Is It Safe To Lose Weight With Intermittent Fasting?

Intermittent fasting is not a miracle diet or a passing trend.While the concept of fasting comes from time immemorial and most people are unaware of the potency of intermittent fasting, in recent years various alternatives, have emerged.The concept does need some explanation.There are many misconceptions even among those who have heard of it or have some rough idea about it. Let’s clear up those misconceptions first.

Intermittent fasting is not about what you eat. It’s not about low carbs or paleo diets. In fact, it has nothing to do with the food you eat. Intermittent fasting is not about starving yourself and surviving on air and water for days on end. It’s not an exercise technique either and there are no specific timings to this method.You are trying to lose weight, not end up emaciated and sick.

The Basics of Intermittent Fasting 

Intermittent fasting

The practice of fasting is known as the act of abstaining from all solid foods for a period of 24 hours or more.In the physiological context, fasting is a metabolic state in which a person who has not eaten overnight enters the acquired metabolic state after digestion and complete absorption of a meal.Intermittent fasting consists in cycling periods of fasting and non-fasting. Easily, it can be seen as a more flexible way to fast.

The concept was first mentioned by Martin Berkhan and it took the fitness world by storm. There are two windows for intermittent fasting.The first window is the eating window. This can be 8 hours, 6 hours or even a 4-hour window. During your eating window, you will need to consume all your daily requirement calories.

For example, if your daily calorie requirement, is  2000 calories , you will need to consume all your calories during this window. That means, whatever food you are going to eat for the day should be eaten during this window.

After that comes the fasting window. So, if your eating window is 8 hours, your fasting window will be 16 hours. This is based on a 24 hour day. If your eating window is 4 hours, your fasting window will be 20 hours. You are not supposed to consume any calories from food or drink during this period.

If you’re trying to lose weight, you should be at a caloric deficit of about  500 calories .The goal of intermittent fasting is to use the fasting window as a time where the body burns fat as fuel. Once your eating window is over, in a few hours, the food you have eaten would have been digested. The body will use this food as fuel for a while.

After that, since your stomach is empty, your body will have no choice but to use the stored fats as fuel to carry out all your bodily functions and also as energy. The interesting thing to note here is that even though you are fasting, your body is getting its daily calorie requirements. You’re not starving.Some people may worry that their insulin levels may spike the moment they start eating during their eating window. This will happen but it is not even an issue.Insulin spikes will not lead to weight gain while on the intermittent fasting program because your body will constantly be burning fat for fuel. So, cast your worries aside.

Fasting does not affect or reduce your muscle mass. A long-term fasting itself can reduce your muscle mass, but studies have attested muscle mass remained fully intact in fasting subjects after 48-72 hours and in this case we are proposing a fast of only 24 hours maximum.

Benefits of intermittent fasting:

Is intermittent fasting safe?

But what are the advantages of fasting? As the benefits of fasting are many, we will focus only on some of them.

It promotes the production of growth hormone (GH):

  • GH stimulates the growth, reproduction and cell regeneration in humans and other animals. It is considered one of the most important hormones in the body. Growth hormone slows the aging process; It promotes longevity. Studies have found that fasting can increase growth hormone  1,300% in women and nearly 2,000% in men  . Growth hormone is a metabolic hormone, which explains, in part, why fasting is so good for losing weight; It promotes fat burning, protects lean muscle and metabolic balance.

Insulin:

  • It has been shown that intermittent fasting causes important benefits for insulin resistance, thereby achieving lower blood sugar levels.
  • In proven human studies, fasting reduced blood glucose by 3- 6% while fasting insulin decreased between 20 and 31%.

Cellular repair:

  • When fasting, the cells initiate cellular repair processes. This includes  autophagy  in which cells digest and remove old and dysfunctional proteins that accumulate within cells.

Gene expression:

  • There are changes in the function related to longevity genes and protection against disease.

Side effects of Intermittent Fasting 

Hunger is among the main side effects. Other symptoms may include feeling weak and that your brain is not working as well as you might be used to. This is only temporary, as it may take some time for your body to adjust to the new meal schedule.

If you have a particular medical condition, you need to consult your doctor before trying intermittent fasting.

Intermittent Fasting for women

Some studies have found that fasting might not be as good for women as for men. One study found improved insulin sensitivity in men but blood sugar control in women worsened.Several women had reported presenting  amenorrhea  (lack of menstrual period) when they began intermittent fasting and returned to normal after they stopped it.Women should be careful with intermittent fasting. If you were to present amenorrhea stop it immediately.Women with fertility problems, pregnant or nursing women should not fast.

Intermittent fasting when combined with a clean diet and a progressive training regimen is unstoppable when it comes to fat loss. People who have struggled with stubborn body fat are stunned to see how fast their fat levels drop once they start intermittent fasting.
