With the rise of the supplement industry, a wide array of weight loss pills and products have emerged on the market. But with so many options, it can be hard to know which are safe and effective. Here’s an overview of some of the top proven weight loss pills.
How Weight Loss Pills Work
Weight loss pills typically work in one of three ways:
Appetite Suppressants
These decrease appetite and induce feelings of fullness, causing you to consume fewer calories. Examples include prescription pills like Phentermine and over-the-counter Hoodia or Glucomannan supplements.
Fat Blockers
These prevent the digestion and absorption of fat, allowing it to pass through the body unused. Alli is an FDA-approved fat blocker available over-the-counter.
Thermogenics
These increase thermogenesis, or fat burning, in the body. Many contain stimulants like caffeine, green tea extract, or capsaicin to achieve this.
However, no pill alone will make you lose weight. They are designed to complement, not replace diet and exercise efforts. For best results, sustainable lifestyle changes are still required.
Top Proven OTC Weight Loss Supplements
Here are some of the most popular and effective over-the-counter weight loss pills:
Glucomannan
Glucomannan is a water-soluble dietary fiber that comes from the konjac plant. Taking it before meals helps you feel full and eat less naturally. Studies show moderate weight loss.
Green Tea Extract
Green tea extract provides the active antioxidant EGCG that stimulates metabolism and fat burning. Look for standardized extracts to get effective dosing. Green tea also provides caffeine for energy.
Conjugated Linoleic Acid (CLA)
CLA is a naturally occurring fatty acid that aids fat loss and lean muscle growth. Research indicates doses of 3-6 grams per day can provide modest weight loss. CLA is very safe with minimal side effects.
Green Coffee Bean Extract
Unroasted coffee beans are rich in chlorogenic acid, a potent antioxidant that supports fat metabolism. Green coffee bean also contains natural caffeine to boost energy and suppress appetite.
Garcinia Cambogia
This fruit rind extract contains hydroxy citric acid (HCA) that may inhibit fat production and suppress appetite by regulating serotonin. Look for at least 50% HCA. Studies show mixed results.
Reed More Is Intermittent Fasting Effective for Weight Loss?
Raspberry Ketones
Raspberry ketones are natural phenolic compounds that create the distinctive smell of raspberries. Animal studies show they boost metabolic rate and fat burning, but limited evidence exists for humans.
As with any supplement, consult your doctor before taking especially if you have underlying health conditions or take medications. Purchase quality products from reputable companies.
Prescription Weight Loss Medications
For those with a BMI over 30 or obesity-related conditions, prescription weight loss drugs may be an option in addition to lifestyle modifications.
Phentermine
This stimulant suppresses appetite by altering neurotransmitter levels in the brain. It is fast-acting but usually taken short-term due to side effects. Phentermine works best paired with diet and exercise.
Orlistat (Xenical, Alli)
Orlistat blocks the absorption of dietary fat by binding to gastrointestinal lipase. This allows about 30% of fat to pass through the body undigested. Side effects include cramps, gas, and oily stools.
Contrave (bupropion/naltrexone)
Contrave combines antidepressant bupropion and opioid antagonist naltrexone to reduce appetite and food cravings. Common side effects include nausea and constipation.
Qsymia (phentermine/topiramate)
Qsymia combines phentermine with the seizure drug topiramate for appetite suppression. People with heart disease or glaucoma should avoid it due to the risk of dangerous side effects. Monitoring is required.
Saxenda (liraglutide)
Saxenda is an injected glucagon-like peptide-1 analog that regulates appetite by delaying gastric emptying. Nausea, diarrhea and gallbladder issues can occur. It also improves blood sugar control.
Discuss the risks and benefits of prescription options with your doctor to determine if one may be appropriate for your situation and health status. Never mix weight loss drugs or take them with additional supplements without medical guidance.
Effective Over-the-Counter Weight Loss Drug Alternatives
Several OTC supplements provide effects similar to prescription weight loss drugs more gently for those seeking more natural options:
Fiber supplements
Psyllium husk, glucomannan and other fibers add bulk and suppress appetite like Contrave. They also support regularity.
Apple cider vinegar
ACV mimics some fat-blocking effects of Orlistat through acetic acid. It also reduces appetite and aids digestion.
Green tea or green coffee extract
These naturally caffeinated extracts mimic fat fat-burning effects of stimulants like phentermine more mildly while providing antioxidant benefits.
Spicy cayenne supplements
Capsaicin in cayenne increases thermogenesis similar to Qsymia, supporting fat burn without stimulants.
Always start new supplements cautiously at lower doses and consult a medical professional if on medications or managing health conditions. High-quality matters for safety and results.
5 FAQs About Weight Loss Pills:
Are weight loss pills safe?
Over-the-counter supplements are generally safe for most healthy adults. Prescription drugs carry more risks and require medical oversight. Consult your doctor before taking any new medication or supplement.
How much weight can you lose by taking diet pills?
Most people lose just 5-10% of body weight on pills alone. Optimizing diet and adding daily exercise enhances results for 1-2 pound weekly loss. Do not expect dramatic weight loss from any pill.
Do you gain the weight back when you stop taking diet pills?
If underlying lifestyle habits don’t change, yes. Diet and exercise changes must be maintained after stopping pills to keep weight off. Use pills as a tool, not a cure.
What diet pills work?
The most proven OTC options are fiber supplements, green tea extract, green coffee bean extract and conjugated linoleic acid. Prescription medications work but have more side effects.
Are keto diet pills safe?
Some contain beta hydroxybutyrate (BHB) salts that can modestly induce ketosis. However, excessive doses can cause side effects like nausea. Safer options provide BHB through foods like exogenous ketones.
Conclusion
When combined with diet, exercise, and behavioral changes, weight loss pills can provide additional support for fat loss and weight control in the short term. However, a holistic lifestyle approach is necessary for sustained long-term results after discontinuing pills. Work with your doctor to find the safest options that fit your needs.
