Fasting Mimicking Diet

FMD during chemotherapy is presented as reducing side effects, improving survival outcomes, and maintaining healthy weight in most patients. The fasting mimicking diet is described as an adjunctive chemotherapy protocol involving a five-day caloric restriction cycle around treatment. There is not enough evidence to broadly recommend longer fasting protocols for people in their 70s and beyond. A fasting-mimicking diet is being studied in Alzheimer's patients, including some participants in their 80s, but early tolerability does not justify broad recommendations. The article says ketosis selectively stresses glucose-dependent cancer cells while normal cells adapt to fat-based fuel. The protocol reduces calories enough to induce ketosis. The article advises clinical supervision and oncology nutrition support for implementation. A five-day fasting-mimicking diet is currently considered appropriate up to roughly ages 65 to 70.
