1. Food
Intake – How much do you need?
First of
all, you need to understand that in order to begin losing weight you must
consume fewer calories than your body burns in a period of a day. The bottom
line is, regardless of the confusion brought on by the media and industry,
calories still count!
Your body
weight is largely a product of total daily caloric intake minus total daily
energy expenditure (TDEE). So, to lose weight, your daily food consumption
measured in calories must be less than TDEE. In other words a deficit in
calories must be created to trigger a reduction in body weight. Although this
is a simple concept, it’s not easily accomplished. And statistics prove it:
approximately 50% of Americans are obese and two thirds of Americans are
borderline obese.
It doesn’t
have to be that way, however. People need to be educated with respect to
health, nutrition and weight loss maintenance. Knowledge is what we need.
Knowledge is power, and with power comes change.
One simple
guideline for losing weight is to adjust your daily caloric intake to equal ten
times your weight in pounds. For example if you weigh 180 lbs. your total daily
food intake should equal 1800 calories. This would create a sufficient deficit in
calories for gradual weight loss. This method will not work, however, for
people who are extremely obese.
Another
efficient method of losing weight at a reasonably comfortable pace (for any
person) is to reduce your total daily food intake by 500 calories. One pound
equals 3500 calories and at the rate of 500 calories per day, it translates to
1 pound of weight loss per week. This is a sensible, realistic weight loss pace
and more likely to succeed in the long term. On the other hand, diet programs
based on more extreme calorie restriction are very stressful physically and
mentally, which is why they result in quick but temporary weight reduction. Not
to mention the high cost of many weight loss plans that include pre packaged
food, unnecessary meal replacements, supplements and so on.
A more
accurate method to figure out how many calories you actually need (to maintain
your weight) is to take your body weight and multiply it by 11. Say you weigh
160 pounds and you are completely sedentary.
160 x 11 =
1760 (calories). So you would need 1760 calories if you sat around all day with
very minimal movement to remain at 160 pounds.
Now to go a
step further, we have to determine your metabolic factor. There are 3 main
categories for metabolism. Slow metabolism is when you have a very difficult
time losing weight. Medium metabolism means you don’t have difficulty losing
weight - if you really try. And Fast metabolism is when it seems no matter how
much you eat you can’t gain weight. Don’t I wish I had that problem. See the
table below.
Slow
Metabolism (%)
Under 30
Years of Age - 30%
Between 30-40 Years of Age - 25%
Over 40 Years of Age - 20%
Between 30-40 Years of Age - 25%
Over 40 Years of Age - 20%
Medium
Metabolism (%)
Under 30
Years of Age - 40%
Between 30-40 Years of Age - 35%
Over 40 Years of Age - 30%
Between 30-40 Years of Age - 35%
Over 40 Years of Age - 30%
Fast
Metabolism (%)
Under 30
Years of Age - 50%
Between 30-40 Years of Age – 45%
Over 40 Years of Age - 40%
Between 30-40 Years of Age – 45%
Over 40 Years of Age - 40%
Let’s
continue with the above example (1760 cal.) and let’s say you’re 35 years old
and have a slow metabolism. The corresponding metabolic rate factor would be
25%. 1760 x 25% = 440 calories – which means you would need an additional 440
calories. Your total daily calories would therefore equal 2200 (1760 + 440). In
other words, you would require 2200 calories per day to maintain your present
weight.
Now to lose
weight at a comfortable pace (as mentioned above), subtract 500 calories from
this total.
That would equal 1700 calories (2200 – 500). Consequently, in order
to lose one pound per week you would require 1700 daily calories from food. The
next step would be to keep track of all your calories. To do that you will need
to know the calorie content of the foods you eat. A calorie counter or
calculator is where you enter the type of food product, the amount (in grams or
ounces) and it calculates the calorie content for you.
You can find them at
many websites online for free. One that I found to work fairly well, which also
contains a huge selection of foods including items from fast food restaurant
chains, is at http://www.caloriesperhour.com/
To increase
your rate of weight loss even further you can raise your exercise level. One
way to accomplish this is by participating in a program of regular physical
activity or if you already are, simply increase the exercise intensity level.
See tip number 6 and 7 in this article for more information on physical
activity and weight loss.
2. Diet
Composition
Your diet
must consist of foods from all food groups (e.g. meat, dairy, vegetables,
fruits, whole grains, nuts/seeds, legumes). If you’re a vegetarian, you can
still get sufficient amounts of protein from legumes, soy bean products and
whole grains. In a French study, evidence suggested that diet variety was one
of the reasons French people were less obese and had fewer occurrences of heart
disease than Americans.
Another important factor was the diversity in their
diet. Overall, the French diet contained more foods from all food groups and
consisted of more types of food and food products compared to the American
diet. (1)
Furthermore,
the French seemed to enjoy their food more. Their meals were like special
gatherings, celebrations, meant to be enjoyed by all. They typically didn’t eat
very fast. They seemed to enjoy their food more; it’s as if time stood still
during their meals. This method of eating accomplishes several things.
For one,
eating slower and being more relaxed during meals increases chewing time. In
addition, by slowing down the pace of a meal and chewing more, you are more
likely to get a feeling of fullness while eating less quantities of food. In
contrast, North Americans, very often eat on the run.
The other
benefit of the French eating style is that it aids the digestive process by
reducing workload and improving the efficiency of nutrient distribution
throughout the body. An increase in food variety and diversity decreases the
percentage of bad foods (saturated/trans fats, unrefined carbohydrates) present
in your digestive system. Moreover, increased fiber content from fresh foods
(fruits vegetables and whole grains) also sweeps up and pushes out bad foods
quicker, leaving them less time to be absorbed by the intestines and therefore
becoming less harmful. As a result risks of developing chronic diseases, such
as various forms of cancer and heart related diseases are also reduced. (2)
3. Quantity
and Frequency of Meals
Does the
size and quantity of your meals really matter? You’ve probably heard many times
over that it’s best to have smaller more frequent meals throughout the day. In
other words snacking is preferable to gorging. Is this fact or fiction? Well,
the fact of the matter is that scientific research with respect to this area of
study has been largely contradicting. There really is no overwhelming evidence
to support the idea that increased frequency and decreased portion size of
meals is associated with weight loss efficiency. This eating method, however,
has been shown to benefit athletic performance in trained athletes. (3)
pond with
periods of physical demand associated with training, help to maximize
performance. Keep in mind that improving athletic performance in athletes is
one thing, but increasing the rate of weight loss is something quite different.
Although, when taken to extremes, it is probably better to eat 8-10 smaller
meals per day than 1 large one for example.
As it turns
out, the customary three meals a day method is just fine. There just hasn’t
been enough convincing evidence to prove that it has a negative effect on
weight loss. Eating 5-6 meals a day is also fine. Changing to a more frequent
eating style, however, may cause you to over eat, if you’re not careful,
especially at the beginning. This is because, subconsciously, you’re used to
having larger food portions at meal time. So, it’s important to keep track of
the food quantity of every meal, until you get accustomed to the new way of
eating.
4. Don’t
Skip Meals
Ever heard
that breakfast is the most important meal of the day? Well it’s true. The one
meal you should never skip is breakfast. It is the meal that sets the tone for
your metabolism. When you miss breakfast your metabolism responds by slowing
down. Your body receives signals of famine from the brain and switches to energy
conservation mode. This means rather than burning calories the body gets
stingier with them.
The other
thing that happens, when missing breakfast is, by the time lunch time comes
around you feel starved and you almost always end up overeating. And as a result
of this added pressure on your digestive system, most of your energy gets used
up as your body works hard to digest and absorb all that food. Needles to say,
you won’t feel very productive when you return to work, a feeling which may
last for the next few hours.
Another
important benefit of not skipping meals is that your blood sugar level is more
stable, which keeps insulin in check – reducing unnecessary fat storage and
ensuring that you have adequate energy levels required to perform your daily tasks
with less physical and psychological stress.
5. Water
It was
thought that drinking plenty of water throughout the day was a crucial part of
a good weight loss strategy; the theory was that an adequate amount of water –
8 eight-ounce glasses per day – gives you a feeling of fullness which reduces
periods of hunger; and the less you feel hungry the less you are going to snack
– which translates to fewer calories. Recent studies have suggested, however,
that choosing foods with high water content like fruits and vegetables and
blending water into meals like soup has a greater effect on satiety, than
simply just drinking water. And that it may result in a reduction of total
daily calories.
In other
words, including water rich foods like watermelon and other fruits and
vegetables, fruit juice, and soups in your diet, is more effective with respect
to satiety than relying on just drinking water. As a result, you wouldn’t need
to drink 8 glasses of water a day, if you were getting an adequate supply from
your diet. In fact, drinking 8 glasses of water per day is a misconception.
This number was originally reported by the National Academy of Sciences of the
United States Food and Nutrition Board. They also mentioned, however, in the
same report, that the majority of water people need comes from food. (4)
The
recommendation for a healthy individual is to drink one cup of water or juice
with every meal. (ibid)
It’s also
important to keep in mind that the human body is made up of 60-70% water. All
our organs consist of a lot of water. Blood is mainly composed of water. So it
makes sense to ensure that you’re always getting an adequate supply. Here are
some functions of water:
- regulates
your body temperature
- transports nutrients to your organs
- transports vital oxygen to your cells
- removes waste from your body
- protects all your organs and joints
- transports nutrients to your organs
- transports vital oxygen to your cells
- removes waste from your body
- protects all your organs and joints
6. Exercise
As you know,
exercise participation is an important factor in weight loss and weight loss
maintenance. In addition to weight reduction here are 20 important health
benefits of physical activity.
1. Increases
thermogenesis (increase in body temperature to burn calories).
2. Raises
basal metabolic rate increasing calorie expenditure even during periods of rest
or sleep.
3. Releases
natural stimulants in the body helping to improve overall psychological
condition. In other words it may alter your mood to a more positive state. (5)
4. Relieves
stress and reduces the risk of stress related chronic diseases. (ibid)
5. Improves
sex function
6. Lowers
High Blood pressure levels.
7. May
increase levels of good cholesterol (HDL)
8. Lowers
elevated blood cholesterol levels.
9. Improves
blood circulation.
10.
Increases the level of oxygen uptake (VO2 max) and improves endurance. Vo2 max
varies directly with the level of physical fitness.
11.
Increases lean body mass (muscle) while reducing body fat - improving body
composition and therefore improving physical appearance.
12. Improves
self esteem.
13. Causes a
natural tendency to be more conscious about eating healthier and therefore may
improve a person’s diet.
14.
Strengthens the musculoskeletal system protecting the body from unexpected
physical shock.
15.
Strengthens the body’s immune system and therefore slows down the aging
process.
16.
Strengthens bones and fights against osteoporosis - especially important for
post – menopausal women. (6)
17.
Strengthens the body’s immune system and therefore slows down the aging
process.
18. Helps to
fight against chronic diseases including many forms of cancers and heart
disease. (7) (8)
19. When
combined with stretching it may help to reduce lower back pain.
20. Improves
physical condition in pregnant women making it easier to cope with the trials
of childbirth: It increases energy levels; helps to reduce back pain; improves
circulation and reduces swelling and development of varicose veins; tones
muscles making it easier for the body to return to pre-pregnancy condition. You
should check with your doctor, however, before you begin exercising during
pregnancy. (9)
How Much
exercise is Necessary for Weight Loss?
It depends
on your goals and your body condition. Here are some questions you should ask
yourself:
- How much
weight do you want to lose?
- What’s Your Age
- How much do you weigh?
- What is your physical condition?
- What is your daily caloric intake?
- Will you combine exercise with caloric restriction?
- What’s Your Age
- How much do you weigh?
- What is your physical condition?
- What is your daily caloric intake?
- Will you combine exercise with caloric restriction?
If you’re
overweight, by more than 20 pounds, you need to participate in a program that
includes diet restriction (reduce total daily calories by 500 cal.) and regular
exercise (6-7 days a week). You should exercise for at least 30 continuous
minutes – for best results increase the duration (up to 60 minutes). Your
target intensity should be between 65-75% of your maximum heart rate – in other
words, a comfortably vigorous level of intensity. The American College of
Sports Medicine recommends that a good weight loss program should consist of
daily caloric expenditure of 300-500 calories from exercise. (10)
How do you
calculate your heart rate? An easy formula for figuring out your maximum heart
rate works by simply subtracting your age from 220. If you’re 40 years old, for
example, your maximum heart rate is 180 beats per minute (220-40). To train at
70% of your maximum heart rate, simply multiply 180 by 70 and divide by 100,
which equals 126 beats per minute. Therefore in order to train at an intensity
level of 70% of maximum heart rate your training heart rate should be 126 beats
per minute. How do you calculate your heart rate during exercise? Simply take
your pulse by counting the number of beats over a 10 second period. Multiply
that figure by 6 and you have the number of beats for a 1 minute period –
that’s your training heart rate. Before you begin exercising, however, get
clearance from your doctor, especially if you’re a beginner.
7. Exercise
for Weight Loss Maintenance
Once you
reach a desirable body weight, you can switch your exercise routine to weight
loss maintenance mode. That means you can reduce the frequency of your workouts
to 3-4 times a week. The duration and the intensity should remain the same - 60
minutes at a comfortably vigorous level. You will notice as you reach higher
levels of fitness, exercise intensity must be turned up a notch to keep the
workout challenging and also to burn more calories.
What types
of activities should you participate in? There are many forms of exercise that
are efficient in producing adequate weight loss and fitness. Some of them
include aerobics, step or boxing aerobics, cycling, spinning, step-climbing,
training on elliptical machines, cross country skiing (real or machine
version), in line skating, ice skating, swimming, jogging, skate boarding, and
sports like basketball, hockey, and soccer. There are many more. The important
thing is to choose one that you’ll really enjoy. This way, your chances of
sticking with it in the long run will be much higher.
Have fun,
get in shape, lose those extra pounds and keep them off!
