Firefighter Fitness and Metabolism ... Part 2




How to Make Your Body Burn More Calories.

Here is the low down on weight gain/loss. 
Metabolic Rate is the rate at which the body burns up calories. A body that consumes 2500 calories a day, and burns 2500 calories a day will stay at the same weight. A body consuming 2500 calories daily but burning only 2000 will gain weight at the rate of about 1lb a week.

This may explain why that ‘lucky’ person across the table from you does not get fat from all that junk food; they consume less calories than they burn.

You can do quite a lot to speed up your metabolism – the secret of burning calories lies in knowing what determines your metabolic rate and what you can do to influence it.

1) Basal Metabolic Rate (Metabolism or BMR) — This is the amount of calories you burn just by being alive – even when you are lying down, doing nothing. BMR accounts for approximately 60% of the calories burned for an average person.

2) Burning Calories with Activity- This is the energy used during movement – from lifting your arm to driving your car to cleaning the windows. This accounts for approximately 30% of the calories burned by an average person.

3) Dietary Thermogenesis — The ‘thermogenic effect’ described as meal- (induced heat production – the calories burned in the process of eating, digesting, absorbing and using food.


You can influence all these factors, and speed up your rate of burning calories using some, or all, of the following tactics:

1) Build Muscle—Increase the amount of muscle in your body. For every extra pound of muscle you put on, your body uses around 50 extra calories a day. In a recent study, researchers found that regular weight training boosts basal metabolic rate by about 15%. This is because muscle is ‘metabolically active’ and burns more calories than other body tissue even when you’re not moving. If you need help getting on track with a fitness program, you can download my FREE 28-page FireRescue Fitness Quickstart Program here.  

2) Move More-Although the average person burns around 30% of calories through daily activity, many sedentary people burn around 15%. Simply being aware of this fact – and taking every opportunity to move can make quite a dramatic difference in the amount of calories you burn. Aerobic exercise should also be performed regularly not only to burn calories but also to work the heart.  Try this, wear a pedometer around the station, see if you can get above 5000 steps in a day.

In addition to the actual amount of calories burned during exercise – studies have shown that after sustained, high-intensity exercise (like that in the 28-page FRF Quickstart Program) you burn more calories for several hours. Try the program here.

3) Eat Smaller and Often-There is some evidence to suggest that eating small, regular meals will keep your metabolism going faster than larger, less frequent meals. There are two reasons why meal frequency may affect your metabolism. First, levels of thyroid hormones begin to drop within hours of eating a meal, and metabolism slows. Second, it may be that the thermogenic effect of eating several small meals is slightly higher than eating the same amount of calories all at once.  Provided your small meals don’t degenerate into quick-fix, high fat, high sugar snacks, eating little and often can also help to control hunger and make you less likely to binge.

To find out how many calories you are burning each day, and how many you are eating - try to log your food. There are plenty of websites that allow you free access to calorie databases. All you need to do is create a profile. I have used www.Fitday.com which is a free website that has some great options to help you chart your daily progress.  You can also download many free apps on your phone.  Try to log a couple of days, I think you would be surprised at what you find out about how many calories your consuming.

Firefighter Fitness and Metabolism

What is Metabolism?

You may often here around the firehouse someone say "I have a slow metabolism."  Usually these individuals are a little on the larger size and often like to joke about their size.  Unfortunately these people are at a very high risk to keep the trend of heart related Firefighter fatalities in tact.  I'm not saying that larger individuals cannot perform the job, in most cases they are great firefighters.  What I am saying is that there is more to the picture than a "slow metabolism."

There are a large number of individuals that believe the reason they are overweight has nothing to do with their appetite, and/or level of activity. They assume it is an inherent problem with their “metabolism”. So today I wanted to clear the air around the firehouse (and other houses) about what metabolism really is.

Taber’s Medical Dictionary defines Metabolism as: The sum of all the physical and chemical changes that take place within an organism; all energy and material transformations that occur within living cells.

My definition: The bodies use of nutrients and oxygen to produce energy; measured in calories.

What is RMR or BMR?

BMR or RMR is the number of calories the body needs to maintain basic bodily function. This represents 55-60% of a person’s metabolism. The other 30-40% is the energy cost of being active and the remaining 5-10% of Metabolism is Thermo-genesis, which is the body’s response to changes in the environmental temperature.

Metabolism varies between individuals due to:

• Body Composition (Fat vs. Muscle)

• Body Weight

• Age

• Gender

Metabolism can and will change as a result of weight loss, caloric restriction, change in body composition (body fat) and exercise. When one loses weight their metabolism will typically decrease. Remember one of the variables in metabolism is weight. The engine (your body’s vital organs) must work harder for a heavier individual.

Aerobic exercise burns calories but does not have a long-standing effect on metabolism; it is temporary. Lean body mass (muscle) is metabolically more active even at rest. Please note this is not saying that aerobic activity is unnecessary in the process of weight management. In fact, research now shows that the combination of resistance training (building muscle) and aerobic exercise (burning calories) is the most effective means for losing weight.

This is as simple as it gets:

FOOD INPUT (calories) is either  used as energy or stored as fat.

The more active you are the more your food will be used as energy, not stored as fat. Point being, get active and stay active. If you aren't currently following a fitness program I recommend trying the FireRescue Fitness 28-day Quickstart Progrm, you can get it here for FREE.
