It also helps keep the body's inflammatory response in check. Consult with your doctor first before starting intermittent fasting to kickstart autophagy. When fasting starves the cells, autophagy helps digest some of the cell components, to provide the necessary energy for survival. Recycles damaged cell parts into fully functioning cell parts. Many people are interested in using fasting and calorie restriction to induce autophagy, but there is little evidence on the precise effect this has on humans. Therefore, more human studies are needed to understand whether autophagy itself affects body composition. While there is plenty of research on autophagys effect on cells, researchers are still unsure about whether enhancing autophagy could be a new treatment for different conditions.

Indeed, there is evidence that exercise increases autophagy in human skeletal muscles. Fortunately, this side effect is temporary, as research suggests energy levels increase with time as your body adapts to the ketogenic diet. Fortunately many of the foods you consume on a daily basis contain spermidine, though spermidine content among these foods varies widely, making it difficult to gauge how much spermidine you are consuming through diet alone. Autophagy is considered one of the key molecular mechanisms for the broad preventive and therapeutic effects of periodic fasting. Experts recommend fasting for 16 to 18 hours a day to reap the benefits. Several of the methods used to induce autophagy, including fasting or following a ketogenic diet, have been linked to low energy levels and fatigue (15, 16, 17). Autophagy (pronounced ah-TAH-fah-gee) is an opportunity for your cells to take out the garbage, says Cynthia Thurlow, NP, nurse practitioner and functional Still, researchers have identified some promising potential benefits of autophagy: By removing accumulated, damaged cellular material, autophagy may lead to a decline in age-related diseases and increased longevity. Autophagy occurs when your bodys cells are deprived of nutrients or oxygen or if theyre damaged in some way. In other words, the autophagy process basically works by using waste produced inside cells to create new building materials that aid in repair and regeneration. Autophagy is indeed essential for healthy cells. Cells then recycle that material for fuel and building blocks for new cellular parts, according to a January 2012 paper in Experimental & Molecular Medicine.
