Nicotine replacement therapy (NRT) is a common method used to aid individuals in quitting smoking. It involves the use of products that deliver controlled doses of nicotine without the harmful toxins found in cigarettes. These products aim to reduce nicotine cravings and alleviate withdrawal symptoms. While NRT is primarily designed for smoking cessation, some have considered using nicotine patches specifically for weight loss, based on the idea that nicotine can suppress appetite. This article explores the effectiveness of nicotine patches for weight loss, examining the evidence, potential risks, and alternative approaches.
Understanding Nicotine Replacement Therapy
Nicotine replacement therapy comes in various forms, including:
- Nicotine patch: A transdermal patch that delivers a steady dose of nicotine through the skin.
- Nicotine gum: A chewing gum that releases nicotine when chewed.
- Nicotine lozenges: Similar to gum, these dissolve in the mouth and release nicotine.
- Nicotine inhaler: A device that allows users to inhale nicotine vapor.
- Nasal spray: A spray that delivers nicotine quickly through the nasal passages.
All of these work equally well if they are used correctly. Before starting NRT, it's important to consider a few key points:
- The required nicotine dose may depend on the number of cigarettes smoked.
- Combining NRT with a counseling program can significantly improve the chances of quitting.
- Smoking while using NRT is dangerous and can lead to nicotine toxicity.
- NRT can help prevent weight gain during use, but weight gain may still occur after stopping.
- The nicotine dose should be gradually reduced over time.
Nicotine Patches: How They Work
Nicotine patches are available both over-the-counter and by prescription. A single patch is worn daily, replaced every 24 hours. The patch should be applied to a hairless area of the body above the waist and below the neck, rotating the application site daily. Some users experience odd dreams when wearing the patch at night and may prefer to remove it before sleeping. Individuals who smoke fewer than 10 cigarettes daily or weigh less than 99 pounds should start with a lower dose patch.
The Claim: Nicotine as an Appetite Suppressant
The idea that nicotine can aid in weight loss stems from its effects on the brain. Nicotine stimulates the release of dopamine and serotonin, neurotransmitters associated with pleasure and appetite suppression. This has led some to believe that nicotine patches could be a safe way to jump-start weight loss.

The Reality: Risks and Lack of Evidence
Despite the theoretical basis, there is no solid research to support the use of nicotine patches specifically for weight loss. Moreover, using nicotine comes with significant health risks, including:
- High blood pressure
- Narrowed and hardened arteries
- Addiction
- Changes in the brain
- Increased risk of coronary artery disease, hypertension, heart attack, and stroke
- Anxiety, irritability, insomnia, and mouth sores
Kecia Christensen, APRN-NP, emphasizes that nicotine is highly addictive and can alter brain function. Every time nicotine is used, the brain produces more nicotine receptors, leading to addiction. The release of dopamine associated with nicotine use can also overshadow healthier ways of achieving dopamine release, such as exercise and meditation.
Scientific Studies on Nicotine and Weight
Research on nicotine and weight is mixed. Some studies on rats have shown that self-administered nicotine can suppress weight gain and reduce body fat without altering lean mass. These studies indicated that nicotine increased fat utilization. However, these findings are from animal studies and may not directly translate to humans.
Human studies present a more complex picture. While smokers tend to weigh less than non-smokers, the weight-suppressive effects of smoking are not solely attributed to reduced food intake. Some studies suggest that nicotine may increase energy expenditure, but results are inconsistent.
A study published in Psychopharmacology (2018) found that nicotine self-administration in rats led to weight suppression, suggesting an impact on energy expenditure. Another study in Eat Behav (2013) examined the effects of nicotine patches on postmenopausal women trying to quit smoking. The results indicated that nicotine patch use actually increased caloric intake during treatment and did not prevent post-cessation weight gain.

Nicotine Pouches: A Dangerous Trend
The use of nicotine pouches, such as Zyn or Velo, has recently gained popularity as a weight loss aid, often referred to as "gas station Ozempic®." However, these products carry similar risks to other nicotine products and are not FDA-regulated, meaning their nicotine content and additives are uncertain.
Christensen warns that nicotine pouches are not a harmless alternative to smoking cessation products. They can lead to addiction and have the same vasoconstrictive effects as other nicotine products, increasing the risk of cardiovascular problems.
Nicotine Replacement Therapy and Post-Cessation Weight Gain
Post-cessation weight gain is a common concern for individuals quitting smoking. While nicotine replacement therapy has been suggested as a way to limit this weight gain, the evidence is not conclusive.
A study involving postmenopausal women found that those using nicotine patches increased their caloric intake compared to those on a placebo patch. However, there were no significant differences in weight or BMI between the groups. This suggests that while nicotine may influence energy intake, it does not necessarily prevent weight gain.
Another study indicated that compliance with nicotine gum dosing instructions was associated with less weight gain, suggesting that the pharmacological effects of nicotine may play a role. The delivery method of nicotine replacement therapy may also be a factor, with oral forms like gum and lozenges potentially acting as substitutes for snacking.

The Importance of FDA-Regulated Products
It's crucial to differentiate between FDA-regulated nicotine replacement products (lozenges, gum, patches, nasal sprays) and unregulated nicotine pouches. The regulated products undergo scrutiny to ensure safety and accurate nicotine content, whereas the pouches do not.
Nicotine's Impact on Energy Balance
The impact of nicotine on energy balance has been extensively studied in rodents, often using experimenter-administered nicotine. These studies have shown reduced food intake, increased physical activity, increased thermogenesis, and increased basal metabolism. However, the doses used in these studies are often higher than what animals would self-administer, and the effects of experimenter-administered versus self-administered nicotine can differ.
Studies involving self-administered nicotine in rats have shown that it can suppress body weight independent of food intake, suggesting that nicotine's impact on body weight suppression results primarily from increased energy expenditure.
Alternative Approaches to Weight Loss
Given the risks associated with nicotine, safer and more effective weight loss strategies are recommended. Kecia Christensen advocates for a balanced approach based on "calories in and calories burned." This involves:
- Determining daily caloric needs
- Creating a 500-calorie daily deficit through diet and exercise
- Consuming a balanced diet with protein at every meal
- Avoiding sugar and practicing portion control
- Choosing healthy carbohydrates like vegetables and whole grains
Exercise is also crucial for both weight loss and dopamine release. Simple activities like drinking water, deep breathing, meditation, and hugging can also release dopamine, providing healthier alternatives to nicotine.
