The temptation to gobble up whatever you can find when on a relaxing break abroad can often prove too hard to resist.
But splurging on food when you go on holiday can give you ‘obese brain’, scientists have revealed.
A week of indulgence can change the chemical makeup of your brain to make it behave as if you are overweight.
The short term consumption of sugars and fats from treats you might not normally eat will affect your brain’s behaviour before your body puts on any weight.
It makes the brain behave like an obese person, the scientists found.
These cerebral changes are then slower to return to normal than any other bodily impact of the food itself.
The University of Tubingen in Germany plastered 18 young, healthy men with chocolate bars and salami for five days to increase their caloric intake.
Even though they put on no weight, their brains became more resistant to insulin for a week after their eccentric diet ended, compared to a group who had healthy meals.

Changes caused by diet were longer lasting in the brain than they were in the rest of the body.
Prof Stephanie Kullmann, who led the study, explained that ‘Our data indicate that the brain and behaviour response resemble that of a person with obesity and changes in the brain seem to occur prior to weight gain.’
‘the changes in the brain outlasted the timeframe of the consumption.
‘behaviourally, we see that participants show changes in reward behaviour: Reduced reward sensitivity, this could lead to greater food intake,’ she told the Telegraph.
