Overview of intermittent fasting

Intermittent fasting is when you alternate between periods of eating and fasting. This type of eating is often described as “patterns” or “cycles” of fasting. Intermittent fasting isn’t about starving yourself — it’s about cutting way back on calories for short time periods. The belief is that your body becomes satisfied with smaller portions while also reducing cravings for unhealthy snack foods. That is, as long as you maintain a healthy diet while trying it all out.

What it 5:2 intermittent fasting?

The 5:2 diet involves eating a normal, healthy diet for five days every week and 'fasting' on the remaining two days. On a ‘fast’ day, you would typically consume between 500 and 600 calories.

Many diets focus on what to eat, but intermittent fasting is all about when you eat. With intermittent fasting, you only eat during a specific time. Research shows fasting for a certain number of hours each day or eating just one meal a couple days a week may have health benefits - for example for loosing weight and for better control of diabetes.
