Supplementing the diet of healthy middle-aged mice with a mixture of amino-acids - the building blocks of proteins - extended their average lifespan by over one tenth.
By removing a protein that muscles use to convert fuel into energy, the researchers produced a mouse with normal body weight but which did not have enough energy to exercise.
Regular endurance exercise reduces the effects of ageing, according to new research on mice.
