The Science (and Benefits) of Intermittent Fasting
Today, we’re going to take a closer look at the science behind intermittent fasting and the benefits it can provide.
As fasting has grown in popularity over the years, so has the amount of research being done to study how this way of eating affects the human body.
At this moment in time, much of the existing research for disease prevention has been conducted mostly, if not entirely, in animal trials; as a result, the conclusions must be taken with a pinch of salt, as they would not necessarily have the same effect in humans.
That being said, the results of these studies are as fascinating as they are promising, not to mention the fact that the other benefits (aside from disease prevention) have been proven in humans.
Let’s jump in.
Intermittent fasting improves insulin sensitivity. Improving insulin sensitivity and lowering your insulin levels when fasted helps your body access stored fat for energy more easily. This can lead to an increase in fat burn while you’re in a fasted state. 
Intermittent fasting can help protect you against Alzheimer’s. A study conducted in rats showed that IF and calorie restriction used together may both delay the onset of, and reduce the severity of, Alzheimer’s disease. 
In addition, a lifestyle intervention program conducted with humans that included short-term fasting proved to be successful at reducing the severity of Alzheimer’s symptoms in nine out of ten of the participants. 
Intermittent fasting increases your levels of growth hormone. Growth hormone is naturally produced in the body and works to, among other things, help with fat loss, building muscle, and muscle retention. 
Intermittent fasting can help prevent cancer. No human trials have currently been conducted, but animal trials have shown that IF may help prevent cancer. 
Intermittent fasting speeds up your metabolism. Fasting has been shown to increase metabolism by anything from 3.6% to up to 10%, which may not sound like a lot but can add up over time to result in more fat burned and more weight lost. 
Intermittent fasting can help protect against type 2 diabetes. As a result of IF reducing insulin resistance and blood sugar levels, research suggests that it can help protect against the development of type 2 diabetes. 
Intermittent fasting reduces your daily calorie intake. A study conducted at the University of Illinois found that those who used a daily fasting setup ate, on average, 300 calories less than those using a traditional diet setup. 
This means 2,100 less calories a week and 8,400 less calories a month. This is huge and could spell the difference between no progress and great progress for many people.
As you can see, there are numerous benefits to be gained from using IF.
In tomorrow’s lesson, we go beyond the science and look at how IF can drastically improve your diet adherence, provide huge amounts of nutritional freedom, and generally make your life easier.
