The Nicotine Connection: Why Shisha Seems to Curb Hunger
At the core of the appetite suppression claim is nicotine, the addictive chemical found in tobacco. Nicotine is a stimulant that interacts with the body's nervous system in several ways that can influence appetite. Research shows it can act as a short-term appetite suppressant and slightly increase metabolic rate, primarily by activating specific pathways in the brain's hypothalamus that regulate hunger and fullness. These effects, however, are complex and not fully understood.
How nicotine affects your hunger signals:
- Impacts Neurotransmitters: Nicotine can trigger the release of neurotransmitters like dopamine and norepinephrine, which can temporarily reduce the brain's reward response to food, making it less satisfying.
- Hormonal Influence: It affects the hormones that control hunger, like ghrelin (the 'hunger hormone') and leptin (the 'fullness hormone'), potentially tilting the balance toward feeling less hungry.
- Metabolic Boost: Nicotine can cause a slight, short-term increase in metabolic rate, leading to a marginal increase in calories burned at rest.
The Paradox: Why Shisha Smokers Often Experience Weight Gain
Despite the appetite-suppressing effects of nicotine, scientific evidence shows a strong association between chronic shisha use and a higher prevalence of obesity. This seemingly contradictory finding reveals that the act of shisha smoking involves much more than just nicotine intake.
Several factors contribute to this outcome:
- Sedentary Lifestyle: A typical shisha session can last for an hour or more, requiring the user to remain seated. This prolonged sedentary behavior, especially if repeated daily, significantly reduces overall energy expenditure.
- Social Eating Patterns: Shisha is often smoked in social settings, such as cafes or restaurants, which are rich in eating stimuli. The prolonged sessions increase exposure to and consumption of high-calorie foods and sugary drinks, negating any minimal appetite suppression from nicotine.
- Taste and Smell Effects: While smoking, the sense of taste and smell can be dulled. When individuals quit smoking, these senses often improve dramatically, making food more appealing and potentially leading to increased intake.
Comparison: Shisha vs. Cigarettes and Health Outcomes
To understand the full health impact, it's helpful to compare shisha with conventional cigarettes. Many people wrongly believe shisha is less harmful because the smoke is passed through water, but this is a dangerous myth.
| Feature | Cigarettes | Shisha/Hookah | Outcome on Weight & Health |
|---|---|---|---|
| Nicotine Intake | Delivers nicotine in shorter, more frequent bursts. | Delivers a significant, larger dose of nicotine over a single, long session (equal to 100-200+ cigarettes). | Nicotine suppresses appetite, but the dosage and duration vary. |
| Toxic Chemicals | Contains thousands of toxic chemicals, including tar, carcinogens, and heavy metals. | Contains many of the same toxins, plus high levels of carbon monoxide from the charcoal, and the water does not filter them out. | High toxicity leads to significant long-term health risks, including cancer and cardiovascular disease. |
| Duration of Session | A session lasts only a few minutes. | A single session typically lasts 45-60 minutes, and sometimes longer. | Long sessions promote sedentary behavior, countering any appetite suppression. |
| Social Context | Often a quick, individual habit. | Primarily a social activity, often paired with high-calorie eating and drinking in cafes. | Increases exposure to food-related stimuli and sedentary behavior, leading to a higher risk of obesity. |
| Obesity Risk | Associated with lower body weight in some studies, but with serious health trade-offs. | Studies show a higher risk of obesity and metabolic syndrome despite nicotine's effects. | The lifestyle factors and prolonged exposure to toxins in shisha appear to override nicotine's appetite-suppressing effects, leading to obesity. |
The Risks of Using Shisha Outweigh Any Perceived Benefits
Using shisha for appetite suppression or weight management is an extremely dangerous and ineffective strategy. The health risks are severe and well-documented. Shisha smoke, whether from tobacco or so-called 'herbal' products, contains an array of harmful substances, including cancer-causing chemicals. The long-term consequences far eclipse any minimal, temporary appetite-curbing effect.
- Infections: Sharing mouthpieces can spread infectious diseases like herpes, hepatitis, tuberculosis, and COVID-19.
- Cardiovascular Disease: The nicotine and carbon monoxide increase heart rate and blood pressure, significantly raising the risk of heart disease.
- Cancer: Shisha smoking has been linked to various cancers, including lung, oral, and esophageal.
- Dependency: Nicotine is highly addictive, and developing a dependence can be a powerful barrier to quitting.
- Obesity Risk: As demonstrated, the social and lifestyle factors associated with shisha can actively promote weight gain over time, despite the nicotine content.

Conclusion
While shisha contains nicotine, a substance known to suppress appetite, this effect is minimal and ultimately overpowered by the negative health and lifestyle consequences associated with waterpipe use. Chronic shisha smoking is linked to a higher prevalence of obesity, likely due to the prolonged sedentary sessions and social context of consuming high-calorie foods. Pursuing shisha as a weight management tool is misguided and dangerous. The significant health risks, including cardiovascular disease, cancer, and addiction, far outweigh any perceived or temporary appetite-suppressing benefit. For sustainable and safe weight management, a balanced diet and regular exercise are the only medically recommended paths.
