Effect of a Periodic Fasting-mimicking Diet on Risk Factors for Metabolic Syndrome and Age-related Diseases
Description
Brief Summary
Evidence from bio-gerontology research from our laboratory and others have showed that
short-term fasting/starvation (STS) can improve the efficacy of chemotherapy by protecting
normal cells and tissues and potentially sensitizing malignant cells to chemo drugs.
Furthermore, STS improves risk factors associated with aging and age-related disease in
rodent models. Prolonged fasting, however, is difficult to implement and may not be feasible
or safe in humans. We have developed a fasting-mimicking diet (FMD) that was well accepted in
a pilot human trial. The objective of the study is to ascertain the impact of the
fasting-mimicking diet given to adult subjects for 5 days a month for 3 consecutive months.
The investigators hypothesize that the specially designed dietary regimen can reduce the risk
factors for metabolic syndrome and biomarkers associated with aging and age-related diseases.
Detailed Description
The Phase I part of the study is designed as a randomized cross-over trial, including two
arms: a Control arm and a multi-cycle special 5-day dietary regimen (Diet, 3 cycles) arm.
After 3 cycles, the Control and Diet groups are crossed over such that the Control group will
under-go dieting and the Diet group will return to normal diet. Participants will be
monitored for body weight and physiological changes, as well as the adherence to the dietary
intervention.
The Phase II part of the study is an expansion of the Phase I to ascertain the impact of the
dietary intervention on risk factors for metabolic syndrome and biomarkers associated with
aging and age-related diseases.
Statistical methods: Paired samples t-test and Mann-Whitney test will be used to compare
between Control and Diet groups as well as pre- and post-diet values.
