About 6 weeks ago I discovered something called intermittent fasting. Intermittent fasting can take various forms, but the most common are a 16 x 8, or a sporadic 24 hour fast. The 16 x 8 method is when you fast for 16 hours and have an 8 hour eating window. For people that work during the daytime, it makes sense to have your last meal at 7:00 or 8:00 p.m. and then not eat again until noon or lunch time. This provides you with a 16 or 17 hour fast, essentially skipping breakfast. I have been using the 16 hour fast method on a daily basis for about 6 weeks now, and found it to be fairly easy to accomplish. The first week is probably the hardest, but fortunately it becomes easier with time. Most of the fast is spent sleeping so depending on when you get up you may only go without food for 5 or 6 hours. I personally lost 5 pounds in the first 4 weeks, and this weight loss was in body fat. Here are some reasons you might want to adopt an intermittent fasting routine:
- Changes The Function of Cells, Genes and Hormones
- Insulin levels: Blood levels of insulin drop significantly, which facilitates fat burning
- Human growth hormone: The blood levels of growth hormone may increase as much as 5-fold. Higher levels of this hormone facilitate fat burning and muscle gain, and have numerous other benefits.
- Cellular repair: The body induces important cellular repair processes, such as removing waste material from cells.
- Can Help You Lose Weight and Belly Fat
- Lower insulin levels, an increase in metabolism, and higher growth hormone levels, are combined to use fat as an energy source. This occurs because you have no carbohydrates in your system to burn, so your body turns to the next available source of energy body fat.
- Can Reduce Insulin Resistance, Lowering Your Risk of Type 2 Diabetes
- Intermittent fasting has been shown to improve insulin resistance and lead to an impressive reduction in blood sugar levels
- In human studies on intermittent fasting, fasting blood sugar has been reduced by 3-6%, while fasting insulin has been reduced by 20-31%
- Induces Various Cellular Repair Processes
- Fasting causes the cells in the body initiate a cellular “waste removal” process called autophagy
- This involves the cells breaking down and metabolizing broken and dysfunctional proteins that build up inside cells over time.
- Increased autophagy may provide protection against several diseases, including cancer and Alzheimer’s disease.
Other benefits may include:
- Helping to prevent cancer
- Intermittent fasting is good for your brain
- May protect against Alzheimer’s Disease
- May extend your lifespan
With so with so many benefits that have been attributed to intermittent fasting, it is worth researching. In fact I have not been able to find any research that indicates any negative effects. The only caution here is if you are someone with an unusually low percent of body fat or an anorexic.
My advice is that unless you are doing this strictly as some form of dieting, make sure you are getting those calories in during your eating window. I personally like the 16 x 8 method versus a 24 hour fast. I’ve tried the 24 hour fast and while it is a great way to cleanse your body, it is much more difficult and in most cases you will be very hungry during those additional 8 hours of fasting that you have added on.
To make the fasting period a bit easier you will need to consume some liquids like coffee, tea, or water. This helps by providing something in your stomach, making it easier to endure the fast. Do not consume liquids that contain calories, so no sugar in your coffee or tea and avoid any other liquid that contains sugar like soft drinks.
The YouTube video below provides a great overview of the benefits and different types of intermittent fasting methods. I highly recommend you spend the 10 minutes to view this as part of your own research.
I personally don’t view intermittent fasting as a diet, but more of a way of enhancing your health. It is entirely possible that you will not lose any weight at all if you continue to have an unhealthy diet, but if you combine intermittent fasting with a healthy diet there is a good chance that you will lose fat and improve your body composition. Do your own research, and let me know what you think.
