We live in a world in which food is everywhere. We used to limit our meals only at home and the dinnertable. But, now, we made the food so easily accessible that we don't have to limit ourselves to eat at home anymore. In fact, think about it: where do you NOT eat? Food is so convenient now that you can eat anywhere you like (at home, at the office, at the movie theater, in a class, etc.)
Over consumption of food leads to obesity and insulin resistance.
Your body is working so hard to keep up with the constant overload of food that at one point, it cannot do it anymore. Your hormonal balance is a wreck, and you can't function anymore.
What does your body need?
As difficult as you may think, your body only wants to: REST.
If you are eating all the time, then your body can't keep up. When you are fasting, you are giving your body time to rest and to make sure all your hormones are balanced. This practice is NOT new. We used to do this all the time. Remember, there was a life before refrigerators and microwaves.
Who should consider IF?
If you are suffering from obesity and insulin resistance (diabetes, PCOS, heart disease, liver disease, Alzheimer's, etc.), then incorporating intermittent fasting into your life may be a good idea.
Does this mean that if you are not in one of those categories, then you shouldn't do intermittent fasting? No, it means that if you are a healthy person, you could still get the benefits of intermittent fasting, but you won't probably have a goal to reach.
If you are thinking about including intermittent fasting in your routine, please consult with somebody, especially if you are taking medications or if you have a chronic condition.
