The FMD is low in protein, low in bad fats and high in healthy fat, in keeping with the researchers. It stimulates markers related to fasting, which includes low glucose levels and excessive degrees of ketone in our bodies, in order to mimic the results of prolonged fasting.
Dr. Longo and colleagues say their weight loss program should promote immune cell regeneration and longevity-related to fasting without the need for food restriction and the potential unfavourable results that include it.
"although the clinical results will require confirmation by way of a bigger randomized trial," they upload, "the outcomes of FMD cycles on biomarkers/danger elements for growing older, cancer, diabetes, and CVD, coupled with the very high compliance to the food plan and its safety, indicate that this periodic nutritional strategy has high potential to be powerful in selling human healthspan."
The team hopes that clinicians will at some point have the potential to prescribe this weight loss plan to patients. "This is arguably the primary non-continual preclinically and clinically examined anti-growing old and healthspan-promoting intervention shown to work and to be very possible as a health practitioner or dietitian-supervised intervention," says Dr. Longo.
