- Fasting triggers a protein that causes immune cells to make fat cells burn lipids
- The approach can prevent obesity with dieters eating normally on non-fast days
- Past research reveals fasting reduces abdominal fat, which is linked to cancer
- Plus weight loss, fasting improves blood pressure, gut health and brain function
- Researchers from The Hospital for Sick Children in Ontario conducted the study
Intermittent fasting can cause substantial weight loss in just weeks, new research reveals.
Mice who are fed a normal diet for two days followed by 24 hours without food shed pounds after just six weeks, a study found.
Researchers believe fasting triggers a protein that causes white blood cells to stimulate fat cells to burn lipids.
Study author Professor Kyoung-Han Kim from The Hospital for Sick Children in Ontario, said: ‘Intermittent fasting without a reduction in calorie intake can be a preventative and therapeutic approach against obesity and metabolic disorders.’
Previous research reveals fasting reduces abdominal fat, which is linked to an increased risk of type 2 diabetes, heart disease and certain cancers.
As well as weight loss, extreme calorie restriction has also been associated with improved blood pressure, gut health and brain function.

How the research was carried out
The researchers exposed mice to 16 weeks of intermittent fasting.
The animals were fed a normal diet for two days, followed by 24 hours with no food.
Intermittent fasting causes weight loss in weeks
Results revealed intermittent fasting causes substantial weight loss after four months.
A further experiment demonstrated the same findings occur after just six weeks of going without food every third day.

The researchers believe fasting triggers a protein that causes white blood cells to stimulate fat cells to burn lipids.
They add the effects reverse once mice start eating again.
The findings were published in the journal Cell Research.
