Sugar's Impact on Your Health: The Real Deal Behind Sweets
Abandoning Sugar: Its Benefits for Your Health - The Undeniable Advantages of Eliminating Sugar Consumption from Your Diet
By Tina Pokern+ - 4 Min
Indulge in a piece of candy, a scrumptious slice of cake, or a cool scoop of ice cream - sweet treats bring instant gratification, lifting our moods and providing a burst of energy. But the effects are fleeting, and consuming too much sugar can lead to a host of health problems such as diabetes, obesity, Alzheimer's, and depression. This is what you should know about sugar and the impact of its restriction on your health.
Is Sugar Addictive?
The trend of sugar restriction is gaining momentum in social media, blogs, and YouTube, with people sharing their detox experiences. They discuss the onset of pounding headaches and extreme fatigue in the beginning, but also report increased energy and better sleep after several days without sugar. But is this the reality?
Whether sugar is addictive is a contentious topic among scientists. There are factors that argue against addiction, but evidence shows that sugar activates our brain's reward system, triggering the release of dopamine, popularly known as the happiness hormone. This surge in dopamine levels temporarily improves our mood, with a pronounced decline affecting our wellbeing afterwards.
Short-lived Highs and Energy Losses
Sugar consumption can cause a temporary sugar high due to elevated blood sugar levels, making us more alert and enhancing our mood. The regulation of blood sugar levels is achieved by the release of insulin. However, a sudden increase in blood sugar levels, as often occurs from consuming sugary products such as sodas, leads to a spike in blood sugar, followed by a higher release of insulin and a rapid decrease in blood sugar levels. This can sometimes cause us to plummet below our normal levels, leading to feelings of stress and hunger, colloquially known as "hangry."
But the biggest challenge comes when we switch to a sugar-free diet. Our body requires time to adapt to this change, and in the beginning, we may feel tired and generally unwell.
Short-term and Long-term Effects of Sugar Avoidance
We Taste Differently
In a matter of days, the brain adapts to the altered sugar consumption. This change affects taste perception, making it more refined and intensifying our perception of sweetness even in small amounts. The longer one avoids sugar, the greater this effect. Those who previously consumed a lot of sugar are more sensitive to this change than those who have already consumed less.
Better Breath
Mouth bacteria thrive on sugar, making it their primary source of nutrition. When denied sugar, their reproduction is also reduced, leading to fresher breath.
Dropping Blood Pressure
In the first two weeks, there is a reduction in blood pressure. The severity of this effect depends on the previous sugar consumption. Some may not notice a lower blood pressure at all, while others may feel weak and tired during this time. However, sugar avoidance can eventually lead to an energy boost and better sleep.
Weight Loss
Avoiding sugar can promote weight loss, observable even after a week. Studies have pointed to this effect, as insulin, released in response to blood sugar levels, blocks fat burning. By avoiding sugar, you prevent a rapid and strong increase in blood sugar levels, minimizing the insulin release and thereby facilitating fat burning.
Reduced Inflammation
Research has shown that sugar consumption can lead to an increase in some inflammation values in the blood, which decreases when sugar avoidance is implemented. This means that reducing sugar intake can help reduce inflammation in the body.
Recovery and Improvement
After ten to 14 days, it can be observed that the body is recovering, leading to the alleviation of physical complaints associated with excessive sugar consumption, such as fatty liver or insulin resistance.
But Wait, Short-term Aberration Isn't the Answer
A short-term drastic avoidance of sugar does not offer long-term health benefits. Going sugar-free for seven days is commendable, but if we return to our previous sugar consumption levels afterwards, we've gained nothing. Permanently lowering sugar consumption through dietary adjustments is a sounder approach.

Overall:
The scientific consensus on sugar’s addictive properties and its health effects continues to evolve, but several robust findings have emerged from recent literature.
Addictive Properties of Sugar
- Evidence for Addiction-like Behavior: Studies suggest that sugar can trigger brain reward pathways similar to addictive substances, leading to compulsive consumption and cravings in some individuals[2][3]. However, not everyone is equally susceptible, and the addiction-like response is more pronounced in animal models or in specific populations, such as those with eating disorders or a predisposition to food addiction[3].
- Human Evidence and Controversy: In humans, while there is evidence of sugar cravings and behavioral patterns resembling addiction—especially in the context of food addiction and eating disorders—the broader scientific community does not universally classify sugar as an addictive substance in the same way as alcohol or nicotine[2][3]. Food addiction is recognized, but its prevalence varies widely, and sugar is only one component of the problem[3].
Short-term Health Effects
- Blood Sugar Fluctuations: High sugar intake can cause rapid spikes and drops in blood glucose, leading to energy crashes and increased hunger[4][5].
- Mood and Mental Health: There is evidence linking greater consumption of sugar-sweetened beverages to increased risks of depression over short observation periods[5].
- Dental Health: Sugar is a primary contributor to dental caries, with effects observable even after short-term exposure[5].
Long-term Health Effects
- Metabolic Health: Long-term high intake of sugar, especially from sugar-sweetened beverages, is associated with increased risks of type 2 diabetes, nonalcoholic fatty liver disease, and obesity[5].
- Cardiovascular Disease: There is convincing evidence for a direct association between sugar consumption and increased risk of cardiovascular disease and coronary heart disease[5].
- Other Conditions: Greater sugar-sweetened beverage consumption has also been linked to higher risks of depression (long-term), all-cause mortality, and possibly some cancers, although evidence for cancer remains more limited and warrants further research[1][5].
- Gout and Kidney Health: Elevated uric acid concentrations and increased risk of nephrolithiasis (kidney stones) are also associated with higher sugar intake[5].
Summary Table
| Aspect | Short-term Effects | Long-term Effects ||-----------------------|-------------------------------------|-------------------------------------------|| Brain/Reward Response | Cravings, compulsion in some | Food addiction, especially in at-risk groups[3] || Mood/Mental Health | Depression risk (short-term) | Depression, mood disorders[5] || Metabolic Health | Glucose spikes, hunger | Diabetes, obesity, fatty liver[5] || Cardiovascular | – | Heart disease, all-cause mortality[5] || Kidney | – | Uric acid, nephrolithiasis[5] || Dental | Cavities, enamel erosion | Chronic dental decay[5] || Cancer | – | Limited but possible associations[1][5] |
Conclusion
While sugar is not classified as a classic addictive drug for the general population, it can trigger addiction-like behaviors in susceptible individuals. Short-term effects include blood sugar fluctuations, mood changes, and dental issues. Long-term effects include increased risks of metabolic, cardiovascular, and possibly some other diseases. Consensus is strongest regarding the risks of sugar-sweetened beverages for obesity, diabetes, heart disease, and dental health[1][5]. Evidence for cancer is more limited, but ongoing research is warranted[1].
- The scientific community is still debating the addictive properties of sugar, but it is known that sugar activates the brain's reward system, releasing dopamine, also known as the happiness hormone.
- In a sugar-restricted diet, the brain adapts to the change, making taste perception more refined and intensifying the perception of sweetness even in small amounts.
- After two weeks of avoiding sugar, there is a reduction in blood pressure, with the severity of this effect depending on the previous sugar consumption.
- Reducing sugar intake can promote weight loss, leading to an energy boost and better sleep in the long run, as insulin, released in response to blood sugar levels, blocks fat burning.
