With the scientifically proven blend of alpha-lipoic acid (ALA), magnesium, and cysteine in the α-Lacys Reset® formula, you should be able to speed up your metabolism and burn more calories faster. In a study published in the medical journal Obesity Reviews, ALA caused significant weight loss [1].

After using PhenQ for four weeks, we had more energy, decreased cravings, and were able to run longer distances during our daily workouts, which ultimately led to a higher rate of weight loss.

"Insoluble fiber adds bulk to food and isn't digested, so it helps increase feelings of fullness as well as the frequency of bowel movements."

How We Tested These Fat Burners for Runners

Choosing the best fat burners for runners isn't a task we take lightly. As avid runners and fitness enthusiasts ourselves, we understand the unique demands and challenges faced by those who hit the pavement regularly. Our testing process was both rigorous and personal, ensuring that our recommendations resonate with fellow runners.

Personal Trials

Several members of our team, including myself, tried out these fat burners during our regular runs. We noted any changes in energy levels, endurance, and post-run recovery. I remember one particular long run where I felt more sustained energy and less fatigue, which I attributed to the fat burner I was testing.

Ingredient Analysis

We meticulously examined the ingredient list of each product. We looked for ingredients backed by scientific research and known to benefit runners specifically.

Feedback from Fellow Runners

We reached out to our local running community and collected feedback on their experiences with these fat burners. Their insights were invaluable in understanding the broader impact of these supplements.

Taste and Mixability

As runners, we often mix our supplements with water or sports drinks. We tested how well each fat burner dissolved and tasted when mixed with various liquids.

Value for Money

We compared the cost per serving, the quality of ingredients, and the overall benefits to determine which products offered the best value for runners.

Safety and Side Effects

Given the increased heart rate and body temperature during runs, we paid special attention to any potential side effects, especially those that could affect a runner's performance or safety.

Consultation with Experts

We consulted with sports nutritionists and trainers to get their expert opinions on the efficacy and safety of each fat burner for runners.

Fat Burner Buyer's Guide

A person using her phone outside

There are many fat burner supplements on the market today, and if you don't choose wisely, you may end up not losing stored fat, breaking your budget, and even having unexpected health problems. So here are the things to keep an eye on.

Ingredients

When buying weight loss pills, it is crucial to know whether they contain ingredients that increase fat oxidation, hasten metabolic rate, or suppress appetite because all of these work differently and might not be suitable depending on your goals.

According to the National Library of Health, you should also note your allergies, sensitivities, and intolerances to prevent adverse effects [6].

Ingredient Breakdown

Let's delve into some common ingredients found in top-tier fat burners:

  • L-Carnitine: A natural compound found in foods like meat and dairy, L-Carnitine plays a pivotal role in energy production. It aids in transporting fatty acids into the mitochondria, where they're burned for energy. This process can assist in weight reduction and body fat decrease.
  • Green Tea Leaf Extract: Beyond its traditional use as a beverage, green tea extract has been linked to enhanced mental focus and weight loss. Its caffeine content can also provide a much-needed energy boost during workouts.
  • Cayenne Pepper Extract: This spicy ingredient does more than just add flavor. It can promote thermogenesis, a process where the body burns calories to produce heat. Additionally, cayenne pepper may foster a healthy gut by promoting the growth of beneficial bacteria.

Dosage

When you decide what ingredients are right for you, make sure they are formulated with the correct dosages. You should prioritize products with no proprietary blends and, ideally, a brand that shows how much of every ingredient is in the fat burner [7].

Value for Money

To maximize your investment, choose a sufficiently dosed product in one or two capsules that does not require repeated ingestions throughout the day. Also, you can opt for a brand that provides a month's supply in every bottle.

Furthermore, to determine how much money you'll spend each day on supplements, divide the price by the number of servings per bottle and multiply by the number of times the supplement must be taken per day.

Transparency in Labeling

In the vast sea of supplements, transparency has become a beacon for trustworthiness. Consumers are now more educated and cautious about what they put into their bodies.

Transparent labeling, which clearly lists each ingredient and its dosage, is preferred over mysterious proprietary blends.

Knowing exactly what you're consuming and in what amounts allows for informed decisions and ensures you're getting the best bang for your buck.

Affordability vs. Quality

It's a common misconception that price always equates to quality, especially in the supplement industry.

While some high-end fat burners offer premium ingredients, there are affordable options that don't compromise on efficacy.

It's essential to research, read reviews, and perhaps even consult with a nutritionist or fitness expert before making a purchase.

Remember, the best fat burner is one that aligns with your goals, budget, and body's needs.

Importance of Diet and Training

It's paramount to understand that no supplement can replace the foundational pillars of a balanced diet and consistent training.

Fat burners are designed to assist and amplify your efforts, not replace them. Ensuring you have a well-structured diet and exercise routine is the first step. Once these are in place, fat burners can provide that extra push to help you achieve your fitness goals.

Speaking from personal experience, you can't simply take fat burners and do nothing workout and diet-wise and expect to see some reasonable results. Exercise, diet, and supplementation should all be considered together.

Otherwise, you will lack results, and most likely, you are just looking for shortcuts instead of a genuine weight loss plan that always works.

FAQs

Why Do Runners Take Fat Burners?

Runners take fat burners to help them lose fat or excess weight more effectively while running. Because many people run to burn fat, these weight loss supplements can help boost metabolism, reduce calorie intake, and increase energy and endurance.

Can I Take Fat Burners Before Running?

You can take fat burners before running to ensure that you have the energy and strength to make it through a challenging run.

Taking these supplements will also assist you in burning more calories during your workouts and throughout the day.

Are Fat Burners Safe For Runners?

Fat burners are generally safe for runners because many of these supplements are derived from natural, high-quality ingredients that are unlikely to cause any adverse side effects.

Also, fat-burning supplements may help improve overall health.

Our Verdict: The Best Fat Burner for Runners

Of all the fat burners we tested, PhenQ proved to be the best fat burner for boosting energy levels and burning calories in both male and female runners.

After only two weeks of use, my clients and I noticed its positive effects on endurance. As we continued to use these supplements over the next few months, we saw significant weight loss and even gains in lean muscle mass in comparison to other fat burners on the list.

We believe PhenQ has assisted us in losing weight by improving our metabolism and boosting our pre-workout for running, leading to higher excretion and energy expenditure, which inevitably caused fat loss in a surprisingly short period of time.
