Our brains do n’t like being overfed , as obesity can mature the brain untimely and even make it more vulnerable to Alzheimer ’s and Parkinson ’s . Now we ’ve reveal the diametric effect : a rigid diet turns on atom that keep the mentality young .

Scientists searching for the key to extending human lives have put a lot of tending on thermic confinement , which means placing someone on a cheeseparing - starvation diet that only allow 70 % of normal solid food consumption . In animals , caloric confinement has repeatedly been shown to greatly extend normal lifetime . We do n’t know for sure whether this would work in humans , but that ’s partly because it could take a hundred years to screen it out on humankind .

But the advantages of thermal confinement do n’t just deal with longevity , according to researchers at the Catholic University of Rome . Mice rank on these extreme diets show greater cognitive power than their counterparts and they are less belligerent . Most excitingly , they only rarely originate Alzheimer ’s disease , and when they do the symptom lean to be much less serious than in those of other mice . Effectively , thermic restriction is keeping mouse Einstein young .

That ’s all well and good , but it is n’t of much use to us humans if we do n’t have a go at it why such diets make the brain younger – after all , we ca n’t just starve a bunch of the great unwashed for the next thirty class and trust their idea better . Ethically address , that ’s a no - no . That ’s where the Italian investigator have made such a all important find . They ’ve identified the specific molecule that is activate by caloric restriction , and how it changes the brain .

That molecule is call CREB1 , and it ’s triggered by these uttermost dieting . In turn , the molecule activates factor linked both to longevity and to the proper , more efficient functioning of the mastermind . We already know that CREB1 helps regulate brain purpose like memory , scholarship , and ascendance of anxiety , and that senescence reduce the effect of this molecule . Now we know that reduced caloric intake can improve the molecule ’s carrying into action , and even slacken the oncoming of ageing in the brain .

In fact , it seems that the benefits of caloric restriction in the encephalon are all to do with CREB1 – when the corpuscle is removed from the black eye ’s mental capacity , caloric restriction has no cognitive welfare . The researchers think this same mechanism should exist in mankind . squad loss leader Dr. Giovambattista Pani says he hopes to discover new drugs that can super - charge the energizing of CREB1 without having to go such an extreme dieting . If they are successful , we could keep our head new and fitter than ever , while still being countenance to enjoy a full repast .
