Weight Loss Pills – Overview

Weight-loss pills, be they prescription or over-the-counter, use a variety of mechanisms for burning fat and losing weight. Some diet pills, to speed up metabolism use certain ingredients, like caffeine. This initiates the fat-burning process of thermogenesis.

Other diet pills suppress hunger, so you don’t overeat, or so you don’t crave carbohydrates. There are pills specifically geared towards those who are following a keto diet. They include extra ketones, which keep the body in a fat-burning state.

Even with some of the best weight loss supplements and best diet pills readily found online or within stores, it can be difficult to choose the appropriate one. Confusion arises with the questions like What are the best diet pills for women? What supplements help with weight loss? Which weight loss supplements actually work? What are the best natural weight loss supplements?

No weight loss pills work to result in ‘miraculous’ weight loss. A good diet and exercise will always be part of the equation, but there are some diet pills that are known to be better than others, so it’s important to look at all of the factors when choosing the best one for you.

“Whether in pill, powder or liquid form, the goal of dietary supplements is often the same: to supplement your diet to get enough nutrients and enhance health”, explains Jeffrey Millstein, MD, physician at Penn Internal Medicine Woodbury Heights.

What are our Ideal Ingredients for Choosing The Best Weight Loss Supplements?

  • Garcinia Cambogia ExtractWeight Loss Supplements with Garcinia Cambogia has a lot of hydroxycitric acid, which can speed up the metabolism and also curb hunger. There’s only minimal research showing[8] that this substance helps with weight loss.
  • Caffeine – It speeds up the metabolism and so it leads to a lot of fat burning. It also gives you extra energy, which helps you be more active. The Mayoclinic says that the amount of weight you can lose from caffeine is limited.
  • Green Coffee Bean Extract – This has a substance called chlorogenic acid, which burns fat. It also has other health benefits.[9]
  • Glucomannan – This is a dietary fiber is often used in foods because it’s an emulsifier. It has been sold as a weight-loss substance for 10 years, although there’s very little evidence to prove this[10].
  • Green Tea Extract – It initiates the process of thermogenesis, which does lead to weight loss[11]. It has quite a bit of caffeine, which quickens the metabolism.
  • Conjugated Linoleic Acid (CLA) – A collection of chemicals that make up the fatty acid linoleic acid. Research[12] indicated that ingesting CLA does lead to a moderate weight and fat loss.
  • Forskolin – It’s a weight-loss substance that many people think can release fatty acids, burning fat and making weight-loss more rapid. It may also prevent new fat from forming quickly on the body. The evidence[13] that Forskolin is an effective weight loss substance is not very strong.

How Do We Rank the ‘Best Weight Loss Pills’?

In order to rank each weight loss pill, we use a rigorous process where we research every element of both company and pill. We look at the reputation of the company, and how reliable and effective their products are in general.

We also look at their certifications in the industry, which is another indicator of how reputable the company is.

The ingredients are a key factor in deciding what the best diet pills are. We look at the scientific research behind each substance, and whether data backs up its weight-loss potential. Naturally, we also look carefully at customer reviews.

Here are the weight loss pills that really work –

  • The pills speed up the metabolism[2], which leads to weight loss.
  • According to the scientific research[3], these weight loss ingredients also have other healthy properties.
  • Many of them are rich in anti-oxidants.
“Supplements are meant to be supplementary — meaning they enhance benefits already provided by eating a well-rounded diet,” explains Dr. Jeffrey Millstein.

Side Effects of Diet Pills

According to the National Institute of Health[4], prescription weight loss medications can lead to different side effects depending on the specific pill.

These range from mild effects like diarrhea and stomach pain to more severe consequences like liver problems in rare cases.

Research on Conjugated Linoleic Acid has indicated that it does lead to weight loss, but that there are mild to moderate potential side effects[5] associated with its consumption. These include oxidative stress, insulin resistance, gastrointestinal irritation.

Green Coffee and Tea are high in caffeine, which can make you jittery or nervous and give you a lot of extra energy.

Some people are intolerant of ingesting caffeine. Caffeine is also a diuretic[6] which will send you running to the bathroom a few more times than usual. However, this has no negative effects.

One research study[7] reported mild side effects associated with taking Forskolin which included stomach upset and diarrhea.

“Like all dietary supplements, weight-loss supplements can have side effects and might interact with prescription and over-the-counter medications. In some cases, the active constituents of botanical or other ingredients promoted for weight loss are unknown or uncharacterized. Furthermore, many weight-loss supplements contain multiple ingredients that have not been adequately tested in combination with one another”, says National Institutes of Health.

Best Weight Loss Pills and Supplements FAQs

Do weight loss pills really work?

There are two types of diet pills – prescription, and over-the-counter supplements. There are some in each category that has some degree of effectiveness, depending on the quality and ingredients.

According to the Mayo Clinic, “All prescription weight-loss drugs approved for long-term use produce significant weight loss compared with placebo.” Supplements have anecdotal reports of effectiveness.

However, weight-loss pills are not a magic solution. The focus of weight loss should always be changing your eating habits and exercising. Pills are only a tool to speed up or enhance the effects of regular weight loss.

What should you look for when buying diet pills?

It’s really important to do your research when choosing a diet pill. There are a number of factors to consider. You want the best quality ingredients available, so check the back of the bottle against the list we’ve provided you.

In addition, do your own independent research on the ingredients and on the reliability of the manufacturer.

If you’re looking for the non-prescribed, best all natural diet pills, then you need to check that the ingredients really are all-natural. Have a look at the inactive ingredients to see that there aren’t any chemicals, dyes, or artificial flavors. The more organic, the better.

Naturally, the price is a concern, but you should also have a good look at the company’s money-back guarantee. Choose a product with at least 60 days. A 30-day guarantee isn’t long enough for you to try out the pills, see if they work, and send the product back before the end of the period to get your refund.

For any diet pill you’re considering, look at the warnings to see if there are any safety concerns. There may be concerns listed for people with specific issues or illnesses or just general safety concerns. Another way to find out about safety issues is to research the product to see what’s been said about it.

Finally, look into the scientific research both about the products that interest you – if there is any – and about the ingredients included. It’s important that you be aware of exactly what you’re putting in your body.

Who should buy weight loss pills?

Weight-loss pills are intended specifically for people who have weight-related health issues. It’s also for individuals who are at risk of having health problems due to overweight or obesity.

Someone is defined as overweight if they have a BMI (Body Mass Index) of more than 25. Obese is defined as having a BMI of over 30.

This is a decision that you must discuss with your doctor before beginning a regimen of diet pills. The physician will consider your medical history, the medications you are currently taking, and the benefits of weight loss to your overall health and lifestyle.

Not every person who is overweight or obese should be taking diet pills. Your doctor may decide that a special diet or other lifestyle change is more appropriate for you, or that you may succeed better at.

What is the best over the counter diet pill to get rid of belly fat?

There are no healthy over the counter weight loss pill that will get rid of body fat. Green tea extract contains an anti-oxidant called EGCG[14] which may help increase fat utilization, although you should not expect any miraculous results from this.

Which weight loss pills are safe?

There’s no guarantee on the safety of any these diet pills, including those which are prescription. This is because medications behave differently depending on the individual.

Both prescription and over-the-counter supplements have the potential for side effects or allergic reactions. This is yet another reason to consult with your physician before taking weight-loss pills.

What type of Weight Loss Supplements and Diet Pills

Checking our “best weight loss supplements” product reviews. Another way is to know what they should offer or what ingredients they should avoid. However, in order to make rather more important choices, you should first research about the categories of over-the-counter diet pills and supplements:

  • Appetite Suppressants
  • Fat Blockers
  • Carb Blockers
  • Thermogenic Fat Burners

Q: Can children or teenagers take weight-loss pills?

A: Weight-loss pills are not intended for children or teenagers. Most prescription diet pills are approved for adult use only, and this is also true of over-the-counter diet supplements.

Q: Is golow a good diet pill? Because after all of that I am confused as to what is the best weight loss supplement or diet pill.
A: Weight loss supplements and diet pills should always be chosen on the basis that if it is medically reviewed, or if the ingredients science backed.
Here, the list of Weight Loss Supplements & Diet Pills that we have provided on our page are reviewed by the experts and claims to work and give the best results.

Conclusion – What Else You Should Know

The bottom line is without proper diet and exercise none of these diet pills work. The bottles make a variety of claims, but they will not result in miraculous weight loss. We reviewed the most popular diet pills out there for the year and some information about each one.

Hopefully, this will help you decide both if a diet pill is right for you, and which one you may choose for your own weight-loss program.

Remember to do your own personal research on the ingredients and on the products. It’s important to learn as much as you can about any product that you’ll be putting in your body.

In addition, it’s essential that you see your doctor before you start taking a diet pill. Not everyone is medically suited to be taking this type of medication.

Note: For getting the best result, supplements should be taken with caution and under the supervision of a physician. Please consult your doctor before considering any supplements to evaluate the pros and cons, as well as any potential side effects, especially if you have a pre-existing health problem.
