Intermittent fasting is a technique primarily used for losing weight that comes with many health benefits. It involves changing your eating pattern without having to change your diet or exercise level.
There are many different ways to fast. Common practices include:
- Alternate day eating – one day on and one day off
- Time restricted eating – typically involves skipping breakfast (but I don’t approve)
- 5:2 fasting protocol – restrict calories to 500-700 per day for two days a week
Intermittent fasting is effective because it allows the body to enter its highest fat-burning state, which occurs about 8-12 hours after eating a meal. This helps eliminate body fat without sacrificing muscle mass. A typical eating schedule does not normally allow the body to reach this point.
1) Intermittent Fasting Helps You Lose Weight
Studies have found that the 5:2 fasting protocol has been the most effective for losing weight (R).
A 2013 study found that people who steadily reduced their daily calorie intake became more insulin sensitive and lost more weight compared to people who followed a regular eating pattern (R).
Intermittent fasting has been effective in preventing obesity (R).
Efficiency of metabolism is improved as a result of intermittent fasting (R).
2) Intermittent Fasting Can Prolong Your Life
Intermittent fasting can increase a person’s lifespan by up to 30% according to some researchers (if animal studies are an indicator) (R).
Intermittent fasting boosts the body’s stress resistance, which increases longevity in humans (R).
It helps protect and treat the body from disease, which can delay aging (R).
Intermittent fasting can prolong the health-span of the nervous system by impacting biological pathways that regulate the lifespan (R).
3) Intermittent Fasting May Reduce the Likelihood of You Getting Sick
In a study done on mice that were infected with salmonella, intermittent fasting lowered intestinal and systemic bacteria by boosting their intestinal immune system (R).
4) Intermittent Fasting Promotes Cardiovascular Health
- Decreases cardiovascular disease risk (R).
- Increases HDL cholesterol and lowers triglyceride levels and LDL cholesterol (R).
- Decreases resting heart rate and blood pressure (R).
- Improves circulation of triglycerides and cholesterol (R).
- Increases resistance to ischemic injuries (R).
- Reduces the risk of coronary heart disease (R).
5) Intermittent Fasting Decreases Cancer Risk
Intermittent fasting lowers blood glucose and IGF-1 levels, which reduces the risk of cancer (R).
Studies have found that reducing energy intake and fasting for longer intervals during the night can reduce the risk of breast cancer (R).
6) Intermittent Fasting Can Forestall Cognitive Decline
Intermittent fasting protects neurons from genetic and environmental stress factors during aging (R).
Intermittent fasting increases insulin sensitivity, which benefits neurons that stimulate the production of enzymes that help cells cope with stress and fight against disease (R).
Fasting can reduce issues with brain function and neurodegenerative disorders caused by inflammation (R).
7) Intermittent Fasting Can Prevent Chronic Degenerative Diseases
Fasting reduces inflammation and boosts cellular protection (R).
Intermittent fasting helps protect against obesity, diabetes, rheumatoid arthritis, hypertension, and asthma in humans (R).
Intermittent fasting protects against damage caused by an ischemic stroke (R).
Calorie restriction increase sirtuins and AMPK signaling, which help the body maintain internal stability (R).
8) Intermittent Fasting Heals Your Gut
Motilin and Ghrelin, which regulate the digestive tract, are released during fasting (R).
Ghrelin readies the body for the incoming nutrients by stimulating gastrointestinal motility and gastric acid secretions (R).
Studies show that there may be a therapeutic use for ghrelin in gastrointestinal inflammatory diseases like colitis and ischemia (R).
Fasting therapy has improved abdominal pain, diarrhea, nausea, and anxiety in patients with irritable bowel syndrome (R).
9) Intermittent Fasting Boosts Mood and Motivation
Studies show that fasting and calorie restriction improves anger, tension, confusion, and overall mood in aging males (R).
High levels of ghrelin are associated with anti-depressant effects (R).
10) Intermittent Fasting Is A Cognitive Enhancer
IF affect energy and oxygen radical metabolism, and cellular stress response systems, in ways that protect neurons against genetic and environmental factors to which they would otherwise succumb during aging (R).
Fasting increases the presence of drebrin, a protein that regulates neuronal development (R).
The loss of drebrin results in cognitive impairment that causes neurological disorders (R).
Intermittent fasting is associated with growth of the hippocampus, which is responsible for emotion and memory (R).
11) Fasting Reduces Inflammation
Fasting produces ghrelin in the body, which suppresses inflammation (R).
Intermittent fasting reduces pro-inflammatory cytokines and immune cells in the body (R).
Fasting for long intervals at night can reduce systemic inflammation (R).
Intermittent fasting reduces the risk for degenerative diseases connected to inflammatory response in the central nervous system (R).
12) Increased Ghrelin Levels May Slow the Onset of Parkinson’s Disease
Ghrelin increases the concentration of dopamine in an area of the brain where the decline of dopamine cells leads to Parkinson’s Disease (R).
13) Intermittent Fasting Improves Learning and Memory
A study demonstrated that mice on intermittent fasting had better learning and memory than mice with a regular eating schedule (R).
Studies suggest that learning may be best when the stomach is empty during the day because ghrelin levels are high (R).
14) Intermittent Fasting Protects Against Diabetes Risk
Intermittent fasting is associated with a reduced risk of diabetes (R).
15) Fasting Protects Against Autoimmune Disease
Fasting every three days has been effective in reducing autoimmunity and promoting regeneration (R).
Studies have shown that periods of fasting reversed symptoms of multiple sclerosis in animals (R).
Fasting prevents and improves systemic lupus erythematosus (R).
16) Intermittent Fasting Improves Sleep
Periods of fasting can lead to decreases in arousal during sleep (R).
Intermittent fasting has proven to benefit daytime performance and quality of sleep in non-obese individuals (R).
17) Intermittent Fasting Helps Protect Against Infections
Periods of food deprivation increases resistance to salmonella typhimurium infection because the body produces more IgA, which is critical in immune function (R).
Intermittent fasting promotes responses in the brain that suppress inflammation and maintain cognitive function during systemic bacterial infection (R).
Neutrophils have a preference to engulf refined carbohydrate (glucose, fructose, sucrose, honey and orange juice) over bacteria (R).
The neutrophil phagocytic capacity to engulf bacteria is affected when simple sugars are digested. And fasting strengthens the neutrophils phagocytic capacity to engulf bacteria (R).
However, the digestion of normal starches has no effect. The researchers concluded that the scientific data found that the function, and not the number of phagocytes in engulfing bacteria was altered by the ingestion of sugars (R).
18) Intermittent Fasting Allows You to Maintain Your Performance
Intermittent fasting has no effect on daily functioning and sports performance (R).
Intermittent fasting does not promote drowsiness or lack of vigilance (R).
This method of fasting preserves lean body mass (R).
The cellular effects of intermittent fasting are similar to the effects of physical exercise (R).
19) Intermittent Fasting Heals Your Skin
There is evidence that intermittent fasting may aid in skin wound healing (R).
Fasting has been effective in alleviating contact dermatitis and chronic urticaria (R).
The effects of intermittent fasting can assist with fighting acne (R).
20) Intermittent Fasting Helps Ease Chronic Pain
Intermittent fasting enhances neuroplasticity and learning in adults, which can aid in healing chronic pain (R).
My Recommendation On How To Do It
For most readers of this blog, I will recommend doing a restricted eating window from 8am to 6PM – that means eating only from 8am to 6PM.
You can also do the 5:2 protocol while you’re at it, which means to do a 24 hour fast two days a week (separated by at least one day).
Eat your normal diet five days a week. Pick any two days of the week to restrict your intake of food to fewer than 700 calories.
You will get the best results if your “normal diet” is a healthful one, but you do not need to try to restrict calories on your non-fast days.
For people with inflammatory issues, I’d recommend the Lectin Avoidance Diet.
This means that if your LDL receptors are problematic, you should be wary of intermittent fasting.
Who Shouldn’t Try Intermittent Fasting
- People with circadian rhythm issues
- People who have neuroendocrine issues and glutamate excitotoxicity, although following my approach will minimize the downside
- People who get hypoglycemic
- People who are severely underweight
- People who are trying to have a child
- People with hypercholesterolemia.
