Fasting and cellular regeneration -
Ketone bodies are the byproducts of fat metabolism. The researchers found that mice that had fasted between 1 and 2. This reduced regenerative capacity persisted for up to three days after the mice began feeding again and returned to a normal body weight; it returned to normal within one week of the end of the fast.
Further research showed that muscle stem cells from fasting animals were smaller and divided more slowly than those from non-fasting animals. But they were also more resilient: They survived better when grown on a lab dish under challenging conditions including nutrient deprivation, exposure to cell-damaging chemicals and radiation.
They also survived transplantation back into animals better than those from non-fasting animals. Muscle stem cells isolated from non-fasting animals and then treated with a ketone body called beta-hydroxybutyrate BHB displayed a similar resilience as did those from fasting animals, the researchers found.
Additionally, muscle stem cells isolated from mice fed a ketogenic diet, or a normal diet coupled with injections of ketone bodies, displayed the same characteristics of the deeply quiescent stem cells from fasting animals. Finally, the researchers isolated muscle stem cells from old mice that had been treated with ketone bodies for one week.
But treatment with the ketone bodies allowed the old muscle stem cells to survive as well as their younger counterparts. Ketone bodies arise when the body uses fat for energy, but they also push stem cells into a quiescent state that protects them during deprivation.
In this state, they are protected from environmental stress, but they are also less able to regenerate damaged tissue. Balancing these outcomes might one day help combat normal aging and enhance stem cell function throughout the body, the researchers speculated.
The research was supported by the National Institutes of Health grants T32GMA1, PO1AG, R37AG and RO1AR , the Buck Institute for Research on Aging and the Department of Veterans Affairs. Researchers from UC Berkeley; the Veterans Affairs Palo Alto Health Care System and the Mondor Institute for Biomedical Research in France are co-authors of the study.

Further studies, including sequencing the mRNA of stem cells from the mice that fasted, revealed that fasting induces cells to switch from their usual metabolism, which burns carbohydrates such as sugars, to metabolizing fatty acids. This switch occurs through the activation of transcription factors called peroxisome proliferator-activated receptors PPARs , which turn on many genes that are involved in metabolizing fatty acids.
The researchers found that if they turned off the FAO pathway, fasting could no longer boost regeneration. They now plan to study how this metabolic switch provokes stem cells to enhance their regenerative abilities.
Pharmacological targeting of this pathway may provide a therapeutic opportunity to improve tissue homeostasis in age-associated pathologies. The researchers plan to explore the potential effectiveness of such treatments, and they also hope to study whether fasting affects regenerative abilities in stem cells in other types of tissue.

In rwgeneration mice anx a Cellupar 1 human clinical trial, Fasting and cellular regeneration periods of not Fatsing significantly lowered white blood cell counts. In mice, fasting cycles then flipped a regenerative switch, changing the signaling pathways for hematopoietic stem cells, which are responsible for the generation of blood and immune systems, the research showed.
Longo, who has a joint appointment at the USC Dornsife College of Letters, Arts and Sciences, said the study has major implications for healthier aging, in which immune system decline contributes to increased susceptibility to disease as people age. By outlining how prolonged fasting cycles — periods of no food for two to four days at a time over the course of six months — kill older and damaged immune cells and generate new ones, the research also has implications for chemotherapy tolerance and for those with a wide range of immune system deficiencies, including autoimmunity disorders.

| Does Intermittent Fasting Promote Cell Repair? | Chad Richardson is a freelance writer from Cincinnati, OH who also enjoys going to the gym and doing his best Arnold Schwarzenegger impersonation, scrolling through Netflix trying to find a new binge-worthy show, and catching a game to root on his hometown sports teams. One group that could benefit from such treatment is cancer patients who are receiving chemotherapy, which often harms intestinal cells. But what exactly happens to your cells when you intermittent fast? Medically reviewed by Alana Biggers, M. Further research showed that muscle stem cells from fasting animals were smaller and divided more slowly than those from non-fasting animals. The research explores how the body responds in times of deprivation and plenty and gives clues about the effect of aging on the ability to regenerate and repair damaged tissue.
