Let’s Talk About Weight Loss
Weight loss is a multi-faceted topic, and there is no one-size-fits-all solution. Results require consistent work in the gym alongside a healthy diet, good sleep hygiene, and keeping stress levels low. It will require much more than implementing a pre-workout supplement into your routine. When it comes down to it, weight loss is achieved through a calorie deficit, meaning more calories are burned than consumed.
Pre-workout can help with weight loss primarily in three ways:
1. by motivating someone to workout harder and longer,
2. by utilizing thermogenic ingredients to increase fat-burning capacity during a workout, and
3. by acting as an appetite suppressant.
Most often people looking to lose weight create a calorie deficit through a combination of diet and exercise, and pre-workout can help with both of these things. For a pre-workout to be effective, it must be combined with a workout.
What is Thermogenesis?
If you’re after the best pre-workout for weight loss, you may want to know a thing or two about thermogenesis. Thermogenesis is essentially a word for heat production. Thermogenic compounds increase core body temperature which increases fat burning and metabolism and suppresses appetite. Thermogenesis is really where the “fat-burning” language comes from when discussing foods and supplements. An increased metabolism helps us to burn more calories at rest.
Though this is true, thermogenic ingredients likely only slightly improve fat-burning capacity. They may help give you a little boost in burning more calories from a workout, but the impact may be negligible, depending on individual circumstances.
Pre-workout for Weight Loss Vs Regular Pre-Workout
The best pre-workout supplements for weight loss and fat burning will contain thermogenic ingredients, due to the reasons mentioned above.
Look for these key ingredients in pre-workout supplements for weight loss:
- Stimulants: The most popular stimulant most of us know about is caffeine. Stimulants help reduce appetite and increase thermogenesis.
- Another compound commonly found in supplements with caffeine is L-theanine which can help mitigate the negative side effects of caffeine.
- Nootropics: Nootropics, sometimes referred to as cognitive enhancers, can contribute to reduced appetite, improved mood, and focus. Some nootropics have stimulant effects, but not all nootropics are stimulants.
- Caffeine is technically a nootropic.
- Theobromine is another compound sometimes found in pre-workouts that is similar to caffeine in its mood-boosting effects minus the stimulant properties.
- L-Carnitine: L-carnitine is sometimes used as a weight loss supplement and is often found in pre-workout supplements. Some research proves its efficacy regarding weight loss with an effective dose found to be 2 g.
- Acetyl-L-carnitine is a specific type that appears to have additional brain health benefits.
- Thermogenics: As discussed above, these compounds can slightly increase someone’s fat-burning capacity.
Common thermogenic/fat-burning ingredients and their recommended doses used in supplements are listed below. Always follow the dosage instructions listed on your supplement.
- Caffeine anhydrous: 150-200 mg
- Green coffee bean extract: 200-400 mg
- Bitter orange: 50-98 mg
- Green tea extract: 300-500 mg
- Capsaicin: 6 mg
- Black pepper extract (often as BioPerine®): 5-20 mg per day
The most typical pre-workout ingredients we come across in everyday life are coffee and green tea, which research suggests are both effective thermogenic agents that promote weight loss.
Safety and Potential Side Effects of a Pre-Workout Supplement
To avoid or lower the likelihood of experiencing side effects from pre-workout, don’t ever exceed the recommended dose and check with your doctor beforehand if you are on any other medications or supplements.
Be Mindful of Caffeine
Since caffeine is a prime ingredient in many pre-workout supplements for weight loss, the side effects of too much caffeine are a part of the discussion. Some side effects of overconsuming caffeine are jitteriness, heart palpitations, dizziness, headaches, and even anxiety attacks, insomnia, nausea, constipation, rapid heart rate, and an upset stomach.
Everyone has a different tolerance level when it comes to caffeine. Someone who is a regular coffee drinker may not feel the effects of caffeinated pre-workout as strongly as someone who rarely consumes caffeine.
The FDA recommends no more than 400 mg of caffeine to be consumed daily. Any more than that and the likelihood of experiencing negative side effects significantly increases. If you’re also a coffee, tea, or energy drink drinker, you may want to ensure that the caffeine content in your pre-workout does not exceed 400 mg in a day. The amounts vary by brand, but many pre-workouts contain 120-200 mg of caffeine per serving. If you take two scoops (two servings), you could hit the recommended caffeine dose from pre-workout alone.
Another thing to bear in mind is to not use pre-workout with caffeine within 6 hours of bedtime—maybe more than that for people who are sensitive to caffeine. So, if you’re someone who likes to work out in the evening, consider a non-stim pre-workout that still has thermogenic ingredients for weight loss that aren’t caffeine.
Avoid Using Pre-Workout as a Rest Replacement
Many turn to pre-workout drinks and mixes to energize themselves before a workout when they may be feeling too tired or sluggish to work out. If this is you, just remember to consider why you are feeling unenergized in the first place. Is it due to lack of sleep or poor nutrition? While the benefits of regular exercise are tremendous, sometimes our bodies need rest over movement, and that’s okay.
Look for Certifications
Other general things to keep in mind when shopping for fitness supplements are to look for a fully disclosed ingredient label, questionable proprietary blends, certifications of third-party testing and manufacturing standards, and customer reviews.
The Effects of Caffeine on Weight Loss
Anything that suppresses appetite will inevitably aid in weight loss efforts. Studies have revealed that caffeine ingestion 0.5-4 hours before a meal may suppress appetite. Anecdotally speaking, it’s common for people to use caffeine or coffee as an appetite suppressant. However, the extent to which appetite-regulating hormones are impacted is likely small. That said, any bit helps when trying to shed extra pounds.
Price
Pre-workout powders aren’t necessarily cheap, but if you shop around, you can typically find a supplement with good value for your money. For context, anything less than $40 could be questionable and anything above $60 is a bit excessive.
If you’re looking to cut costs but receive some of the same benefits from pre-workout, black coffee can be a good substitute for a supplement. New research by the International Society of Sports Nutrition (ISSN) supports the use of coffee as a performance aid.
Other Tips:
- Most pre-workouts suggest users consume them 15-30 minutes before a workout to reap maximum benefits.
- Pre-workout may make you sweat more due to thermogenic ingredients and beta-alanine, so make sure to remain hydrated throughout your workout.
- Look for certifications like NSF Certified for Sport, GMP, USP, and ConsumerLab.
- Even if using the absolute best pre-workout for weight loss on the market, if not paired with a consistent workout routine and healthy diet, seeing results is unlikely.
Bottom Line: Best Pre-Workout Supplements for Weight Loss
Finding the best pre-workout supplement for weight loss can be a game-changer for anyone looking to optimize their fitness journey. By choosing a thermogenic pre-workout, individuals can ensure they are not only primed to boost energy levels but are also maximizing their body’s fat-burning potential.
It’s important to drink pre-workout formulations that have a well-researched blend of components designed to target body fat. The right pre-workout supplement will support your goals, transforming your workout sessions into a more efficient routine for burning fat and sculpting a toned physique.
