What is fasting? Why we need to fast?

Why we eat everytime we go outside? Is it because of the desire which we are unable to control and eat unconsciously?.



Gandhi ji use to fast very often. By the habit of fasting he made India independent and we are unable to fast for 1 day. It is because our we do not have control over our urges which makes us unhealthy. Many people use to fast due to spiritual pursuits it is healthy to fast. Many scientists have confirmed fasting help in many ways

What exactly is fasting?

First we need to define what fasting means, and what time restricted eating means. Time Restricted Eating (TRE), means eating only in a specific time window, and not eating the rest of the day. For instance 18:6 means not eating for 18 hours straight, then eating over a 6-hour period. This can be 12:12, 16:8, 18:6 or even 22:2. They key is that you have an extended period of time each day when you are not consuming calories.

More extensive fasts, 24-72 hours or even longer, are really what we refer to when we say intermittent fasting. For this explanation, I will refer to extended fasts and TRE together as they have similar benefits. I will explore the differences and go into more scientific detail in a future post.

Here are the top 5 reasons we should all fast

1.    Fasting is the most efficient way to lose weight.

Forget the fat burning foods, forget the cleanses and detoxes. Not eating is the key to losing weight. But do it intermittently. That’s why it’s called intermittent fasting. Chronic calorie restriction doesn’t work long term since it forces our bodies to reduce our resting metabolic rate (RMR), thus stalling weight loss and increasing frustration. Intermittent calorie restriction, on the other hand, allows for weight loss without changing our RMR, the key to healthy and successful long-term weight loss.

2.    IF is a great way to lower insulin.

It just makes sense. If there is no food coming in, there is no need for insulin to rise. Insulin will stay at its low steady basal rate, and there will be no elevations or spikes. That keeps the area under the curve low, right where we want it. Low insulin means we can mobilize our fat stores, and possibly more importantly, it protects us from the harmful long-term effects of hyperinsulinemia.

3.    Intermittent Fasting is the key to longevity.

The one consistent finding in longevity research, from single cell organisms up to primates, is that calorie restriction works. But as we have learned from chronic calorie restriction experiments in humans, it’s not so clear cut. First, its miserable and most people would rather die younger that live longer with chronic calorie restriction. Agree?

Second, our bodies adapt to chronic calorie restriction and thus make it difficult to maintain the health benefits. Intermittent calorie restriction, on the other hand, has the promise of all the longevity benefits without all the baggage that comes with it. The fountain of youth only helps if we like how it tastes.

4.    It’s easy!

What’s easier than skipping breakfast? No planning, no shopping, no cooking, no cleaning. Simply walk out the door.  In our hectic everyday lives, we should welcome anything that takes less time and makes our lives a little easier. Fasting does exactly that. Just make sure you bring a water bottle with you wherever you go, and maybe some sea salt to put in your water. Stay well hydrated and enjoy the simplicity.

5.    There are many ways to make fasting work for you.

 There is more than one way to have a successful fast. As mentioned previously, 18:6 can work wonders for most people. For those who are more adventurous, a 72-hour water fast can have amazing results. And there is everything in between. Just follow the simple rules of staying hydrated, paying attention to how you feel, avoiding anything with calories, and even avoiding calorie-free sweeteners. The rest of the details can be individualized to fit your life and your goals.

The Top Reason Why You shouldn’t fast

Fasting can work wonders for most people, but it can also be dangerous for others. If you take medications for diabetes, hypertension or other medical conditions and you’re trying to fast on your own, don’t do it! Fasting can cause significant harm in these circumstances if not done with proper precaution. That doesn’t mean it can’t be done. In fact, it can still be incredibly beneficial. Just make sure you are working with an experienced clinician who can help coach you through it safely.
