Basal Metabolic Rate is the minimal caloric requirement needed to sustain life in a resting individual. This is the amount of energy your body would burn if you slept all day (24 hours).

There are numerous factors that affect BMR. When we are young, many of us have metabolisms that race like furnaces. Simply put, that's why some young people can eat fattening foods all day long, and never seem to gain any weight.

Conversely, by the age of 50, most of us can look at food, and seem to gain weight. However, if we study BMR, we will see that although it takes more work, we can speed up, and tune-up our metabolism.

Muscle requires more calories to sustain per pound than fat. Therefore, by sparing is much lean tissue as possible and by adding as much lean tissue as possible later on; we are able to speed up our metabolism by increasing our BMR, and burning more calories.

Resistance training, and cardio burn calories, and speed up our metabolism. Cardio is especially effective in this area, as it makes our bodies speed up many processes, and increase the secretion of adrenal hormones such as nor epinephrine, and adrenaline. These adrenal hormones create a catabolic effect that increases the speed at which we metabolize blood sugar, and burn fat.

Foods and beverages can actually increase the speed of your metabolism. For example, anything that has a stimulating effect may fall into this category. Products containing caffeine, such as coffee are a good example of this.

Stimulants can cause stress in some people, and as you know success in weight loss is dependent upon keeping stress levels low.

Although stimulants will produce faster weight loss, if they stress the individual, than the individual may be more likely to quit or give up. Therefore, it may be better to lose fat slower, maintaining low stress levels, and therefore increasing the likelihood of success in the long run.

Fasting, or skipping meals will lower BMR. The body automatically responds with a starvation reaction. When your body is not getting sufficient amounts of food, it goes into this starvation mode, or metabolic rates can become so slow; weight loss becomes almost impossible.

Numerous hormones diminish as we get older which affect our BMR. These hormones include DHEA, growth hormone, leutinizing hormone, testosterone in men, and thyroxin (T3). A few lucky individuals do not suffer as great a drop in these hormones as most. However, for the rest of us it's hard work, but we can reverse this trend to some extent by using diet, supplementation, exercise, proper sleep and recovery.

AAS users are able to more easily manipulate hormones exogenously, and we see results far in excess of non users! By using HGH; T3; Clenbuterol and Anabolic Hormones we can achieve bodies the envy of kids half our age!

The higher we can get our BMR, and under safe conditions, the faster we will lose weight and add muscle.

Remember, as your muscle to fat ratio increases, your BMR does go up. An average person weighing 200 pounds, who is leading an active life, will probably be able to attain sufficient weight loss by consuming approximately 2500 calories per day. This amount will vary from person to person, and may need to be adjusted. For example, a very sedentary person may need to consume fewer calories.

Also, as people restrict caloric intake, BMR will automatically go down, because of the hibernation/starvation response.

Once you are successful at tuning up your metabolism, and revving up your BMR, keeping fat off becomes much easier. This also increases your success rate, and of course you will feel younger and more vital.

In closing, you can see the BMR plays a very key role in BF per cent muscle gain fat loss, and anti aging. Therefore, do everything you possibly can to maintain a maximum BMR.
