This discovery was made by Brazilian scientists – intermittent fasting increases the risk for type-II diabetes.
This is after all the articles on the benefits of intermittent fasting? Yes, in their opinion fasting throughout the day weakens the action of insulin.
Scientists at the University of Sao Paulo subjected healthy rats to 3 months of intermittent fasting, eating every other day.
Here, the reader may be relieved, and feel the same that a well-known psychologist did about such studies years ago – “They have the daring hypothesis that man is descended from rats”.
But the rats, unlike the scientists, quickly lost weight, and the cells that produce insulin were damaged.
The Brazilian scholars themselves write about this discovery:
“This is the first study to show, that despite losing weight, intermittent fasting can actually damage the pancreas and affect insulin function. This can lead to diabetes or serious health problems”.
If this data is then boldly applied to people, then the conclusion could be made that people with obesity who begin fasting may already have insulin resistance. They will quickly lose weight, and instead of excess weight will get diabetes.
Other experts reacted to the Brazilian study without enthusiasm. Work from our fellow countrymen at UCLA in 2017 shows that fasting restores the production of insulin and stabilizes glucose levels. In whom, you may ask? Mice.
So it seems that we may have conquered diabetes not only in rats, but also mice.
To be fair, though, it should be noted that these latest results were reproduced in humans.
British scientist Nicola Guess of the Royal College of London had the profound thought that there are difference between rodents and humans, especially in terms of diet.
And he is right:
“One day of fasting in rats is the same as 3-4 weeks in humans!”
So, it’s too early to make conclusions about new discovery, but it’s still something to keep in mind.
