If you look at many different weight loss experts, they all
seem to fall within one of two camps. The first claims that it is possible to
achieve weight loss through diet alone. The other camp claims just the
opposite- that training alone is enough to achieve weight loss. For someone who
is trying to decide what route they want to take it can be difficult to figure
out which claims are true in order to achieve the weight loss results they are
looking for.
There is a third camp that states that diet and training are
both necessary, not only for weight loss but also to maintain a lifestyle that
is much healthier than either extreme by itself would be. Unfortunately, many
people do not understand how diet and exercise go hand in hand in order to
maximize good health. Here is what they need to know.
How We Gain And Lose Weight
Our bodies are made to store excess energy in the form of
fat. We take in food energy, in the form of calories, with the foods that we
eat. Everything we do, from walking to breathing to typing on a computer, uses
up energy. If we take in more energy than we burn off during the day we will end
up gaining weight. If that trend is reversed, and we begin to take in fewer
calories than we use in a day, our weight will drop.
We can reduce our caloric intake by:
Choosing foods that have fewer calories
Reducing portion size
Eating a larger number of small meals and snacks throughout
the day to keep up our metabolic rate
Choosing foods that have less fat in them. Fat is a prime
source of calories and can also cause a range of other health problems
depending on the amount and type of fat that is being consumed
We can increase the amount of exercise we get by:
Choosing to walk rather than drive a car
Taking stairs instead of an elevator or escalator
Finding ways to take part in activities that are not
sedentary
The rate at which our bodies use the energy we take in is
called the metabolic rate. When we are active, our metabolic rate increases so
that we are able to burn energy more quickly. It continues to be elevated for
some time after the activity is finished. As well, when we eat, for a short
time after we take in food, our metabolic rate is also elevated. By eating
several small meals and working periods of exercise into our daily routine we
will be able to have a higher overall metabolic rate. This means that we will
burn more calories and this, ultimately, can help us lose weight.
What Studies Have Shown About Diet vs. Training
The question of diet vs. training is a popular one for many
researchers. There are a number of reasons for this. One is that the details of
the studies being done are easy to set up. It is possible to simply have one
test group undergo training but maintain their regular diet. The second group
can simply limit the calories or other dietary components and monitor how much
weight is lost without performing any additional exercise.
These studies are also popular because they attract a lot of
attention. People are always looking for a way to maximize their weight loss
with as little effort as possible. Here are the results of several of these
studies:
A University of Manitoba study concluded that dietary
changes did indeed produce better results than a change in the amount or type
of exercise being performed. Specifically, the study showed that a sharp
reduction in the amount of dietary fat being consumed led to more substantial weight
loss. It also showed that without dietary changes it may be impossible for a
woman to achieve significant weight loss through exercise alone
In an article published in 2000, researchers R. Ross, J.A.
Freeman and I. Janssen stated that the findings of the American College of
Sports Medicine were incorrect. These findings stated that without caloric
reduction and dietary changes, exercise alone was not enough to cause
significant fat loss. However, the article that was published by these
researchers stated that there were randomly controlled styles that supported
findings opposite to those of the ACSM. The feeling was that the factors had
not been made equal and if this did occur, that exercise would be just as
effective as dietary changes for losing weight
The Cochrane Collaboration which was made up of
approximately 12,000 scientific researchers and experts found that exercise
without dietary changes did not result in massive weight loss. However, it did
have a beneficial impact on other areas of health such as cholesterol levels
and blood pressure levels. This suggested that it would have an excellent
impact on health in general
How To Improve Your Health Most Effectively
Although many of the studies have shown that exercise alone
is not enough to burn fat and lose weight, they have also shown that to
maximize weight loss there needs to be a combination of exercise and a balanced
diet. By reducing calories and choosing foods that are high in nutrients and
low in fat and calories we can improve our health.
By choosing foods that are high in fat and calories we can
do a lot more damage to our bodies than an expanding waistline may let on. A
diet that is high in fat and calories can cause the following issues:
High amounts of bad cholesterol and low amounts of good
cholesterol
Cardiovascular issues such as clogged arteries and high
blood pressure that can lead to a heart attack or stroke
Diabetes
Any one of these conditions can ultimately be fatal. Even if
they are not, they can lead to other problems that may cause you to become
handicapped or shorten your life by a substantial amount.
Some suggestions on ways to improve your diet include:
Eating a variety of fruits and vegetables of different colors.
This is because they will vary in their nutritional content and variety will
allow you to get the full benefit of antioxidants, vitamins and minerals
Choose to cook foods in ways that limit the use of fat. This
includes steaming, sautéing, roasting and boiling instead of frying
Reducing the amount of red meat that is eaten. Choosing
leaner cuts for the red meat that you do still eat
Alternating protein from animal sources with protein from
plant sources such as beans, tofu and tempeh
Choosing protein sources such as chicken, turkey, and lean
cuts of pork, lamb and veal
Using olive oil rather than butter or other sources of
saturated fats. Olive oil is high in omega 3 fatty acids and other beneficial
compounds that can help improve cardiovascular health
By choosing to increase the amount of training that you are
doing you will find that you will be able to lose weight as quickly and safely
as possible. In the end, a combination of both approaches will help you lose
weight much more rapidly than either one would by themselves.
