Do Weight Loss Supplements Really Work?

By Kate Haisch 10/26/2009 9:53:00 AM

Oftentimes, we find ourselves bombarded with advertisements for weight loss, muscle-building and athletic-performance-enhancing supplements. 

Do they really work?  Do they really help people lose weight and build muscle?  Let's take a look at some of the more popular supplements in the market today.

 

 

Chromium


Chromium is an essential trace mineral that appears to have a beneficial role in the regulation of insulin action in the body. There have been some evidence that suggest Chromium may help control diabetes and may lower cholesterol.  Many people use Chromium to help reduce body fat and increase muscle strength.  However, it has been proven that Chromium does not enhance weight loss and does not help increase muscle mass.  Chromium is found naturally in broccoli, ham, potatoes, green beans, turkey breast, apples, white rice, bananas and whole wheat bread.  It can easily be found in a regular balanced diet, which renders supplementation unnecessary.

Carnitine

Carnitine, L-Carnitine, is a naturally occurring amino acid.  Red meat and dairy products are rich sources of carnitine. Other natural sources of carnitine include nuts and seeds as well as vegetables and fruits like asparagus, broccoli and brussel sprouts, apricots and bananas.   Supplementation is not necessary for healthy people following a regular balanced diet.  However, people diagnosed with a carnitine impairment may need supplemental carnitine.  Research suggests carnitine may be beneficial for people with cardiovascular disorders and may help slow cognitive impairment in people with Alzheimer’s disease.  Contrary to popular belief there is no research evidence that proves supplemental carnitine can improve athletic performance and enhance weight and fat loss. 

Coenzyme Q10

Coenzyme Q10 is a fat-soluble, vitamin-like substance produced by the human body.  There have been some evidence that it may help improve exercise ability in people with cardiovascular disease. However, it does not appear to increase athletic performance. Red meat is a rich source of Q10, particularly reindeer muscle meat and animal organs such as liver and heart.  Coenzyme Q10 is found naturally in beef, chicken, pork chops, trout, salmon, oranges and broccoli.

It is important to note that statin drugs such as Lipitor and Zocor, which lower cholesterol, can inhibit the body’s ability to create Coenzyme Q10 by as much as 40%.  If you are taking statin drugs Nutrition for You recommends that you ask your medical doctor about taking Coenzyme Q10 supplements.

5-Hydroxy-Tryptophan

5-Hydroxy-Tryptophan, 5-HTP, is derived from the seeds of Griffonia simplicifolia, a plant found in Africa.  It is believed to have anti-depressant qualities and can also enhance weight loss as well as relieve stress and pain.  Supplemental 5-HTP helps raise serotonin levels in the brain.  Since serotonin helps regulate mood and behavior, 5-HTP may be beneficial for people with mood and sleep disorders.  However, no large-scale studies have proven this.  It does not appear to affect weight loss, stress or pain.  Furthermore, there have been reports of 5-HTP dietary supplements causing nausea and stomach pain.  In November 1990, the FDA banned all tryptophan-containing supplements such as 5-HTP in response to an outbreak of Eosinophilia-Myalgia Syndrome (EMS) that was linked to the use of tryptophan.

Creatine

Creatine is a substance created by protein building blocks within the body.  Natural sources of creatine include herring, pork, salmon, beef, cod and milk.  Creatine supplements are often taken by body builders to develop more muscle mass. There is some evidence that creatine may increase muscular strength during short periods of high-intensity short-term exercise. It may also help increase muscular strength in people with muscular disorders.  However, there is no evidence that creatine accelerates fat metabolism. 

It is important to note that people taking creatine should not consume more than 2g to 5g per day.  Furthermore, people with kidney disorders should not take creatine.  Lastly, there is some evidence that suggest caffeine may negate some of the effects of creatine.   For more information on creatine supplements before and after workout please talk to your Nutrition for You coach.

Whey Protein

Whey protein is the liquid material created as a by-product of making cheese.  It is equivalent to the protein quality of low-fat and fat-free dairy products and lean cuts of meat.  Taking whey protein in moderation is perfectly fine for healthy individuals.  There are no known adverse side effects.  It is always best to get your protein allowance from whole food sources, however, whey protein can be a good supplement to take after working out.  Whey protein by itself will not build muscle mass but it will help replace protein in the body after strength training.

Remember that it is always best to get all of the necessary vitamins, minerals and nutrients from whole foods first.  The best way to ensure your body is receiving all the nutrients it needs to be healthy is to eat a diet rich in whole grains, fruits, vegetables, lean protein, some dairy and heart-healthy fats.   Nutrition for You can put together a plan tailored to meet all of your nutritional needs.   If you are interested in building muscle mass please talk to your Nutrition for You coach.

Are Supplements Safe?

By Kate Haisch 10/20/2009 8:37:00 AM

Over the years, sales of supplements have steadily increased and billions of dollars have been spent on supplements each year.  More than 40% of Americans regularly take some sort of dietary supplement. Do we really know what we are taking? Are supplements safe?

In this series of blogs, Nutrition for You discusses the most popular supplements in the market today. We will talk about the pros and cons, which hopefully will help you in making an informed decision.

Are Supplements Safe?

Supplement safety is difficult to assess. Unlike drugs, the FDA does not regulate supplements.  There is no process that approves supplements before they are marketed and sold to the public and there are very few human trials done regarding supplement interactions. In addition, supplement manufacturers are not required by law to provide warnings or information about potential side effects. There are also no standards for potency or dosage. However, there are several websites that monitor supplement safety. One of them is MedWatch, the FDA Safety Information and Adverse Event Reporting Program. MedWatch alerts provide timely new safety information on human drugs, medical devices, vaccines, dietary supplements, and cosmetics. 

If you are considering taking supplements, Nutrition for You recommends that you talk to a health care professional first and get as much information as you can about the safety of these supplements.

Remember that it is always best to get all of the necessary vitamins, minerals and nutrients from whole foods first.  The best way to ensure your body is receiving all the nutrients it needs to be healthy is to eat a diet rich in whole grains, fruits, vegetables, lean protein, some dairy and heart-healthy fats.  Nutrition for You can put together a plan tailored to meet all of your nutritional needs.

Is there a difference between a registered dietitian and a nutritionist?

By Nutrition for You 10/11/2009 8:16:00 PM

Many Americans struggle with finding the right source for help about nutrition and weight loss. A lot of people rely on weight loss celebrities, personal trainers or health and fitness magazines and websites. But the most accurate and science-based information can only come from registered dietitians or RDs.

Anyone can call himself or herself a nutritionist but RDs are the nutrition professionals with the right credentials. RDs are licensed by the Commission on Dietetic Registration of the American Dietetic Association. They can legally practice medical nutrition therapy and are highly trained in multiple forms of nutrition counseling such as cognitive behavioral therapy, motivational interviewing, and dialectical behavioral therapy.

A good RD should have received a bachelor's or advanced degree from an accredited college or university, should have completed an extensive internship program that includes supervised clinical experience and should have passed a national licensing exam.

If you are looking for a nutrition professional to help you with weight loss or a health-related nutritional need, we highly recommend that you work with a registered dietitian. RDs base all their work on sound science. For example, here at Nutrition for You, the meal plans are created by a highly experienced RD in weight loss and weight management. In addition, the nutrition coaches that give one-on-one counseling in Nutrition for You are RDs or work closely with an RD and are on their way to becoming RDs themselves.

What foods can be good for the eyes?

By Kate Haisch 9/15/2009 3:05:00 PM


Everyone should take care of their eyes.  More so with age, since eye cataracts and age-related macular degeneration are the leading causes of blindness in older adults.  Proper nutrition is always the most powerful preventive medicine and so you may ask what foods can be good for the eyes?

Nutrition for You recommends the following list of foods that can help you keep your eyes healthy and your vision sharp. 

 

 

Leafy greens such as kale and spinach because they are packed with the antioxidants necessary to reduce incidents of eye  cataracts, as much as 18% based on recent studies. Other vegetables that contain these beneficial antioxidants include broccoli, corn and pumpkins.

Eggs, likewise, contain the antioxidants found in leafy greens that are helpful in keeping your eyes healthy.   However, keep in mind that eggs should be consumed in moderation, particularly when you are trying to lose weight.

Vitamin C-rich food can help provide protection from UV light damage. Excellent sources of Vitamin C are citrus fruits, red bell peppers, strawberries, raspberries, broccoli and brussel sprouts.

Vitamin E-rich foods can help in the prevention of cataracts and age-related macular degeneration. Excellent sources of Vitamin E are sunflower oil, peanut butter, wheat germ and almonds. 

Foods rich in omega-3 fatty acids can lower risk of age-related macular degeneration.  Nutrition for You recommends taking 1,000 mg of fish oil daily or eating 8 oz of salmon each week.  Flaxseed and walnuts are also excellent sources of omega-3 fatty acids.

KFC's Double Down is Double Thumbs Down

By Nutrition for You 9/8/2009 10:25:00 AM

Is KFC following the low carb trend?

It seems like it with their latest high-calorie creation, the Double Down Chicken Sandwich: it's bacon, swiss cheese, pepper jack cheese and the "Colonel's special sauce" sandwiched between two fried breaded chicken fillets instead of buns.


Clearly, there is no nutrition benefit in replacing two buns, which are equivalent to 2 grams of fat and 160 calories, with two fried chicken fillets.  The KFC Double Down sandwich has an astounding 590 calories, 31 grams of total fat, 10 grams of saturated fat, 190 mg of cholesterol and an unknown amount of sodium.  Instead of cutting down the carbs, KFC should be reducing the fat.

With over 60% of Americans suffering from obesity, how can we save money in health care if we are creating more problems?  A recent national study estimates that obesity costs $147 billion a year.  Obesity has been linked to common chronic diseases such as diabetes, stroke, heart disease and cancer.   We need a sound and evidence-based message to combat the obesity epidemic in America and, seriously, KFC is not helping.

How can I keep my energy up during the day without ruining my diet?

By Nutrition for You 8/20/2009 3:45:00 PM

 

On days when staying awake and focused seem nearly impossible, how can I keep my energy up during the day without ruining my diet with too much caffeine and sugar?

Before we talk about nutrition, we need to talk about sleep. Just cutting down your sleep by one hour will have a huge negative effect on your energy for the rest of day. Nutrition For You doesn't recommend a particular number of sleeping hours per night.  We all have our own individual sleep needs but it is very important to realize that if we don't meet them for a few days, no matter how good we eat, we will feel exhausted because of not getting adequate amount of rest. 

Aside from lack of sleep, there are chronic health conditions that can leave you constantly fatigued such as fibromyalgia and diabetes. Low-level depression and anxiety can also cause fatigue. These health issues may negatively affect your energy and focus throughout the day and it is important to discuss these issues with your doctor as soon as possible.

Assuming that you are sleeping enough and that you are addressing any health issues that can cause fatigue, proper nutrition can help you maintain a consistently high level of energy throughout the day.  Here are some key points.

 

A clear mind can boost your energy

Recent research shows that improving your cognition boosts your energy.  In other words, a clearer mind can make you feel more energetic.  Consuming foods that are rich in Omega-3 fatty acids can improve cognition.  In addition, the anti-oxidants in these foods can help your brain function and boost your memory.  Flax seeds, walnuts, and soybeans are particularly good sources of Omega-3 fatty acids.  Nutrition for You suggests consuming six to eight ounces of salmon per week.  However, if you cannot get salmon regularly, you can supplement your diet with fish oil.  Nutrition for You also recommends eating extra servings of fruits, vegetables, legumes and whole grains.  All of these will help keep your mind clear and engaged and boost your energy.

 

Eat before and after working out

Skipping meals before and after exercising can deplete your sugar significantly and make you feel tired for the rest of the day.  This underscores the importance of having both pre- and post-exercise meals.  The difference between the two may be crucial for a bodybuilder doing resistance training or a marathoner doing endurance workouts but for the average person, a general pre- and post-workout meal plan is relatively simple to put together.  Nutrition for You recommends consuming 20 to 30 grams of carbohydrates and 15 to 20 grams of protein an hour before working out.   For example, you can have a banana with yogurt or a slice of whole wheat bread with low-fat cheese before exercising. 

It is equally important to eat after completing a physical activity.  Nutrition for You recommends consuming 30 grams of carbohydrates and 25 to 35 grams of protein within 15 to 30 minutes after working out.  For example, plan to bring a turkey sandwich or a banana and cheese to the gym with you. If you are really pressed for time, a shake or smoothie can be good as long as it contains both carbohydrates and protein.  It is important to stress that the post-exercise meal should be consumed within 15 to 30 minutes after working out.

 

Eat enough of the right stuff

To keep your energy up throughout the day, you need enough of the right calories from a combination of carbohydrates, proteins and healthy fats, ideally in every meal.  Avoiding carbohydrates and fats or skipping meals entirely can adversely affect your energy level.

Nutrition for You strongly recommends that you have breakfast within an hour of waking up.  You fast all night while you sleep and so it is important to break that fast as soon as you can after waking up and to do so with a balance of carbohydrates, fiber, and protein. For example, if you have yogurt, add a fruit; if you have bread, add egg whites or cheese.

As for the rest of the day, always remember to eat and avoid fasting for too long. Eating sensibly every three hours levels out blood sugar spikes.  In general, an average person should consume roughly 600 to 700 calories for lunch and 500 to 700 calories for dinner.  It is important to note that eating too much in a single meal may slow you down.   Dumping too many calories all at once takes a toll on your body and may make you feel tired. 

Finally, eating refined carbohydrates such as white bread, noodles and white rice may give you a sudden spike in energy because they raise your blood glucose.  However, a surge of insulin will knock down the sugar and will linger after the sugar is absorbed. This will give you low blood sugar and, consequently will make you feel fatigued and prematurely hungry again.

 

Drink the right fluids

Sometimes fatigue is actually caused by dehydration even if you don’t feel thirsty.  If you consume enough fruits and vegetables as well as healthy soups then drinking five to six cups of water per day will keep you well hydrated.

In addition, you should try to avoid alcohol. Since alcohol is a depressant, consuming alcohol can contribute to your low energy.  Excessive drinking can definitely wear you down and excessive alcohol greatly dehydrates your body. 

 Adequate amount of sleep and rest combined with proper nutrition is the key to maintaining your energy up throughout the day.  Nutrition For You can help you develop a customized meal plan to help you achieve your specific nutrition and weight management goals.

Are bananas fattening?

By Nutrition for You 8/6/2009 8:09:00 AM


Many Americans think bananas are fattening because they are high in calories and more dense in carbohydrates compared to other fruits.  This is not true.  Bananas, like any other fruit, are fattening when consumed in excess, which underscores the importance of understanding serving sizes.  A serving of bananas is 4 oz in weight, which is equivalent to ½ a large banana.  And so consuming a whole large banana is equivalent to having two servings of fruit.  Having a banana most days of the week, therefore, can be part of a healthy eating lifestyle.Bananas
 
One serving or ½ a large banana contains approximately 15 grams of carbohydrates.  In comparison, one can get this much carbohydrates in one serving of any fruit.

½ a large banana = 1 cup of berries = 1 medium size apple = 2 tbsp of raisins = 4 fl oz of fruit juice = ½ cup of fruit salad

Furthermore, bananas are a great source of phosphorous, calcium, potassium, vitamin A, vitamin C, niacin, vitamin E and vitamin B6.

Since bananas are a great source of carbohydrates and potassium they are perfect to have as a pre-exercise meal or an on-the-go snack.  Bananas are also great to eat for people who wish to lower their blood pressure.

What’s Brewing? Coffee's health benefits.

By Nutrition for You 8/4/2009 10:40:00 AM

 

Many Americans love a good cup of coffee.  But the nutritive value of this beloved beverage has remained under scrutiny.  More recent medical studies, however, show that drinking regular or decaffeinated coffee moderately can actually provide numerous health benefits. Cup of Black Coffee, Photography by Jun Belen


Health Benefits

Coffee is rich in a variety of anti-oxidants which researchers believe may be responsible for its cancer-fighting and disease-preventing benefits.  For example, research studies suggest that moderate coffee consumption may be linked to a decreased rate of Type 2 diabetes and liver cancer.  Drinking coffee moderately may also reduce the risks of stroke as well as skin, colorectal, breast, oral, pharyngeal and esophageal cancer.  It may also lower the chances of Alzheimer’s and Parkinson’s disease.  


Caffeine and Athletic Performance

The caffeine contained in coffee has been shown to boost endurance and improve performance in athletes.  Recent studies show that caffeine consumption results in enhanced performance during short-term and intense aerobic exercise lasting from 4 to 8 minutes, as well as from 20 to 60 minutes.  Researchers believe that the benefits may be due to a reduced perception of effort or a direct effect on the muscles.  Caffeine is quickly absorbed and reaches its peak within an hour of ingestion.  Studies show that low doses of caffeine are most effective when consumed before or during exercise.  For a person weighing 150 lbs, this would be 68 to 205 mg of caffeine, which is approximately the amount of caffeine contained in a single cup of coffee.  It is important to note, however, that no improvements regardless of the dose were observed for those who are not trained athletically.

Despite its benefits of enhanced athletic performance, many athletes are concerned with caffeine’s suspected diuretic effect.  When consumed in moderation, caffeine is not likely to increase the discharge of urine or cause dehydration.  In fact, there is no scientific evidence that links caffeine consumption with excessive urine discharge.  On the contrary, caffeine-containing beverages may be a good source of fluids for athletic activity.  


Blended coffee drinks are calorie bombs

Coffee, by itself, is a great low-calorie beverage.  However, it is important to be aware that some popular blended coffee drinks are notorious calorie bombs.  Laden with sugary syrups, whole milk and whipped cream, these coffee beverages are loaded with sugar and saturated fat.  For example, Starbucks’s Venti Frapuccino blended coffee drink is packed with as much as 600 cal, 200 g of fat and 100 g of sugar.  For some people, that’s almost half the calories needed for the whole day!

 
Nutrition for You recommends

If you are a coffee drinker, Nutrition For You recommends that you consume coffee moderately, without exceeding 4 cups per day.

However, if you are not, Nutrition For You recommends that you do not start.  Caffeine in coffee can significantly increase the levels of the “stress hormone” cortisol that can adversely affect your health. Look for more information on caffeine soon.

Stay fit with the super sweet potato

By Nutrition for You 7/29/2009 9:47:00 AM

 

Who would have thought those Thanksgiving yams can help you stay fit and healthy?

Sweet potatoes are packed with essential vitamins and minerals.  It is an excellent source of vitamin A in the form of beta-carotene, a very good source of vitamin C and manganese and a good source of vitamin B6, copper, potassium and iron.

Sweet potatoes have antioxidant properties that may prevent conditions such as atherosclerosis, diabetic heart disease, and colon cancer.   They contain anti-inflammatory properties that have been shown to reduce the severity of conditions such as asthma, osteoarthritis and rheumatoid arthritis.  

And best of all, a half cup serving of sweet potatoes is only 80 calories.  It cannot get any sweeter than that.

Eat sweet potatoes along with a heart healthy fat.  The beta-carotene in sweet potatoes can only get converted to vitamin A in the presence of bio-salts, which are released when consuming fat.  Finally, it is important to note that the carotene content of sweet potatoes actually increases as they are stored throughout the winter.
