In this study, we have demonstrated that fisetin prevents diet-induced obesity through regulation of the signaling of mammalian target of rapamycin complex 1 (mTORC1), a central mediator of cellular growth, cellular proliferation and lipid biosynthesis.

Is fisetin an effective senolytic?

Recent research has found fisetin to be one of the most effective senolytic compounds yet discovered among plant polyphenols. By helping to remove dysfunctional senescent cells, fisetin may increase longevity and lower risk for disease.

Does intermittent fasting remove senescent cells?

“Intermittent fasting helps with longevity and getting rid of Senescent cells or 'zombie cells' by cellular autophagy (a process in which your body removes damaged cells and proteins),” says Cynthia Thurlow, an intermittent fasting and nutrition expert who has delivered a TED talk on the subject.
