Guys, if
you want to beef up your muscles and keep them strong, try eating an extra-lean
burger after your workout. Middle-aged men looking to maintain muscle as they
age may need even more meat than some current health guidelines recommend, according to new research published in the journal Applied
Physiology, Nutrition, and Metabolism.
Researchers at the Exercise Metabolism Research Group at
McMaster University looked at 35 middle-aged men (around 59 years of age), and
found that six-ounce servings of 85 percent lean ground beef had better results
for maintaining muscle mass than the three-ounce portions recommended in
Canada’s Food Guide. (The USDA similarly recommends two to three ounces of meat
per serving.)
The
researchers looked to see how much meat was needed for “muscle protein
synthesis,” a process that helps repair, maintain and grow skeletal muscle.
What the researchers found was that while the smaller portions of red meat might
prevent protein deficiency, they don’t necessarily preserve muscle mass—something
that’s important for men looking to prevent muscle loss as they age.
Previous
findings published in Current Opinion in Clinical Nutrition and
Metabolic Care show that 25 to 30 grams of protein per meal prevent
sarcopenia, a progressive disease where lean muscle mass is reduced by three to
eight percent each decade after the age of 30.

Isn’t Red Meat Harmful?
Red meat consumption
appears to be associated with an increased risk of mortality, according
to a study published in the Archives of Internal Medicine.
However, the study was not
without its critics. It was an observational
study, rather than one with a control group, and the dietary data came from questionnaires
filled out infrequently. Whether a more
rigorous study of the same magnitude and scale would report similar findings
remains to be seen.
Other studies show that red
meat may protect the heart. Thirty-six participants in a 2012 study published in the American Journal of Clinical Nutrition
lowered their “bad” (LDL) cholesterol by 10 percent while eating four to
five-and-a-half ounces of lean beef per day.

Sizzling steaks and hamburgers
aren’t the only meats that help build and maintain muscles.
- Juicy bison burgers are not
only delicious, but healthy as well. In fact, buffalo is high in protein and
lower in fat, cholesterol and sodium than other red meats. The same is true for
emu and ostrich.
- Wild game, including
rabbit, pheasant and venison, is often lower in fat than animals raised for
market, such as ducks and geese.
- Pork is another a great
source of protein. Crispy bacon and pork chops are lower in sodium than ham and
Canadian bacon.
- Lamb is a popular meat
internationally. The leanest cuts include the leg, arm and loin.
- Chicken soup has tremendous
benefits. Your grandma may not have been far off when she recommended chicken
soup as an antidote for the common cold. Both chicken soup and chicken breast
extracts are high
in carnosine, a substance that is
believed to temporarily prevent colds and flus. Soup has other benefits for the
common cold and may help quell symptoms by reducing inflammation.

How Much Protein Do
You Need?
About ten to 35 percent of your daily calories should come
from protein, according
to the Mayo Clinic. If you consume 2000 calories a day, you’ll want to eat
about 50 to 175 grams of protein a day. A three-ounce serving has about 25
grams of protein.
To get more specific, the minimum RDA (Recommended Daily
Allowance) for protein for both adult men and women is .8 grams per kilogram of
body weight. Simply take your body weight in pounds, divide it by 2.2, and
that’s how many grams of protein you need. For example, a 150-pound adult would
need 54 grams of protein a day, or about 6 ounces of lean meat or poultry.
Prevent Muscle Loss
More ways for macho men to stay strong as they age include
these science-based
strategies.
- Perform strength exercises two to three times
per week, working each major muscle group with at least eight to ten
repetitions. Allowing 48 hours between
sessions aids adequate recovery.
- Doing some form of aerobic activity, such as
walking, jogging, swimming or cycling, can also benefit the muscles. Physical
activity promotes heart health as well as muscle health.
Before beginning a new exercise regimen, make sure to
discuss it with your doctor, who can offer individualized guidance.
