Tips on how to begin intermittent fasting and its 7 benefits for health

What is Intermittent Fasting?

Intermittent fasting is something of a fad, but did you know it is rooted in ancient practices?

Fasting has been happening for years, often in connection with religious observance. All the major religions have fasting as a part of their practice in some form.

Although fasting specifically for health is not such an ancient practice, it still brings me much reassurance to know it has been done for thousands of years with much success.

Intermittent fasting is different from extended fasting. Intermittent fasting is best understood as fasts of as little as 12 hours and as long as 72 hours. The most common is 16-20 hours, often done daily or 3-6 days/week. You then have between 8 and 4 hours left for 1-2 meals.

Benefits of

Intermittent Fasting

Intermittent fasting has a number of benefits. As more research is done, more benefits are being recognized. I have practiced intermittent fasting since the middle of 2016 and plan to continue the rest of my life.

#1 Fasting is Free and Simple

One of the best things about fasting is that it is free. If you practice it regularly you will save money.

Although it is not always easy, it is very simple. You simply don’t eat for a set period of time. There are no complicated diets to figure out, which is part of the appeal.

#2 Fasting Can Lead to Weight Loss

One of the biggest draws of intermittent fasting is to those who want to lose weight. Weight loss happens when fasting for several reasons.

The most obvious, but not necessarily the most significant, is people often eat less food because they are not eating 3 (or more) meals a day.

What I believe is more significant is that insulin levels are lowered when fasting. Insulin resistance is a very common cause of weight gain and the inability to lose weight. Insulin resistance is tied up with type 2 diabetes, which is a very common problem in the world today, especially in industrialized countries.

Intermittent fasting also keeps metabolism from slowing down and stopping weight loss, which is the most common reason that most diets fail.

#3 Intermittent Fasting Can Prevent or Reverse Type 2 Diabetes

Personally, this is a very significant reason for me to fast. I was able to lower my own blood sugar because the fasting broke the insulin resistance that has been with me for some years now.

With insulin resistance, the cells are no longer sensitive to insulin (which normally works to move glucose into the cells) and so the body produces more and more insulin, which prevents the body from burning fat for energy.

Insulin resistance also leads to type 2 diabetes which is linked with heart disease, high blood pressure, kidney disease, and other problems. Fasting lowers insulin levels, the factor behind much of the damage in type 2 diabetes.


#4 Fasting May Improve Heart Health

This also connects to the insulin resistance mechanism mentioned earlier. With a decrease in insulin resistance, cholesterol levels and triglycerides improve, and thus heart health improves as well.

Another connection is often a lowering of blood pressure, especially when the cause of elevated blood pressure is a build-up of plaque in the arteries and a hardening of those arteries.

Maria Emmerich mentions the connection between insulin resistance, blood pressure, and magnesium in her book Keto-Adapted. Magnesium is a mineral that relaxes muscles in the cells. If the cells are insulin resistant, then more magnesium will be lost out of the body and the blood vessels will constrict, rather than relax, and blood pressure will
become elevated.

Fasting will contribute to the retention of more of that magnesium through breaking insulin resistance, and thus blood pressure may decrease.

#5 Fasting Improves Memory

Another significant benefit of fasting is that it can benefit your brain and help your body stay young longer. Memory improves with calorie reduction and lower insulin levels.

Our bodies are constantly replacing cells that have reached a certain age. Increased levels of sugar, insulin, and protein can also interfere with the process of this cell replacement.

Fasting can help the body to clear out the old and damaged cells, and then restore them with new replacement cells, a process known as autophagy.


#6 Intermittent Fasting May Reduce Cancer Risks

As mentioned above, fasting clears out old and damaged cells, which includes cells that are prone to cancer. It can turn on certain genes that repair specific tissues and clean out the damaged ones, all cells which are more susceptible to cancer.

Animal studies have shown that intermittent fasting can reduce the incidences of spontaneous cancers.

#7 Fasting Improves Gut Health

Intermittent fasting gives your gut microbes a break from their hard work, so they can focus on cleaning up their populations and increase their diversity. This will boost your overall health and aid in your body’s resistance to the detrimental bacteria.


How to Start Intermittent Fasting

Fasting is not complicated; it’s simply not eating for a period of time. However, a few tips can make it easier to get started:

  • Start out with 14 to 16 hours of fasting. Leaving 10 to 8 hours to eat 2 to 3 meals. You can gradually increase your hours of fasting and even throw in a 24 hour fast once in a while.
  • Fast as clean as possible. That means no food and only drinking water, black coffee, black tea, green tea, herbal teas (avoid fruity teas), mineral water, plain seltzer, and carbonated water. Avoid all sweeteners when fasting, even the alternative ones. (Make sure your water is clean!)
  • Increase healthy fats in your diet, especially before starting a fast as that helps keep you satiated longer and prevent hunger pangs.
  • Be flexible and make fasting work for you and your lifestyle.
