Ditch your diet and gym session and simply eat less to live a longer life,a leading scientist has claimed.
Dr Michael Mosley,a presenter on BBC science show ‘Horizon’ has claimed that ongoing research suggested that a high metabolic rate- how much energy the body uses for normal functions- is a risk factor for earlier mortality.
Communities in Japan and the US which follow strict,low-calorie diets appear to have a lifespan longer than the global average, he said.
Ultimately,ageing is a product of a high metabolic rate,which in turn increases the number of free radicals we consume, he said
If you stress the body out by restricting calories or fasting,this seems to cause it to adapt and slow the metabolism down. It’s a version of what doesn’t kill you makes you stronger, he said.
Mosley said he did not believe it was necessary to eat three meals a day because ‘what we think of as hunger is mainly habit’.
In a new Horizon programme,he also suggests that intermittent fasting could offer the same benefits as calorie restriction by reducing the growth of hormone IGF-1.
While the hormone maintains and repairs tissue,high levels have been shown to contribute towards cancer and ageing.
His comments come after the Institute of Health Ageing at University College London suggested eating 40 per cent less could extend a person’s life by 20 years,the report said.
