Intermittent fasting can have serious side effects!
Intermittent or intermittent fasting is, in short, the voluntary restriction of the time during which one can eat.
The most popular protocol is the 16-hour window in the day, but there are many others, such as 18:6, 5:2, Eat/Stop/Eat and the Warrior Diet.
I make a short introduction to it by describing its greatest benefit in "How many meals a day should we eat" .
A recent study, however, found that intermittent fasting is not only not as beneficial as the internet gurus would have you believe, but it can have side effects on your health!
The survey consisted of 88 women, who were divided into 4 groups:
- IF70: Intermittent fasting group, in the calculated 70% of daily caloric needs
- IF100: Intermittent fasting group, at the calculated 100% of daily caloric needs
- DR70: Group of otherwise normal diet, at calculated 70% of daily caloric needs
- Control Group: The group that participated in the experiment without taking part in the experimental procedure
There were several notable findings from the experiment, but the important thing was that in the 2 groups of intermittent fasting, because the participants had to eat more in the time frame given, there was a transient deterioration in insulin sensitivity.
This shows that intermittent fasting when not conditional on caloric loss can have bad effects on metabolic health!
