Now scientists believe that the ‘yo-yo effect’, gaining weight after successfully dieting, may be caused by bacteria in our guts. While our body loses weight, the microbes living inside us used to a fatty diet remain for many months. And when they come across fatty foods again, they go into overdrive, making us pile on the pounds at an accelerated rate. This effect could be reversed, scientists believe, by taking a drink containing high levels of the substances which are found naturally in fruit and vegetables.

Key Takeaways:

• While our body loses weight, the microbes living inside us used to a fatty diet remain for many months.
• And when they come across fatty foods again, they go into overdrive, making us pile on the pounds at an accelerated rate.
• While this effect may once have been helpful – perhaps making us store extra fat after a time of famine – nowadays it is harmful.

“Researchers believe the ‘bad’ gut bacteria cause a fluctuating weight by destroy natural compounds found in our food that encourage us to burn fat.”
