Ending Smoking.


Cigarette smoking is responsible for more than 480,000 deaths per year

How to quit smoking?

Why is quitting so hard?

We all know the health risks of smoking, but that doesn’t make it any easier to kick the habit. Whether you’re an occasional teen smoker or a lifetime pack-a-day smoker, quitting can be really tough.

Smoking tobacco is both a physical addiction and a psychological habit. The nicotine from cigarettes provides a temporary—and addictive—high. Eliminating that regular fix of nicotine causes your body to experience physical withdrawal symptoms and cravings. Because of nicotine’s “feel good” effect on the brain, you may turn to cigarettes as a quick and reliable way to boost your outlook, relieve stress, and unwind. Smoking can also be a way of coping with depression, anxiety, or even boredom. Quitting means finding different, healthier ways to cope with those feelings.

Smoking is also ingrained as a daily ritual. It may be an automatic response for you to smoke a cigarette with your morning coffee, while taking a break at work or school, or on your commute home at the end of a hectic day. Or maybe your friends, family, or colleagues smoke, and it’s become part of the way you relate with them.

To successfully stop smoking, you’ll need to address both the addiction and the habits and routines that go along with it. But it can be done. With the right support and quit plan, any smoker can kick the addiction—even if you’ve tried and failed multiple times before.

Your personal stop smoking plan

While some smokers successfully quit by going cold turkey, most people do better with a tailored plan to keep themselves on track. A good quit plan addresses both the short-term challenge of stopping smoking and the long-term challenge of preventing relapse. It should also be tailored to your specific needs and smoking habits.

Questions to ask yourself

Take the time to think of what kind of smoker you are, which moments of your life call for a cigarette, and why. This will help you to identify which tips, techniques, or therapies may be most beneficial for you.

Are you a very heavy smoker (more than a pack a day)? Or are you more of a social smoker? Would a simple nicotine patch do the job?

Are there certain activities, places, or people you associate with smoking? Do you feel the need to smoke after every meal or whenever you break for coffee?

Do you reach for cigarettes when you’re feeling stressed or down? Or is your cigarette smoking linked to other addictions, such as alcohol or gambling?

Start your stop smoking plan with START

S = Set a quit date.

Choose a date within the next two weeks, so you have enough time to prepare without losing your motivation to quit. If you mainly smoke at work, quit on the weekend, so you have a few days to adjust to the change.

T = Tell family, friends, and co-workers that you plan to quit.

Let your friends and family in on your plan to quit smoking and tell them you need their support and encouragement to stop. Look for a quit buddy who wants to stop smoking as well. You can help each other get through the rough times.

A = Anticipate and plan for the challenges you’ll face while quitting.

Most people who begin smoking again do so within the first three months. You can help yourself make it through by preparing ahead for common challenges, such as nicotine withdrawal and cigarette cravings.

R = Remove cigarettes and other tobacco products from your home, car, and work.

Throw away all of your cigarettes, lighters, ashtrays, and matches. Wash your clothes and freshen up anything that smells like smoke. Shampoo your car, clean your drapes and carpet, and steam your furniture.

T = Talk to your doctor about getting help to quit.

Your doctor can prescribe medication to help with withdrawal symptoms. If you can’t see a doctor, you can get many products over the counter at your local pharmacy, including nicotine patches, lozenges, and gum.

Identify your smoking triggers

One of the best things you can do to help yourself quit is to identify the things that make you want to smoke, including specific situations, activities, feelings, and people.

Keep a craving journal

A craving journal can help you zero in on your patterns and triggers. For a week or so leading up to your quit date, keep a log of your smoking. Note the moments in each day when you crave a cigarette:

  1. What time was it?
  2. How intense was the craving (on a scale of 1-10)?
  3. What were you doing?
  4. Who were you with?
  5. How were you feeling?
  6. How did you feel after smoking?

Do you smoke to relieve unpleasant feelings?

Many of us smoke to manage unpleasant feelings such as stress, depression, loneliness, and anxiety. When you have a bad day, it can seem like cigarettes are your only friend. As much comfort as cigarettes provide, though, it’s important to remember that there are healthier and more effective ways to keep unpleasant feelings in check. These may include exercising, meditating, relaxation strategies, or simple breathing exercises.

For many people, an important aspect of giving up smoking is to find alternate ways to handle these difficult feelings without turning to cigarettes. Even when cigarettes are no longer a part of your life, the painful and unpleasant feelings that may have prompted you to smoke in the past will still remain. So it’s worth spending some time thinking about the different ways you intend to deal with stressful situations and the daily irritations that would normally have you lighting up.

Tips for avoiding common triggers

Alcohol. Many people smoke when they drink. Try switching to non-alcoholic drinks or drink only in places where smoking inside is prohibited. Alternatively, try snacking on nuts, chewing on a cocktail stick or sucking on a straw.

Other smokers. When friends, family, and co-workers smoke around you, it can be doubly difficult to give up or avoid relapse. Talk about your decision to quit so people know they won’t be able to smoke when you’re in the car with them or taking a coffee break together. In your workplace, find non-smokers to have your breaks with or find other things to do, such as taking a walk.

End of a meal. For some smokers, ending a meal means lighting up, and the prospect of giving that up may appear daunting. However, you can try replacing that moment after a meal with something else, such as a piece of fruit, a healthy dessert, a square of chocolate, or a stick of gum.

Coping with nicotine withdrawal symptoms

Once you stop smoking, you’ll likely experience a number of physical symptoms as your body withdraws from nicotine. Nicotine withdrawal begins quickly, usually starting within an hour of the last cigarette and peaking two to three days later. Withdrawal symptoms can last for a few days to several weeks and differ from person to person.

Common nicotine withdrawal symptoms include:

  1. Cigarette cravings
  2. Irritability, frustration, or anger
  3. Anxiety or nervousness
  4. Difficulty concentrating
  5. Restlessness
  6. Increased appetite
  7. Headaches
  1. Insomnia
  2. Tremors
  3. Increased coughing
  4. Fatigue
  5. Constipation or upset stomach
  6. Depression
  7. Decreased heart rate

As unpleasant as these withdrawal symptoms may be, it’s important to remember that they are only temporary. They will get better in a few weeks as the toxins are flushed from your body. In the meantime, let your friends and family know that you won’t be your usual self and ask for their understanding.

Manage cigarette cravings

While avoiding smoking triggers will help reduce your urge to smoke, you probably can’t avoid cigarette cravings entirely. Fortunately, cravings don’t last long—typically, about 5 or 10 minutes. If you’re tempted to light up, remind yourself that the craving will soon pass and try to wait it out. It helps to be prepared in advance by having strategies to cope with cravings.

Distract yourself. Do the dishes, turn on the TV, take a shower, or call a friend. The activity doesn’t matter as long as it gets your mind off smoking.

Remind yourself why you quit. Focus on your reasons for quitting, including the health benefits (lowering your risk for heart disease and lung cancer, for example), improved appearance, money you’re saving, and enhanced self-esteem.

Get out of a tempting situation. Where you are or what you’re doing may be triggering the craving. If so, a change of scenery can make all the difference.

Reward yourself. Reinforce your victories. Whenever you triumph over a craving, give yourself a reward to keep yourself motivated.

Coping with cigarette cravings in the moment

Find an oral substitute – Keep other things around to pop in your mouth when cravings hit. Try mints, carrot or celery sticks, gum, or sunflower seeds. Or suck on a drinking straw.

Keep your mind busy – Read a book or magazine, listen to some music you love, do a crossword or Sudoku puzzle, or play an online game.

Keep your hands busy – Squeeze balls, pencils, or paper clips are good substitutes to satisfy that need for tactile stimulation.

Brush your teeth – The just-brushed, clean feeling can help banish cigarette cravings.

Drink water – Slowly drink a large glass of water. Not only will it help the craving pass, but staying hydrated helps minimize the symptoms of nicotine withdrawal.

Light something else – Instead of lighting a cigarette, light a candle or some incense.

Get active – Go for a walk, do some jumping jacks or pushups, try some yoga stretches, or run around the block.

Try to relax – Do something that calms you down, such as taking a warm bath, meditating, reading a book, or practicing deep breathing exercises.

Go somewhere smoking is not permitted – Step into a public building, store, mall, coffee shop, or movie theatre, for example.

Preventing weight gain after you stop smoking

Smoking acts as an appetite suppressant, so gaining weight is a common concern for many of us when we decide to give up cigarettes. You may even be using it as a reason not to quit. While it’s true that many smokers put on weight within six months of stopping smoking, the gain is usually small—about five pounds on average—and that initial gain decreases over time. It’s also important to remember that carrying a few extra pounds for a few months won’t hurt your heart as much as smoking does. However, gaining weight is NOT inevitable when you stop smoking.

Smoking dampens your sense of smell and taste, so after you quit food will often seem more appealing. You may also gain weight if you replace the oral gratification of smoking with eating unhealthy comfort foods. Therefore, it’s important to find other, healthy ways to deal with unpleasant feelings such as stress, anxiety, or boredom rather than mindless, emotional eating.

Nurture yourself. Instead of turning to cigarettes or food when you feel stressed, anxious, or depressed, learn new ways to quickly soothe yourself. Listen to uplifting music, play with a pet, or sip a cup of hot tea, for example.

Eat healthy, varied meals. Eat plenty of fruit, vegetables, and healthy fats. Avoid sugary food, sodas, fried, and convenience food.

Learn to eat mindfully. Emotional eating tends to be automatic and virtually mindless. It’s easy to polish off a tub of ice cream while zoning out in front of the TV or staring at your phone. But by removing distractions when you eat, it’s easier to focus on how much you’re eating and tune into your body and how you’re really feeling. Are you really still hungry or eating for another reason?

Drink lots of water. Drinking at least six to eight 8 oz. glasses will help you feel full and keep you from eating when you’re not hungry. Water will also help flush toxins from your body.

Take a walk. Not only will it help you burn calories and keep the weight off, but it will also help alleviate feelings of stress and frustration that accompany smoking withdrawal.

Snack on guilt-free foods. Good choices include sugar-free gum, carrot and celery sticks, or sliced bell peppers or jicama.

Medication and therapy to help you quit

There are many different methods that have successfully helped people to kick the smoking habit. While you may be successful with the first method you try, more likely you’ll have to try a number of different methods or a combination of treatments to find the ones that work best for you.

Medications

Smoking cessation medications can ease withdrawal symptoms and reduce cravings. They are most effective when used as part of a comprehensive stop smoking program monitored by your physician. Talk to your doctor about your options and whether an anti-smoking medication is right for you. The U.S. Food and Drug Administration (FDA) approved options are:

Nicotine replacement therapy. Nicotine replacement therapy involves “replacing” cigarettes with other nicotine substitutes, such as nicotine gum, patch, lozenge, inhaler, or nasal spray. It relieves some of the withdrawal symptoms by delivering small and steady doses of nicotine into your body without the tars and poisonous gases found in cigarettes. This type of treatment helps you focus on breaking your psychological addiction and makes it easier to concentrate on learning new behaviors and coping skills.

Non-nicotine medication. These medications help you stop smoking by reducing cravings and withdrawal symptoms without the use of nicotine. Medications such as bupropion (Zyban) and varenicline (Chantix, Champix) are intended for short-term use only.

What you need to know about e-cigarettes (vaping)

While some people find that vaping can help them to stop smoking, the FDA has not approved vaping as a method of smoking cessation. And recent news reports have even linked vaping to severe lung disease, prompting many questions about the safety of vaping. Here’s what you need to know:

  • In the United States, the FDA does not regulate e-cigarette products.
  • The FDA warns that vaping is “not safe for youth, young adults, pregnant women, or adults who do not currently use tobacco products.”
  • It’s hard to always know exactly what’s in e-cigarettes.
  • The liquid used in some e-cigarettes contains nicotine, which has many negative health effects. It can lead to high blood pressure and diabetes and can be especially dangerous to the developing brains of children and teens.
  • There is no information available about the long-term effects vaping can have on your health.
  • Until more is known, federal and state authorities recommend avoiding all vaping.

Alternative therapies

There are several things you can do to stop smoking that don’t involve nicotine replacement therapy, vaping, or prescription medications. These include:

Hypnosis – This is a popular option that has produced good results for many smokers struggling to quit. Forget anything you may have seen from stage hypnotists, hypnosis works by getting you into a deeply relaxed state where you are open to suggestions that strengthen your resolve to stop smoking and increase your negative feelings toward cigarettes.

Acupuncture – One of the oldest known medical techniques, acupuncture is believed to work by triggering the release of endorphins (natural pain relievers) that allow the body to relax. As a smoking cessation aid, acupuncture can be helpful in managing smoking withdrawal symptoms.

Behavioral Therapy – Nicotine addiction is related to the habitual behaviors or rituals involved in smoking. Behavior therapy focuses on learning new coping skills and breaking those habits.

Motivational Therapies – Self-help books and websites can provide a number of ways to motivate yourself to give up smoking. One well known example is calculating the monetary savings. Some people have been able to find the motivation to quit just by calculating how much money they will save. It may be enough to pay for a summer vacation.

Smokeless or spit tobacco is NOT a healthy alternative to smoking

Smokeless tobacco, otherwise known as spit or chewing tobacco, is not a safe alternative to smoking cigarettes. It contains the same addictive chemical, nicotine, contained in cigarettes. In fact, the amount of nicotine absorbed from smokeless tobacco can be 3 to 4 times the amount delivered by a cigarette.

What to do if you slip or relapse

Most people try to stop smoking several times before they kick the habit for good, so don’t beat yourself up if you slip up and smoke a cigarette. Instead, turn the relapse into a rebound by learning from your mistake. Analyze what happened right before you started smoking again, identify the triggers or trouble spots you ran into, and make a new stop-smoking plan that eliminates them.

It’s also important to emphasize the difference between a slip and a relapse. If you start smoking again, it doesn’t mean that you can’t get back on the wagon. You can choose to learn from the slip and let it motivate you to try harder or you can use it as an excuse to go back to your smoking habit. But the choice is yours. A slip doesn’t have to turn into a full-blown relapse.

You’re not a failure if you slip up. It doesn’t mean you can’t quit for good.

Don’t let a slip become a mudslide. Throw out the rest of the pack. It’s important to get back on the non-smoking track as soon as possible.

Look back at your quit log and feel good about the time you went without smoking.

Find the trigger. Exactly what was it that made you smoke again? Decide how you will cope with that issue the next time it comes up.

Learn from your experience. What has been most helpful? What didn’t work?

Are you using a medicine to help you quit? Call your doctor if you start smoking again. Some medicines cannot be used if you’re smoking at the same time.

Helping a loved one to stop smoking

It’s important to remember that you cannot make a friend or loved one give up cigarettes; the decision has to be theirs. But if they do make the decision to stop smoking, you can offer support and encouragement and try to ease the stress of quitting. Investigate the different treatment options available and talk them through with the smoker; just be careful never to preach or judge. You can also help a smoker overcome cravings by pursuing other activities with them, and by keeping smoking substitutes, such as gum, on hand.

If a loved one slips or relapses, don’t make them feel guilty. Congratulate them on the time they went without cigarettes and encourage them to try again. Your support can make all the difference in helping your loved one eventually kick the habit for good.

Helping a teen to quit

Most smokers try their first cigarette around the age of 11, and many are addicted by the time they turn 14. The use of e-cigarettes (vaping) has also soared dramatically in recent years. While the health implications of vaping aren’t yet fully known, the FDA warns that it’s not safe for teens and we do know that teens who vape are more likely to begin smoking cigarettes. This can be worrying for parents, but it’s important to appreciate the unique challenges and peer pressure teens face when it comes to quitting smoking (or vaping). While the decision to give up has to come from the teen smoker him- or herself, there are still plenty of ways for you to help.

Tips for parents of teens who smoke or vape

  • Find out why your teen is smoking or vaping; they may want to be accepted by their peers or be seeking attention from you. Rather than making threats or ultimatums, talk about what changes can be made in their life to help them stop smoking.
  • If your child agrees to quit, be patient and supportive as they go through the process.
  • Set a good example by not smoking yourself. Parents who smoke are more likely to have kids who smoke.
  • Know if your kids have friends that smoke or vape. Talk with them about how to refuse a cigarette or e-cigarette.
  • Explain the health dangers and the unpleasant side effects smoking can have on their appearance (such as bad breath, discolored teeth and nails).
  • Establish a smoke-free policy in your home. Don’t allow anyone to smoke or vape indoors at any time.

Smoking, A hazard!

Why should I quit smoking?

The decision to quit smoking is the most important step you can take to improve your overall health. It is NEVER too late to quit. By quitting smoking, you can:

  • Lengthen your life expectancy
  • Decrease your risk of disease (including lung cancer, throat cancer, emphysema, heart disease, high blood pressure, ulcers and reflux, erectile and sexual dysfunction, kidney disease, and other conditions)
  • Reduce your risk of respiratory and anesthesia complications during surgery and risk of infection or re-admission after an operation
  • Decrease the chance that your children will become sick (respiratory and ear infections are much more common among children exposed to secondhand smoke)
  • Feel healthier (after quitting, you won’t cough as much, have as many sore throats or stuffy noses, and will have an increased energy level and exercise tolerance)
  • Improve your sense of taste and smell
  • Improve your personal life (smoking causes erectile dysfunction and overall sexual dysfunction)
  • Improve your looks (smoking cause wrinkles, stained teeth, and dull skin)
  • Save money – a 1 pack-per-day habit costs $2,200/year

What’s the best way to quit smoking?

There is no best way to quit smoking. Everyone has different smoking patterns, habits, levels of addiction, and preferences. What works best for one person may have little impact on someone else. For this reason, the best smoking cessation programs offer several proven methods, not just one.

The Cleveland Clinic Tobacco Treatment Center offers a variety of methods to help people who want to become nonsmokers. Our program offers:

  • An individualized treatment plan. A certified tobacco specialist determines how dependent you are on nicotine, how ready you are to quit, and your preferred method of learning. The specialist will develop a treatment plan specifically designed for you to give you the best chance of quitting successfully.
  • Use of a combination of medications and behavioral therapy. Your treatment plan includes the latest tobacco treatment medications such as bupropion, varenicline, and/or nicotine replacement therapies (e.g., nicotine gum or the patch). Behavior therapies include exercise, reading material, and individual or group counseling.
  • Follow-up. The tobacco treatment specialist follows up on your progress, offers tips and celebrates your successes. Cleveland Clinic Tobacco Cessation specialists developed the PQRS strategy to help you quit:
    • PREPARE: You need a little time before you quit –14 to 30 days is usually optimal – to prime your mind and body for success.
    • QUIT: Anti-craving drugs and/or nicotine replacement therapy will lessen your urge to smoke. Resources are available to help you on your journey to a tobacco-free life.
    • RELAPSE PREVENTION: Develop the ability to identify situations that may cause you to slip and learn new skills to prevent relapse.
    • STRESS MANAGEMENT: Find alternatives to reaching for tobacco to cope with stress. Tobacco actually INCREASES the stress on your body – it increases heart rate, blood pressure, and constricts blood vessels, making your heart, kidneys, and other vital organs work harder.

What’s the next step?

Being ready and wanting to quit is the most important part. You need to decide to give yourself the most precious gift a smoker can give to him or herself – a gift of life, health, and self-esteem – by becoming a nonsmoker. Treatment costs less than a pack of cigarettes a day, and varies based on the personalized plan developed for each individual and his or her ability to pay.

Do any weight loss pills really work?

When it comes to weight loss, there is no shortage of pills, drinks, and supplements claiming to help the weight fall off. But do weight loss pills help, and are they safe?

The best weight loss pills may contain one or more active ingredients intended to increase fat burning, decrease appetite, or reduce absorption of fat.

Not all weight loss pills and supplements are created equal. Certain pills may cause unpleasant side effects while others may not be proven to result in weight loss.

We will look at the following nine weight loss pills and supplements:

  • Alli (orlistat)
  • caffeine
  • glucomannan
  • garcinia cambogia extract
  • pyruvate
  • green tea extract
  • conjugated linoleic acid
  • Hydroxycut
  • prescription weight loss pills

1. Alli (orlistat)

Weight loss and diet pills surrounded by measuring tape.
It is important to research carefully before choosing a weight loss pill, as some may have side effects, or interact with existing conditions.

Alli is the brand name for the drug orlistat. It is one of the most popular weight loss pills.

Orlistat is available as a prescription drug and also sold over the counter. It works by preventing the body from breaking down of some of the fat that people eat. When the intestines absorb less fat, weight loss may occur.

A review of 11 studies indicated that orlistat might increase weight loss by a small amount. The review found that those who took orlistat lost an average of 2.9 percent more weight than those who did not take the drug.

Orlistat may cause a change in bowel habits. People taking orlistat may experience side effects, such as diarrhea, stomach pain, and difficulty controlling bowel movements.

2. Caffeine

Caffeine is a stimulant found in coffee, tea, soft drinks, and chocolate. It is also often added to diet pills and supplements.

According to a study of 76 obese adults, people who had high caffeine intake saw a greater reduction in fat mass, weight circumference, and overall weight compared to those who had low caffeine intake.

Side effects of caffeine include jitteriness, increased heart rate, and trouble sleeping.

3. Glucomannan

Glucomannan is a type of fiber supplement. It works by absorbing water in the gut, leading to a feeling of fullness that may prompt people to eat less.

Studies appear to be conflicting on whether glucomannan can aid in weight loss, however.

A 2005 studyTrusted Source of 176 people indicated that glucomannan contributed to weight loss in healthy, overweight adults.

However, a more recent review of randomized control trials indicated that glucomannan did not appear to result in significant weight loss.

For those who do take glucomannan, side effects may include gas, diarrhea, and stomach pain.

4. Garcinia cambogia extract

Garcinia cambogia.
Garcinia cambogia extract is a popular natural weight loss aid.

Garcinia cambogia is a fruit that contains hydroxycitric acid, which is thought to help weight loss.

Garcinia cambogia extract contains the juices from this small fruit and is available as a weight loss pill. Garcinia cambogia may inhibit or prevent a fat-producing enzyme called citric acid lyase.

There is little scientific evidence to support the use of this extract to help with weight loss. According to one reportTrusted Source, the effectiveness of the extract in long-term clinical trials and large-scale studies has not been proven.

Although garcinia cambogia extract may not aid in weight loss, it does not appear to cause many side effects when taken in reasonable doses. The report above also indicated that adverse effects did not occur with a dietary dosage of up to 2,800 milligrams (mg) per day.

5. Pyruvate

The body produces pyruvate when it breaks down sugar. Pyruvate is also sold as a supplement to assist with weight loss by helping break down fat and boosting metabolism.

According to the National Institute of Health’s Office of Dietary Supplements, pyruvate may have some effects on weight loss. Existing studies are weak, so results are not conclusive.

Side effects of pyruvate include gas and bloating.

6. Green tea extract

Many diet pills contain green tea because it may increase the body’s ability to burn fat, and especially fat in the stomach area.

Although more evidence is needed, some research indicates that drinks containing green tea extract may promote the loss of fat around the stomach area. The increase in fat loss may also result in modest weight loss.

Although green tea extract is usually well tolerated, it can cause stomach pain, constipation, and nausea.

7. Conjugated linoleic acid

Conjugated linoleic acid is a type of fatty acid found mostly in beef and dairy. It has been marketed as one of the best weight loss pills for its potential to boost metabolism and decrease appetite.

However, the majority of the studies on conjugated linoleic acid leading to weight loss have been carried out on animals. According to a review of research, weight loss appears to be minimal in human studies.

Conjugated linoleic acid appears to be safe in doses of up to 6 grams per day for up to 12 months. Possible side effects include stomach discomfort, diarrhea, or constipation. It may not be suitable for people who have diabetes.

8. Hydroxycut

Weight loss and diet protein powder and supplements.
Hydroxycut comes in different forms, and is considered a supplement.

Hydroxycut is a popular dietary supplement. There are different Hydroxycut products, which contain various ingredients. Hydroxycut products typically contain plant extracts and caffeine, although caffeine-free versions of the supplement are also available.

There are no studies that review Hydroxycut specifically. Caffeine, which has been studied, may contribute to small amounts of weight loss.

Since the ingredients of Hydroxycut vary, it is difficult to state the possible side effects. Hydroxycut supplements that contain caffeine may cause nervousness and increased heart rate.

Hydroxycut is considered a supplement and does not go through the same rigorous testing as drugs to determine its safety.

9. Prescription weight loss pills

Certain weight loss pills are only available through a doctor’s prescription. Although there are various pills on the market, most weight loss medications work by making it harder to absorb dietary fat or by suppressing the appetite.

Two common weight loss pills are Belviq and Qsymia.

Prescription pills may lead to some weight loss, but they can have side effects. Depending on the prescription, side effects of weight loss pills can include stomach pain, dry mouth, and diarrhea.

Takeaway

When it comes to the best weight loss pills, it appears there is no magic bullet. Although some of the diet pills and supplements mentioned above may contribute to weight loss, the amounts are usually modest.

Caffeine, green tea extract, and orlistat appear to have the most research to back up their claims.

Some weight loss pills can also lead to side effects, with the most common being stomach discomfort and changes in bowel movements.

Dietary supplements do not face the same scrutiny as drugs that are approved by the United States Food and Drug Administration (FDA), so their safety is not always fully understood. Before taking any supplement for weight loss, it is best to talk with a doctor or other healthcare professional.

The best bet for people trying to lose weight is to reduce portion size, eat lean protein and veggies, and get regular exercise.
