The benefits of intermittent fasting

Here is a summary of the benefits of intermittent fasting.
Intermittent fasting has cured some people with type 2 diabetes, and some in as little as two weeks, as noted by Jason Fung, MD who is the author of the book The Complete Guide to Fasting: Heal Your Body Through Intermittent, Alternate-Day, and Extended Fasting.
Intermittent fasting has allowed some people with type 2 diabetes to get off of insulin (which is a great thing).
Intermittent fasting has allowed some people to get off of all prescription drugs including those for diabetes, blood pressure, cholesterol, and some in a very short time (in as little as 1.5 months according to one patient Dr. Fung talked about).
May prevent blindness, amputations, cardiovascular disease and kidney disease caused by Type 2 diabetes
Although it is impossible to prove that something did not happen because of an intervention…
It seems likely that by curing someone’s diabetes, intermittent fasting would also prevent the complications of type 2 diabetes such as kidney damage, blindness, amputations, cardiovascular disease, etc.
Reduced body fat, body weight, improved insulin and blood sugar levels
Mice that limited eating to only 8 hours per day and fasted 16 hours per day and ate the SAME number of calories as control mice (who were not limited to when they could eat) had:
- reduced body fat (those that limited eating to only 8 hours per day and fasted 16 hours per day had only one-fourth as much body fat even though they ate the same number of calories: 4 grams of body fat vs 18 grams of body fat)
- reduced body weight (those that limited eating to only 8 hours per day and fasted 16 hours per day weighed 28% less even though they ate the same number of calories: 34 grams versus 47 grams)
- prevented obesity on a high-fat diet
- increased release of fat from fat cells (so that more body fat is burned)
- improved glucose tolerance (those that limited eating to only 8 hours per day and fasted 16 hours per day had normal glucose tolerance whereas control mice did not)
- improved insulin levels (those that limited eating to only 8 hours per day and fasted 16 hours per day had normal insulin levels whereas control mice did not)
Reduced fatty liver, reduced inflammation, increased motor coordination
The mice who limited eating to only 8 hours per day and fasted 16 hours per day also had:
- reduced fatty liver
- reduced inflammation
- reduced leptin resistance
- increased motor coordination
Fasting 2X per month increased lifespan by 11%, reduced cancer, increase bone density
Middle-aged mice that were fasted twice (2X) a month showed the following benefits:
- lived 11% longer than control mice
- reduced inflammation
- reduced dermatitis
- reduced tumors by about 50%
- tumors were less likely to be cancerous and more likely to be benign
- improved learning
- improved memory
- reduced visceral fat (belly fat)
- caused no loss of muscle mass
- increased bone density (compared to mice that did not fast)
Fasting does NOT reduce metabolism, does not cause muscle loss
Jason Fung, MD notes that:
- fasting does not reduce metabolism (one study found metabolism was 10% HIGHER after 4 days of fasting)
- fasting does not cause low blood sugar
- fasting does not provoke overeating
- fasting does not cause muscle loss
Fasting has a regenerative effect on cells
Intermittent fasting has a regenerative effect on cells, allowing old cells to die off, and then new cells replace them.
Fasting may activate immune system against cancer
Fasting may activate the immune system and expose cancer cells to the immune system.
Fasting starves cancer
Short-term fasting starve cancer cells.
Short-term fasting allows chemotherapy to better target cancer.
Short-term fasting made cancer-killing cells more effective at attacking and shrinking tumors.
3-day fast has lower side effects than 1-day fast
72-hour fasts are associated with lower side effects compared to 24-hour fasts.
Conclusion: Intermittent fasting has tremendous benefits
It looks to me like intermittent fasting has tremendous benefits.
