Best Fat-Burner

Burning fat and losing weight are two things most people wish were easier in life. Unfortunately, most people struggle to achieve this on a daily basis, no matter how hard they try. After all, setting goals for yourself is way easier than putting in the time and effort to achieve those goals.

The truth is, there’s nothing easy about losing weight or burning fat. It takes a combination of a healthy diet and regular exercise — not to mention the time, energy, and effort it takes to maintain it long-term. In fact, that’s a large reason why people struggle to make the necessary changes.

The good news is you can receive a much-needed helping hand when losing weight or burning fat, thanks to the wide range of fat-burning supplements available on the market today. They won’t replace the need for a healthy diet and regular exercise, but they do help you get results.

So, what are fat-burning supplements?

Fat-burning supplements contain a variety of ingredients designed to help the body burn more fat. They work in a number of ways, but most fat-burning supplements either intensify thermogenesis, stimulate lipolysis, enhance athletic performance, or a combination of all three.

Thermogenesis is a metabolic process that involves burning calories to produce heat. It’s a process that’s stimulated by exercise, diet, or environmental temperature. Lipolysis, on the other hand, is a metabolic process that involves breaking down stored fat and using it as energy.

In addition to inducing thermogenesis and lipolysis, many fat-burning supplements are designed to improve your athletic performance — either by giving you energy, increasing strength, or helping your recovery. This makes it easier to keep up your regular, daily exercise routine.

Benefits of Fat Burners

Fat burners benefit the body in a variety of ways. Not only do they enhance your metabolism — both through thermogenesis and lipolysis — but they suppress your appetite. This makes you feel fuller after eating a meal, helping you avoid packing on those extra calories every day.

In addition to that, they help increase muscle strength, enhance insulin’s fueling of hard-working muscle, buffer muscles during and after workouts, stimulate growth factor, increase training intensity, and stimulate anabolic hormones for a more effective and efficient exercise routine.

By burning the calories you do eat, using stored fat as energy, and avoiding eating unneeded calories, your fat-burning goals become much easier. When you factor in the additional benefits to your athletic performance, you’re able to burn fat and lose weight from all necessary angles.

It’s important to note that fat-burning supplements won’t do all the work for you. Many people say burning fat and losing weight is 75% tied to your diet and 15% tied to your physical activity. Fat-burning supplements are there to help you with that extra 10%, when utilized correctly.

How to Choose the Right Fat-Burning Supplement

Anyone interested in investing in a fat-burning supplement is going to be met with a wide range of options. The truth is, the fat-burning supplement market is booming with different formulas — some of them useful, some of them useless, and some of them straight-out dangerous. With that said, it’s important that every consumer not only knows what to look for in a fat-burning supplement, but also what to avoid. The last thing you want to do is spend your hard-earned money on something that doesn’t work — or worse, something that puts you in harm’s way. Don’t worry, we’re going to detail some of the most important things to look for and some of the things you want to avoid when searching for your next fat-burning supplement. By doing a little research and taking your time before purchasing, you can make a safer and better decision.

Best Overall

Burn Lab Pro

by Opti-Nutra Ltd.

Burn Lab Pro is easily our favorite formula on the supplement market today. The ingredients are designed to help you burn fat faster and easier than with diet and exercise alone, and also help you retain muscle mass that you would’ve lost without it. It’s an all-in-one fat-burning formula. It’ll boost your workout intensity and endurance, support muscle growth and recovery, protect and preserve lean muscle gains, burn more calories during a workout, suppress appetite, stabilize energy, and break down fat cells for energy — instead of using them for muscle. The formula contains five ingredients — ForsLean (Coleus forskohlii), Capsimax (Cayenne pepper), HMB (Hydroxymethylbutyrate), NutriGenesis® GTF Chromium, and BioPerine® (Black pepper). It costs you $59 for a one-month supply or $177 for a four-month supply.

Fat Burner Supplements FAQ

We’ve talked a lot about fat-burning supplements. Not only did we detail what they are and how they work, but we’ve discussed the benefits, how to find the right formula for you, and even mentioned some of the top-rated fat-burning supplements available on the market today.

By now, you’ve learned a lot about the fat-burning supplement industry. Don’t worry, it’s perfectly normal to still have questions and concerns. In fact, it’s better to ask questions to ensure you understand exactly what you’re putting in your body.

Hopefully we can answer some of those questions below.

How does the body naturally burn fat?

The natural fat-burning process is fairly easy to understand, though it gets more complex the more you break it down. In layman’s terms, we lose weight when we burn more calories than we consume and we burn fat when we force our body to use stored fat as energy.

While fat is necessary for normal functioning of the human body, too much fat can slow us down. When fat builds up, it needs to be stored one way or another. To make room for the extra fat, fat cells are forced to multiply and even increase in size. This is what we don’t want.

Eventually, the enlarged fat cells start to release fat at a slower rate, especially when you’re not active and don’t need the extra energy. It’s only when we start eating better and start exercising more that we teach our bodies to use that stored fat. Of course, supplements help us get there.

Do fat-burning supplements actually work?

No fat-burning supplement will help you directly burn fat, but they will give your body the nutrients it needs to ensure an effective and efficient natural fat-burning process. So while they do work, they aren’t a magic solution that burns fat without any effort on your part.

Many people suggest that 80-90% of the fat-burning process is dependent on your diet and exercise routine, while fat-burning supplements help with the other 10-20%. When utilized properly and as-directed, supplements can certainly help — but there’s more to it than that.

How do I get the most out of my fat burner?

In order to get the most out of your fat-burning supplement, it’s imperative that you follow a strict diet plan and exercise routine. Without making the necessary lifestyle changes, you’ll never see the results you want to see when burning fat, losing weight, and getting the body you dream of.

With that said, anyone can make good use of the right fat-burning supplement. Even those that feel they’ll never reach their desired weight and body type, it’s 100% possible if you’re willing to put in the time and effort required. It won’t always be easy, but it’ll always be possible!
