A simulation has shown how your body goes through both physical and mental changes as you attempt to quit sugar for seven days.

While having a sweet treat now and again is perfectly fine, many people get into an unhealthy habit of consuming lots of sugar regularly.

To combat this, you might think it would be an easy and quit fix to simply cut all sugary foods out of your diet, but this really isn’t as easy as it sounds.

A simulation on the YouTube page Untold_Healing revealed that both physical and mental changes can happen to the body, ultimately making cutting out sugar a more difficult task than many would imagine.

Despite the difficulties, managing the amount of sugar you consume can help prevent diabetes, obesity and a slew of other medical conditions, so all in all, it might be worth giving it a go.

The video narrator of the simulation broke down how the body reacts over the first seven days.

Days one and two without sugar

This is when the cravings hit hard, the simulation explains.

"Headaches, mood swings and fatigue, your body is literally going through withdrawal."

Days three and four without sugar

This is when the fog lifts, energy becomes more stable, and there'll be no more 3 p.m. crashes.

Days five to seven without sugar

Your skin will start to clear up, there'll be less inflammation, reduced breakouts and that puffy look will be gone.

"Bonus, you’ll sleep better and stop craving sweets as intensely," the video adds.

"Most people don’t realize they are eating 17 teaspoons of added sugar daily, three times the recommended amount."

The points raised in the video are also supported by experts at the rehab center Addiction Help.

They note that while cutting sugar out or reducing it in your diet can be beneficial, it can prove difficult for some people due to how the relationship with sugar impacts brain chemistry.

The organization stated: "Sugar consumption can have a powerful effect on the brain’s production of dopamine, a neurotransmitter strongly associated with feelings of pleasure and reward."

Taking in a large amount of sugar releases dopamine, which can lead to dependence.

“For individuals with a dependence on or addiction to sugar, lowering sugar intake can lead to many unpleasant withdrawal symptoms.”

Highlighting some of the most prevalent symptoms people go through, they added: "Common symptoms in the early stages of sugar withdrawal include physical symptoms like headaches, fatigue, and nausea.

"Mental symptoms include irritability, anxiety, mood swings, and generally worsened mental health.

“The important thing is to stick with whatever diet change you make. Some people try and fail to cut sugar completely, thus going through rounds of withdrawal, relapse, and withdrawal.

"If you find it difficult to do a complete sugar detox, try slowly eliminating sugar or a low-sugar diet."
