Fat Burner or Testosterone Booster

To say that the Covid-19 pandemic has changed our day-to-day lives would be an understatement. It has changed how we interact, learn, and work as countries’ guidelines have led to a more virtual existence, both professionally and personally.

Unsurprisingly, more people have become focused on improving their health and fitness. This caused an increase in vitamin and supplement use. 

That said, one of the vitamin and supplement trends is the use of fat burners, which work to speed up metabolism, suppress appetite, and burn fat.

But did you know that some people are relying on testosterone boosters to promote weight loss? But, can testosterone really help you lose weight? 

That’s what we are going to find out in today’s post. Plus, which one is better: a fat burner or a testosterone booster? Would one supplement complement the other? Let’s begin by knowing…

What Does Testosterone Have to Do with Fat Loss?

Testosterone is a hormone that plays an important role in the development of male reproductive tissues. In men, it is believed to regulate libido, muscle mass and strength, fat distribution, and bone mass.

So, is testosterone booster really a magic weight-loss solution that men are looking for? Well, it’s too soon to say. More rigorous and larger studies are needed. 

However, a study published by The European Congress on Obesity (ECO) stated that hormone-deficient obese men could shift their excess weight by taking testosterone supplements.

In the said research, men were given testosterone boosters and they lost an average of 16kg for five years when their testosterone levels were maintained to normal.

Still, there were experts who cautioned the use of supplements to raise testosterone levels due to the risks of heart disease and prostate cancer. Some experts believe that it is always safer and more sensible for men to reduce their weight by working out and limiting their food intake to boost their free testosterone level.

Obesity Linked with Low Testosterone Levels

Separate research published in the Journal of Clinical Endocrinology and Metabolism detailed that obese men, on average, have 30% lower testosterone levels in their body compared to those who are normal weight.

Another observational study at a clinical research center found that over 70% of morbidly obese men suffer from testosterone deficiency and male hypogonadism – a condition where the body does not produce enough key hormones that play role in masculine development and growth.

These just go to show that although scientists are not sure why testosterone levels are lower in men with obesity, they point toward certain processes.

First, that the belly fat has high levels of aromatase, an estrogen synthase enzyme (converts testosterone hormone into estrogen female sex hormone). 

Second, estrogen activity and high aromatase lessen the production of GRH. Lack of gonadotropin-releasing hormone leads to lower levels of luteinizing hormone. Consequently, this reduces the testosterone production in the body, according to researchers from the Department of Medicine and the National Center for Infertility Research.

Put simply, it appears that having excessive belly fat suppresses testosterone levels in men. How about fat burners, then…

Do Fat Burners Work to Help You Lose Weight?

The answer? Yes, but don’t expect miracles. Despite their name, they don’t make fat cells go up in smoke but high-quality fat burners do drive weight loss in other ways. Here’s how they work to help you lose weight:

  • Reduce the amount of fat your gastrointestinal tract absorbs
  • Increase your metabolism, which then leads to burning more calories
  • Suppress your appetite

However, it is still best to talk it over with your doctor if you are considering taking these supplements, especially for a longer period. Do know that the ingredients in testosterone boosters or fat burners that you are planning to take may interact with your medications and cause serious problems.

That is why it is important to ensure that your doctor is aware. Also, start at a low dose. It does not mean that the more ingredients you consume, the better the results you will see. Most supplement manufacturers do have serving directions and guidelines so you know the dose that is best for you.

Now, on to the best fat burners and testosterone boosters in the market today.

How We Decided Our Picks

When assessing the usefulness of these fat burners and testosterone boosters, we looked at various factors.

For fat burners, we consider:

Fat Oxidation

Since fat burners are meant to burn fat, we consider fat burners that cause fat oxidation. It is the end-use conversion into human energy. The most popular ingredients that help increase the amount of energy your body burns from stored fat include l-carnitine and green tea extract.

Increasing Metabolic Rate

This can be described as whether a product burns more calories. So, we consider fat burners that contain ingredients that help increase metabolic rate, like cayenne peppers.

For testosterone boosters, we consider:

T-Boosting Ingredient

Due to a large number of testosterone boosters in the market, choosing the best one for you can be difficult. For the ExpertFitness team, we consider the ingredients list.

For instance, products that contain D-Aspartic Acid (amino acid) help stimulate the body’s ability to produce testosterone hormone in multiple pathways. Another powerful T-boosting ingredient is the Ashwagandha that helps the body handle stress by not only stimulating T production but reducing cortisol levels as well. On the other hand, we avoid those that contain synthetic ingredients to avoid side effects.

For both, we decided our top picks based on:


Some supplements hide their ingredients in proprietary blends so users won’t know the exact amount of each. That is why we pick products that are transparent with their formula, which also means you know how effective their fat burner or testosterone booster is.

The Bottom line: Which One Works Better to Speed Up Fat Loss?

So, if you are having trouble dropping your last few pounds, motivated to work out or get off the couch, and maintaining a ripped physique, taking a fat burner or testosterone booster could help crush your fitness goal.

But as to which one is better, a fat burner or testosterone booster? Our answer would be the Fat Burner. This does not mean that testosterone boosters are not effective. They are. In fact, they help with muscle building and help you meet your training demands.

Yet, if your goal is to lose weight, then fat burners are designed for that. You may also combine these two naturally-sourced supplements to create a balanced environment to craft muscle and shed that extra pound.

Don’t also forget to focus on the basics of a successful long-term weight loss, which are:

1. Healthy, portion-controlled food

2. Being physically active

3. Managing stress levels

4. Getting enough sleep each night, and

5. Self-monitoring (especially your weight)

Best of luck on your weight loss journey!
