The only way your body can store energy from food is in the form of body fat.
False emoticon
Your body can store energy from food for future use in two ways: 1) as fat and 2) as muscle fuel (called glycogen). Its first priority is to fill its glycogen tanks, because glycogen is the body's primary source of energy for physical activity. Once your glycogen stores are filled and the rest of the body's energy needs are covered, all the extra energy from your food will be stored as body fat.

If you feel thirsty, you could already be dehydrated.
True emoticon
The first signs of dehydration include thirst, dry lips and tongue, fatigue, lack of energy, and feeling overheated. If you wait to drink water until you "feel" thirsty, especially on hot days or during workouts, dehydration has already started.

Residents of developed countries (like the U.S.) are more likely to experience allergies than people in developing areas of the world.
True emoticon
Generally speaking, developed countries have much higher incidences of allergies than developing areas of the world. Scientists believe that the clean and sanitized homes of the industrialized world are actually detrimental to the immune system, and that exposure to illness-causing bacteria is necessary for the immune system to function optimally. When your immune system is not challenged by natural foes, it malfunctions and becomes supersensitive to seemingly harmless substances.

Which of the following supplements can help prevent colds and the flu?
None of the above emoticon
Although each of these substances have been linked to cold prevention in some studies, but the jury's still out on the best role for herbal and vitamin supplements. According to respected organizations (such as the National Institutes of Health and the National Lung Association), there is no conclusive evidence that supports the notion that taking large doses of vitamin C, zinc, or Echinacea will prevent colds. However, these nutrients may reduce the severity or duration of some symptoms. Always talk to your doctor before taking any supplements.

How accurate are 'skinfold' body fat tests that use callipers?
98% emoticon
The American College of Sports Medicine states that skinfold measurements, when performed by a trained, skilled tester, are up to 98% accurate. Because of the consistency in results, the high success rate, and the low margin of error, this is generally accepted as the best field test, outside of clinical testing, such as hydrostatic weighing.

Which of the following statements about alcohol's effects on blood sugar is correct.
It can both raise and lower blood sugar emoticon
Alcohol can interfere with your blood glucose control, both raising and lowering blood sugar. Once in your system, alcohol initially lowers blood sugar, which can lead to hypoglycemia (low blood sugar). Some alcoholic beverages can raise your blood sugar because of their high carbohydrate content. To prevent your blood sugar from going too high, avoid sweet wines, liqueurs, and sweetened drinks like daiquiris, margaritas, pina coladas, etc. and choose lower-carb drinks

To build greater muscle strength, you should do ___ repetitions of each exercise? Both A & D emoticon
If your goal is to build strength and muscle size, then aim for fewer reps (such as 8-10). Because you are doing fewer reps, you will need a heavier weight to reach muscle exhaustion in each set, so that's where the phrase "heavy weight, low reps" come from.

According to the glycemic index, people should eat more foods that have...
A low glycemic index emoticon
One system for classifying carbohydrates is the glycemic index. The glycemic index ranks foods on how they affect blood sugar level by measuring how much the blood sugar increases after one eats. For example, white bread is digested quickly into glucose, causing blood sugar to spike quickly. Therefore white bread has a high glycemic index number. In contrast, brown rice is digested more slowly, causing a lower, more gentle change in blood sugar. It therefore has a lower glycemic index number.

Too much iron can be toxic.
True emoticon
Iron can build up to dangerously high levels in the body, especially in people with the genetic problem called hemochromatosis. Over supplementation of iron can also occur. This is especially dangerous in children who may take adult vitamin/mineral supplements. Immediate medical attention should be obtained. The Tolerable Upper Intake Level is 45 milligrams daily for both adult males and females.

You pack a lunch that contains a turkey and cheese sandwich. How soon must you put your lunch in the refrigerator so that it remains safe to eat?

If you pack a lunch that includes perishable food items--meat and cheese sandwiches, leftovers, salads, or dairy foods--don't let more than two hours pass from the time you make your lunch at home to the time you put it in the office refrigerator. The same rule applies if you go out for lunch and bring back fast food, carry out, or doggy bag.

Antibiotics can treat a cold or the flu.
False emoticon
When you come down with a cold or the flu, the last thing you should do is take an antibiotic. Most antibiotics only work against infections caused by bacteria, so they won't work against illnesses (like the cold or the flu) that are caused by viruses. Currently, no licensed antibiotics exist for fighting the common cold. Some prescription antibiotics (known as antiviral medications) are available and effective against the flu, but only if they're taken very early in the illness.

The elderly are more likely to be depressed than any other age group.
False emoticon
Depression is not a natural part of aging. While you may think that the risk of developing depression increases with age, that's not always the case. In fact, studies show that the elderly are more likely to be happy and content with their lives than their younger counterparts. Depression can occur at any age (even in children), but it is most common in people between the ages of 24 and 44.

Walking alone might not be enough to prevent weight gain.

Exercising on an empty stomach, such as first thing in the morning, will help your body burn more fat.
False emoticon
In the morning, your body has gone 8+ hours since eating or drinking anything. Your blood sugar levels are lower at this point, and your body doesn't have adequate fuel to workout optimally. Usually, experts recommend eating something—even if it's just a small snack—within 2 hours before working out. When your body doesn’t have proper fuel in it, many problems can result, the lesser being that your workout performance suffers, and the greater being something like passing out during exercise. Some people say that it will burn fat stores, but overall, the number of calories your burn during a workout (regardless of where they come from) is much more important. Plus, fat burns in the carbohydrate flame. This means if you exercise without eating (such as after "fasting" during sleep) your body does not burn fat efficiently, or sometimes at all.

With each step you take, how much force do your knees and hips experience? 2-4 times your body weight emoticon
Every time you take a step, the force on your knees and hips equals two to three times your body weight! Climbing down steps will increase the pressure on your knees and hips by six-fold—that's 900 pounds of pressure for a person who weights just 150 pounds. Your risk of developing osteoarthritis generally increases with the amount of weight that your joints have to bear. Once osteoarthritis has developed, being overweight exacerbates the condition. Your SparkDiet can help you lose the extra pounds safely and permanently.

After an intense workout, what nutrient does your body need most?
Carbohydrates emoticon
Carbohydrates. Roughly 60% of the calories you eat at this time should come from carbohydrates. Contrary to popular belief, your body needs more carbohydrates than protein after a workout, to replace the muscle fuel (glycogen) you used up and to prepare for your next exercise session. Moderate exercisers need about 30-40 grams of carbohydrates after an hour of exercise, but high-intensity exercisers need more; around 50-60 grams for each hour they exercised

Bad form is never a good idea. The only thing this will accomplish is increasing your risk of injury. Your goal should be to stop after the last repetition you can do in good form--that means without using momentum or body contortions to move the weight.

The ''Freshman 15'' is a myth.
True emoticon
A 2011 study published in Social Science Quarterly showed that the typical weight gain during the first year of college is just 2.5 to 3.5 pounds and has little to do with higher learning and more to do with becoming a young adult. The not so good news: About 10 percent of freshmen will gain 15 pounds or more during their first year. And that's just the first year. Experts aren't as concerned about these actual pounds as they are about the rate at which students put them on. A 2008 study found that college students gain weight six times faster than the general population. And according to researchers, young adults continue to gain weight (1.5 pounds per year on average) during the four years after they graduate, too. Not all of this can be chalked up to "growing up," though. If left unchecked, the weight gain many experience as young adults can become a serious problem.

It's important to maintain a regular sleep and wake schedule each day, including weekends.
True emoticon emoticon
Your sleep-wake cycle is regulated by a "circadian clock" in your brain and the body's need to balance both sleep time and wake time. A regular waking time in the morning strengthens the circadian function and can help with sleep onset at night. That is also why it is important to keep a regular bedtime and wake time, even on the weekends when there is the temptation to sleep in.

In Tabata training, what percentage of your maximum heart rate should you shoot for to reap the most physical benefits?
75% emoticon
While you don't have to have a heart rate monitor to do a Tabata-training workout, it certainly can come in handy. "Maximum effort" is by definition about 90%-95% of your maximum heart rate (calculate your max heart rate here), but working out this hard is generally reserved for only advanced exercisers and athletes. For Tabata training workouts, aim for 75% or more of your maximum heart rate to reap the most benefit.

Difficulty falling asleep is just one of four symptoms generally associated with insomnia. The others include: waking up too early and not being able to fall back asleep, frequent awakenings, and waking up feeling tired. Insomnia can be a symptom of a sleep disorder or other medical problem, and can often be treated. If insomnia symptoms occur more than a few times a week and also impact your daytime functions, discuss these symptoms with your health care provider.

___ is the painful sensation or state of weakness caused by the need of food. Hunger emoticon
By definition, hunger is "the painful sensation or state of weakness caused by the need of food." Simply put, hunger is a signal from your body that it needs food for energy. When you're truly hungry, your stomach, brain, or both will give you cues to tell you to eat. Signals from your stomach may be growling, an empty, hollow feeling, or hunger pangs. Your brain may send signals such as a headache, trouble concentrating, irritability or fogginess. Some people even experience physical fatigue when they are hungry. Hunger does not go away over time--it only gets worse. And any food will satisfy your hunger and take the hunger signals away.

Strength training helps reduce the risk of diabetes.
True emoticon
Regular strength training at a moderate intensity helps prevent diabetes in a number of ways. First and foremost, lifting weights helps improve the way the body processes sugar. Researchers have also found that weight lifting helps to improve insulin sensitivity and blood glucose control. Additionally, as stated above, resistance training improves heart health by controlling cholesterol and blood pressure, both of which play a role in diabetes management.

For best results, you should increase the amount of weight you lift every time you workout.
False emoticon
Progressively overloading your muscles is the key to effective strength training. But increasing the weight you use too rapidly can lead to burnout, chronic soreness, and overuse injuries. A better approach for most people is to increase the weight (by about 10%) when you can reliably do the higher number of reps each time in good form. These are the 4 Signs You Need to Lift More Weight.

Don't fall for deceitful terms such as "wheat flour," "unbleached wheat flour," "multigrain," "enriched," or "stone-ground wheat flour." These are just sneaky ways of saying refined white flour.
