Intermittent Fasting 101

What is intermittent fasting?

  • Intermittent fasting is a pattern of eating, not a diet. It is a way of scheduling your meals in a way that optimizes your body’s performance
  • It doesn’t restrict which foods to eat, but rather when you should eat it
  • There are several different intermittent fasting methods, all of which split the day or week into eating periods and fasting periods.

What happens during intermittent fasting?

  • Humans have been successfully fasting for thousands of years. Sometimes it was done out of necessity, in other instances, it was done out of religious reasons – various religions including Islam, Christianity, Buddhism, mandate fasting in some form. Moreover, humans and animals often fast instinctively while sick. There is nothing “unnatural” about fasting and our bodies are fully equipped to handle extended periods of not eating
  • After eating a meal, our bodies release insulin. However, it isn’t meant to be released all the time and high levels of insulin make it hard for our bodies to burn fat. Which is why eating small meals throughout the day doesn’t really help with weight loss
  • While we fast, we are letting our insulin levels go back to normal so that we can unlock our fat stores and start burning fat and losing weight! Most people enter the fasted state about 8-12 hours after their last meal.
