As someone who at various stages in life struggled with some unwanted flabby stuff, I know exactly how easily you can be tempted into buying fat burners you see advertised online.

Unfortunately, there are so many hyped-up products out there, that it can really be difficult to find something that is both effective to increase your metabolic rate and has limited side effects.

Transparent Labs has quite a long list of health and sports supplements, and I had noticed quite a lot of people at my gym using them. One that caught my attention the most is the PhysiqueSeries fat burner supplement, so I decided to do some research.

I had my dietitian give me a review of the labs fat burner ingredients, and then I tested it out with some friends to try and gather some actual results for both cutting and general weight loss.

So, let’s dive right in.

What Is Transparent Labs Fat Burner?

Transparent Labs Fat Burner PhysiqueSeries is a thermogenic fat burner supplement that claims to work by triggering an increase in your metabolic rate.

Without going into extremely boring details of how your metabolism works, let me give you just a really quick explanation of what that means.

Basically, any excess energy you take in is stored in the form of body fat. In the long run, this results in quite a bit of fat storage, and even performance athletes can struggle with their BMI at the low end.

Fat burning is triggered when there is a net negative amount of available energy. While diet and a strict exercise regimen can help, there are ways in which you can help out a bit.

Thermogenic fat loss is one such way, and certain ingredients like green tea extract and caffeine anhydrous can increase your core body temperature. This requires energy, which is sourced from body fat.

And that’s exactly what Transparent Labs says they have created with this fat burner. It’s provided in the form of capsules that can be taken every day.

What attracted me to Transparent Labs Fat Burner supplement is that the packaging is really simple, and the company doesn’t embark on major celebrity endorsements and hyped-up advertising. So, my first step was to review the ingredients with my dietitian.

What Are The Ingredients?

Ingredients

There are 9 main active ingredients that Transparent Labs Fat Burner claims were chosen based on scientifically proven results. Let’s take a look at them one by one.

1. Green Tea Extract

Many people drink green tea for its detox benefits, but in extract form, green tea will also provide a nice boost of caffeine. We did find some studies that have shown some fat burning benefits [1], so there is a good reason to include green tea extract on the Transparent Labs Fat Burner PhysiqueSeries ingredients list. Green tea is also the main ingredient of our best nighttime burners.

2. White Willow

This was a new one to me, but it is a type of bark extract that has been quite extensively studied. It seems like when combined with caffeine it can increase the effectiveness of thermogenesis even when resting [2].

3. Caffeine Anhydrous

Yes, that morning coffee you have to make you wake up could actually be helping with the weight loss process. One of the most common natural ingredients in weight loss supplements is caffeine. One thing to keep in mind, though, is that the more you take in, the less effective it will become. So be careful with supplements if you’re a coffee drinker.

4. Synephrine HCL

This also seems to be a bit of a newcomer to the supplements industry, but there is one study in particular that verified that when sourced from bitter oranges, Synephrine HCL works to increase energy levels in resistance training as well as targeting fat [3].

5. L-theanine

Some people may have seen L-theanine advertised on certain teas in health food stores as a way to help with decreasing stress levels [4]. However, when combined with caffeine, it can help to amplify the effects on fat.

6. L-tyrosine

L-tyrosine is another very interesting amino acid that affects the metabolic rate, specifically during exercise and workout phases [5].

7. 5-HTP

5-HTP is a rather cryptic name but has been shown to influence serotonin levels, which are directly tied to being able to suppress appetite. There are few studies around 5-HTP, but research has shown its effect on weight loss. If a fat burner contains 5-HTP, then it mainly works as an appetite suppressant.

8. Forskolin

This one will be particularly interesting for people who want to achieve more muscle mass definition. A 2005 study revealed positive results for obese men where a significant fat loss was noted [6].

9. Cayenne Pepper

Don’t worry, this fat burner Transparent Labs won’t set your mouth on fire, but cayenne pepper extract is a positive ingredient to see in weight loss supplements. It has been extensively tested as a natural treatment option for obesity, which makes cayenne pepper extract a good option for anyone trying to lose weight.

Does Transparent Labs Fat Burner Work?

This is always the big question when you’re taking some nutrition supplements.

So, after confirming the ingredients with my dietitian, I set out and read through several hundred online reviews and comments in forums and Facebook groups.

Overall, the feedback on Transparent Labs fat burner is very positive, with people noting that it worked well to accelerate weight loss and helped with appetite suppression. That was enough for me to give it a try and see how it would work in a cutting phase.

And I have to say that compared to the results I got 6 months earlier without any fat burner product, I did get to my goals faster. So, let’s take a closer look at the specific benefits.

What Are The Benefits?

Benefits Banner

OK, so let’s analyze what I personally experienced during a 4-week trial where I was going through some targeted exercises for cutting.

I took the Transparent Labs Fat Burner's recommended dose of 2 pills twice a day, which is the same for men and women. During this time, I was exercising 5 days a week, which included a light cardio day.

1. Improved Weight Loss

So, I had planned to reduce my BMI by 4 points over the 4 weeks, and I was using a body fat caliper to get the most accurate readings. The good news was that I managed to achieve my goal a full 4 days sooner than expected.

The last time I went through a cutting phase, it took the full 4 weeks, so that was a nice surprise. Keep in mind that I did my workout as usual, and I cut on most of my carbs during this time.

2. Reduced Appetite

I often try to go through some longer fasting periods where I might skip my breakfast and a morning snack. That will usually mean a good 5 hours in the morning where I can feel hungry and get a bit crabby as well.

What I did find is that when I took Transparent Labs Fat Burner PhysiqueSeries first thing in the morning that I actually got until about 11 am before I started feeling the usual hunger pains. So, from the perspective of appetite suppression, it does seem to bridge a gap.

3. Energy Boost Throughout The Day

I was able to confirm what I saw in quite a few reviews when it comes to some extra energy. By burning extra calories and fat, I did feel like my metabolism was making a good bit more energy available.

Both mentally and physically, I found that I just had a bit of an edge over my normal days.

Any Side Effects?

So, the good news is that I didn’t experience any side effects from the Transparent Labs fat burner, and that matches with the majority of online comments. That being said, I am healthy and don’t have any underlying conditions.

If you have any allergies or illnesses, then it’s always best to check with your doctor. Especially when it comes to sensitivity to caffeine, some people can end up with increased blood pressure and heart rate, which is best avoided.

I also received a few comments about it causing an upset stomach when taken without food. Although I didn't experience this myself, this happens quite often, so it's best to try it after breakfast.

When Should You Take Transparent Labs Fat Burner?

Breakfast eggs and coffee on the table

Transparent Labs recommends that you take 2 capsules twice a day with food. For me, that was with breakfast and then again with an afternoon snack.

I wouldn’t recommend taking it later in the day, as the caffeine dose could end up affecting your sleep. It’s also best to think about reducing your tea or coffee intake by 1 or 2 cups a day to not end up overstimulated.

The more caffeine you take, the less your metabolism will react, which could have the opposite effect of your weight loss goals.

We also did a review on Transparent Lab's magnesium supplement, you can check it out.

4 Tips For Getting The Most Out Of Fat Burners

Tips For Getting The Most Out Of Fat Burners

1. Start With Your Diet

If you don’t fix your diet, then there is no point in taking fat burner products. There really is no way around it, and if you think that you can get rid of fat by sitting on the couch and eating donuts all day, then you need a serious reality check.

Any fat loss goal will be 70% diet and 30% exercise, so make sure you adapt accordingly.

2. Plan For Regular Off Cycles

The longer you take a fat burner, the more your body will become tolerant of the ingredients. That’s why it’s best to take regular breaks. There really is no exact formula to this, but I would generally say that taking one or two weeks off for every 8 weeks of supplementing is the best approach.

Over time, you can see what works best for you and adjust it accordingly.

3. Drink More Water Than Normal

We all know how important hydration is for our fitness levels and performance at the gym. But what you might be surprised to hear is that a thermogenic fat burner will also mean that you process more water.

If you’re in a particularly active phase, then It’s best to add at least an extra pint of water a day.

Never overlook the importance of drinking enough water to enhance your fat-burning benefits. Water is essential for life and optimum health, and without enough of it, your energy, strength, and metabolism suffers.
- Shannon Clark, Sports Performance Scientist

4. Plan Your Exercises The Smart Way

Stay away from cardio. When you’re trying to lose fat, then you need to trigger sustained fat burning processes to lose weight, and that requires higher intensity levels of training. For me, this is generally a time when I switch to lots of high-intensity interval training (HIIT), and I even throw in a regular full-body training day as well.

Here are some other popular fat burners on the market:

About the author

  • I really like this stuff! To be honest it is my first. I was hesitant about taking this because I’m not a pill person but hey there’s a bikini with my name on it that I will be in!! I am losing and shedding those extra curves on these! I don’t have any issues with side effects, my cravings at night are not as intense as prior to taking this pill and I sleep a whole lot better than ever! Thank you Isaac for the thoughts.

  • After a few days of using this product, I can say that it works pretty well! If it were not for the accidental access to your blog, Isaac, I wouldn’t have known about these products. To put things in perspective, I haven’t been having as many cravings, whereas I constantly have something in my mouth before. And I can have something small in the morning like a small bowl of fruit or two hard boiled eggs and feel completely satisfied for hours! I sleep so well with this stuff also. I have a crazy schedule and stress eating is so damn real for me, but this has truly helped and I am so thankful for that!

  • I’ve probably use this product for about 8wks now after having introduced to it in Isaac’s post. And I am pretty much done with my 1st bottle. I have noticed some changes in my weight. And let’s be honest, I could be more active and gym involved and actually could have lost some more! But “stay at home dad” you know how that goes in this society. I have lost about 5 pounds and honestly I take 1 pill at night or sometimes 2. I’m not really sure on the directions because it says 1 thing on the bottle and another on here. I don’t notice any changes in my sleep. I do have a bad case of insomnia so I just take a melatonin along with it. The pills aren’t too big and easy to swallow. Glad to discover this!

  • So it has been a while now after purchasing this with the blessing of Isaac’s words and this is what I experienced so far. I sleep like a baby and wake up refreshed not sluggish. Take 1 hour before I want to fall asleep. I have experienced weight loss, but I am following a nutrition plan to couple this with and start out walking 4 miles every morning during weekdays, combined with a complete exercise gears. After work out and by the end of day I have not noticed I walked 8000-10000 steps! I have lung complications and a mild case of asthma. So I need to take inhaled steroids. I have tried everything and had considered surgery. These were my last ditch efforts as I could never lose more than 5 pounds total which would go up and down and fluctuate so bad. I have tried other ways to reduce my extra curves and you name it, even a medical weight loss plan. All super strict following and exercising. Nothing more than 5 pounds either way. I am not a doctor, but this definitely works for my body! Love this product and am reordering once I am out of stock. Will continue with the combo till I hit my goal!! Hope to keep you posted.

  • I’ve only been on these 4 days. It took me a while to purchase as I was having doubts, until I stumbled upon Isaac’s post. I’m not sure about losing weight yet but I have noticed that I’m not bloated in the morning and my stomach has been flatter. It’s not like a diuretic or anything. I’m not sure how it works. My sleep! However, it has never been this way ever since I can remember. It has been amazing! I have so much trouble sleeping in past. I would sometimes take up sleeping pills at night to help me sleep but to no avail. But even then I would wake up 2 or 3 hours later. With this, I take it and I am passed out ALL night! Like magic! I do not wake up groggy either as I did with my previous pills. They are easy to swallow, and have no taste. I am now a fan of your for sure! Hope to learn more from you Isaac.

  • First, I would like to say thank you Isaac for taking the effort in sharing your thoughts. Okay. This product works great. But first, let’s be honest with ourselves guys, there is NO such thing as MAGIC PILLS. Nothing will work for you if you don’t make a slight lifestyle adjustment. That’s the reality. I have been taking these pills for the last 3 months and I definitely love it. It started a little slow, because it takes time for your body to adjust, but ever since my sleep has been amazing. To make things a whole lot better, I have lost 10 pounds! I cannot believe it. It has helped me with my sleep quality, bloating, gas problems and has erased my constipation issues. I haven’t experienced any negative side effects per se so I hope you guys have not as well. I suggest that you eat a light dinner early and take the pill about an hour before bed. Be patient and watch the magic unfold. To better sleep for us!

  • A little background about myself, I am a heavy eater at night because I work a graveyard shift. That is not helping my weight loss journey at all that I could only have so much self-discipline. Before, I was starving come late nights and I would cave on my way home. Junk food is all that’s open that late so I would cave and go to sleep with a fat burger in my gut when I went to bed. I decided to give this a try since it had great words from you Sir Isaac. By the way, the first night I took it, it was a wonderful surprise. I haven’t had success with these types of pills before! Well, I took it the break before I left and I was NOT hungry and because I didn’t feel starved half to death. I was able to drive right past jack in the box and go straight home crawled in bed and had no issue falling asleep like I normally do! Holy! I feel like this is going to be the extra push I need to stick to my diet plan. Even when I woke up 6 hours after falling asleep, I still wasn’t hungry even though I’d normally want to rummage through my food for a snack. The desire just wasn’t there anymore and it was a really nice feeling. I am going to report back in the future to see if it added an extra boost in reducing these unwanted fat because it certainly helps everywhere else. It’s the first pill that seems to do just as I want it. Thank you.

  • I have only used this product twice when I first read it here in Isaac’s, but they don’t stink like most pills. It’s also a 2-month supply. I have noticed my late night snacking has decreased. I usually take a prescription sleep aid that I will be taking with it tonight. I was hoping I would be able to substitute the product for my prescription. I will have to find out if it does help me in this matter. With all the positive thoughts from you Sir Robertson, I am excited about the results.

  • I have been using these pills for about a month now since I found it out here, and I have to say I have never been satisfied with the results before from using a product! Due to my work schedule, I have to do my strenuous physical activities in the evening, which would often “work me up” and make it hard for me to go to bed. These pills help me relax and help me sleep better; not to mention, the extra boost to my metabolism does help. Since I have started using these pills in early this year, along with making sure to eat my veggies every day and exercise moderately, I have lost almost 15 pounds. Will definitely be buying these again once I ran out of stocks. Keep informing us Isaac.

  • I have been a loyal reader of Sir Isaac and whenever I want to go through a change in my life, I often seek his posts for advice. Now, I bought this product because again, I want to change my life. Before, I was unable to fall asleep and stay asleep, lose weight and feel rested. After taking this product the first night, it didn’t make me feel tired. So I thought it’s not going to work, but the next thing I know, my alarm was going off. I actually slept the entire night! Amazing!! I don’t wake up feeling groggy or tired like other products I have used before! No restlessness and I’m sleeping every night like a baby! This will now be a part of my night regime from now on. I will be getting this again soon. I am still your fan Isaac. Thanks!
