“Nonetheless, these are solely simulations — and extra research are obligatory to verify this potential of the FMD cycles,” he added.

Prior research in mice have recognized extra advantages of the FMD, together with diminished threat of age-related illnesses like most cancers, heart disease and diabetes, Vongo identified.
