no way its level 5. Level 4 maybe. But i would try the treadmill on an incline thats a level 5 possible level 6 if you really incline it

Doesn't matter if your diet isn't on point. Fasted cardio is no more effective for fat loss than cardio in a fed state.

And trying to lose 3% at 6 weeks out is kinda pushing it. You should be stage ready 2-3 weeks out.

Yes, absolutely... am cardio works!

I have been preping for a photo shoot the last 6 weeks and have been running 5k every other morning. First thing when my alarm goes off I take a scoop of no carb protien in water, BCAAs, fat burner (OxyElite Pro), and a thyriod booster. I go back to bed for about 20min then get back up, stretch, and go for the run. The bf is falling off me now :)

I am eating very low carbs (only fruit in the am pre-workout). I have dropped about 5% bf in that timeline and 9 days out now. I am hoping to loose another 2% in that time, and drop all my water (just started sodium depletion). Using the protien and BCAAs, I really haven't lost any weight but I am training very hard to keep the muscle.

People tell me to enter the NPC Physique contest July 8th and I am thinking about it.

You should do great! You look awsome already!!!

im willing to bet you lost more than body fat in 6 weeks if you think you lost 5% bf in under 5 weeks.meaning that is way too quick to lose that % of bf so im assuming you lost a good amount of muscle as well..

As far as fasted cardio is no more effective than cardio done in a fed state. there have been studies done to prove this

Dr. Lonnie Lowery has more info about the Fasted morning cardio could lead to an improved fatty acid mobilization during exercise and increase insulin sensitivity afterwards. This might be true of exercise at a low level of intensity (50-75% of max VO2) since this decreases insulin levels via the stimulation of adrenergic receptors. A lower insulin level can increase fatty acid mobilization.

However, a higher intensity of work (above 75% of max VO2) can actually have the opposite effect. So in that regard a moderate or even low intensity of work would seem to be superior in the morning as far as fat mobilization goes. (Galbo, 1983, Poortmans et Boiseau, 2003)
You have to ask this for Natty fasted might not be the greatest for ASS people could be fine.

AM fasted cardio should be done when you're only interested in body comp and you have either a mesomorphic or endomorphic body type. People do not address the body types of people but throw most in the same scale.

and also please see a nice SCIENTIFIC PEER REVIEWED study done by Brad Schonfield who is not only a researcher, but also a competitive bodybuilder, regarding fasted cardio

Does Cardio After an Overnight Fast Maximise Fat Loss?

A common fat burning strategy employed by bodybuilders, athletes, and fitness enthusiasts is to perform cardiovascular exercise early in the morning on an empty stomach. This strategy was popularized by Bill Phillips in his book, ‘‘Body for Life’’ (23). According to Phillips, performing 20 minutes of intense aerobic exercise after an overnight fast has greater effects on fat loss than performing an entire hour of cardio in the postprandial state. The rationale for the theory is that low glycogen levels cause your body to shift energy utilization away from carbohydrates, thereby allowing greater mobilization of stored fat for fuel. However, although the prospect of reducing the body fat by training in a fasted state may sound enticing, science does not support its efficacy.

First and foremost, it is shortsighted to look solely at how much fat is burned during an exercise session. The human body is very dynamic and continually adjusts its use of fat for fuel. Substrate utilization is governed by a host of factors (i.e., hormonal secretions, enzyme activity, transcription factors, etc), and these factors can change by the moment (27). Thus, fat burning must be considered over the course of days—not on an hour-to-hour basis—to get a meaningful perspective on its impact on body composition (13). As a general rule, if you burn more carbohydrate during a workout, you inevitably burn more fat in the post- exercise period and vice versa.
It should be noted that high-intensity interval training (HIIT) has proven to be a superior method for maximizing fat loss compared with a moderate- intensity steady-state training (10,26,29). Interestingly, studies show that blood flow to adipose tissue diminishes at higher levels of intensity (24). This is believed to entrap free fatty acids within fat cells, impeding their ability to be oxidized while training. Yet, despite lower fat oxidation rates during exercise, fat loss is nevertheless greater over time in those who engage in HIIT versus training in the ‘‘fat burning zone’’ (29), providing further evidence that 24-hour energy balance is the most important determinant in reducing body fat.

The concept of performing cardiovascular exercise on an empty stomach to enhance fat loss is flawed even when examining its impact on the amount of fat burned in the exercise session alone. True, multiple studies show that consumption of carbohydrate before low- intensity aerobic exercise (up to approximately 60% V_o2max) in untrained subjects reduces the entry of long-chain fatty acids in the mitochondria, thereby blunting fat oxidation (1,14,18,28). This is attributed to an insulin-mediated attenuation of adipose tissue lipolysis, an increased glycolytic flux, and a decreased expression of genes involved in fatty acid transport and oxidation (3,6,15). However, both training status and aerobic exercise intensity have been shown to mitigate the effects of a pre-exercise meal on fat oxidation (4,5,24). Recent research has shed light on the complexities of the subject.

Horowitz et al. (14) studied the fat burning response of 6 moderately trained individuals in a fed versus fasted state to different training intensities. Subjects cycled for 2 hours at varying intensities on 4 separate occasions. During 2 of the trials, they consumed a high-glycemic carbohydrate meal at 30, 60, and 90 minutes of training, once at a low intensity (25% peak oxygen consumption) and once at a moderate intensity (68% peak oxygen consumption). During the other 2 trials, subjects were kept fasted for 12–14 hours before exercise and for the duration of training. Results in the low-intensity trials showed that although lipolysis was suppressed by 22% in the fed state compared with the fasted state, fat oxidation remained similar between groups until 80–90 minutes of cycling. Only after this point was a greater fat oxidation rate observed in fasted subjects. Conversely, during moderate-intensity cycling, fat oxidation was not different between trials at any time—this is despite a 20–25% reduction in lipolysis and plasma Free fatty acid concentration.

More recently, Febbraio et al. (9) evaluated the effect of pre-exercise and during exercise carbohydrate consumption on fat oxidation. Using a crossover design, 7 endurance- trained subjects cycled for 120 minutes at approximately 63% of peak power output, followed by a ‘‘performance cycle’’ where subjects expended 7 kJ/(kg body weight) by pedaling as fast as possible. Trials were conducted on 4 separate occasions, with subjects given (a) a placebo before and during training, (b) a placebo 30 minutes before training and then a carbohydrate beverage every 15 minutes throughout exercise, (c) a carbohydrate beverage 30 minutes before training and then a placebo during exercise, or (d) a carbohydrate beverage both before and every 15 minutes during exercise. The study was carried out in a double- blind fashion with trials performed in random order. Consistent with previous research, results showed no evidence of impaired fat oxidation associated with consumption of carbohydrate either before or during exercise.

Taken together, these studies show that during moderate-to-high intensity cardiovascular exercise in a fasted state—and for endurance-trained individuals regardless of training intensity— significantly more fat is broken down than that the body can use for fuel. Free fatty acids that are not oxidized ultimately become re-esterified in adipose tissue, nullifying any lipolytic benefits afforded by pre-exercise fasting.

It should also be noted that consumption of food before training increases the thermic effect of exercise. Lee et al. (19) compared the lipolytic effects of an exercise bout in either a fasted state or after consumption of a glucose/milk (GM) beverage. In a crossover design, 4 experimental conditions were studied: low-intensity long duration exercise with GM, low-intensity long duration exercise without GM, high- intensity short duration exercise with GM, and high-intensity short duration exercise without GM. Subjects were 10 male college students who performed all 4 exercise bouts in random order on the same day. Results showed that ingestion of the GM beverage resulted in a significantly greater excess postexercise oxygen consumption compared with exercise performed in a fasted state in both high- and low- intensity bouts. Other studies have produced similar findings, indicating a clear thermogenic advantage associated with pre-exercise food intake (7,11).

The location of adipose tissue mobilized during training must also be taken into account here. During low-to- moderate intensity training performed at a steady state, the contribution of fat as a fuel source equates to approxi- mately 40–60% of total energy expen- diture (30). However, in untrained subjects, only about 50–70% of this fat is derived from plasma Free fatty acids; the balance comes from intra- muscular triglycerides (IMTG) (30).
IMTG are stored as lipid droplets in the sarcoplasm near the mitochondria (2), with the potential to provide approximately two-thirds the available energy of muscle glycogen (32). Similar to muscle glycogen, IMTG can only be oxidized locally within the muscle. It is estimated that IMTG stores are approximately 3 times greater in type I versus type II muscle fibers (8,21,31), and lipolysis of these stores are max- imally stimulated when exercising at 65%V_o2max(24).

The body increases IMTG stores with consistent endurance training, which results in a greater IMTG utilization for more experienced trainees (12,16,22,31). It is estimated that nonplasma fatty acid utilization during endurance exercise is approximately twice that for trained versus untrained individuals (24,32). Hurley et al. (17) reported that the contribution of IMTG stores in trained individuals equated to approximately 80% of the total body fat utilization during 120 minutes of moderate- intensity endurance training.
The important point here is that IMTG stores have no bearing on health and/or appearance; it is the subcutaneous fat stored in adipose tissue that influences body composition. Consequently, the actual fat burning effects of any fitness strategy intended to increase fat oxida- tion must be taken in the context of the specific adipose deposits providing energy during exercise.

Another factor that must be considered when training in a fasted state is its impact on proteolysis. Lemon and Mullin (20) found that nitrogen losses were more than doubled when training while glycogen depleted compared with glycogen loaded. This resulted in a protein loss estimated at 10.4% of the total caloric cost of exercise after 1hourofcyclingat61%V_o2max.This would suggest that performing cardio- vascular exercise while fasting might not be advisable for those seeking to maximize muscle mass.

Finally, the effect of fasting on energy levels during exercise ultimately has an effect on fat burning. Training early in the morning on an empty stomach makes it very difficult for an individual to train at even a moderate level of intensity. Attempting to engage in a HIIT style routine in a hypoglycemic state almost certainly will impair performance (33). Studies show that a pre-exercise meal allows an individual to train more intensely compared with exercise while fasting (25). The net result is that a greater number of calories are burned both during and after physicalactivity,heightening fat loss.

In conclusion, the literature does not support the efficacy of training early in the morning on an empty stomach as a tactic to reduce body fat. At best, the net effect on fat loss associated with such an approach will be no better than training after meal consumption, and quite possibly, it would produce inferior results. Moreover, given that training with depleted glycogen levels has been shown to increase proteolysis, the strategy has potential detrimental effects for those concerned with muscle strength and hypertrophy.

Eat Before Cardio?
Like most competitors, I was advised early in my career to do an hour of cardio every morning on an empty stomach. It’s what you did. The noticeable lack of energy—and I mean true muscular fatigue and depletion—was just something you had to suffer through. One particular off-season, I decided to work on my mile time. Morning still worked best for my schedule, but body fat loss wasn’t my primary goal any longer. I didn’t want to be bogged down with a heavy meal, but I knew some food would be necessary for performance-based cardio. Eating 15 to 20 grams of carbs made all the difference—I even got to a 6:08 mile. I carried that habit over to pre-contest work and began using 4 to 5 grams of BCAAs along with 10 to 15 grams of carbs after spending a couple of miserable weeks back with fasted cardio. After experiencing the energy boost with pre-cardio carbs, I just couldn’t tolerate the drudgery of fasted work. When I added the carbs back in my heart rate moved higher sooner, I sweat much more, and my real work output was tremendously greater. You’ve felt the difference—strong, effective cardio versus barely being able to put one foot in front of the other. It made sense to me that I was spending a few extra calories to likely use many more as a return in expenditure. And, I knew I was buffering myself against muscle loss at least a little more than with fasted cardio. It’s always a shock to clients when I suggest eating a little before cardio, but finally my theory has been proven. To be fair, there have been studies showing positive, negative, and neutral impact on performance, but type and amount of food has to be considered. Even this study isn’t a perfect match for fat-loss goals—the study group consumed 673 calories. Though hardly the size I’m recommending, the physiological parallels are there. Researchers compared oxygen consumption and substrate utilization both during almost 40 minutes of treadmill work and for 24 hours thereafter. The results were consistent and persuasive. Not only was oxygen consumption higher, meaning more work was done and more calories used, but a higher percent of body triglycerides were used as energy throughout the entire day due to a higher resting metabolism. Imagine when you get those same effects, but relative to a more moderate calorie intake. You’ll not only use more calories than you ingest, you’ll burn more overall calories through the day than if you had performed fasted cardio, AND you’ll feel better doing the cardio. More energy and more effective—not a bad combination. (A. Paoli, et al. Exercising Fasting or Fed to Enhance Fat Loss?

Hi there I am 6 weeks out i need to lose about 3 percent fat, i need to do something more to get this off, does anyone think empty stomach cardio reAlly works?

Hey KK
I have done it many times, and cannot tell a difference between fasted and fed am cardio.
Layne Norton advocates fed cardio, and if you read the report he has sited, it makes sense.
Anacdotal reports from competitors are mixed. Some rely on word of mouth, and broscience, while others rely on the research data.
One thing is pretty clear from the data though. Doing LISS cardio while in a fed state will NOT hinder fat loss progress.

The only reason I like to do fasted cardio is simply so I can eat afterwards and get full, but I do like to take in a nice does of BCAA 20 minutes before I cardio..
Cardio tends to make me hungry (when dieting) so if I eat first, then go do cardio, I get hungry again.. I'd rather stay hungry through my AM cardio then get that small requard after. I make sure to get may macros through out the day and doubt there is any real catabolic musle loss during the 30 minutes I am on the treadmill..

Can't wait to see you in a few weeks!

That is not fasted cardio

Worried about 30 minutes? More like 72 hours.
