Welcome to my best pre-workout fat burner review for 2023.
Over the last year my team and I’ve tested nearly 20 thermogenic pre-workouts, and evaluated each on performance, ingredients, taste, results and value for money. It’s been A JOURNEY.
Take it from a guy who went from 21% body fat to 13%…
As soon as I started taking a thermogenic pre workout, I noticed a real boost: I could lift heavier, run longer, and recover faster – all while burning more fat and maintaining muscle mass.
Was it the only reason I lost body fat? No.
Was it the push my lazy A** needed to finally break through plateaus and reach my goal? 100% yes.
YOU are going to benefit from all that experimentation.
Pre-workouts vary more than any other supplement. Sometimes I felt like my face WAS MELTING. Others had literally 0 effect aside from giving me sour duck face. I’ll lay out everything for you, so you know before you buy and get real results fast.
Here are our top picks along with who we think would benefit most from taking them.
Top 7 Pre Workout Fat Burners for Weight Loss (2023 Update)
PhenQ is a revolutionary new fat burning pre-workout that not only helps you burn calories, but also attacks the root causes of fat itself: fat production, low mood, and appetite.
According to a recent study, people taking PhenQ lost more than 7% of body fat and gained 3.8% muscle mass compared to a placebo.
If you’re looking for a safe pre-workout with proven ingredients that help you gently lose fat without feeling like your face is melting, PhenQ is exactly what you’re looking for.
It’s more of an all-around supplement, meaning it works for any fitness level, any workout, at any time. You’ll definitely feel more of a gentle push before your workout and safe, gradual results, rather than the Mr. Olympia I’M A BEAST BABY feelings of the crazy pre-workouts.
Here’s how it works:
Most supplements target one area of weight loss. PhenQ attacks 5. Not only do you burn more calories during every workout, it also contains ingredients shown to suppress appetite, regulate fat production, boost mood, and enhance energy.
In the gym, that means more weight, more reps, and more endurance. At home, that means fewer cravings and more desire to hit the gym again the next day. I don’t know about you, but I get CRANKY when I eat less.
It’s not going to make you superman in the gym, but it will attack weight on all fronts, leading to real results fairly quickly.

Cellucor C4 Ripped pre-workout energy supplement for men and women (fruit punch flavor) is my #1 choice for serious bodybuilders, athletes, weight lifters, or anyone who wants a pre-workout that HITS HARD.
First time I took it, I felt like I stepped on the tracks and got whacked by a freight train. This is that face-melting stuff you take when you’re trying to burst through a plateau and break personal records.
I DO NOT recommend this for beginners. Only take it if you’ve taken pre-workouts before…or you’re adventurous.

I’m not much of a runner, but I noticed a real difference on my first jog. At the point where I’d normally get winded, I still had legs. That ALONE is worth the money for me.
Unlike pretty much every other thermogenic pre-workout, RAW Synergies included Ashwagandha, an herb that’s shown to reduce stress, regulate cortisol, and enhance endurance. It’s what pro runners, cyclists, and endurance athletes use to increase their VO2 Max (basically, how far they can go).

If you’re new to working out, take half a scoop. That’s all you need to run farther, burn more calories, and get in shape faster. If you’re a pro, take two scoops.

What to Look for in a Thermogenic Pre Workout Fat Burner
Most modern supplements should attack fat in multiple ways like more energy, more endurance, fewer cravings, etc.
Avoid pre-workout supplements that only focus on a single aspect, like energy, at the cost of performance and pumps. Stick with formulas that do at least 3.
For example, give you more energy, boost your metabolism, and spur muscle growth. Anything less is a rip off.
Thermogenic pre-workout powder and regular pre-workout energy supplements may have a lot of similarities in ingredients, but they are fundamentally different.
For instance, pre-workout supplements are designed to boost metabolism and may contain ingredients to counter the effects of reduced appetite. Thermogenic also often contains less caffeine than regular pre-workouts.
On the other hand, pre-workout energy supplements promote focus during exercise and may contain ingredients, such as nitric oxide, to promote nutrient delivery and protein synthesis.
The main ingredients you’ll often find in thermogenic pre-workouts include caffeine (increase fat burning and metabolism), green tea extract, CLA or conjugated linoleic acid, L-carnitine (for metabolism and energy production), and capsicum/cayenne.
The best thermogenic pre-workouts feature a fully-disclosed label and are also not underdosed for the safety of people taking them.
Value vs. Cost
It is important to invest in high-quality thermogenic pre-workout powder to keep up with the latest body conditioning techniques. Cheaper fat burners are often packed with fillers and are mass-produced so they provide little nutritional value.
But high prices do not always mean the fat burners are made of quality ingredients. So, always read the label and weigh value over cost.
5 Tips to Improve the Effects of a Fat Burner
1. Find a Solid Fitness Plan and Stick to It
A high-quality fat burner may make your journey towards weight loss more accessible, but it’s essential that you also have a solid fitness program and stick to it. Without exercise, the associated energy boost is wasted.
2. Eat Enough Protein
Protein helps boost satiety hormones and reduce the hunger hormone. This leads to a reduction in hunger and helps you lose weight. Taking enough protein will also help you maintain lean muscle mass.
3. Take Your Fat Burner at Strategic Times
Fat-burning supplements can suppress your appetite and give you energy. Timing your dose right will help you get the most from them.
The best time to take a stimulant fat burner is upon waking up or half an hour before training. This kicks the fat-burning process into gear and raises your energy. People sensitive to stimulants can take their fat burner before midday, so they will still have time to wind down before sleep time.
4. Cycle Your Fat Burner
Cycling (you take a supplement for a set time and have another time off) fat-burning supplements help ensure that your body processes the ingredients to its utmost advantage.
Taking fat burners on a repetitive basis may cause the body to become desensitized to some ingredients – a backfire to your goal of losing weight.
5. Get More Sleep
Sleep deprivation can make a dieter “metabolically groggy.” A study done at the University of Chicago found that when dieters cut back on sleep over two weeks, the amount of weight they lost from fat dropped by about 55%. They felt less satisfied after meals and hungrier, which zapped their energy.
FAQs About Pre-Workout Fat Burners
Does PreWorkout help burn fat?
Yes, the best pre-workout for weight loss can help you burn fat. It works not by triggering your body to burn fat directly but by helping you accomplish your goal of boosting your exercise performance.
Is it better to take a fat burner before or after a workout?
The best time to take a fat burner is before your morning workout, possibly about 30 minutes before breakfast. Taking your fat burner in the morning will also kick-start your day so you can do a more intense workout.
Can you take fat burners without exercising?
Yes, of course. High-quality fat burners work without exercise, although their effect is much better when you work out. Fat burners work without exercise because it stimulates thermogenesis – a metabolic process by which the body burn calories to generate heat.
Final Verdict: Which One Should You Buy?
As you can see in the list above, there are great thermogenic pre-workout supplements available on the market today. But our top pick for the best overall fat-burning pre-workout would be the PhenQ Fat Burner.
The PhenQ is hands down one of the best pre-workouts you can buy at its price point and has a solid ingredient profile. What makes it stand out from other fat burners in this list is that it has a unique blend of ingredients and contains the trademarked formula called α-Lacys Reset®.
This ingredient alone fires up the body’s thermogenesis and accelerates metabolism, so you can burn more calories quickly than taking other thermogenic pre-workout products. Other ingredients you’ll find in this product are a blend of capsicum, niacin (vitamin B3), caffeine, and piperine that help you slim down.
If you want something that has a little more oomph right away for intense gym sessions, go with Cellucer C4 Ripped. It’ll be the best workout of your life.
We also like that Cellucor C4 Ripped is available in incredible flavors, including Tropical Punch, Raspberry Lemonade, Icy Blue Razz, Fruit Punch, Cherry Limeade, and more!
PhenQ is currently my #1 recommendation based on all fat-burning pre-workouts that me and my team researched and tested.
It took our team a lot of trial and error, but none of the weight loss supplements get close to the power of this excellent thermogenic pre-workout. It uses the right ingredients, is safe, and has proven to help you lose fat.
