Let’s get started.

best diet pills for men


How Do Diet Pills Work?

Diet pills work in 2 ways. First off most diet pills contain ingredients that will reduce your appetite. Of course, when your appetite is lower you will eat less throughout the day and therefore take in fewer calories which leads to weight loss. As you may know, binge eating and high-calorie foods can really hamper your weight loss goals, appetite suppressing ingredients can change all of that.

The second way they work is through increasing your metabolism so your body burns more fat even when you are sleeping or watching television. This makes it much easier for athletes, bodybuilders and anyone else to lose weight much faster.


What to look for in diet pills?

Every supplement company seems to have a diet pill of some sort, they to do the same thing – help you lose weight faster than you could imagine.

It’s best to ignore all of those claims and go straight to the ingredients, that’s where you will find out if the diet pill is any good or just marketing.

We’ve looked at hundreds of studies and found that the most effective and safest ingredients available are the natural ones.

When looking for a diet pill that actually works these are the ingredients you should be looking for to get the best results.



This ingredient is a fiber that comes from the konjac plant. This fiber expands in your stomach and intestines and makes you feel more full. Therefore you will eat less and take in fewer calories.


Green Tea Extract

This extract which comes from green tea leaves has been proven in studies to increase the rate at which the body breaks down fat. Translation: increased fat loss. [1]

Green Tea


As most of you know caffeine gives you a great energy boost. This increase in energy also leads to an increase in calories burned.


Green Coffee Bean Extract

This extract comes from unroasted coffee beans. Unroasted coffee beans are very high in Chlorogenic Acid which has been shown effective in the “inhibition of fat absorption and activation of fat metabolism in the liver”. This is another very common diet pill ingredient. [2]



5-HTP is sourced from the Griffonia Simplicifolia plant. 5-HTP has been shown to effectively reduce appetite in overweight individuals. Other studies have shown reduced carbohydrate intake along with a reduced appetite. [3][4]


Cayenne Pepper

Cayenne pepper is a bit unique in the fact that it has been shown to increase thermogenesis which lowers fat mass. It was also been shown in this study by Purdue University to reduce appetite as well.  Not a bad 1-2 punch. [5][6]

#4 PhenGold

Phengold fat burner

Next up on our list of the best diet pills for men we have another nice product in PhenQ.

PhenGold has excellent reviews and is a bit different from our first 2 products in that it works in that works in 5 different ways.

PhenGold is made to:

  • Burn fat
  • Suppress your appetite
  • Stop fat production
  • Boost your energy levels
  • Improve mood

When we look at the ingredients for PhenGold we can see why it is so popular. They use Nopal which is a cactus fiber that expands in the stomach to make you feel full so you eat less food just like Glucomannan. They also use chromium picolinate to reduce hunger and prevent cravings.

On top of that, they use capsimax powder which will increase thermogenesis. Thermogenesis is where the body temperature is increased which burns extra calories and increases metabolism. They also use caffeine for increased energy and calorie burning. Overall some really nice ingredients.

Another nice thing about PhenGold is the savings when buying in bulk. With PhenGold you can buy 2 bottles and get 1 free or buy 3 bottles and get 2 free.

If you are looking to buy in bulk this one is the best of the bunch. They also have free shipping on all orders and a money-back guarantee.

This product is made in the USA in a cGMP facility so you know it is of a higher quality. They also don’t use any fillers or dyes, just the good stuff.

#6 Pheonix Fat Burner from Legion Athletics

As far as the ingredients go Pheonix uses 5-HTP to suppress your appetite. Then they use green tea extract, synephrine and forskolin to increase your metabolism and burn fat.

#7 Burn by Core Nutritionals

Burn by Core

Next up we have Burn by Core Nutritionals. This one is a multi-stage thermogenic designed to help you lose weight and get shredded.

When they say multi-stage they mean that it suppresses appetite, increases metabolism, and manages body composition. I think most fat burners make these same claims but calling yourself multi-staged sounds cooler and is better for marketing.

Ingredients-wise this one has some decent ingredients actually using green tea extract, Acetyl-L-Carnitine, forskolin and green coffee bean extract.

This one also has a pretty large dose of caffeine at 250 mg so if you are sensitive to caffeine, you might want to skip this one.


  • Uses 4 proven ingredients to increase fat burning and metabolism.
  • Does not use a proprietary blend
  • Has pretty good reviews online


  • Doesn’t offer much in terms of appetite suppression
  • Large dose of caffeine

Website: CoreNutritionals.com


#8 C4 Ultimate Shred by Cellucor

C4 Ultimate Shred

Next up on our list of the best diet pills for men we have C4 Ultimate Shred.

This one uses Alpha GPC which is gaining popularity as an ingredient that can reduce body fat while increasing lean body mass. On top of that, they use cayenne pepper to suppress appetite and increase fat burning. They also use is Hypurzine-A which also helps to break down fat.

On the negative side, C4 Ultimate Shred does have a pretty large dose of caffeine at 350 mg per dose. That’s about the equivalent of drinking 2 energy drinks so it can be a bit much for some people.

There also aren’t any savings if you are looking to buy in bulk.


  • Uses Alpha GPC, cayenne pepper and Huperzine-A
  • Well known manufacturer
  • Big energy boost


  • Only 1 appetite suppressing ingredient
  • Large dose of caffeine may be too much for some people


#9 Hydroxycut Hardcore Elite

Best diet pills for men

Next we have what is likely the most recognizable name on the list with Hydroxycut. While Hydroxycut has several different fat burning supplements we went with Hydroxycut Hardcore Elite. The name sounds like it will melt off 10 lbs of fat in a week, unfortunately, it won’t.

Taking a look at the ingredients in and they use forskolin and green coffee bean extract to increase metabolism and fat burning. They also use Yohimbe which has been shown to help burn fat and increase libido but it can also have some nasty side effects including anxiety, mood swing and irregular heartbeat.

This product really doesn’t do much in terms of appetite suppression so you will have to rely on the increased metabolism.

There are no stimulants in this product so this could be a big bonus for some people that are sensitive to caffeine and other stimulants.


  • Uses Forskolin and green coffee bean extract
  • Stimulant free
  • Well known manufacturer
  • Not expensive


  • Uses Yohimbe which has bad side effects
  • No savings when buying in bulk
  • No appetite-suppressing ingredients


#10 SuperHD Xtreme by Cellucor

best fat burners for men

Rounding out our list we have SuperHD Xtreme, one of the many fat burners made by Cellucor and this one is the best of the bunch.

This bad boy uses a strong dose of caffeine along with cayenne pepper to boost metabolism and increase your energy level while decreasing appetite.

Unfortunately this product really only has 2 ingredients so there is room for improvement. They also use a proprietary blend so you can’t tell how much of each ingredient is in the product.

Lastly, when you consider that all it is is caffeine and cayenne pepper it’s pretty safe to say that it is overpriced.


  • Boosts energy levels and metabolism and also lowers appetite
  • Well known manufacturer
  • Easy to find online and in stores


  • Missing many key ingredients
  • Uses a proprietary blend



How did we rank the diet pills?

When it comes to ranking the diet pills we rank them based on four main criteria. They are:

  • Ingredients
  • Dosing
  • Reviews
  • Rep
  • Reputation

Ingredients –  This one is the most important ranking factor of all. If the ingredients aren’t any good the product won’t be either no matter who makes it or how they market it. We look for the best ingredients that are backed by science.

Dosing – The dose size is also very important. It’s not uncommon for a manufacturer to make a diet pill that has many of the top ingredients but the dosing on these ingredients is so low that it won’t be effective. This is a way for them to say they have proven ingredients while cutting costs on the amount of those ingredients that are actually in the product. Stingy doses don’t make the cut.

Reviews – Reviews are another ranking factor we take into consideration. We don’t put as much value into reviews as we do the ingredients or the dosing but we do look at them. The reason we don’t value them as much is that there are a lot of fake reviews out there both good and bad. We rely more on trusted review sources that we know are impartial and have a good reputation, they aren’t always easy to find.

Manufacturer Reputation – The last thing we look at is the manufacturer’s reputation. This is a smaller ranking factor because there are some reputable manufacturers that will occasionally put out a bad product and there are also manufacturers that we have never even heard of that put out great products. It is a consideration, but a small one.


Frequently Asked Questions:

What are the best diet pills at Walmart?

That’s a good question. First off I should say the diet pill they have a Walmart are certainly not the best ones on the market. They are usually looking for the cheapest and the easiest to mass manufacture. If I had to choose the best diet pills at Walmart I would go with Trans4orm by Evlution Nutrition. It has some decent ingredients and could deliver some results.

Do diet pills cause anxiety?

They can depending on the ingredients. If there is a large dose of stimulants in it then you can definitely get anxiety. The two main stimulants to watch for are caffeine and synephrine (bitter orange). To be on the safe side you could always go with stimulant-free weight loss supplements.

Do diet pills work on the keto diet?

Yes, of course. The keto diet is a very effective way to lose weight, the right diet pills make it even more effective.

Diet pills versus pre-workout, which is better for weight loss?

Diet pills are definitely the way to go for weight loss. Some pre-workout supplements can be effective when it comes to weight loss but overall the diet pill is made to do one thing, help you lose weight. Pre-workout usually won’t deliver as well in the weight loss department.


Do diet pills have any side effects?

They can, the biggest side effects you will run into will be from the stimulants in them. The stimulants can cause anxiety, jitters, sleeplessness, tachycardia, nervousness, nausea and irritability. The main ingredients to watch for in terms of side effects are caffeine and synephrine.

There is also this case where a 24-year-old man went into afib after taking the fat burner Lipo 6 Black which contains synephrine. He took the Lipo 6 Black and an energy drink (terrible idea) before he worked out and went into afib about a half-hour after his workout. I could have happened from the synephrine but I am sure the energy drink on top of it plus the caffeine that is already in the product didn’t help.

People can also have an allergic reaction to them but that is pretty rare and it depends on what ingredients are in the diet pill and how your body reacts to it.

Anyhow the moral of the story is to be careful and pay attention to what you are putting in your body and what side effects may come along with it. When in doubt, go stimulant-free.



There you have the 10 best diet pills for men on the market today. Be sure to follow the instructions correctly for the best results.

You should also maintain a healthy diet when using diet pills. If you think you can just take some diet pills then slam down a bunch of donuts, pizza and burgers you are probably going to be disappointed. Diet pills will help you lose weight but they won’t do the work for you.
