One of the biggest misconceptions about the no sugar diet is that it refrains you from taking any form of sugar at all.

The No sugar diet is simple – it cuts out artificial sugar but permits the intake of natural sugar from fruits and vegetables.

The best of all, you don’t need to count calories!

You can do the no sugar diet for as long as you like: 3 days, 5 days to 7 or 2 weeks. Maybe forever! You can start with small changes to make it more bearable or go cold turkey!

What Happens When You Stop Eating Sugar?

The sugar high we get from consuming sweet food is real.

Indulging in sweet treats causes a rapid spike of triglycerides in our bloodstreams. This leads to a drop in the good cholesterol known as HDL cholesterol.

Studies have shown that when you stop eating sugar, you can expect to feel withdrawal symptoms and effects similar to someone getting off drugs.

Physically, you may experience exhaustion, headaches, and brain fog. In extreme cases, some even suffer from gastrointestinal distress.

Emotionally, you may also be easily irritated and moody.

These withdrawal symptoms happen because your body has been used to the feel-good hormones sugar releases. And the lack of dopamine and serotonin makes you crave for more sugar to fix the hormonal void.

According to Dr. Robert Glatter, it is normal to feel cranky in the first few days of a sugar-free diet.

After a week or so, your body begins to adjust to the new levels of low glucose, dopamine, and serotonin. And from this point onwards, you will feel more alive and less irritable.

No Sugar Diet Benefits

The No sugar diet is super simple because all you need to do is to cut refined sugar.

That means it is easy to follow and it won’t restrict you from getting together with your friends out and about neither make it hard to prepare your meals and do your shopping. Did I mention you don’t need to count calories?

Get motivated by these 7 amazing health benefits the no sugar diet offers:

1. Younger Looking Skin

Sugar is an inflammatory food. According to the board-certified clinical dermatologist, Dr. Saya Obayan, when we consume too much sugar found in high glycemic index food, our insulin level spikes.

As a result, the sugar goes directly to our gut, entering our bloodstream and causing inflammation within our body.

Acne and flare-ups on your skin, rosacea, eczema, and psoriasis are some of the common signs of inflammation caused by excessive sugar intake according to this study.

Whether you suffer from any of the above conditions, expect great skin improvements going on this detox sugar-free journey.

2. Steady and Lasting Energy

Our body recognizes processed sugar as carbohydrates. Refined sugar enters our bloodstream fast, gets digested quickly, and gives you that additional boost of energy.

However, once your shot of sugar is metabolized, you’re in for a crash leaving you craving more sweets to fuel energy.

Your energy levels rise and plummet like a roller coaster through the day, and this becomes a vicious cycle.

On a no sugar diet you will get to eat protein-packed foods which will supply you with a steadier stream of energy so that you can power through your day efficiently.

3. Busting Abdominal Fat

Abdominal fat is hard to trim. And even more so as we age.

Sugary food triggers a flood of insulin through our body, which over time causes fat to accumulate around our abdomen according to this study.

Also known as visceral fat, these fat cells deep in the abdomen generate adipokines and adipose hormones.

These chemical troublemakers then travel to the organs and blood vessels, resulting in inflammation and other health conditions like heart disease and cancer.

Your belly fat won’t stand a chance on the no sugar diet.

Eating veggies, lean proteins, and plant-based fats will help you get a slimmer waistline.

4. Lose Weight

According to Professor David Ludwig, the professor of nutrition at the Harvard T.H School of Public Health, increased insulin levels do not only add pounds to your belly.

Instead, it transforms fat cells into a calorie-storage overdrive all over the body. Naturally, when you consume more sugar than your body needs, you will store the calories by converting them into fat and gaining more weight.

So by reducing your sugar intake and replacing them with healthy fats, your hunger pangs will decrease, your metabolic rate will speed up, and losing weight becomes easier without the yoyo effects.

Besides, you will able to maintain your weight loss better over time, rather than succumb to the binge-and-eat cycle triggered by the insulin rush.

5. Lower Risk of Diabetes

blood sugar levels

A diet overflowing with refined carbohydrates and sugar requires the pancreas to release lots of insulin, meal after meal, every day.

This extravagant demand puts insulin-producing cells into overdrive, causing them to malfunction and eventually leading to insulin resistance. When the body fails to maintain its normal blood glucose levels, this marks the onset of diabetes.

To prevent this, a no sugar diet will help to decrease body weight and finally the risk of type-2 diabetes.

6. Improved Cardiovascular Health

Did you know that you are twice as likely to die from heart disease if more than 25 percent of your daily calories are derived from sugar?

Research published in 2014 noted this positive correlation between excessive sugar consumption to an increased risk of death from cardiovascular disease (CVD).

In contrast, participants who derived 10 percent or less of their calories from sugar enjoyed a remarkably lower risk of cardiovascular-related diseases.

7. Improved Quality of Sleep

Halting your sugar intake will not solve your sleep problems overnight, but you should fall into a deeper sleep in the next few weeks.

Foods with high amounts of refined sugars reduce the degree of slow-wave sleep (SWS). SWS is important as the restorative sleep reinforces memories and information learned throughout the day.

Besides, sugar-laden food reduces the length of the rapid eye movement (REM) sleep stage, also known as the dream phase.

According to this study, eating high sugar, saturated fat foods are associated with sleep disorders.

So when you cut back on sugar in the long run, the quality of your sleep will improve. You may benefit from a longer REM and SWS period, waking up feeling rejuvenated the next morning.

Meal prepping has never been so important. The trick to stay on course is to always have your meals ready before the actual meal itself.

This is because when hunger strikes, you are more likely to reach out for an unhealthy snack.

Thus, plan your meals around 5 days ahead, and stock up for the week.

Most of us have 9 – 5 jobs, so time is rare. To prep your meals efficiently season your meat and store them in the freezer.

Clean your greens and chop your vegetables so that when you’re hungry, assembling your meal takes mere minutes. With food ready in a jiffy, you will be less tempted to reach for a cookie or a soda.

3. Read Labels

Once you have managed to cut out most sugar from your diet, it will be time to up your ante by eliminating food with artificial sweeteners.

You will have to master the art of reading nutrition labels.

Sugar comes in at least 61 different names so empower yourself with adequate knowledge to identify artificial sugar from natural sugar.

4. Have Simple Snacks Ready 

Keep easy-to-eat fruits on hand to satiate your urge with natural sweetness.

Fruits like bananas, papayas, cut melon, or citrus fruits are packed with fiber and healthy carbs to keep you full.

5. Cut Off Soda

Did you know that a 12-oz can of soda contains between 8 – 11 teaspoons (46.2 grams) of added sugar?

A single serving of soda is almost double the recommended daily sugar allowance. So swap your soda for plain water or tea to stay on course your no sugar diet.

1. Hypoglycemia

Following a diet too low in sugar or carbs can cause hypoglycemia, also known as low blood sugar.

According to the University of Maryland Medical Centre, low blood sugar can result in headaches, fatigue, and difficulty concentrating.

One common effect of hypoglycemia is the feeling of lightheadedness.

To prevent hypoglycemia, adopt a diet rich in whole grains, fruits, and vegetables.

This will ensure that your body is adequately fueled with a steady supply of healthy carbohydrates and sugars.

2. Flu-like Symptoms

Don’t be surprised if you feel more susceptible to flu-like symptoms.

This includes having a fever, chills, night sweats, diarrhea, and generalized fatigue.

It is also normal to experience dull aches and muscular pains that closely mimic the discomfort that accompany the flu.

Should you experience these flu-like symptoms when cutting back on sugar, do consult with your doctor or qualified healthcare provider to rule out flu as the cause of these symptoms.

3. Poor Sleep Quality

Sugar withdrawal can cause sleep disturbances just in the beginning.

The amount of REM sleep you get at night may be affected.

When the body tries to adjust to a decrease in sugar and certain hormones, your sleep quality could be affected.

Nevertheless, poor sleep quality related to sugar withdrawal will correct itself and diminish with time.

So before you get to enjoy a good night’s sleep, your body needs to adjust its blood sugar conditioned from its high to a lower, healthier state.

Nevertheless, if you notice that this persists for longer than a week or two, it’s time to consult with your physician for further advice.
