HIGH-INTENSITY INTERVAL TRAINING:
THE OPTIMAL PROTOCOL FOR FAT LOSS?
James Krieger
As exercise intensity increases, the proportion of fat utilized as an energy substrate decreases, while the proportion of carbohydrates utilized increases (5). The rate of fatty acid mobilization from adipose tissue also declines with increasing exercise intensity (5). This had led to the common recommendation that low- to moderate-intensity, long duration endurance exercise is the most beneficial for fat loss (15). However, this belief does not take into consideration what happens during the post-exercise recovery period; total daily energy expenditure is more important for fat loss than the predominant fuel utilized during exercise (5). This is supported by research showing no significant difference in body fat loss between high-intensity and low-intensity submaximal, continuous exercise when total energy expenditure per exercise session is equated (2,7,9). Research by Hickson et al (11) further supports the notion that the predominant fuel substrate used during exercise does not play a role in fat loss; rats engaged in a high-intensity sprint training protocol achieved significant reductions in body fat, despite the fact that sprint training relies almost completely on carbohydrates as a fuel source.
Some research suggests that high-intensity exercise is more beneficial for fat loss than low- and moderate-intensity exercise (3,18,23,24). Pacheco-Sanchez et al (18) found a more pronounced fat loss in rats that exercised at a high intensity as compared to rats that exercised at a low intensity, despite both groups performing an equivalent amount of work. Bryner et al (3) found a significant loss in body fat in a group that exercised at a high intensity of 80-90% of maximum heart rate, while no significant change in body fat was found in the lower intensity group which exercised at 60-70% of maximum heart rate; no significant difference in total work existed between groups. An epidemiological study (24) found that individuals who regularly engaged in high-intensity exercise had lower skinfold thicknesses and waist-to-hip ratios (WHRs) than individuals who participated in exercise of lower intensities. After a covariance analysis was performed to remove the effect of total energy expenditure on skinfolds and WHRs, a significant difference remained between people who performed high-intensity exercise and people who performed lower-intensity exercise.
Tremblay et al (23) performed the most notable study which demonstrates that high-intensity exercise, specifically intermittent, supramaximal exercise, is the most optimal for fat loss. Subjects engaged in either an endurance training (ET) program for 20 weeks or a high-intensity intermittent-training (HIIT) program for 15 weeks. The mean estimated energy cost of the ET protocol was 120.4 MJ, while the mean estimated energy cost of the HIIT protocol was 57.9 MJ. The decrease in six subcutaneous skinfolds tended to be greater in the HIIT group than the ET group, despite the dramatically lower energy cost of training. When expressed on a per MJ basis, the HIIT group's reduction in skinfolds was nine times greater than the ET group.
A number of explanations exist for the greater amounts of fat loss achieved by HIIT. First, a large body of evidence shows that high-intensity protocols, notably intermittent protocols, result in significantly greater post-exercise energy expenditure and fat utilization than low- or moderate-intensity protocols (1,4,8,14,19,21,25). Other research has found significantly elevated blood free-fatty-acid (FFA) concentrations or increased utilization of fat during recovery from resistance training (which is a form of HIIT) (16,17). Rasmussen et al (20) found higher exercise intensity resulted in greater acetyl-CoA carboxylase (ACC) inactivation, which would result in greater FFA oxidation after exercise since ACC is an inhibitor of FFA oxidation. Tremblay et al (23) found HIIT to significantly increase muscle 3-hydroxyacyl coenzyme A dehydrogenase activity (a marker of the activity of b oxidation) over ET. Finally, a number of studies have found high-intensity exercise to suppress appetite more than lower intensities (6,12,13,22) and reduce saturated fat intake (3).
Overall, the evidence suggests that HIIT is the most efficient method for achieving fat loss. However, HIIT carries a greater risk of injury and is physically and psychologically demanding (10), making low- and moderate-intensity, continuous exercise the best choice for individuals that are unmotivated or contraindicated for high-intensity exercise.

More on the power of carb restriction and weight loss! See reference to calorie consumption!
Enjoy!
Teens Triumph on Controlled Carbohydrate Program
Atkins Center - A recent but significant study pokes a large hole in the idea that weight loss is simply a matter of restricting calories(1). Results of the study, conducted at Schneider Children's Hospital in New Hyde Park, N.Y., were presented at a meeting of the Society for Adolescent Medicine in Washington, D.C. Marc Jacobson, M.D., reported on his findings, involving children ranging in age from 12 to 18, all of whom were between 20 and 100 pounds overweight. He found that teens following a controlled carb plan were more successful in their weight-loss efforts than those following a low-fat, high-carb plan, even though the former ate an average of 730 more calories daily.
Members of the controlled carb group were allowed to eat as many calories as they wanted in the form of meat, fish, fowl and cheese, two salads a day and minimal other carbs. The low-fat group ate fat-free dairy products, whole grains, low-fat meats, poultry and fish and many fruits and vegetables. They were limited to 1,100 calories a day. The results speak for themselves: Teens in the controlled carb group lost an average of 19 pounds during a 12-week period; low-fat dieters averaged 8.5 pounds. The controlled carb group also showed a greater decrease in overall serum cholesterol levels and triglyceride levels were reduced by 52 percent, as compared to a 10 percent drop for the low-fat group. High-density lipoprotein (HDL), or "good," cholesterol levels increased in the controlled carb group and decreased in the low-fat group.
Two myths often perpetuated by critics of Atkins were also addressed in this study. Skeptics who don't actually understand the process of lipolysis/ketosis have often stated that the Atkins Nutritional ApproachTM is effective only because fewer calories are consumed. As Atkins followers can attest, they can eat plenty of delicious, whole foods. In the Schneider study, the controlled carb group consumed an average of 1,830 calories a day, 66 percent more than the low-fat group's average, while losing almost 1 pound more per week. Another myth is that Atkins can damage kidneys. Schneider researchers monitored kidney and liver functions and found that they were unaffected by the controlled carb diet.
Dr. Jacobson attributes the weight loss success of the controlled carb dieters to suppressed insulin levels, resulting from carbohydrate restriction. This, in turn, stops the body from "laying down new fat," he says, forcing it to burn fat already accumulated in the body. After three months on a weight-loss plan, study participants followed a maintenance diet that included additional carbohydrates. Six to 12 months later, most of the controlled carb followers had maintained their new weight. The study provides additional evidence for the efficacy of a high-protein, controlled carb weight loss program, specifically for teenagers.

Good stuff. Now here's a question for anyone.
I just got some pure dextrose in the mail from supplement direct. I use this stuff post workout. There is no scoop in it. I've been putting 3 tablespoons in my shake, along with creatine. Is this ok? How many carbs is ok to intake on a cut?
I've seen some guys intake 175 carbs a day on a cut and get ripped. Others say that is too much...

Just my opinion but why are you using such a huge amount of dex after a workout? I have normally read that a protein/carb mix of about 50/50 was more appropriate but must admit I have seen precious little science to back up all these "expert" claims from the BB mags.

eating carbs post-workout invokes an insulin response that helps promote faster recovery and whatnot for muscles right? How much I am supposed to be intaking, is still a mystery. I found out that a heaping tablespoon of pure dextrose is 15 carbs. So I guess 3 tablespoons isnt too bad post workout.
I'm going to watch my weight this week. I made some adjustments and I'll see if the dextrose has a negative effect on my weight.
I agree, I havent seen much science to back this up. So I will be easy on the dex for now

My personal experience with the post workout meal is that I am usually better off without one. Having said that, if I did choose one, it would be MetRx 37Gms of protein, about 24 GMs of Maltodex and almost no fat.
Again no science here, just good results. Just a good MRP.
Good luck
