What Is A No-Carb Diet?

Zero carb diet is just like what it sounds- it is a diet that restricts the use of carbohydrates and keeps it as low as possible. It might be similar to an Atkins or keto diet but there are differences. The Atkins diet restricts the users to consume only 20 to 100 gm carbs a day. The aspect of net carb is an important factor in this case.  The Keto diet is another approach that restricts carb intake to 50 gm or less per day. The Keto diet emphasizes consuming high amounts of fat and medium protein consumption.

The zero-carb diet aims for the users to go on carbohydrate deficit food. But it does not have any detailed procedures on protein vs fat intake amount. The blog will provide a detailed approach to 3 days of a carb diet.

Knowledge Is The Key

Knowledge Is The Key

Before you switch to no carbs for 3 days for weight loss, there are things you must know about carbs. Refined carbohydrate-rich foods like bread, pasta, and white rice work like fossil fuels. Why they are so popular is because they are cheaper and contain lots of energy. However, the scientific consensus is that over-relying on refined carbohydrates will have a bad ending just like fossil fuels.

As many people are interested in eliminating carbs from their diet to lose weight fast, there are some depths behind the idea. Anecdotal and scientific researches reflect that the strategy is good and can help to drop pounds. But carbohydrates are not only found in foods discussed above. Carbohydrate is a nutrient that is hidden in fruits, vegetables, nuts, milk, legumes, and others. As this is the case, it is practically inconceivable to cut curbs and make them zero.

The idea in this case is to discard the refined carbs and limit the intake of good or complex carbs named above and consume butter, bacon, and bourbon as per your liking.

Here are the effects which you might feel when you start a 3-day no-carb program.

1. Experiencing Low-Carb Flu

Experiencing low-carb flu

When you are going for a no-carbs weight loss program, your body energy generating patterns will change as the intake of nutrients will change. There will be an initial slew of unpleasant experiences through side effects which will feel like you are facing something nasty. In the worst side effects, you might experience fatigue, weakness, dizziness, headaches, irritation, and nausea which can last for a few days or a few weeks.

The human body follows a fuel hierarchy. When given the choice the body automatically stores glucose and stores glycogen first and fat follows it. But if the chain of fuel intake breaks, the body will start burning muscles by cannibalizing. The body is intelligent enough to create its favorite food if any supply is not provided. The process is known as gluconeogenesis and it takes place when carbs are depleted and protein remains high. In this situation, the liver will draw amino acids from protein and develop glucose from it. It is evidence of how much the body is fond of glucose.

When your no-carb no sugar diet becomes a habit, after a few days, the body goes into a state of ketosis. In the process, small carbon fragments called ketones are released in the blood as the body is burning fat instead of carbohydrate. Going into ketosis does not assure loads of energy which is touted as one of its many benefits.

But one thing is sure the adaptive period of zero carb diet can be uncomfortable. Your body might feel like there is less gas in the tank when involved in physical activities. The body will start running on ketones which will be achieved by bursting the fat cells. Fat is a comparatively slower form of fuel compared to glucose. However, you might not feel anything for three days. The body takes time to recognize the changes in diet patterns.  

2. The Body Will Lose Water Weight First

As you will begin with the weight loss no carbs program, the first thing which will happen is if pants will be getting loose immediately. A three-day program might not show the same result but it will take more than 3 days to feel the results.  

The major reason behind this change is that water weight will be shaded first as carbs hold a lot of water. Food is a rich source of water that is absorbed by the body. The other reason is that when glucose will be gone, the body will look for stored glucose forms. The stored form is known as glycogen and when it metabolizes it uses water. It is a reason why on a low-carb diet, the body water is lost first. The loss is because the stored glycogen is releasing water.

But you must not be satisfied or feel discounted due to lack of results. You must be patient to go ahead with the no-carb program. Water loss in a low-carb diet can be significant. There can be up to five, ten, or fifteen pounds in many cases. It must keep you motivated to stick to the program and maintain your workout effectively. Take it as a preview of changes that can happen once you are dedicated to doing something good for your body.

3. Fat Burning Results?

Fat burning results

Studies by the British Journal of Nutrition concluded that people who were given a low-carb ketogenic diet had the most weight loss in the long term compared to a low-fat diet. The study suggested that low-carb diets can be an efficient tool that can help to bring down the rate of obesity. Once the water weight is reduced, it will slowly start burning the fat stored in the body to draw energy. This is where the production phase for the weight loss no carb approach starts. You will feel the results of fat burning when the body will deplete the water weight in the body. The aim is to deplete the intake of carbs so that the body starts cannibalizing the fat stored in the body to draw energy.

4. Bad Breath

Bad Breath

Though prevalent among a few people, ketones released in the body which fuel a keto-adapted body are released through the breath which can smell like acetone or rotten fruit. The other reason for bad breath is persistent dry mouth due to lack of water.  Hence, this situation can be a reason why there can be bad breath.

Mind The Downsides

Mind The Downsides

Consuming a variety of food is the best approach to ensure that all the nutrients are supplied to the body as per its need. For example, plant-based food will provide you with a rich source of vitamins, and minerals like vitamin C, potassium, and many B vitamins.

Elimination of plant-based food will make it harder for the body to find each of its important nutrients.  Hence, there is a chance that the body will go into a nutrition deficit phase. Besides, a no-carbs diet is very low in fiber which is important for the regulation of digestion. Lack of fiber will bring deficiency in terms of healthy gut bacteria and cholesterol management. Therefore, a high intake of fiber is associated with a low risk of heart disease and cancer.

No-carb diets, like any other restrictive diets, eventually develop to foster an unhealthy relationship with food. It forces someone down a path of disorderly eating. Eating disorders are among the mental health issues which have the highest mortality rate. People who have eating disorders are not to follow this type of diet.
