Nicotine: What We Know About Its Effects on Appetite and Brain

Some people talk about nicotine helping with weight and memory. But doctors warn it is not safe for losing weight. More research is needed to know if it's good for the brain. We do not know all the risks of using nicotine without smoking.
By Newsroom | Health, Science |

A conversation is emerging around nicotine, not solely as an addictive substance, but as something that may affect appetite, metabolism, and cognitive function. This discussion is amplified by the growing popularity of products like Zyn, which deliver nicotine without smoking.

Recent reports and online discussions suggest nicotine might have a role in weight management, by possibly reducing appetite and increasing metabolism. Furthermore, research is exploring nicotine's potential to aid in memory improvement and cognitive function, particularly in individuals experiencing cognitive decline. However, medical experts caution that nicotine is not a safe or proven method for weight loss, and the long-term health impacts of non-smoking nicotine use are not fully understood.

Timeline and Key Developments

The understanding of nicotine's effects has evolved over time. While traditionally associated with smoking and its well-documented harms, newer research and product trends are shifting the focus.

  • Long-term Research: Dr. Paul Newhouse has studied nicotine for over 30 years, investigating its impact on memory and cognitive function.

  • Emerging Product Trends: The rise in popularity of products like Zyn pouches has brought renewed attention to nicotine's stimulant effects and potential side effects, including appetite suppression.

  • Ongoing Studies: Current research, such as the MIND study, examines nicotine's effects on memory and cognitive impairment. New projects are exploring its potential use in treating long COVID and late-life depression.

  • Public Discourse: Online platforms and articles are discussing these potential benefits, sometimes generating hype around nicotine as a weight-loss aid.

Nicotine and Weight Management: A Dual Narrative

There's a palpable tension between anecdotal reports and expert warnings regarding nicotine's influence on body weight.

  • Reported Appetite Suppression: Some users of nicotine products, such as Zyn, report experiencing a reduction in appetite, which they link to weight loss.

  • Metabolic Effects: Nicotine is understood to potentially suppress appetite and increase metabolism. However, the extent and consistency of these effects vary among individuals.

  • Expert Caution: Medical professionals emphasize that nicotine is not a safe or reliable strategy for weight management. The long-term health consequences of using nicotine for this purpose are largely unknown.

  • Weight Gain Upon Quitting: It is also noted that quitting nicotine can lead to weight gain for some individuals.

Cognitive Function: Research into Potential Benefits

Beyond weight, nicotine is being examined for its effects on the brain, particularly concerning memory and cognitive abilities.

  • MIND Study: Dr. Paul Newhouse's research, including the MIND study, specifically investigates if nicotine can enhance memory and cognitive function in individuals with mild memory loss or cognitive impairment.

  • Broader Cognitive Research: Studies are also looking into nicotine's potential in addressing cognitive challenges related to Alzheimer's disease and late-life depression.

  • Long COVID Research: Nicotine is being explored as a potential treatment for some aspects of long COVID, including cognitive symptoms.

It is crucial to differentiate nicotine from other compounds that might be mentioned in discussions of aging and health, such as NMN.

  • Nicotine: A stimulant chemical found in tobacco, which is being studied for its effects on appetite and cognition.

  • NMN (Nicotinamide Mononucleotide): A compound being researched for its role in producing NAD, which declines with age and is associated with age-related health concerns. While NMN is linked to cellular processes and aging, it is distinct from nicotine and its immediate physiological effects.

Expert Perspectives and Caveats

Leading researchers and medical professionals offer nuanced views on nicotine's potential and its risks.

"Medical experts say we understand very little about how safe nicotine is for weight loss. But she emphasized that that didn't mean people should use nicotine as a weight-loss aid."- Business Insider, quoting a medical expert

Dr. Paul Newhouse's extensive work highlights a scientific interest in nicotine's therapeutic possibilities, separate from its addictive nature when smoked. However, this research occurs within controlled study environments, distinct from the self-administration of nicotine via various products.

Conclusion and Implications

The current discourse surrounding nicotine presents a complex picture. While research is exploring potential benefits in areas like weight management and cognitive function, these findings are preliminary and often overshadowed by established health warnings.

  • Weight Management: The reported appetite-suppressing effects of nicotine are met with strong expert caution, emphasizing that it is not a recommended or safe weight-loss strategy.

  • Cognitive Health: Ongoing scientific studies are investigating nicotine's potential positive impacts on memory and cognitive impairment, a field separate from its use as a recreational substance.

  • Risk Assessment: The long-term health implications of consuming nicotine through non-smoking methods, particularly for widespread use, remain largely unexamined and are a significant point of concern for health professionals.

  • Public Perception: The growing popularity of products like Zyn, coupled with anecdotal reports, may create a perception of nicotine as a wellness aid, which is not supported by broad medical consensus.
