People looking to lose fat quickly have turned to all types of fad diets over the past few decades. From low fat to high fat to low carb to gluten free to 6 small meals a day to raw veggies without dressing.
Well, if you’ve tried any of these fad diets then you’ve probably come to a realization that either it was too difficult to be consistent with or the results weren’t worth the strict diet.
What's a simpler solution?
The solution could simply be skipping a meal or two a few days a week.
Ever heard of intermittent fasting?
This is fasting for a short amount of time ranging from 14 to 36 hours. Think that’s too difficult? Think about the fact that each of us “fasts” every day; it is just known to us as “sleep”. All you need to do is extend that period of time a few more hours.
Why would you do this?
To lose weight, feel better, and to improve body composition.
What is the science behind intermittent fasting?
As far back as the 1930’s researchers found that by drastically reducing the number of calories consumed by mice lead to a longer healthier life. Since then the same studies with similar results have been performed on other animals such as monkeys, fruit flies and roundworms.
According to Mark Mattson, senior investigator for the National Institute on Aging, part of the US National Institutes of Health says that fasting has been shown to improve biomarkers of disease, reduce oxidative stress and preserve learning and memory functioning.
The six most common types of intermittent fasting all have the common goal of achieving the benefits of fasting with varying approaches. You should choose the method that fits your daily schedule and lifestyle. If you choose a method that isn’t in tune with your lifestyle, chances are you won’t last too long. So, pick one that you think best suits you then reap the benefits of fasting.
As in all diets, intermittent fasting isn’t right for everyone. Before making a drastic change in your daily nutrition routine please consult your doctor, especially those with existing health conditions. Please keep in mind that the intermittent fasting method should be in sync with your individual goals and daily lifestyle.
Please note that these methods used in conjunction with regular exercise will yield far superior results.
