This female weight loss pill is backed up by ten other ingredients, including vitamins, minerals, plant extracts, and more.

And here’s why:

Each ingredient has a specific purpose, meaning Leanbean supports your body’s natural ability to burn fat and lose weight.

#4 Nobi Nutrition Premium Fat Burner for Women – Best Thermogenic


This fat burner from Nobi Nutrition promotes increased levels of thermogenesis and ketosis – two natural fat burning processes.

In ketosis, your body breaks down stored body fat for energy instead of dietary fat and sugar. It’s a survival state that makes sure you’ve still got energy if you’re not able to get the food you need.

Used in moderation, this state is good for prioritising the burning of fat around your body.

And by increasing your body temperature at rest, thermogenic fat burners claim to increase that calories you burn as well.

You hear that?

Increased weight loss while at rest.

You still have to exercise to make sure you expend more calories in a day than you intake – it’s called running a caloric deficit.

So, a fat burner like the Nobi Nutrition Premium Fat Burner for Women won’t magically cause weight loss.

But it will bump up your daily caloric expenditure a little bit, and every little helps.

Brand Highlights

o The BHB formula helps your body to burn fat as fuel.

o BHB is also linked to boosting your body’s ketones: Great for the keto diet.

o Can be bundled and stacked with other supplements in their range.

o Reduces appetite to further aid your weight loss journey.

o Discounts available when you subscribe to repeat orders.

Nobi Nutrition Fat Burner Ingredients

o ?-Hydroxybutyric acid (BHB): A key component of ketosis – your body produces this compound to give you energy when you’ve not eaten enough sugar. This fat burner contains three types -

o Sodium ?-Hydroxybutyrate

o Calcium ?-Hydroxybutyrate

o Magnesium ?-Hydroxybutyrate

o Magnesium: When magnesium ?-Hydroxybutyrate is broken down, your body benefits from the magnesium. This mineral is often deficient in overweight people.

How the Nobi Nutrition Fat Burner Performs According to our Criteria

o Container size: There are 60 capsules per bottle.

o Ease of use: Take two capsules three times a day before mealtimes – pretty standard.

o Budget: This supplement is the lowest-priced of those we’ve covered so far.

o Discounts: As well as being the cheapest, there are discounts available if you subscribe.

o Where you can buy it: Through the official website, or Amazon.

o Refund policies: Refunds are possible within 60 days.

#5 alli – Best Medicinal Ingredient

Weight Loss Pills 6

Monthly Servings: 120 capsules

alli is an over-the-counter (OTC) form of a weight loss drug that’s usually prescription-only. So if you’re looking for the best OTC weight loss pill, this could be the one for you.

The only active ingredient in alli is Orlistat, a drug designed and approved for the treatment of obesity. As a medicine, Orlistat is placed under heavier scrutiny than supplements like those mentioned above and has more potent effects as a result.

In alli you’ll find a 60mg of Orlistat making slightly less potent than the 120mg which is usually prescribed.

First up, it is designed for people with a BMI over 28, so it is worth clarifying your bodyweight prior to considering alli.

Secondly, the way Orlistat works is to block the absorption of fat by your digestive system. This means that if you eat lots of fatty food while taking alli, the fat will be expelled…

Because of this, Orlistat is usually taken under medical supervision to ensure that the patient understands the risks, and is advised on how to eat a low-fat diet alongside the drug to reduce any unpleasant effects.

Other prescription weight loss drugs to look out for include Contrave and Phentermine.

alli Brand Highlights

? One of the few medically proven weight loss supplements.

? An OTC form of a drug that’s usually only available by prescription.

? Just one active ingredient.

? Suitable for people with a BMI of over 28.

? Widely available.

alli Ingredients

? Orlistat: As a lipase inhibitor, Orlistat reduces the amount of fat absorbed from food passing through your digestive system. This reduction equates to fewer calories ingested and is used to help people with BMI of over 28.

How alli Performs According to Our Criteria

? Budget: alli clocks in at $53 per pack putting at the higher end of the price spectrum.

? Discounts: alli isn’t usually discounted, although it’s available in numerous stores, so it’s worth shopping around.

? Where you can buy it: alli is available from multiple retailers in the US and UK.

? Refund policies: This depends on the refund policy of the store where you buy alli.

? Customer service: As above – this depends on the store in question.

? Prescription or OTC? A prescription is usually required to take Orlistat; however, alli is an OTC form of this drug.

Which Weight Loss Pills Work Best? – How to Decide

When evaluating the best weight loss pills, understanding the ingredients and how they work is perhaps the most critical criteria for rating a product’s effectiveness.

Here’s what to look out for:

Weight Loss Pills 7

There are a few fundamental ways in which diet supplements claim to work.

This includes reducing your appetite so that you consume less food, as well as stimulating your body’s natural processes for converting fat into energy.

Some prescription medicines can even stop certain fats being absorbed by your intestines.

Here’s some credible science on weight loss ingredients –

? In 2010 the European Food Safety Authority (EFSA) noted “a cause and effect relationship” between glucomannan and weight loss.

? In 2011, the EFSA noted a causal link between choline and lipid metabolism.

? A clinical trial found that glucomannan caused body weight reduction in overweight participants.

? The US National Library of Medicine says that Orlistat helps people to lose weight when taken with low-calorie, low-fat diets.

? Papers like this one have linked Synephrine with increased fat oxidation during exercise.

? The ODS state that chromium has links with small amounts of weight loss and body fat.

Weight Loss Pills Side Effects – Are Diet Pills Safe?

All ingredients in natural supplements must meet the GRAS specifications set out by the FDA.

Here’s what you need to know –

? GRAS = ‘generally recognized as safe’.

? GRAS ingredients are “generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use” (source).

? This standard was introduced in 1997.

However, you also need to know that just because an ingredient is GRAS, it may still cause side effects.

Some ingredients commonly found in the best diet pills have also been linked with side effects.

Be aware of the doses you are taking each day and how strong they are. If you’re taking different medications or antidepressants for any reason make sure to speak to a doctor before introducing a weight loss supplement.

Generally speaking, though weight loss products are safe to take if you follow the recommended dosage.

Here are some side effects associated with excessive amounts of ingredients found in diet pills –

? Jitters

? Anxiety

? Bloating

? Gastrointestinal discomfort

? Diarrhea

To reduce the chance of encountering such side effects, take diet pills only as directed.

If you’re pregnant or nursing, we also recommend speaking with a doctor first to ensure that you or your baby aren’t at any additional risk.

How to Guarantee Results from Weight Loss Pills

Weight Loss Pills 8

Buying a weight loss pill is just the first step.

To get the most out of the product you choose, you need to know how to effectively integrate it into your lifestyle.

Here’s how to get the maximum from the supplement you choose…

Take Weight Loss Pills Consistently

To see results, you need to take your diet pills consistently. Product directions usually require you to take one or more doses per day, and consistency is critical in delivering the expected results.

If you only take diet pills once every couple of days, the ingredients don’t have the chance to make their full impact.

Some ingredients, like vitamins and minerals, contribute to ongoing levels in your body, and regular supplementation is key to maintaining these levels.

Building these supplements into your mealtime routine is a great way to maximise the chances of success.

Drink Plenty of Water at Mealtimes

Water aids with absorption of the ingredients in diet pills, and helps to ensure that the capsules reach your digestive system before they start to break down.

Also, with supplements containing glucomannan, water is required to facilitate the expansion of this dietary fibre. As glucomannan expands and takes up more space in your digestive system, you feel the need to eat less as a result.

Good hydration is linked with a host of other positive health effects, too, so drinking water at mealtimes is a great habit to build.

Reduce Your Calorie Intake

Weight loss relies on your total daily energy expenditure (TDEE) being higher than the amount of calories you consume.

On one side of the scale is the need to increase your energy output (see the next section), but people often neglect the need to reduce their energy input.

Reducing your caloric intake means suppressing your appetite in order to eat smaller meals, snack less, and so on.

If you are just starting out and are unsure how to approach your diet, a weight loss calculator can be a useful tool to understand your macros and get you heading in the right direction.

Get Regular Exercise

As we just said, weight loss pills only work if your total daily energy expenditure (TDEE) exceeds the amount of calories you intake.

For this reason, exercise is a vital part of the weight loss regimen, even if it’s low intensity.

Try to incorporate some daily exercise into your routine. If you’re new to an active lifestyle, this could be a gentle walk, a short jog, or a few minutes at the gym. As you get more confident and your strength begins to increase, you can build this up to a longer session.

More exercise means more calories burned and a more favourable TDEE, which paves the way for the weight loss results you’re looking for.

Weight Loss Pills – FAQs

Here are some common questions about weight loss pills. We’ve covered this info in the guide, but here it is in a quick at-a-glance format.

What weight loss pills actually work?

There are a number of weight loss pills that have credible science behind. Orlistat has shown to be effective and has regulatory approval from the FDA.

For those looking for natural weight loss, Glucomannan in doses of 3g per day has been proven to work by european regulatory bodies. Leanbean is an example of a product that uses this safe appetite suppressant in its formula, making it a top pick for customers wanting to lose weight safely.

How to buy phentermine weight loss pills?

Phentermine is a prescription weight loss drug that alters chemicals in your brain in order to help reduce your appetite.

Phentermine is commonly sold under brand names like Adipex-P and Lomaira and is not available over the counter. However, if you have a prescription, you can buy it from online pharmacies like CVS.

Be aware that many supplement manufacturers seek to imitate Phentermine in their brand names and packaging, these products are natural supplements and have no link to this well-known drug.

What is the best carb blocker for weight loss?

Whilst many diet pills focus on appetite suppression and boosting metabolism as a means of increasing your weight loss results, very few can actually claim to be effective ‘carb blockers’. Whilst limited research shows that white kidney beans may have some benefits in this regard; however, the evidence is far from conclusive.

The weight loss drug orlistat has been shown to reduce your absorption of certain fats. However, this does not extend to sugars or carbohydrates.

How to ask your doctor for weight loss pills

Any consultation with your doctor will begin by looking at your specific circumstances.

This will involve an evaluation of your current BMI and whether your weight is having a negative impact on your health.

Before making an appointment with your clinic, it is important to know exactly how much weight you are looking to lose and whether you are healthy enough to go on a diet.

Other important factors will include if you’re pregnant or taking separate medicines such as Wellbutrin.

Do I need to exercise whilst taking a weight loss pill?

Technically speaking, not all diet pills require you to exercise in order for you to see results.

However, your chances of losing body fat quickly will greatly benefit if you exercise regularly. Remember, your daily energy expenditure needs to exceed the calories you consume. Exercise is a key factor in raising your energy expenditure.

Can I take a weight loss pill whilst intermittent fasting?

Yes, but it is best to take pills around food if possible. If this is not possible, make sure to drink plenty of water with them. Bear in mind that the scientific evidence for intermittent fasting is still contradictory, for some it might be more sensible to follow a balanced weight loss program such as Octavia or Noom.

How long should I take a weight loss pill for?

A natural supplement can probably be taken for longer periods than a prescription drug although there is no hard and fast rule. Many people try a weight loss pill for 3-4 months in order to see noticeable weight loss.

Should I buy an OTC weight loss pill or a prescription weight loss drug?

Unless you have a medical need for a prescription weight loss drug, and you have received a prescription from a clinic or qualified medical professional, you should not take prescription weight loss medicines.

These pills are designed to be stronger than OTC products and are unsafe to take without medical need and professional supervision.
