You’ve probably heard of people doing ‘intermittent fasting’.
Some follow the popular 5:2 diet, while others might only eat within a specific window of the day.
Regardless of the method, essentially it all comes down to timing when you eat and monitoring calorie intake within those times.
What is intermittent fasting?
“Intermittent fasting is a general term used to describe a variety of approaches that change the normal timing of eating throughout a day, with short-term fasts used to improve overall health,” Dietitian Robbie Clark told Mamamia.
“In other words, the one consistent theme of intermittent fasting is that individuals periodically fast for a longer duration than the typical overnight fast that occurs while you sleep.”
The overall health benefits Clark refers to go way beyond weight loss (more on those later) but of course fat loss can be a result for those who are overweight. First, let’s take a little science lesson in what happens when we eat.
“When we eat, we ingest more food energy than our body can immediately use. As a result, this energy is stored away for later use,” Clark said.
“Enter the hormone, insulin. Insulin is the key hormone involved in the storage of food energy. To put it simply, insulin rises when we eat, helping to store the excess energy, known as glycogen, in the liver. There is, however, limited storage space, and once that is reached, the liver starts to turn the excess glucose into fat.”
