Intermittent fasting is a term for various diet plans that alternate between fasting and non-fasting periods. Some preliminary research assess that intermittent fasting can produce sustainable weight loss compare to long-term calorie restriction.
Fasting has been a practice throughout human evolution. Ancient hunter-gatherers couldn’t find anything to eat sometimes, and evolved to be able to function without food for extended periods of time. It could actually be more natural than eating 3 meals a day.
Fasting is also often done for spiritual reasons like in Islam, Christianity, Judaism and Buddhism.
Intermittent fasting focuses more on when you eat than on what you eat (even if that’s very important too). Beverages are allowed like water, coffee or tea. Physical exercise can be practice and can be beneficial.
The 2 most common intermittent fasting methods involve :
– 16/8 method :
Daily 16hrs fasts. Reducing your eating window period. Eating from 10 am to 6pm. It usually means skipping breakfast, having a light dish at 10am, a main meal by 12pm and dinner before 6pm (healthy snacks are OK if necessary)
– Eat-Stop-Eat : 24-hour fasting twice a week.
The 16/8 method, is the most sustainable one as it does not involve calorie restrictions.
Note : There is not calorie restriction here ! Eat healthy and as many calories as you would eat on a normal diet

Side effects of intermittent fasting
Intermittent fasting may not be beneficial for everyone. As mentioned above, if you are underweight, pregnant, breastfeeding, with irregular periods, infertility issues or if you have previous eating disorders, intermittent fasting might not be for you.
Men tend to do better on intermittent fasting due to their insulin sensitivity. Some women’s periods can be stopped before restarting after they go back to their previous eating patterns.
