If I want to lose weight, why can't I just diet instead of
exercising?
Answer: If you want to achieve permanent weight loss, most diets
don�t work by themselves. A diet that severely restricts calories is
dangerous for anyone, especially for those with diabetes. Exercise,
combined with your diet plan, helps maintain the weight loss and
strengthens your body.

If I have diabetes, what is the most effective way to lose weight?
Answer: Regular exercise and good nutrition are key to weigh loss.
Regular exercise helps you lose weight by burning calories and increasing
your metabolism. Eating well-balanced meals and controlling your caloric
intake can also further your weight loss efforts.

I always procrastinate when it comes to exercise. How can I get
motivated?
Answer: The first thing you should do is set some realistic goals
for yourself. For example, this might be as simple as walking program in
which you walk around the block for 15 minutes a day. Then you should
gradually build up your program and set new goals in order to stay
motivated.

After lunch I always feel extremely sleepy; yet, I have five more
hours of work left. Can you suggest a lunch meal that will help me stay
alert?
Answer: The drowsiness one experiences after a meal can generally
be attributed to the high levels of serotonin in the brain. High
carbohydrate, low protein meals often generate serotonin levels high
enough to induce a state of relaxation and drowsiness. To avoid "serotonin
snoozing" in the afternoon, it is advisable to eat a relatively light
lunch that contains complex carbohydrates as well as a good protein
source. This would include a tuna, turkey or peanut butter sandwich on
whole grain bread; a garden salad with grilled chicken or fish; brown rice
and tofu; a quesadilla with grilled vegetables, cheese and/or chicken;
cottage cheese with crackers and raw veggies. If a dessert is desired, it
should be in the form of whole fruit such as an apple, kiwi, pear, peach
or plum. Save your higher carbohydrate meal for your evening meal, when
you are in a better position to relax. Or try and

How can I boost my metabolism so that I use more calories?
Answer: Raising your metabolism is done by increasing your
activity level, that is, by incorporating aerobic (long sustained exercise
at a rate that you can comfortable talk) and anaerobic (short burst of
energy exercise) exercise into your schedule. Aerobic exercise should be
done at least 3 times a week for 20 minutes or more. The aerobic exercise
(brisk walking {probably the best all around exercise}, jogging, swimming,
running, bicycle riding, aerobics, cross county skiing, rowing) will boost
your metabolism so that you burn more Calories. Anaerobic workouts with
weights (light weights, nautilus equipment) will increase the muscle mass;
this will also enable you to burn more calories. Muscle use is a major
means of burning calories. Weight routines should not be done on
consecutive days unless you are working different muscle groups. The more
muscle tissue you have on your body, the faster your body burns calories
and the greater your metabolic rate (to a limit). And, contrary to what
some think, muscle does not make you look bulky. In fact, when you put on
muscle (where fat used to be) you will look slimmer. That�s because pound
for pound muscle takes up less room than fat. That also means that you can
actually weigh more, eat more, and wear a smaller pants size!
By eating a low-fat, complex carbohydrate diet, you will be providing
your body with the best fuel for increasing muscle mass, losing excess fat
and increasing your metabolism as a consequence.
But remember, check with your physician first, before starting any new
exercise program!

I love to snack but I am unsure what to eat without eating too much
fat. Do you have any suggestions?
Answer: Some convenient and delicious lowfat snacks include sliced
raw veggies, such as carrots, celery, jicama, red peppers as well as whole
fruits such as apples, oranges, peaches, and grapes. Other options to
consider are graham crackers, bagels, raisins, unsweetened dry cereals,
yogurt and cottage cheese. Not only do these foods provide a wide variety
of flavor and texture in the diet, but these snacks are also convenient to
eat "on the go" and require minimal preparation time. Use the snack foods
in combination to make them more appealing. For example, dip sliced apples
in yogurt or put cottage cheese on your celery. Use your imagination when
planning your snacks and if there is any doubt about the fat content
always refer to the food label.

What are the best foods to eat that will be high in vitamins and
minerals yet low in fat?
Answer: Generally, foods which are low in fat and high in vitamins
and minerals are those which have a plant source rather than a meat
source. Exceptions can be made, however, with meats that have been well-
trimmed of any visible fat and leaner cuts of meat. Seafood can also be a
low-fat source of vitamins and minerals, depending on the variety chosen.
Those varieties from warmer waters tend to have less fat. The white meat
of chicken is a lower fat choice than beef or pork. Although these types
of meat and seafood are lower in fat than others, they are still
relatively higher in fat than foods from a vegetable source, such as
legumes, tofu, breads, pasta (egg provides most fat here), vegetables and
fruits, all of which are good sources of various vitamins and minerals.
Some examples of foods high in Vitamin C include citrus and other
fruits, broccoli, strawberries and tomatoes. Foods high in Vitamin A
include carrots, acorn squash and summer squash. Vitamin E and D are
gotten primarily from cooking oil and milk, respectively and are additives
to these foods. The B-vitamins are found primarily in meat, legumes and
whole grains. Low-fat calcium sources would include low- and non-fat milk,
yogurt and cheeses. Iron is found in dark green leafy vegetables such as
spinach, and kale, as well as in legumes, breads and dried fruit.
Potassium is found in bananas, dried fruits potatoes, beans and low-fat or
non-fat dairy products. Phosphorus is also found in dairy products, as
well as legumes, whole grains and lean meats. Sodium is found in almost
all foods, to some degree, making added salt to the diet unnecessary.
Magnesium is also found in legumes, grains, seafood and brown rice.
If you eat a wide variety of fruits, vegetables and whole grains, and
an adequate amount of dairy and meat products, you should get all the
nutrients you need!

My friend and I love Chinese cuisine but we have heard that MSG is
not good for us. What is MSG and can we continue to eat our favorite
foods?
Answer: MSG is the sodium salt of glutamate. It is comprised of
sodium, water and glutamate. MSG is produced in many countries around the
world through a fermentation process of molasses from sugar cane or beets,
as well as starch and corn sugar. MSG is a widely used flavor enhancer and
additive. Many meats, poultry, seafood, snacks, soups and stews use MSG to
enhance the natural flavors of the dish. Many researchers believe MSG
falls into a separate category of taste, apart from the four basic tastes
of sweet, sour, salty and bitter. This distinctive taste, called "umani,"
in Japanese, is often described as "savory" by Westerners.
MSG is safe for most individuals. And, contrary to popular belief, MSG
is not high in sodium. MSG contains only one-third the amount of sodium as
table salt, sodium chloride (13 % versus 40%). When used in combination
with a small amount of table salt, the flavor-enhancing properties of MSG
allow for less salt to be used during and after cooking. The total amount
of sodium in a recipe can be reduced by 20 to 40 %. Numerous studies have
been done over the years testing the safety of MSG. The FDA continues to
rate it as Generally Recognized as Safe. In 1995, scientific advisors to
the FDA agreed that MSG was safe for everyone. However, some individuals
are sensitive to MSG; therefore, the FDA requires all foods containing MSG
be labeled.

I will be entering menopause soon and I would like more information
about the connection between the use of soy products and estrogen?
Answer: Plant estrogen contains naturally occurring compounds
called phytoestrogens which are found in soy and other whole grains and
legumes in high concentrations. Ongoing studies have been examining the
effects of soy as an alternative to hormone replacement therapy (HRT) to
alleviate menopausal symptoms, lower cholesterol and the reduction of the
incidence of osteoporosis because of the potential side effects.
To date, the epidemiological data show that phytoestrogens relieve
menopausal symptoms similar to the human endogenous estrogen. Research
suggests that the plant estrogens in soy may bind to receptor sites in the
human body in much the same way that the estrogen produced in a woman's
body does. Also, studies show that in reports conducted in Asian
countries, where the consumption of soy products is high, there is a low
incidence of symptoms associated with menopause.
Researchers are studying the relationship of soy to cholesterol. Soy
protein has cholesterol-lowering and anti-artherosclerotic effects. This
has been proven in clinical trials and animal studies. The question is
what component of soy, such as isoflavones or protein, contribute to the
cholesterol reduction. Researchers expect to be able to identify the
component soon.
The loss of ovarian estrogen at menopause is accompanied by an
accelerated rate of bone loss. More studies on the effects of soy on bone
mineral density are being researched actively at this time. In a couple of
years researchers expect to have more information. There is not enough
data to suggest that soy foods can take the place of hormone replacement
therapy, however. More tests are needed and contraindications need to be
ascertained. However, for those women who choose HRT; adding soy foods to
the diet may be a consideration.
Tofu and soy milk, as well as other soy products in your supermarket
are excellent sources of these phytoestrogens. These are also low fat food
sources. Give them a try!

I only eat one meal a day and yet I still can't seem to lose
weight. What am I doing wrong?
Answer: By consuming only one meal a day, you are literally
starving yourself and your body knows it! Many people misunderstand the
concept of losing weight. When you reduce the amount of calories from food
consumption drastically in a short amount of time, your body will
automatically slow down its metabolic rate in order to conserve energy for
survival. Thus, it is useless to starve oneself on such a strenuous diet.
To successfully lose weight, one must change their lifestyle (diet and
exercise) for life!
In regards to eating only one meal a day, try three small meals
instead. This will increase your metabolism, whereas one meal a day will
slow it down. Furthermore, the excess calories from your one meal will
first be converted to glycogen, a fuel your body uses, then the remaining
calories will be converted to fat for storage. The benefits of eating
small frequent meals is that your metabolism will constantly expend energy
due to a "thermo dynamic action" in which your body burns calories as it
processes food you consumed.
With exercise and physical activity, you can also increase your
metabolism - which means you�ll be burning more calories! Begin today, by
walking, jogging, or doing some form of physical activity you enjoy for
1/2 hour a day, three times a week. But, you should get clearance from
your physician before starting a new exercise program.
Also, try to consume a variety of foods. Your body needs vitamins and
minerals from a diverse spectrum of foods in order to function properly.
There is no one food that optimally has all the nutrients you need! On the
average, people consume approximately 1,800-2,200 calories a day depending
on their size, activity level, and their energy needs. If you want to lose
weight safely, try to decrease your calories by 500 Kcal/day. In one week,
you will decrease your total caloric intake by 3,500 Kcals which is equal
to the weight of one pound of fat! It is wise to lose only ½ to 2 pounds a
week, as this will more likely be weight that will stay off.
And last, its important to stay focus and set realistic goals for
yourself. Everytime you reach a goal, reward yourself with a treat. Go out
to the movies, or buy that special outfit you always wanted!

I have recently started an exercise program. What should I eat to
increase my energy during workouts?
Answer: People engaged in regular exercise or sports require a
larger percentage of total calories from carbohydrates than less active
people. This is because the most usable form of energy comes from glucose,
a sugar that is found in the blood and that is primarily supplied by
carbohydrates. Energy can be supplied from simple or complex
carbohydrates. Simple carbohydrates, for example, gives you immediate
energy to sustain you through a 20-30 minute workout of moderate aerobic
intensity. Fruit juice is an example of a simple carbohydrate. If your
exercise program requires that you work out for more than an hour, you
will need more of a slow-burning source of energy such as those supplied
by complex carbohydrates. Good sources of these include whole grain
cereals, breads, or pasta. It is a good idea to avoid exercising on a full
stomach. You should plan to eat your complex carbohydrates an hour or two
before you start your workout. Simple carbohydrates, on the other hand,
may be eaten 20 minutes before you begin your workout. Because these are
only general guidelines, you should experiment to determine what works
best for you. Through trial and error, you will develop a sense of what it
takes to maintain your energy level throughout your exercise program.
Because people who exercise, especially athletes, require extra energy
or kilocalories, they automatically take in extra vitamins and minerals if
they are eating a variety of foods. So, well conditioned athletes who eat
a nutritious diet should have an adequate intake of nutrients. If you are
just beginning an exercise program, and building new tissue, you might
consider a multivitamin/mineral supplement. You should have adequate
protein if you eat a typical American diet. The average American takes in
more than twice the amount of protein that is needed. So, even if you are
building new tissue (muscle) as you begin your program, you should have an
adequate intake of protein. Of all the nutrients, the most important by
far, for the exerciser, is water. Be sure that you are replacing all
fluids that are lost. You can check this by weighing yourself before and
after a workout. Any weight that is lost will be water weight. This weight
needs to be replaced, or you will be at risk of being dehydrated. For
every pound lost, drink 2 cups of fluid (16 ounces). And remember, if you
are just beginning an exercise program, especially if you are over 35
years of age, see a doctor first!

I am confused about butter and margarine. I have heard one has the
"bad" fat and the other contains trans fat. Which one should I use? Please
help, my toast is very dry!
Answer: Most people are confused about what to put on their
morning
Toast: margarine or butter? Here are some facts about the two products:
When you take a liquid oil like corn oil and turn it into a stick of
margarine that can stand upright on your butter dish, a process called
"hydrogenation, or "adding hydrogen," takes place. Not only does this
process increase the amount of saturated fat, but "trans fats" are also
born. Typically the harder or more solid the margarine, the more trans and
saturated fats it has. Trans fats occur naturally in beef, butter, and
milk. However, both saturated fat (found in butter) and trans fats (found
in margarine) have been shown to raise blood cholesterol. Also, there is
much debate over whether the process of hydrogenation can create a
carcinogenic (cancer causing) product.
It may be a good idea to just spread some jam or jelly on your morning
toast if you are concerned about your fat or cholesterol intake. Or, try
fat free or reduced fat cream cheese for a change. You may also want to
try plain yogurt, non-fat or reduced-fat sour cream on your potatoes. Or,
how about salsa? If you do choose to use either margarine or butter, do so
in moderation. Just using half as much as you normally would will make a
difference.

Lately, life has been so hectic that dinner meals for my family
have been varied only by the fast food restaurants on the way home from
work. What can I do to make my family meals healthier and easy?
Answer: Family lifestyles today can be very hectic because there
are so many opportunities available and we try to take advantage of them.
The same holds true when selecting and preparing meals for our family.
Because time is often limited, meal patterns need to be adjusted to fit
this kind of lifestyle. There are many ways to remedy this problem.
By preparing meals ahead of time and freezing them, this can save time
while providing good nutrition for the family. Frozen meals can be
defrosted and re-heated in the microwave in a matter of minutes. They can
also remain in the freezer for about three months.
There are a number of magazines, websites, and recipe books available
for preparing quick nutritious meals. Cooking Light (a magazine) offers
quick easy meals that are low in fat. There are various websites on the
internet you can browse through to find easy recipes (Keyword: cookbook).
There are countless cookbooks on the market for quick easy recipes,
microwave cookery, stir fry meals, and grilled foods. The American Heart
Association has a good cookbook for low-fat cooking.
When choosing a fast food restaurant for a quick meal, there are some
good choices to consider. Consumer reports showed that grilled chicken
sandwiches, roast beef sandwiches, and salads with low-fat dressing are
the best choices nutritionally. And, if you have to have a burger, the
least expensive hamburger usually has the lowest fat and calories. This
burger with a diet soda is an OK occasional choice. Then, supplement with
fresh fruit and vegetables. But, you need to have these on hand.
Pre-peeled carrots, apples and bananas are easy to grab and eat. When
comparing the lower fat entrees at fast food establishments, the lowest in
fat were Wendys grilled chicken, Arbys light roast beef or turkey deluxe
sandwiches. There are several homestyle restaurants that offer nutritional
meals. Among them are Boston Market, Kenny Rogers Roaster, and Koo Koo Roo.
These offer homestyle nutritious meals at an affordable cost.
These are just some meal alternatives for a hectic family lifestyle. By
planning ahead, taking advantage of technology and just being aware of
what�s available, you won�t have to feel guilty about dinner meals. And
remember, you can now buy pre-cut salads, pre-peeled carrots, low fat
entrees, and many other nutritious items that are easy to prepare!

I really don't like vegetables. Where else can I get my vitamins
and minerals?
Answer: If you don't like vegetables, there are many other food
sources which provide substantial amounts of vitamins and minerals.
Following, is a list of vitamins and minerals in accordance to its food
sources (other than vegetables), ranked from highest to lowest amounts.
Keep in mind however that vegetables offer powerful antioxidants that can
help keep our bodies healthy and it is important that you try to include
them in your daily diet!

particularly wheat
Vitamins and minerals are found in a diverse spectrum of foods. That is
the very reason, people should consume a variety of foods: breads (6-11
servings), meats (2-3 servings), fruits (2-4 servings), dairy (2-3
servings), and even vegetables (3-5 servings) on a daily basis. Vegetables
are especially important in our diet because it provides not only
plentiful amounts of vitamins and minerals, but also antioxidants and
fiber which may not be found in other food sources.
Therefore, it is important to eat a variety of foods in order to obtain
optimal health.

I want to be as healthy as possible, so what should I be eating?
Answer: With all the diet myths and health related products on the
market, healthy eating can be confusing and complicated. Healthy eating
simply means balance, moderation, and variety. Balance each meal with
foods from different food groups. Avoid large or small meals. Remember
that moderation is the key in weight control. Healthy eating is not boring
or bland if a wide range of various foods are introduced. Limit fat intake
to less than 30% of total kilocalories per day, saturated fats to less
than 10%, polyunsaturated fats to less than 10%, and monounsaturated fats
to 10% of total kilocalories. Here are some suggestions to cut down on fat
intake:
Trim visible meat fats before cooking.
Most of the poultry fats are on the skin, removing the skin can cut a
third to half of the total fats.
Skip the egg yolks since it is high in fat and cholesterol. Try egg
whites or egg substitutes (available in supermarkets) to replace a whole
egg.
There is nothing killing to a healthy salad than a high fat dressing.
Try low fat versions of dressing, flavored vinaigrettes or yoqurts. Since
restaurants tend to overdress the salads, ask for dressings on the side.
Cut down on saturated fats such as butter, lard, yolks, and meat
drippings. Fruit puree is an excellent substitutes for butter and
margarine in baking. Use vegetable oils instead of in frying.
Breakfast is an excellent way to start off a healthy day. Try a low fat
peanut butter and strawberry jam sandwich, toasted English muffin with 1%
cottage cheese, cereals with skim milk, or a simple fruit milk shake.
Remember, balancing diets with a wide variety of foods is the key to
healthy eating

Dinner for me is around 7:30 p.m. and I have heard that eating late
at night makes you fat. Is this true? What is the best time to eat?
Answer: The time of day that meals or snacks are eaten can affect
ones weight to a relative degree. However, the foundation of weight
maintenance is a matter of energy balance--eat too many calories or burn
too few calories and voila!--excess fat is gained.
Each of us requires a certain number of calories each day to maintain
our basic bodily functions and to perform daily living activities--our
metabolism. We also utilize calories via a mechanism known as the Thermic
Effect of Food (TEF), whereby our bodies burn calories just to digest the
foods we eat. Some studies suggest that our TEF is greater earlier in the
day and wanes as the day advances. Thus foods eaten later in the day may
not induce the greatest thermic effect. However, our TEF accounts for only
about 10% of our overall metabolic processes.
The most effective method to achieve a healthy weight is to consume
three to six meals, spaced as evenly as possible throughout the day.
Skipping meals, and then consuming the majority of calories at one meal,
can cause changes in metabolism leading to weight gain, whether that meal
is eaten during the morning, noon or night. The overall composition of the
food eaten should represent no more than 30% of calories from dietary fat,
20% of calories from protein sources, with the remainder to be obtained
from complex carbohydrates--all to be consumed in moderate amounts within
the framework of our daily caloric needs. When we exceed this limit we
gain fat, and when we remain within this boundary we maintain our optimum
weight.

I take a psylluim fiber drink each morning with my iron supplement
and my multivitamin/mineral supplement. Is this ok? What would you
suggest?
Answer: If you are getting all the servings you need from each of
the five food groups every day, you probably don't need a supplement.
Consuming a wide variety of foods provides you with the different types of
nutrients. Supplements may only be helpful when you are not consuming an
appropriate number of servings from MY Pyramid, if you are on a
low-calorie weight loss diet, or are pregnant or lactating. The best
recommendation to get your adequate intake of fiber, iron and your other
vitamins and minerals each day is to consume a variety of healthy and
nutrient rich foods. If you choose to take supplements, taking fiber and
iron together is a good idea because fiber can aid in the absorption of
certain minerals such as iron. Taking a vitamin supplement at the same
time is acceptable as long as the supplement does not also contain
calcium. Taking iron and calcium at the same time will cause less of the
calcium to be absorbed in the intestine, because the two minerals compete
with one another for absorption. If your vitamin supplement includes
calcium, it would be good to take your fiber and iron in the morning and
your vitamin supplement at night. To determine the number of servings that
you need visit the My Pyramid website!
