3 types of fasting

• Time-Restricted Feeding
  This is the process of limiting calorie intake to a specific timeframe that aligns with our circadian rhythm. Circadian rhythm is often referred to as our “body clock”, the natural cycle that tells our bodies when to sleep, rise, eat, and more. Eating meals only during an 8 to 12 hour period each day while fasting — between 10 a.m. to 6 p.m., for instance — is an example of aligning with our circadian rhythm. Body systems work better when synchronized with one another; midnight snacking when our body usually sleeps throws our natural repair system out of sync. In addition, giving our bodies more time to repair is beneficial for our health.

• Intermittent Calorie Restriction
  The practice of reducing the number of calories consumed in a day. Research has focused on a two-day diet where calories are reduced in half and carbohydrates are limited for two consecutive days in a week. This approach puts the body through short and intensive therapy. The intermittent calorie restriction approach also reminds us that we do not need to consume constantly. When we do consume we can choose wisely and continue normal activities and exercise with reduced fuel.

• Periodic Fasting with Fasting Mimicking Diets
  This means limiting calorie intake for three to five days, prompting the cells to deplete glycogen stores and begin ketosis. While this can be done without eating food, it isn’t considered the safest option. A specific five-day calorie-limited diet (around 1,000 calories per day) is sufficient to mimic fasting without depleting nutrients. It is speculated that this method is superior to the two-day fast, allowing the body to enter ketosis and begin a true cleanse.
