What is ‘Intermittent Fasting’ ?

Intermittent fasting has recently become a health trend. It’s claimed to cause weight loss, improve metabolic health, and perhaps even extend lifespan.

Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It doesn’t specify which foods you should eat but rather when you should eat them. Common intermittent fasting methods involve daily 16-hour fasts or fasting for 24 hours, twice per week.

Intermittent Fasting Methods

There are several different ways of doing intermittent fasting — all of which involve splitting the day or week into eating and fasting periods.

These are the most popular methods

  • The 16/8 method: Also called the Leangains protocol, it involves skipping breakfast and restricting your daily eating period to 8 hours, such as 1–9 p.m. Then you fast for 16 hours in between.
  • Eat-Stop-Eat: This involves fasting for 24 hours, once or twice a week, for example by not eating from dinner one day until dinner the next day
  • The 5:2 diet: With this methods, you consume only 500–600 calories on two non-consecutive days of the week, but eat normally the other 5 days.

Health Benefits

Many studies have been done on intermittent fasting, in both animals and humans. Here are the main health benefits of Intermittent Fasting.

  • Weight loss: As mentioned above, intermittent fasting can help you lose weight and belly fat, without having to consciously restrict calories.
  • Insulin resistance: Intermittent fasting can reduce insulin resistance, lowering blood sugar by 3–6% and fasting insulin levels by 20–31%, which should protect against type 2 diabetes 
  • Inflammation: Some studies show reductions in markers of inflammation, a key driver of many chronic diseases 
  • Heart health: Intermittent fasting may reduce “bad” LDL cholesterol, blood triglycerides, inflammatory markers, blood sugar and insulin resistance — all risk factors for heart disease
