![]() By: David Robson Come competition time, the aim of all bodybuilders is to become as shredded as possible, while maintaining hard won muscle size. Becoming shredded, or ripped, depends on a number of variables: a low-fat diet, the right genetics, the correct amount of aerobic work and hard, heavy, weight training.
Indeed, those who take every possible precaution to ensure they arrive at contest time as cut as humanly possible, but find it exceedingly hard to lose the last of their body-fat, might just have the dreaded slow metabolism. But does such a slow metabolism exist, or are some bodybuilders simply inept at managing their pre-contest regime, and committing to the long-term goal of fat-loss. According to some authorities, a slow metabolism can be euphemistically used to describe all of the above, in that when the appropriate rules of pre-contest preparation are followed, results in fat loss should readily present themselves.
Metabolism is a very broad term, which encompasses a wide variety of definitions. Broadly, it can be defined as the ingestion and breakdown of complex compounds, coupled with the liberation of energy, and the consequent generation of waste products. In terms of bodybuilding, and bodybuilders preparing for competition, metabolism of fat is what counts primarily. Metabolism effects bodybuilders in the sense that its inability to function efficiently due to certain variables (diet, training and genetics), prevents the athlete from losing the desired amount of body-fat, which negatively effects their stage presentation, and lowers their chance of winning - the aim of any serious athlete.

Therefore, the key for any pre-contest bodybuilder, is to increase the rate at which they burn body-fat, through activating this aspect of the metabolism. But exactly how is this done?
As mentioned, increasing the body's fat burning potential by activating the metabolism requires that a number of factors are taken into consideration. All of the following pre-competition, or general fat-loss (as these apply not only to bodybuilders), rules, will work wonders when it comes to getting in the best possible shape.
The body will simply adapt to maintaining a low metabolic rate if it has to continually adjust to a sharp decline in calories, for a period, followed by engorgement. This has obvious implications when it comes to losing weight when it counts (pre-competition for example). Attempting to lose fat at a rapid rate will also, inevitably, result in losses in protein, and, as discussed in detail later, a net loss of muscle protein means a decrease in metabolism. Another problem with drastic weight loss, in light of excess weight to be lost, concerns an enzyme called lipoprotein lipase (LPL). LPL is a fat storing enzyme, that increases when calories are dropped at a significant rate. Too much LPL, and one piles on the fat, and will possibly need to diet harder to lose this fat, which might further increase LPL and make losing fat next to impossible. The idea is to maintain a sensible eating plan throughout the off-season, so when pre-contest rolls around, one does not have to severely restrict calories to lose weight.
Stabilized blood sugar prevents the hypoglycemia that occurs when one eats a huge meal and feels tired and lethargic soon afterward, due to low glucose levels to the brain. The body is more likely to store fat when in a hypoglycemic state, due to a spike in insulin levels.
Bodybuilders serious about fat loss should engage in aerobics both off-season and pre-contest, to keep the metabolic fires burning. In fact, aerobics have a triple-whammy effect on fat-loss, in that they stimulate the metabolism, metabolize fat directly as a fuel source, and burn carbohydrate calories, thus lowering the fat-storing potential of these macronutrients. Aerobics can however deplete the body of protein if done too often, or for too long, or both. Therefore, if one witnesses muscle wastage pre-contest, it might be a good idea to cut back on aerobic work to the point where fat, rather than muscle, is being utilized. Walking four-times-per-week for 40-minutes should be sufficient for bodybuilding purposes.
In fact, eating a meal high in protein will stimulate the metabolism by as much as 30%, as opposed to fat or carbohydrates which increase it by around 4%. Furthermore, protein will heighten the metabolic rate for around 12-hours after eating. Eating sufficient protein shouldn't be a problem for most bodybuilders, as it is a fundamental requirement in terms of muscle building, and should be an established part of their nutritional plan.
Beginning the diet early will, furthermore, allow one to eat a sufficient number of calories in the form of carbohydrates and protein, which will lessen the chances of muscle-mass depletion and the resultant drop in metabolic rate.
Dieting too close to competition time (which logically requires dropping calories to low) will send out a signal that the body is approaching a state of starvation, which results in the body shutting down the metabolism to conserve calories for this time of famine. Clearly not what one needs when fat-loss is the aim.
Moreover, and harking back to what was discussed earlier, skipping breakfast will keep the body in a mode of starvation, given it has essentially been fasting over a 8-10 hour sleeping period. Once the body recognizes the fact it needs to hang onto every available calorie, fat loss will be the last thing to occur.
Achieving ones best possible shape depends on a number of factors, including an efficiently functioning metabolism. An under-functioning metabolism can, in fact, thwart anyone's chances of losing sufficient body-fat come competition time. Rather than blame a slow metabolism on genetic factors (which might or might not influence metabolic activity), follow the guidelines in this article, lose fat, and look great!
