What’s the Best Way to Calculate One’s BMR? | Q+A

 

Question:

Is there a more sophisticated equation used to calculate one’s BMR? Or is it only weight/height?

-Matt O. 

 

Answer:

In fact, there are! Most equations include gender and age in addition to height and weight.

“Basal metabolic rate is the amount of energy that is required to maintain basic body functions such as heartbeat, breathing and maintenance of body heat while you are asleep.”

One of the most popular equations to calculate an adult’s basal metabolic rate is the Harris-Benedict, which is as follows:

  • * Women: 655 + (4.35 x weight in pounds) + (4.7 x height in inches) – (4.68 x age in years)
  • * Men: 66.5 + (6.23 x weight in pounds) + (12.7 x height in inches) – (6.78 x age in years)

Used often in the medical and weight loss fields because of its accuracy, and recommended by the Academy of Nutrition and Dietetics is the Mifflin St. Jeor for resting (awake/alert) metabolic rate:

  • * Women: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) – 161
  • * Men: (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5

As any equation is actually an estimation of your needs, you might want to try both and obtain a range that your true BMR probably falls within. Neither of the above take into consideration lean mass versus fat mass, so they aren’t practical for extremely muscled or morbidly obese individuals. For teens, the Schofield method (previously used by the World Health Organization and the US government to formulate the RDAs) has different equations for various age groups.

Measurements of metabolism are usually only done in research laboratory settings but might be conducted by endocrinology specialists. If you are sustaining your weight by eating fewer than 1200 calories per day, you should see your primary care physician.

What Should I Eat While Training for Running? | Q+A

What Should I Eat While Training for Running? | Q+A

Need some advice for training specifically for running?

See what kind of foods may help with your running. No matter if you are training for a marathon or just want to run for fun!

 

Question:

I am by no means an apex athlete or anything.  However, I would like to start to train for an 8k run next March.  I currently do workout with a trainer at the Mt. Prospect Club (who’s awesome by the way).  Can you recommend an eating plan or point me to some resources to help me make the best decision when it comes to nutrition and my training?  Thanks in advance for your time.

-Robert T.

Answer:

Bravo on planning well ahead of time, Robert.  Let’s say that someone starting out jogs at 12-15 minutes per mile.  Your total jog time also depends on how far your current distance is. Conservatively, let’s say that it’s 2 miles. So perhaps you’re moving 24-30 minutes now.  By March, you’d like to be running faster 10-12 minute miles to complete the 8K (5 mile) race in about an hour. Given the time and energy expended, your training diet will not be much different than that for your current workouts with your trainer, but may be comprised of more carbohydrate and ample fluids.

Your initial nutrition plan should be to support your in-gym training & short runs, and to experiment with what foods your gut can tolerate prior to a morning race. Pre-workout nutrition is key so you have the fuel you need to complete an exercise session without feeling drained. Read more about fueling up by clicking here. A bowl of cold cereal with milk might sit well for some individuals but be too slushy for others. An egg white, half an English muffin and half a banana may be all that you need after you wake up to have a successful workout an hour later. Now is the time to try whatever smoothies, protein shakes or bars you might like.

By January, you’ll want to shift your focus to eliminating heavy fats and big meals that make you sluggish, as well as cutting back on alcohol, desserts, and late evening eating. Your muscle cells will be in full training mode to become more efficient aerobically, and they’ll need lots of nutritional support. Balanced lunch and dinner meals mean a plate with 1/2 vegetables, 1/4 starch (potatoes, rice, pasta, etc.), 1/4 lean protein (poultry, fish, lean meats) and a tablespoon of healthy plant fat. Picture a big bowl of shrimp and vegetables stir-fried in oil with just one scoop of rice on the side. For heartier breakfasts on non-run days, you can pick a starch, protein, fruit and milk product such as oatmeal with raisins, nuts and low fat milk. Add a glass of water to your daily fluid intake.

For the few weeks preceding the race, it’s all about ready fuel and recovery as you will probably be running more often and for longer. Read more about recovery nutrition by clicking here. Having adequate glycogen stores will give you sustained energy beyond the blood sugar derived from your most recent meal. The key to muscle glycogen is complex carbohydrate intake, not just before a run, but daily at each meal. Picture the meal balance described in the last paragraph with whole grains, beans, or corn. Then add starch such as pretzels or popcorn at snacks, washed down with another additional glass of water.

“I work out and track my food intake with an online tracker but haven’t lost weight, what do I need to change?”

 

question-answer-color-v-2

I am a 69 year-old woman, 5’6″ and weigh about 160 pounds. I have been trying to lose 10 pounds for about three months with no noticeable change. I work out about 4 times a week and I eat about 1500 calories a day. What should I change? I keep track of my food intake with an online fitness tracker.
Thanks for your help! – Helen

If the “calories in versus calories out method” is not working for you, consider the content and timing of your meals. 1500 calories of processed starch and saturated fat may keep the weight on, compared with 1500 calories from whole grains, lean protein, plenty of produce and healthy fats. Not only do the latter foods satisfy better, they take longer to digest thus keeping blood sugar and insulin levels down. The net effect is more calories burned in order to process and metabolize the food and greater ability to release fat for burning.

Supporting your workouts with meals and snacks at the right times can pay off two-fold. First, pre-loading with a small supply of carbohydrates, such as from a piece of fruit, a half hour before may give you more endurance for cardio and a stronger finish to weight training. Second, eating a main meal within an hour after exercise capitalizes on your increased metabolic rate to burn more fuel.
