With thousands of different appetite suppressants for sale online it wasn’t easy writing this list.

I tried about 20 of the best sellers and picked the ones that had real scientific evidence backing them to suppress hunger.

It was really hard to find products that only suppress your appetite so some of the products below will also help to boost your energy and burn fat as well as keep your appetite under control.

My number 1 pick is real miracle worker! (I stumbled onto it by accident and now I love it and recommend it to all my friends.)

(Top Pick!) Phen24 – The All In One Appetite Suppressant And Weight Loss Pill

Without a doubt, Phen24 is one of the best appetite suppressants you’ll find online.

It helps to suppress your appetite 24 hours a day so that you can stop snacking and easily stick to your diet.

It’ll also keep you energized which is very helpful when you’re eating less and exercising.

Phen24 is more than just an appetite suppressant.

It contains a total of 20 well thought out ingredients that’ll help to boost your energy, burn more calories and lose weight faster.

The makers have created a day and night time formula, so you get 2 bottles in a box.

The daytime formula contains energizers like caffeine to keep you alert and awake and the night time formula contains ingredients to help you sleep better. (A good nights sleep is essential for weight loss and keeping your appetite under control.)

Here’s how the Phen24 daytime formula puts a blocker on your appetite:

  • Phen24 contains a concentrated dose of caffeine anhydrous. In one study people who consumed caffeine in the morning ate 10% less calories at breakfast.
  • Cayenne has been added to put a spicy curb on your appetite. This study showed that people who ate cayenne before their next meal ate an average of 66 fewer calories. Cayenne is also a thermogenic fat burner that revs up your metabolism and helps your body burn through an extra 200 calories per day!
  • And lastly the morning formula contains an ingredient called Phenylalanine. When you consume this ingredient it releases a hormone called Cholecystokinin which tricks your brain into thinking you’re full!

As well as suppressing your appetite the morning formula also contains other ingredients to boost your energy and help you lose weight.

Now let’s look at the night time formula:

Evening times are the hardest for a lot of people when it comes to snacking because studies show that this is generally the time when your will power weakest.

If you find you’re snacking a bit too much at night time then the Phen24 night formula is for you.

The Phen24 night formula contains 2 powerful ingredients to keep your hunger at bay.

  • First of all it contains Glucomannan, a super fiber from the Konjac plant. This amazing ingredient expands in your stomach taking up space and making you feel full! It was even featured on an episode of Dr Oz

  • The Phen24 night formula also contains an ingredient called Chromium Picolinate. Chromium increases insulin sensitivity so that your body absorbs more glucose from the food you eat so you get more energy from less food which reduces hunger signals so you feel fuller for longer and stay energized.

The combination of Glucomannan and Chromium works well and helps to eliminate night time snacking completely.

I used to love nothing more than chilling on the sofa and watching Netflix with a bunch of snacks.

It was only after I started using Phen24 that I was able to give up the snacks and stick to my diet plan.

I’ve always struggled with cravings and used to find that I could do just fine during the day but when night time came I just couldn’t resist a fridge raid to get some snacks while I was watching Netflix or a movie. My cravings completely went away.

My constant hunger was causing me to gain weight and I was beginning to hate the direction my health was going and how I was looking. No matter what I tried I just couldn’t stop eating! I bought Phen24 and it’s been a total lifesaver. I barely snack at all now and it’s helped me stick to a lower carb diet full of healthy vegetables and nutritious food. I’ve lost over 20lbs already and fell like I’m getting my health and life back in order and beginning to feel confident in my appearance again!

Phen24 also has:

  • Telephone support
  • Worldwide shipping
  • 60 day 100% money back guarantee
  • A free workout and nutrition guide

This is my number 1 recommendation for snackers, overeaters and anyone who wants to get rid of that little gremlin in their belly constantly begging to be fed.

Phen24 usually costs around $74.99 per box and one box will last you a month but they sometimes have special offers or discounts where you can get it cheaper.

I was lucky enough to get mine for 20% off.

(Number 2) PhenQ

PhenQ is made by the same company as Phen24 but it’s a little bit cheaper at $69.95.

As an appetite suppressant it’s a little more basic but still very powerful.

PhenQ will also help you burn fat and feel more energized too!

Here’s why PhenQ is number 2 on this list of the best appetite suppressants:

  • PhenQ contains an ingredient called Nopal. It comes from a cactus like plant and it’s chock full of fiber so when taken with a meal it helps your body to slow down the digestion process which gives you a steady release of energy and suppresses your hunger.
  • PhenQ also contains an ingredient called Capsimax which is a more potent form of Cayenne. If cayenne can help you eat an average of 66 fewer calories per meal then Capsimax should be even more effective at suppressing your appetite and helping you lose weight faster.
  • With the added caffeine to get you through energy slumps and keep you going you’ll find you can go longer between meals without feeling hungry or the need to snack.
  • And finally we have Chromium. The ingredient that suppresses your hunger signals by helping your body absorb more glucose from your meals keeping you energized and less hungry.

PhenQ also contains ingredients to help you lose weight like “a-lacy’s reset” which is a combination of Alpha Lipoic Acid and Cysteine.

One study showed that participants who consumed ALA were able to lose an extra 1.52 pounds more than placebo users without making any lifestyle changes.

With over 190,000 customers and a 60-day money back guarantee this is a good choice if you’re looking for something to suppress your appetite and help you lose weight.

The only real drawback is that because it contains caffeine you don’t want to take it past 6pm because it’ll disrupt your sleep so it’s not great as a nighttime appetite suppressant.

The reviews of PhenQ are generally very positive with many claiming it’s helped them lose weight and suppress their appetite:

I bought PhenQ to help me lose weight and was amazed at how much it has suppressed my appetite. I used to snack a lot while I was at work at my desk but when I took it in the mornings I was able to go until lunch time with nothing but a black coffee! It gave me a nice steady energy too and helped me lose 2 stone with 1 bottle.

Combine PhenQ with a diet full of fibrous vegetables and protein and you will be surprised at how quickly your appetite disappears.

Tip: Because it contains caffeine try not to take it past 6pm and combine it with a scoop of whey protein for a powerful appetite curbing combination!

1 bottle of PhenQ lasts around 30 days and they often have discounts and special offers running on the official website here.

(Number 3) Instant Knockout

Number 3 on this list of the best appetite suppressants we have Instant Knockout.

Instant Knockout is a product specifically for men to squash their appetite and kick fat to the curb.

It was originally made to help fighters keep their appetite under control and get in shape before fight night.

Instant Knockout is recommended by UFC legend Diego Sanchez and MMA coach Greg Jackson.

Here’s what they have to say about it:


Greg Jackson is the coach to fighters like Jon Jones, Holly Holm, Rashad Evans and Andrei Arlovski.

Instant Knockout will knockout your appetite and lay the smackdown on your stored body fat! (Sorry for being cheesy.. I couldn’t help myself. 😊)

In all honesty, this is a really good product and well worth considering if you’re a man.

Women can use it too but they may find the stimulants a little too strong.

Here’s how Instant Knockout will suppress your appetite.

  • The Green Coffee bean extract is a more potent form of caffeine to keep you energized and help you go longer between meals without feeling hungry.
  • GTF Chromium helps your body absorb more glucose from meals so you get more energy from less food helping to keep you full and energized.
  • IK also contains the powerful Glucomannan which expands in your stomach taking up space and making you feel full!
  • The cayenne reduces your appetite and helps your body burn an extra 200 calories per day, so you get rid of hunger and lose weight faster!

Instant Knockout is quite an intense product and is a great choice if you work out intensely because the green coffee extract really gives it a kick.

And if you don’t already workout then this could be just the thing you need to get up and get your butt to the gym!

As an appetite suppressant I.K contains 4 proven ingredients to knock your appetite down a few notches.

It costs $59 which is very reasonable considering it’s packed with more than 10 ingredients to help you burn fat and suppress your appetite.

There’s 3 reasons why I love Instant Knockout. 1 – It gives me the energy I need for a killer workout. 2 – Every time I begin to gain a little weight I use this and get right back in to shape fast. 3 – It stops me feeling so hungry all the time. Whenever I use it I don’t feel the need to eat for at least 5 to 6 hours. I did make the mistake of taking it around 9pm once for an evening workout and didn’t get to sleep until about 4am. Work sucked the next day. This is my go to product for whenever I need to get in shape quick. Now I have my mates trying to borrow mine so I told them to get their own!

Instant Knockout is suitable for men and women and it comes with a full 90-day money back guarantee!

(Number 4) Whey Protein

Did you know that protein is a natural appetite suppressant?

It’s true.

In one study participants who upped their protein intake from 15% to 30% ate an average of 441 less calories per day.

By increasing their protein intake they naturally felt fuller and ate less!

Another study found that men who increased protein to 25% of their total calories were able to reduce cravings by 60% and get rid of night time snacking.

Protein also helps you to lose weight because your body burns more calories digesting protein than it does fat or carbohydrates.

One study showed that by increasing your protein intake your body will burn an extra 260 calories per day without you having to do anything.

That’s the equivalent of an hour of moderate exercise!

The best thing you can do is to eat more protein in your diet from natural sources like;

  • Egg whites.
  • Meat and fish.
  • Beans

But sometimes it can be difficult to get enough protein in your diet when which is why I recommend the fast whey protein.

Tim Ferris the author of “The 4 Hour Body” recommends getting 30 grams of protein within 30 minutes of waking up in the morning for better health and weight loss.

You can easily do this with a scoop of whey protein.

My favorite whey protein powder is Gold Standard and each scoop contains 24 grams of protein!

Protein also contains the essential amino acids your body needs for good health and repair after a workout.

That’s why when I use Phen24 I also take a scoop of the Gold Standard whey protein!

You can get the Gold Standard whey protein cheap on Amazon here.

(Number 5) Psyllium Husk

Imagine that your stomach is an empty bucket just waiting to be filled with food.

Now imagine that you filled the bucket halfway up with sand before eating.

You’d only have to eat half as much to feel full right?

Well that’s kind of how psyllium husk works.

Like Glucomannan, Psyllium Husk is a super fiber that can double in size when it gets wet.

Take a scoop of this with a glass of water 15-20 minutes before a meal and you’ll already begin to feel full before you start eating.

And because it’s pure fiber it’ll slow down the digestion of the carbohydrates you eat so you’ll get a longer lasting supply of energy, even though you ate less.

Psyllium Husk is a fantastic pre meal filler appetite suppressant that contains zero calories and it’s super cheap!

This is the Psyllium Husk product I use.

(Number 6) 5-HTP

5-HTP increases the amount of serotonin that your body produces.

Serotonin is known as the happy hormone.

It’s the thing that makes you feel happy after you’ve eaten a high carb meal.

It’s the reason we call carb heavy foods like pizza “comfort food”.

Studies have shown that low levels of serotonin can increase carb cravings which explains why we get an insatiable hunger for junk food when we’re trying to diet.

By supplementing with 5-HTP you should begin to feel happier and your cravings should go away.

Some people swear by 5-HTP and think it’s the best thing since sliced bread and some say it doesn’t do a thing.

It could be that 5-HTP is only effective at suppressing appetite in those who have low levels of serotonin.

Here’s what people are saying about 5-HTP as an appetite suppressant:

So, if you’re feeling a little low, constantly hungry and finding it hard to stick to your diet then 5-HTP is well worth a try!

5-HTP is relatively cheap too. This is the best 5-HTP supplement available right now.

My #1 5-HTP pick has some great reviews on Amazon here!

(Number 7) KetoBHB

Note: KetoBHB is a product that only appears to be available in the US right now.

Number 7 on my list of the best appetite suppressants we have KetoBHB and this product is best combined with a ketogenic or low carb diet.

Ketogenic Diet: Under 20 grams of net carbs per day.

Low Carb: Under 50 grams of carbs per day.

Moderate Low Carb: Under 80-100 grams of carbs per day.

KetoBHB contains an ingredient called Betahydroxybutyrate aka exogenous ketones.

When you eat under 20 grams of carbs per day your body begins to metabolize your stored bodyfat and produce things called ketones.

Ketones are an energy source your body uses when glucose is low.

When you keep your carbs low and start producing ketones you’ll notice:

  • Your appetite goes away.
  • You have stable energy.
  • Your blood sugars become steadier.
  • You lose weight fast.
  • You think more clearly.
  • Your skin becomes smoother.

One of the main benefits of getting your body to run on ketones is that your hunger almost completely disappears.

Many people who follow a ketogenic diet only eat once or twice per day..

How’s that?

Well even a skinny person has over 70,000 calories worth of fat on their body that can be metabolized into ketones so instead of feeling the need to eat your body can run efficiently on your stored body fat as it has a constant supply of fuel for energy.

So where does KetoBHB come in?

Well some people struggle to get into a state of ketosis as it can take days or even weeks.

KetoBHB helps you get there within hours.

This means that you might be able to get the appetite suppressing benefits of the ketogenic diet without having to reduce your carbs to less than 20 per day.

For best results I would recommend keeping your carbs under 80 grams per day if you’re going to use this product.

KetoBHB provides your body with ketones so you can get the appetite suppressing benefits of a ketogenic diet without having to follow the diet so strictly.

The Best Appetite Suppressants Stack

If you combine a few of these products together in a clever way you can almost completely switch off your appetite.

Here’s what I found works best:

Step 1: Take the Phen24 “Day Formula” in the morning with a scoop of whey protein.

Step 2: 20 minutes before each main meal or whenever you’re feeling a hunger pang take a scoop of psyllium husk with a glass of water.

Step 3: Take the Phen24 “night formula” at about 6pm with dinner to get rid of night-time cravings.

If you’re finding that dieting is making you feel a little low or even depressed, then consider adding in some 5-HTP to boost up your serotonin levels.

And if you’re willing to keep your net carbs under 80 grams per day (the lower the better) then supplementing with KetoBHB will work wonders for suppressing your appetite and helping you lose weight fast.

7 Tips To Reduce Your Appetite

Here’s some tips you can start using right away to help keep your appetite under control:

  1. Drink more water: Sometimes we mistake thirst for hunger. So, the next time you begin to feel a craving down a big glass of water and see how you feel 10 minutes later.
  2. Fill up on veggies: A bowl of low carb and fibrous veggies before a meal. Vegetables like broccoli and spinach are low in carbs, high in fiber and very filling!
  3. Keep blood sugars stable: Stick to slower digesting carbs that don’t spike your blood sugar. Foods like oats, non-starchy vegetables and beans are full of fiber and take longer to digest so they provide a slower release of energy. The more stable your blood sugar the less hunger you’ll feel
  4. Consider a ketogenic diet! By keeping your carbs under 20 per day you train your body to burn your stored bodyfat for fuel. With a constant supply of energy you can go long periods without feeling hungry!
  5. Increase your protein intake: Protein is a natural appetite suppressant.
  6. Fancy a treat? Consider a low carb option. There’s a healthy alternative for almost every food you can imagine.
  7. Exercise! Exercise that lasts longer than an hour with a high intensity has been shown to decrease the appetite hormone ghrelin and increase the appetite suppressing hormone Leptin. If you snack during the day then consider a morning workout. If you’re a nighttime snacker then an evening workout might be better for you!

Are Appetite Suppressants Safe?

Here’s some things to consider for your safety before using appetite suppressants.

  • If you’re on medication, then speak with your doctor first to make sure the ingredients won’t affect your meds.
  • Make sure you don’t under eat! The appetite suppressant stack I talked about above works so well that on some days I barely at a thing and when I checked how many calories I was consuming I was only at about 750 for the day! If you’re trying to lose weight then at a minimum you should eat around 1,000 calories per day.
  • Be careful if you are sensitive to stimulants. Some of the products above contain stimulants like caffeine which can increase your heart rate. If you have heart problems then consider one of the stimulant free options like 5-HTP, Psyllium Husk or Whey protein.
  • Appetite suppressants could influence your blood sugar so if you’re a diabetic then make sure you keep an eye on your blood sugars. Personally, I find that my blood sugars become more stable when I use the stack above.

FAQs About Appetite Suppressants
