Fat Burners – The Unadulterated Truth

QUESTION: Tom. I am currently not using any fat burners.However, in many magazines where I see advertisements for fat burners, they always have a model with a six-pack and the headline is something like, “It takes more than trainingand nutrition to get a six-pack.” Once a person hits a plateau, do we really need fat burners to achieve that “ripped” or “six-pack” look? I am having a really hardtime getting my stomach to look the way I want it, and Ireally respect your opinion, so I appreciate your thoughtson this. Thanks Tom!

ANSWER: The short and sweet answer is NO, you do not ever “need” fat burners.

While I won’t dismiss the fact that there are someingredients in some “fat burner” products that might help a little bit, I take great displeasure in seeing those kinds of misleading headlines as well as the misleading use of models who are often paid to endorse the product even though they may never have even used it (they’re just models!)

Many “fat burner” companies have been sued by the Federal Trade Commission forfalse advertising, false claims and falsifying before andafter photos.

The best you get is a slight thermogenic effect and possiblysome slight appetite suppression. A few products might workthrough other mechanisms like improving thyroid, but if youforgive me the generalization, I consider the effects ofall these “fat burner” products to be minutia.

In a previous newsletter, I wrote that in my opinion, 97% ofyour results come from nutrition and training and maybe youget an extra 3% advantage from supplements.

Just so you know those numbers arent something I just pulledout of thin air, lets take an example:

I have reviewed scientific data that EGCG, the active ingredientin green tea extract, if consumed in enough quantity, couldincrease thermogenesis / metabolic rate by an average of about75 calories in 24 hours.

Since ephedrine was taken off the market, green tea extractappears in many ephedra-free formulas these days.

What is a typical calorie expenditure for an active male in24 hours? lets say 2700 calories per day. 75/2700 = 2.7%.

That slight little extra doesnt hurt, especially when itsdelivered in a healthful package such as green tea, ratherthan central nervous system stimulants, but its minutia inthe bigger picture.

Another way to put this into perspective is to make a list ofwhat other things would burn 75 calories (for 150 lb person:)

  • walk your dog for 15 minutes
  • three times a day, walk for 5 minutes at normal casual pace
  • 30 minutes of ironing
  • bagging leaves and grass clippings for 14 minutes
  • re arrange your furniture for 10 minutes
  • wash your car, 15 minutes
  • vacuuming for 15 minutes
  • 7.2 minutes of walking up stairs (could be spread throughout the day)

Ah yes, but why move your body when you can take the pill andmetabolism increases while you sit and watch TV? How about foryour health? A body that is not moved, rots away. Unlike a carwhich only has so many miles on it and wears out from over-use,people are the only “machines” on earth that fall apart from under-use.

Here’s what any good personal trainer will always tell you: No amount of calorie restriction or pill-popping will ever give you FITNESS. It willl never give you STRENGTH. it will never get you MUSCULARITY. It will never give you FUNCTIONALITY. At best it will help you reduce body mass slightly.

On one hand, I’m tempted to say that everything counts and thatyes, 75 calories here, and 75 calories there, it ALL adds up,because it does. After you’re exercising regularly and all your fundamentals are in place, detailsand little things do matter.

I’m simply asking you to put the benefits of any fat burners inproper perspective and realize that (1) there is no “need” for taking them and (2) the claims made in the ads are often erroneous or exagerrated.

My advice on fat burners:

1. NEVER buy a fat burner unless you get independent verification ofthe claims made for the product.

How do you KNOW they really work? Are you SERIOUSLY going to takethe advertisers word for it? Are you SERIOUSLY going to take someoneelse’s testimonial as fact? Get verification for yourself by (a) Going to the pubmed data base and looking for research (try www.ReleMed.com too, as their search results are very thorough and relevant and they provide links to the pub med citations), or (b) become a member at ourinner circle, go to the supplement forum and look for the product inquestion. if it’s not there, start a new thread and ask if there isresearch supporting the product. We will do the research and independentverification for you in a neutral and unbiased fashion (because we are not affiliated with any supplement companies).

2. Put it in perspective

With those products that work, such as those providing a smallthermogenic effect, put that in perspective as compared to how easilyyou could burn that many calories with even light exercise likewalking or housework. Keep in mind the additional fitness and strength benefitsyou will obtain from exercise as opposed to doing nothing and poppinga pill.

3. See if there are any side effects or health warnings.

With all supplements and especially with prohormones or stronger thermogenics like the ephedrine and caffeine stack,(if you still have access to them), understand the risk to benefitratio, and be certain you know the dangers and contraindications.

4. Read the label and see if the product contains enough activeingredient to even work.

A classic scam is when a “fat burner”product quotes research thata certain inredient boosts metabolism, which might be true. Whatthey may not tell you is that all the research with positive resultsused a large dosage of the ingredient, which might not be cheap.So the supplement company includes a “pinch” or “light dusting”of that ingredient just so they can say it’s in the bottle, eventhough its nothing more than “label decoration.” Then they have theaudacity to invoke the research studies in their advertisementswhen the amount of the ingredient in their product is no where nearwhat was used in the research!

5. Proprietary blend scam.

Some companies, DONT LET YOU SEE how much ingredient is in theproduct formula, because it contains multiple ingredients and theysay their formula is a “trade secret” aka “proprietary”, so theylist WHAT is in the product but not HOW MUCH. If you don’t knowhow much is in there then how are we (the consumers) supposed toget independent confirmation of the facts and analyze whetherthis product is any good?

6. Make sure there is human research, not just rodent research.

In many cases, advertisements cite studies on rats and mice as “proof” under the assumption that the product will produce the same results in humans. Animal research is an important part of the scientific method, asit is often used to help find areas of research where human studyshould be pursued, or in the other direction, to trace back themechanism that makes something work. However, for obesity researchin particular, a positive finding in rats does not mean the samething will happen in humans (here’s a perfect example).

7. Look for more than one human study.

Consider trying a supplement after it has human research thathas been replicated by different research groups which are notindustry-sponsored. My policy is that I will usually only givea “buy” rating to a supplement when a product has an intitialwell-designed human controlled trial published and then similarresearch has been replicated by another research group that isnot supplement-industry funded.

Actually, I think it’s a goodthing that nutrition and supplement companies fund and sponsorsome of the research. They should. They should not only backup their claims with published clinical trials, they shouldshare some of the cost of this expensive research.

However, a basic principle of the scientific method is replication.Other researchers should be able to duplicate the findings.Therefore, while funding source does not necessarily prove bias, if there isonly one study available on a supplement and it is company orindustry sponsored, I usually take it with a grain of salt and put anasterisk next to it while I wait for confirmation from another study. (You might be surprised at how IN-frequently this type of confirmation occurs).

Do you REALLY need “more” than nutrition and exercise??????

Now, when you weigh the fact that even the products with researchbacking them only help a little, with the fact that many of theads lie to you about research, exagerrate claims and hide vital information aboutingredients, and with the fact that you can do a few more minutesof exercise per day and get the same results for free, how enthusiasticare you about fat burners?

Yeah, that’s why I’m not real excited about them either and basedon the fact that I use no drugs and no “fat burner” supplementsand I compete in bodybuilding – very successfully – I’d say that the assertion, “it takesmore than nutrition and exercise to get six pack abs” is patently false.

Train hard and expect success,

    GREAT ANSWER, Iget asked this question every day. I think I will just print your response and hand it out. I have tried fat burners and I get “jittery” then when they wear off I crave carbs for energy.Thanks Dr Dan(Current wt 194, down from 232)

    Thank you for the enlightening reply, Tom. Especially in Mexico where I live and where we’re following the U.S. as the 2nd country with obesity there are hundreds of products with miraculous claims for EASY weight loss. With a lack of efficient regulation from the government and a lot of faith from a population willing to believe in a “no diet, no exercise, no effort” approach to fitness these products are selling like crazy.Congratulations on your work and thank you for making this information available. I just downloaded your e-book yesterday and everything I’m reading makes perfect sense. I can’t wait to begin and better my health while I prove to myself how much I can accomplish and how good I can look!

    What about using supplements in addition to diet and nutrition. I definitely believe what you about train hard and eat right. But you seem to want to take the 180 degree approach to taking supplements because its easier than exercise. I don’t believe you’ve ever stated or gave the thought about eating right, training hard, and using a supplement for a little extra help.

  • February 29, 2008 2:57 pm

    Omar, first, I did not generalize to “all supplements”, this post was specifically about fat burners. There are other supplements that are certainly worthwhile for “convenience” or “nutritional insurance” purposes” and on rare occasion something like creatine comes out which has numerous studies confifrming its effectiveness.second, I actually stated exactly what you asked about supplements for a “little help”. I wrote:“everything counts and that yes, 75 calories here, and 75 calories there, it ALL adds up… After you’re exercising regularly and all your fundamentals are in place, details and little things do matter.”regardstom venuto

    This a topic of great interest to me. In 2007, I experienced a major body transformation through proper nutrition, weight training, cardio, AND taking thermogenics. They were helpful in that I feel like they boost my mood and alertness and help with some appetite curbing. HOWEVER, like an earlier post, I do experience some pretty strong nighttime cravings, and have tried short periods of cycling off of it. When I do this, I feel very tired, lethargic, and lazy, so I start taking it again. I think it is going to take a good week of just pushing through without taking it and drinking lots of water so my body can return to homeostasis and get used to not having this in my system.

    Hello TomWondering what are your thoughts on L- Carnitine? worthwhile?I understand it is good for cardiac health also.Thanks for all the good infoKathy

    L-carnitine is a DUD for fat loss, but yes, there may be health uses and Drs Kraemer, Volek and ratamess did two studies on L carnitine L tartrate which said it might do something to enhance recovery from resistance trainingWe have full research review (with 29 references cited) in the members only area athttp://www.burnthefatinnercircle.com/members/256.cfmtom

    I am just recovering from an achilles tendon tear and did gain some weight when I was restricted from my normal routine of exercise- I have been tempted to use the fat burner “wonder pills” because I am having a hard time losing especially the belly fat- I turned 50 this past year and it seems like nothing is working at this point- but I do believe with your expertise and guidance I will find a way to get back to the shape I used to be. Thanks for your continued research and advice.

    So funny, I just wrote a research paper on (nearly) this exact topic today- fat burners and use in athletes.Thanks for a great article!

    Tom,I was wondering what your thoughts are on CLA as a fat burnerThanks,Janet

  • February 29, 2008 11:18 pm

    Janet, CLA works great if youre a mouse! (see#6 above)I pasted below the most recent review of the research from fall 2007:Conjugated linoleic acid (CLA) and obesity. Public Health Nutr. 2007 Oct;10(10A):1181-6. Silveira MB, Carraro R, Monereo S, Tébar J. Servicio de Endocrinología y Nutrición, Hospital Universitario de La Princesa, Madrid, Spain.BACKGROUND: The term conjugated linoleic acid (CLA) refers to several positional and geometric conjugated dienoic isomers of linoleic acid (LA), of which the trans-10,cis-12 isomer has been reported to reduce adiposity and increase lean mass in mice and other animals when included at the mechanisms by which CLA isomers elicit their effects remain largely unknown. The purpose of this paper is to provide an updated review of the studies performed on animals and humans, as well as to describe the potential mechanisms involved in CLA effects on body weight and composition and metabolism.METHOD: Literature review.RESULTS: Experiments in humans have not been able to show a significant effect on body weight, body composition or weight regain related to either of the CLA isomers. In fact, some studies suggest a tendency towards a decrease in body fat mass and an increase in body lean mass, while some others raise concern about the possibility of deleterious effects of trans-10,cis-12 CLA on lipid profile, glucose metabolism and insulin sensitivity.CONCLUSIONS: Evidence regarding effectiveness of CLA in humans is not concluding.

    Tom, I’m almost completely finished with a package of BSN’s Atrophex and I feel like it was a waste of my money. After taking two “fat burner” products, I’ve concluded that fat burners don’t work. At least, they haven’t worked for me.Sure, I had more energy but I didn’t notice a change in my body fat ratio during my last evaluation in November. The biggest change occured because of practically eliminating my sugar intake and increasing my physical activity. Initially, I started working out with weights, then I discovered Craig’s ballantynesTraining program and have stuck with that for almost six months now. As a result, I’ve gone from 244 lbs to 225. Sorry, I don’t know what my current body fat ratio is, or I would definitely post it here.But I’m pleased to write that my wife says, “You look great! Your arms are big and firm, your waist is trimmer, and your legs look great.”It feels good to hear that from her. My outcome for working out and eating better is to look good, feel better, and live longer. My specific outcome is to achieve a 10% body fat ratio so that I can see muscle definition and to weigh 220 lbs.The reason I decided to share my story is I believe what Tom has revealed about fat burners. I believe that if you implement Tom’s four pillars strategy, you’ll achieve the results you’ve been daydreaming about. The four pillars consist of Strength Training, Cardio Training (Interval Training is best for fat burning), Nutrition, and Mental Training.Tom, thank you for divulging the truth about fat burning supplements and revealing what it takes to take the picture in our heads of how we want to look and feel and make it appear in the real world!God bless you,Ron Hudson
