9 Nutrition Myths Exposed
By Joe Wilkes
Every fall, the publishing industry begins a new cycle of hitting bookstore shelves with diet books, just in time to help assuage winter holiday guilt and prepare for New Year's resolutions. At the same time, TV stations are in the throes of sweeps periods and launching a new season. You know this is in
full swing when you start hearing the local news and talk show pitches: "You can lose 10 pounds in one week and eat whatever you want!" or "A common
ingredient in your kitchen that will burn off fat without exercise! Tune in at 11 to see what it is!" Then, in the next media cycle, there will be new
books and news stories telling us how the miracle cures were all a load of hooey, but that there are brand-new miracle cures that really work! Here are
some common myths that have gone in and out of fashion over the years and the real truth behind the hype.
- Fat makes you fat. People confuse dietary fat, the fat that we eat, with body fat, the adipose tissue that makes up our spare tires and thunder
thighs. It's true that dietary fat contains twice as many calories per gram as carbohydrates and protein, but what makes us fat isn't the dietary fat,
it's the calories in that fat. In fact, the calories in the carbohydrates and the calories in the protein can also make us fat. Dietary fat is very
important to human health, and should make up around 25 to 30 percent of our caloric intake. For one thing, fat helps with the absorption of several vitamins
that are only fat-soluble, including vitamins A, D, E, and K. Fats also contain heart-healthy omega-3 fatty acids. Artery-clogging saturated fats and
trans fats should be mostly avoided though, as they will raise blood cholesterol levels (see #2) and clog arteries with plaque.
In the 1980s, fats became vilified by regulatory and health agency reports as being unhealthy overall. The reasoning behind this was that while the
agencies were largely targeting saturated fats (as found in animal and dairy products), they believed it would be simpler to tell Americans to avoid
all fats instead of having to explain the complexities of saturated, unsaturated, monounsaturated, polyunsaturated, hydrogenated fats, etc. Because
of these warnings, the food industries began marketing scores of low-fat or fat-free versions of products. In many cases, they would replace the
missing fat with sugar or starch. So while there would be less fat, there would be almost as many calories. Consumers would eat twice as many of
the new "reduced-fat" treats and wonder why they weren't losing any weight.
more studies have come out extolling the benefits of healthy, unsaturated
fats such as those found in olive oil, avocados, nuts, fish, etc., more specific
recommendations have been made to increase the allowance of good dietary fats
while decreasing the allowance of saturated and trans fats. In fact, many
makers of cookies, breakfast cereals, and snack chips now trumpet "No Trans
Fats" on their packaging. That's great, but don't be fooled into thinking
that there are any fewer calories. Just because the manufacturer has shown
restraint in not making the food even unhealthier doesn't mean that it's suddenly
health food. Some of these "No Trans Fats" products never had trans fats to
begin with, but it's good marketing to proclaim it. Now poison free! Not
quite as toxic! Just as fattening with less artery plaque! Check the
labels and make sure that the kind of fat in the product is unsaturated, for
your health—and make sure there aren't too many calories for your waistline.
A day's dietary fat intake should be around 60 to 70 grams.
- Foods with high cholesterol give you high cholesterol. As with dietary fat, foods with high dietary cholesterol levels are believed by many to
raise blood cholesterol levels. High blood cholesterol levels have been linked to heart disease and stroke, and levels should be monitored. However,
our bodies need some cholesterol for normal cellular function and to assist in the production of bile, which helps the body digest fat.
Unfortunately, because dietary and blood cholesterols have been given the same name, people take an attitude of "cholesterol in, cholesterol out."
In fact, studies are increasingly showing that high blood cholesterol comes from a diet high in saturated fats, while foods high in dietary cholesterol
have a fairly negligible effect on high blood cholesterol. Foods high in dietary cholesterol but low in saturated fat such as eggs, shrimp, lobster,
crab, clams, and other shellfish can be safely eaten in moderation without having much effect on blood cholesterol levels. Where this misunderstanding
of the causal link between dietary and blood cholesterol levels may have also come from is that many non-seafood animal products contain high levels of
dietary cholesterol as well as high levels of saturated fat. So if double cheeseburgers are making regular appearances in your diet, you're going to see
a spike in your cholesterol score—but it'll be from the saturated fat.
- Snacking will cause weight gain. Isn't this what Mom always said? "No snacking or you'll ruin your appetite!" Good! Go ahead, ruin your appetite!
If you ruin your appetite, you won't eat so much dinner. Nutrition experts have pretty much come to a consensus that you're much better off having six
small meals over the course of the day than two or three giant meals. You'll give your body a steady source of fuel and keep your blood sugar levels
and metabolism at an even keel all day long. If you think back to our caveman days, before we sat down to eat civilized meals, we probably just
wandered the forests and jungles, eating when we were hungry or when the opportunity arose. Those instincts are worth listening to today. If you
have a hunger pang at three o'clock in the afternoon, don't stifle it because you know you're having dinner at seven. You'll be so hungry, you'll
approach dinner like a Roman orgy, eating way more than you would have if you had merely satisfied your afternoon hunger with a piece of fruit or
a handful of nuts. Keep in mind though, permission to snack isn't permission to stuff your face with Doritos, Fritos, Cheetos, or any other kind
of -tos. There should be some sort of strategy to the snacking. Try evenly pacing out the snacks and predetermine a reasonable portion size of a
healthy food, so you're not just eating handfuls of something out of a bag.
you exercise enough, you can eat whatever you want. How
many times have you heard your horrible friends who never gain weight say,
"Oh, I'll just run it off," to justify whatever sinful treat would give you
a third buttock if you ate it? It's impossible to keep a fit, healthy figure
without both a healthy diet and exercise. It's all right to indulge in the
occasional pig-out sometimes. In fact, it's good to reassure your body there's
no need to go into starvation mode from time to time. But if you eat that
slice of blackout cake, you're looking at a two-hour run just to burn it off,
let alone what came before it. Losing weight and maintaining weight is a simple
equation: if you burn off more calories than you take in, you will lose weight.
Some lucky stiffs have a higher resting metabolism and burn off more calories
naturally, but what probably helps your friend burn off the cake faster is
that they have more muscle on their body, and, even at rest, muscles burn
more calories. So while you can never eat whatever you want and stay thin,
you'll be able to indulge in a pig-out every once in a while if you can keep
your body muscular and lean. And for those times, you might consider trying
exercise designed to burn more calories than walking or running, like Hip
Hop Abs® or Turbo Jam®
Maximum Results, which will help you maximize the calories you burn in
the time you spend exercising.
- Drinking lots of water flushes fat out. Drinking plenty of water is vital for weight loss. If you're dehydrated, your energy and exercise will
suffer. Also, many times we confuse thirst for hunger, so it's always worth trying a glass of H2O before we hit the fridge. Drinking water can even
give your metabolism a slight boost. What it does not do is flush fat from your system. Any excess water that your body doesn't need for proper
hydration and functioning will simply get peed out, and, sadly, it won't be taking any fat with it. You should make sure that you drink enough
water though, but don't go overboard thinking you can chug away your love handles. If you drink too much water at any one time, it could even
result in hyponatremia, or water intoxication. However, adult kidneys can process 15 liters of water a day, so drinking too much water day to day is unlikely (it's more likely if you're involved in extreme Ironman-type athletic activities where over- and under-hydration are real possibilities). Keep a water bottle handy and drink when you're thirsty, but if you really think you can flush
away your beer gut, you might be drinking a bit too much of something else.
Multigrain bread is better than white bread. While whole-grain
bread is better than white bread, multigrain bread is only better if the grains
are whole grains, which isn't always the case. With the bread industry, it's
really important to check the ingredient list carefully. For example, "wheat
bread" is just white bread with molasses added for color. So, if anything,
it's worse for you than white bread. Unless it says "whole-wheat" bread, you're
not getting the added fiber and nutrients that come with using whole grains
as ingredients. Many multigrain breads are just processed-flour breads upon
which manufacturers sprinkled a couple of sunflower and sesame seeds. Hey,
that's two grains, right? That makes it multigrain! So even if the headline
on the packaging says "whole-grain," double-check the ingredient list to make
sure all the grains, or at least the main ones, are whole. Similarly, many
breakfast cereals have switched to whole-grain flour, but if the cereal still
contains more sugar than a candy bar, it's not going to move the needle much
toward better health. Try to find whole-grain brands with minimal or no sweetening.
If you need to, you can always add your own sugar, and at least control the
amount you consume.
causes diabetes. Many people falsely assume that because
diabetics have to watch their sugar and carbohydrate intake that sugar causes
diabetes. But if you don't have diabetes, sugar won't cause you to get it.
The main risk factors for type 2 diabetes are being overweight and being inactive.
As with fat and cholesterol, blood sugar and dietary sugar are often confused.
If you eat sugar, you won't necessarily get diabetes, but sugar is highly
caloric and, as part of a high-calorie diet, can be a contributing factor
to obesity, which does have a causal link to type 2 diabetes. This isn't to
say that it's okay to eat lots of sugar, but it's good to be aware that if
you have a high-calorie diet, you are still just as much at risk for diabetes,
even if that high-calorie diet doesn't include a lot of sugar. As with most
dietary health issues, it's mainly about the calories.
- Grapefruit burns fat. Anyone who remembers the heydays of the Hollywood or Beverly Hills diets knows that they were good times to invest in
grapefruit futures (as well as other "miracle" fruits and vegetables). The theory of those and similar diets was that grapefruit had a secret enzyme
that would make body fat disappear. Grapefruit is a very healthy citrus fruit and worth eating as part of a varied diet. It has tons of vitamin C and
can help fight arterial plaque buildup, and maybe even certain kinds of cancers. But grapefruit can't burn fat. Cabbage soup can't burn fat. Celery
can't burn fat. In fact, no food can. Some foods can temporarily increase your metabolism to assist your exercise efforts in fat loss, but the only
way to truly burn fat is through exercise. And, if any fad diet revolves around a secret fat-burning ingredient, that should be a red flag that the
diet isn't nutritionally sound. Not to sound like a broken record, but the only way to effectively lose weight is to eat fewer calories and burn off
more calories through exercise. Healthy metabolism-boosting foods can help, but they can't do it alone.
- Light olive oil has fewer calories than olive oil. If you read the labels of various olive oils, you'll notice that light olive oil has pretty
much the same amount of calories as any other kind of olive oil. The difference is in the flavor. Light or extra-light olive oil has been heavily
processed to remove the strong flavor of olive oil and make it lighter in color. It might even be combined with other vegetable oils to achieve a
milder taste and color. It still has just as much fat and calories as extra-virgin olive oil, but not nearly as many nutritional benefits, including
vitamin E and polyphenols. Unlike extra-virgin olive oil, light olive oil is an unregulated product, so you don't know what you'll get.

10 Ways to Put Your Appetite on Cruise Control
By Linda York
You may be pleasantly surprised to find out that the strong, sleek, sexy body you are working so hard to build should have a lot more in common
with a Maserati than a Volkswagen. Now, the VW is an excellent automobile. It's cute and perky, and gets great gas mileage. These are all great
attributes for a car. However, we want our bodies to be "gas guzzlers," meaning that we don't want to run all day on a small amount of food or
"gas." We want our engine/metabolism to require more food—the right food—to keep us running fast and lean.
So how do we keep our appetite on cruise control? Here are 10 great tips to keep the calories burning, and your hunger satisfied—a winning
combination for a high-performance body.
- You snooze, you lose. That's right—researchers believe that lack of sleep affects hormones related to appetite, thus causing you to gain
pounds when you don't get enough sleep. People who slept seven to eight hours lost fifty percent more weight than people who only slept five hours.
- Raise another glass. That's water we're talking about. Most of us mistake thirst for hunger. Mark down how much water you drink in a day.
Chances are you will be surprised at how little you drink. Add just two more glasses a day and you'll be amazed at the reduction in your appetite.
Move it and lose it.
You don't just lose calories and weight when you exercise.
Intense exercise changes the way your body craves food and can actually suppress your appetite.
The breakdown that occurs during a hard workout can also raise your appetite but you tend to get
hungry for the types of foods that will repair this damage. One of the best advantages of
is that you are going to start craving "premium" quality fuel—naturally.
- Taste the fruit of knowledge. The mighty apple may have gotten a bad rap in the Garden of Eden, but in the Garden of Eatin', an apple may be
your best friend. Look for a big, delicious, juicy one and take a bite. This fiber-filled food will have you feeling full in no time.
- Soup it up.
Try having a broth-based soup before a meal or as a snack. You can even take your favorite veggie
drink, put it in a coffee cup, nuke it, and enjoy a cup of satisfying soup that will fill you up
and satisfy your desire for something warm, comforting, and yummy. Just beware of major-label soups
as they tend to be high in sodium and use lesser-quality ingredients. As always, it's important to
read the label.
- More is less. In the case of meals, that's the truth. Eat small frequent meals to maintain blood sugar levels and keep your appetite and
energy levels in control and on target for calorie consumption.
Skip rope, not meals. Especially breakfast.
If you don't start the day off with a good breakfast, you wind up
with low blood sugar, low energy, and irresistible hunger pangs, and
the next thing you know, you are running over to a pizza box, your face
is covered in crumbs, and you have severe pepperoni breath. Just remember,
a good meal doesn't mean a traditional meal. Skip the lumberjack special in
favor of a bowl of whole-grain cereal or a protein shake with some fresh fruit
tossed in, Beachbody's Meal Replacement Shake, or leftovers from your healthy dinner the night before.
- Eat your veggies. Yes, your mother was right, but probably for different reasons. Veggies are filled with nutrition, but they will also fill
you up. Try a big luscious salad before a meal in a restaurant (instead of scarfing down the bread). Then have a favorite main dish, though you
will want a lot less of it, and the rest you can take home for lunch or dinner the next day.
- Whole grains rule. You aren't settling for less than what you deserve, and that means complete, healthy, whole grains. Choose the whole-grain
bread, brown rice, and multigrain crackers (see #6 in Joe's article above for more on multigrains) over their anemic white and refined cousins.
- Speed to succeed. You want a speedy metabolism
and high performance when it comes to burning calories, and one of the best
ways to get there is to slow down at the dinner table. That means actually
taking the time to eat your meal. It takes your brain 10 minutes longer than
your stomach to receive the message that you are full. Do an experiment.
Tonight at dinner, find out how long you take to eat your meal. If it takes
you longer to load the dishwasher, then something's wrong with this picture.

Test Your Food Myths IQ!
By Joe Wilkes
True or False?
TRUE: Raw lima beans are poisonous. Lima
beans contain cyanide compounds that can cause illness or even death if eaten uncooked. Cooking turns the cyanide into a harmless gas. Fortunately,
most strains of lima beans available in the U.S. have been bred to contain super-low levels of cyanide. But if you're in another country and you
begin craving raw lima beans, watch out!
FALSE: Swimming too soon after eating causes cramps.
Although it has been repeated so often by paranoid poolside parents that it is presumed to be a medical fact, there is no substantiated evidence
that swimming after eating causes the kinds of cramps that fearful moms and dads purport will cause drowning of the young 'uns. Of course,
cramping is possible with any activity, but having food in your system is unlikely to make a difference.
TRUE: Honey does not spoil. Honey is "cured" by bees to the point that it has a very stable pH level and has an extraordinarily long shelf life. Honey has even been
found in ancient Egyptian tombs, and it's still edible! In part, this is because honey's low moisture content prevents bacterial or fungal
TRUE: Cashew shells are dangerous. You may have
noticed that cashews, unlike peanuts, are never sold in their shells. This is because cashew shells are coated with a naturally occurring oil
which is extremely caustic to human skin. Contact with cashew shells can quickly cause burning and blistering. In fact, the oil is toxic enough
to be included as a common ingredient in insecticides.
FALSE: Swallowed chewing gum takes years to pass through the body. This is another one probably concocted by worried parents who wanted
to discourage their children from swallowing their gum—out of fear that their children would choke. While swallowed gum is a choking
hazard, the notion that habitual gum swallowers are just a gumball or two away from a gruesome pink intestinal blockage is false.
Depending on what the chewing gum is made of, it will either be dissolved by stomach acid or pass out whole through the digestive
