mitochondria begin to “fuse.” That’s a process by which cellular mitochondria literally connect to share energy and repair materials, and resist stress and damage.

Why would something as simple as intermittent fasting force mitochondria to work better? Well, fasting forces the mitochondria to adapt and function more effectively.

So what could this improved mitochondrial health from intermittent fasting mean for you?

Well, as I said, healthy mitochondria can help several types of diseases from ever taking hold in your body.

So it’s no surprise that previous research has linked intermittent fasting to lower risk of diabetes, heart disease, cancer, Alzheimer’s and more.

Protecting your mitochondria is one of the most important things you can do to improve your health as you age. And intermittent fasting is a great way to get started.

Personally, I follow the 8:16 method. I eat within an 8-hour window each day, and I don’t eat for the other 16.

This takes discipline and consistency – but give it a try, and I think you’ll notice big changes in your health.
