Why Is Burn The Fat, Feed The Muscle The Best Selling E-Book In Internet History, With Thousands Of Satisfied (And Now Fat-Free) Users In 133 Countries from Algeria to Zimbabwe?
Burn The Fat, Feed The Muscle is the #1 best selling diet and fitness ebook in the history of the Internet. In fact, it’s one of the best selling e-books on ANY subject in the history of the Internet -… And there’s a reason why… Read more
The controversies over cardio for fat loss are endless: steady state versus intervals, fed versus fasted, long and easy versus short and intense, and so on. Obviously there is a lot of interest in cardio training and how to do it right. Sadly, most people are still doing 2 things terribly wrong and it’s killing their results…… As best as I can figure, there are two major reasons why people are still mucking up their cardio programs for fat loss.
REASON #1: NOT ENOUGH FOCUS ON TOTAL CALORIES BURNED
Most people aren’t burning enough darn calories.
Why? Well, I guess they are too busy worrying about the “proper” type of exercise (which machine or activity), the mode (steady state or intervals), the “optimal” ratio of intervals, or the “best” duration.
Some people coast along on the treadmill at 2.3 miles per hour or some similar sloth-like pace and they think that just by hitting a TIME goal, such as 45 or 60 minutes, that with “X” duration completed, they are assured to get the results they want.
On the other extreme, we have folks who have found or created some mega-intense, super-duper short training protocol like the “4-minute wonder workout from Japan.” Just because the workout is high in intensity and it is performed in intervals, they too think they are assured to get the results they want.
What’s missing in both cases is the realization that total fat loss over time is a function of total calories burned over time (assuming you don’t blow your diet, of course).
AND…
Total calories burned is a product of INTENSITY times DURATION, not intensity OR duration.
Too much focus on one variable at the exclusion of the other can lead to a less than optimal total calorie burn and disappointing results. And remember, intensity and duration are *variables* not absolutes! (“Variable” means you can change them… even if your “guru” says you can’t!)
When you understand the relationship and interplay between INTENSITY X DURATION you will find a “SWEET SPOT” where the product of those variables produces the maximal calorie burn and maximum fat loss, based on your current health condition and your need for time efficiency.
REASON #2: TOO MUCH FOCUS ON WHAT TYPE OF CALORIES BURNED
As best as I can figure, there is one whopper of a mistake that is still KILLING most people’s cardio programs and that is…
Way too much focus on WHAT you are burning during the workout – fats or carbohydrates – also known as “substrate utilization.”
This idea comes from the notorious “fat burning zone” myth which actually tells people to exercise SLOWER and LESS intensely to burn more fat.
Hold on a minute. Pop quiz. Which workout burns more calories?
(A) A 30 minute leisurely stroll through the park
(B) A 30 minute, sweat-pouring, heart-pounding, lung-burning run?
Like, DUH!
And yet we have trainers, authors and infomercial gurus STILL telling us we have to slow down if we want to burn more fat??? Bizarre.
The reason people still buy it is because the “fat burning zone” myth sounds so plausible because of two little science facts:
- The higher your intensity, the more carbs you burn during the workout
- The lower your intensity, the more fat you burn during the workout
And that’s the problem. You should be focusing on total calories and total fat burned during the workout and all day long, not just what type or percentage of fuel you are burning during the workout.
It’s not that fat oxidation doesn’t matter, but what if you have a high percentage of fat oxidation but an extremely low number of calories burned?
If you really want to be in the “fat burn zone,” you could sit on your couch all day long and that will keep you there quite nicely because “couch sitting” is a really low intensity (“fat-burning”) activity.
(Of course, “couch sitting” only burns 37 calories per half hour…)
HERE’S THE FAT-BURNING SOLUTION!
In both cases, the solution to burning more fat is drop dead simple: Focus your attention on how you can burn more TOTAL calories during your workout and all day long.
If you want to burn more fat, burn more calories and you can do that by manipulating ANY of the variables : intensity, duration and also frequency.
If you build your training program around this concept, you will be on the right track almost every time.
BUT WAIT – THERE IS MORE TO IT…
Naturally, we could argue that it’s not quite this simple and that there are hundreds of other reasons why your cardio program might not be working… and I would agree, of course. But on the exercise side, the ideas above should be foremost in your mind.
On the nutrition side, you have to get your act together there too.
For example, many people increase their food intake at the same time as they start a cardio training program thereby putting back in every calorie they burned during the workout! Then some of them have the nerve to say, “SEE, cardio doesn’t work!”
Incidentally, this is the exact reason that a few studies show that adding cardio or aerobic training to a diet “did not improve fat loss”: It’s not because the cardio didn’t work, it was because the researchers didn’t control for diet and the subjects ate more!!
It should go without saying that nutrition is the foundation on which every fat loss program is built.
Choose the combination of type, intensity, duration and frequency that suits your lifestyle and preferences the best, and WORK THE VARIABLES to get the fat loss results you want, but whichever cardio program you choose, remember that a solid fat burning nutrition program, such as Burn The Fat Feed The Muscle is necessary to help you make the most of it.

Fat Burners: The Unadulterated Truth
By Tom Venuto, NSCA-CPT, CSCS

If you’ve paid any attention at all to the weight loss industry, chances are you’ve probably heard about some kind of fat burner supplements. The ads that promote these fat burners usually have a very lean model, often with a six-pack claiming incredible fat loss success. These companies would like you to believe that the only way to guarantee fat loss progress is by supplementing your diet with one of their “miracle pills,” and that it is not so much a matter of proper nutrition and hard work.
While I won’t dismiss the fact that there are some ingredients 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 for false advertising, false claims and falsifying before and after photos.
The best you get is a slight thermogenic effect and possibly some slight appetite suppression. A few products might work through other mechanisms like improving thyroid, but if you forgive me the generalization, I consider the effects of all these “fat burner” products to be minutia. In a previous newsletter, I wrote that in my opinion, 97% of your results come from nutrition and training and maybe you get an extra 3% advantage from supplements.
Just so you know those numbers arent something I just pulled out of thin air, lets take an example:
I have reviewed scientific data that EGCG, the active ingredient in green tea extract, if consumed in enough quantity, could increase thermogenesis / metabolic rate by an average of about 75 calories in 24 hours. Since ephedrine was taken off the market, green tea extract appears in many ephedra-free formulas these days. What is a typical calorie expenditure for an active male in 24 hours? lets say 2700 calories per day. 75/2700 = 2.7%. That slight little extra doesnt hurt, especially when its delivered in a healthful package such as green tea, rather than central nervous system stimulants, but its minutia in the bigger picture. Another way to put this into perspective is to make a list of what 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 and metabolism increases while you sit and watch TV? How about for your health? A body that is not moved, rots away. Unlike a car which 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 that yes, 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, details and little things do matter.
I’m simply asking you to put the benefits of any fat burners in proper 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 of the claims made for the product.
How do you KNOW they really work? Are you SERIOUSLY going to take the advertisers word for it? Are you SERIOUSLY going to take someone else’s testimonial as fact? Get verification for yourself by going to the pub med 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).
2. Put it in perspective
With those products that work, such as those providing a small thermogenic effect, put that in perspective as compared to how easily you could burn that many calories with even light exercise like walking or housework. Keep in mind the additional fitness and strength benefits you will obtain from exercise as opposed to doing nothing and popping a 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 benefit ratio, and be certain you know the dangers and contraindications.
4. Read the label and see if the product contains enough active ingredient to even work.
A classic scam is when a “fat burner”product quotes research that a certain inredient boosts metabolism, which might be true. What they may not tell you is that all the research with positive results used 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, even though its nothing more than “label decoration.” Then they have the audacity to invoke the research studies in their advertisements when the amount of the ingredient in their product is no where near what was used in the research!
5. Proprietary blend scam.
Some companies, DONT LET YOU SEE how much ingredient is in the product formula, because it contains multiple ingredients and they say their formula is a “trade secret” aka “proprietary”, so they list WHAT is in the product but not HOW MUCH. If you don’t know how much is in there then how are we (the consumers) supposed to get independent confirmation of the facts and analyze whether this 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, as it is often used to help find areas of research where human study should be pursued, or in the other direction, to trace back the mechanism that makes something work. However, for obesity research in particular, a positive finding in rats does not mean the same thing will happen in humans.
7. Look for more than one human study.
Consider trying a supplement after it has human research that has been replicated by different research groups which are not industry-sponsored. My policy is that I will usually only give a “buy” rating to a supplement when a product has an intitial well-designed human controlled trial published and then similar research has been replicated by another research group that is not supplement-industry funded.
Actually, I think it’s a good thing that nutrition and supplement companies fund and sponsor some of the research. They should. They should not only back up their claims with published clinical trials, they should share 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 the funding source does not necessarily prove bias, if there is only one study available on a supplement and it is company or industry sponsored, I usually take it with a grain of salt and put an asterisk 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 research backing them only help a little, with the fact that many of the ads lie to you about research, exagerrate claims and hide vital information about ingredients, and with the fact that you can do a few more minutes of exercise per day and get the same results for free, how enthusiastic are you about fat burners? Yeah, that’s why I’m not real excited about them either and based on the fact that I use no drugs and no “fat burner” supplements and I compete in bodybuilding – very successfully – I’d say that the assertion, “it takes more than nutrition and exercise to get six pack abs” is patently false.
