Ketosis increases ketone levels, resulting in autophagy (22). And undoubtedly, it seems that intermittent fasting is the surest way to achieve this effect. Due to autophagys role in regulating tumor suppressive genes and oncoproteins in many cancers, researchers are studying autophagy treatment as a potential therapy for cancer patients. Also, he discourages people from fasting for more than 14 days; such a long period of fasting can lead to refeeding syndrome a dangerous shift in fluids and minerals that might occur when food is re-introduced after a long fast.

Fasting 16:8 means you can only eat eight hours a day. The entire basis behind Dr. Jason Fungs intermittent fasting idea is that the body exists only in two states the fed (high insulin levels) and the fasted (low insulin levels) state. Polycystic diseases like kidneys and ovaries are too much growth. This sets in motion the process of rejuvenation as our body rebuilds new proteins to replace the old ones. Autophagy, a cellular cleaning process, gets activated in response to certain types of metabolic stress, including nutrient deprivation, growth factor depletion and From what I understand, autophagy is a process that occurs regularly within certain organisms (like people, mice, and yeast), but fasting and other forms of stress, like exercise, appear to accelerate it into a kind of cleansing overdrive.

Ultimately, current research supports Dr. Jason Fungs idea that intermittent fasting is an incredibly effective tool for weight and fat loss. mTOR is found in virtually all multi-cellular organisms and indeed, many single celled organisms like yeast (where much of the research on autophagy is done).
