Dr. Brian Arcement Talks About hCG

hCG is quickly gaining popularity in the weight loss world as the magic remedy for quick and easy weight loss. What are the facts about hCG? Is it safe? Does it really work? Recently, LoveToKnow had the opportunity to speak with Dr. Brian Arcement, Medical Director of Nuviva Medical Weight Loss Clinics in Florida, about how hCG works and why.

LoveToKnow (LTK): Dr. Arcement, can you provide a little background on yourself and what makes you qualified to speak on hCG?

Dr. Brian Arcement (BA): I am a graduate of the University of South Alabama College of Medicine and completed my residency in Internal Medicine, a Fellowship in Cardiology at the University of Florida Health Science Center-Jacksonville and a second Fellowship in Interventional Cardiology at Vanderbilt University Medical Center-Nashville. I am also a diplomat of the American Board of Anti-Aging Medicine.

As a Quad certified and Board certified interventional vascular cardiologist, I have been practicing for more than a decade. Through the course of my work, I have seen the physical devastation of poor lifestyle choices and the aging process on the human body. Therefore, during my years of professional practice, I now see weight management as a vital component in long-term health.

In addition, I have been utilizing hCG for over five years through my Hormone Replacement Therapy practice specifically for men with testosterone deficiency and most recently with the medically assisted weight loss program I designed through Nuviva Medical Weight Loss. In addition to my experience, I am comfortable with the Nuviva program's use of hCG for weight loss based on the anecdotal evidence we have seen through our clinics as well as the clinical experience other weight loss clinics nationwide have demonstrated through the successful treatment of thousands of clients.

LTK: What is hCG?

BA: HCG, or human chorionic gonadotropin, is a hormone produced by women during pregnancy. The hormone is primarily responsible for maintaining a viable fetus, particularly during the first trimester. Additionally, it is thought that hCG causes a physiologic occurrence making stored fat available as a nutrient source for the growing fetus.

LTK: Why does it help people lose weight?

BA: HCG is believed to help the body utilize stored fat for calories and to reduce the body's tendency to use lean muscle mass as an energy source when combined with a very low calorie diet.

LTK: In what forms is hCG available?

BA: Although hCG is available in several forms, including subcutaneous (or injectable), topical, sublingual and homeopathic, I recommend only the use of pharmaceutical grade subcutaneous hCG.

This is because the subcutaneous route is the only method known to directly control the proper amount of hCG given. hCG given sublingually requires at least double to triple the amount of injectable hCG to ensure that some hCG is absorbed. However, the amount absorbed can vary from client to client based on each individual's oral mucosa. This same reasoning applies to topical hCG and why I do not recommend its use.

Additionally, some clients are even incapable of absorbing any hCG topically or sublingually. Oral hCG has no biologic effect as the hCG is immediately broken down by acid in the stomach. The only method available to provide absolute certainty that the correct amount of hCG prescribed is given is to inject the hCG subcutaneously.

LTK: How is hCG best taken to be the most beneficial?

BA: My recommendation is found in the Nuviva protocol, which allows for a client to take 150 units of subcutaneous hCG daily six days a week. Also, we have seen through the course of our work with clients that hCG loses its effectiveness after a certain amount of time. Therefore, I recommend clients cycle on and off hCG in specific time frames in order to maximize its effectiveness.

LTK: Is the weight loss permanent or does a person have to keep taking hCG to maintain their weight loss?

BA: Once a client has reached their goal weight, they no longer need to take hCG to maintain their weight loss. As hCG is only utilized in one of the four phases of the Nuviva program, a mainstay of the program includes teaching our clients the tools and providing them with the resources they will need to maintain their weight loss gains for life.

For many people, weight loss is a chronic endeavor. All too often the shedding of pounds is a temporary event followed by a steady regain of lost weight. This is because most individuals do not learn how, what and how much to eat in order to properly fuel their bodies. They are not educated about proper food choices and effective exercise. Through the Nuviva program clients learn to count calories, eat real food and understand how their body will process food, the only way to maintain weight loss gains for the long-term.

A further component of the Nuviva program that assists people in maintaining their weight loss gains is through better understanding of each client's own body. In Phase Four, we utilize a Resting Metabolic Rate Machine to find the client's very own Resting Metabolic Rate (RMR). This is a number that is unique to each individual client. It is the number of calories their body will burn everyday even if they sustained no physical activity. From this number, we determine the right number of calories for the client and their metabolism. Knowing your Metabolic Rate helps you to know how to balance what you eat with what you burn. If this number and balance is adhered to, each client will be able to manage their weight for life.

LTK: How long before results are seen and what rate of weight loss is typical?

BA: Once a client begins taking hCG, it takes three days to become fully active in the body. For this reason, most people will see only moderate weight reduction within the first week on hCG. From this point on, weight reduction is unique to each client but can range from two to five pounds a week.

LTK: What research has been done on the safety of hCG for weight loss?

BA: For many years, physicians have safely prescribed hCG to assist overweight patients in reducing their weight. To date, however, these implications for hCG have not been proven in medical studies and the FDA has not approved the use of hCG for medical weight loss.

However, through our clinics, we have helped thousands of individuals with their weight loss goals and have seen the anecdotal evidence of the effectiveness of hCG for long-term weight loss. Studies are currently being conducted on the use of hCG for weight loss, and I believe these studies are a direct result from proven success of individuals utilizing hCG for safe and effective weight loss.

LTK: What side effects are typically seen?

BA: Typical side effects associated with hCG diets include hair loss, headaches and nausea. However, these side effects are often signs of nutritional deficiency. We have addressed this issue through supplying clients with specially blended supplements, vitamins, minerals that correspond with each phase of the Nuviva program. Patients who experience these symptoms would have their calories increased or have their diet and supplements reviewed to make sure they are appropriate.

LTK: Who should not use hCG?

BA: Women who are pregnant or who are actively trying to become pregnant should not use hCG. Also patients with a prior history of DVT (deep vein thrombosis), especially women with a history of DVTs while receiving hCG for infertility treatments should not take hCG. Additionally women with active breast cancer and men with active prostate cancer should not take hCG.

As with all weight loss programs, I recommend anyone considering a hCG diet consult their physician to determine if the program is appropriate based on health, medical history and personal weight loss needs.

LTK: What else can you share about the safety of hCG and weight loss?

BA: If someone is considering a weight loss program that incorporates hCG, I recommend they do so in a medically supervised environment and use only pharmaceutical grade hCG as one component in a comprehensive weight loss program that emphasizes proper nutrition, exercise and healthy lifestyle changes to sustain long-term weight loss.

Additionally, a common misconception regarding hCG is that it introduces high amounts of hormones into ones body. hCG is given in very small doses during third phase of the Nuviva program, the hCG diet phase. To put this into perspective, women using hCG for medical purposes, such as fertility treatment, would inject between 50 and 100 times the dose that we prescribe through the Nuviva program or what you may find in a typical hCG diet.

Interestingly, hCG is currently being studied for implications beyond weight loss, including reduction of breast cancer occurrences for women and prostate issues, including prostate cancer, for men.

It is important to note that at this time hCG usage in the above-mentioned ways is only in the research phases. It is not recommended that hCG be used for the treatment of breast cancer or prostate cancer. Additionally, until further studies have been conclusively conducted, hCG should not be prescribed to patients who have active breast cancer or prostate cancer. However, I am encouraged by the potential that one day hCG may prove to be a new and exciting treatment for both of these life threatening diseases.

LoveToKnow would like to thank Dr. Brian Arcement for taking the time for this interview. If you think you'd like to try hCG for weight loss, talk to your doctor to see if it is a good idea for you. You can also learn more by visiting NuvivaWeightLoss.com.

New Weight Watchers Program Points Plus

Weight Watchers has always stressed the importance of healthy food choices in their weight loss programs, and their new Weight Watchers Points Plus program continues to emphasize this point. In addition, the revamping of their original weight loss program takes into account the fact that not all calories are created equal and thus the idea of "counting points" was reexamined and a new program created.

The new Weight Watchers Points Plus program offers quite a few changes from the original version. The new program emphasizes the need to look not just at caloric intake but also at the quality of foods you choose for the program. While you will still count points, the point system has changed with points for many foods, especially those that are processed or contain sugars, being much higher in value and points for other foods, like fruits and vegetables, containing few or even zero points.

The Points Plus program encourages participants to choose foods rich in fiber and protein and limit those foods that contain empty calories. No longer are 100 calorie snack packs and a 100 calorie apple treated as equal. Foods which are high in fat and simple carbohydrates are assigned more points, while fiber-rich foods are assigned fewer or zero points. To participate in the program, dieters do the following:

Fill out a form listing age, gender, height, and current weight. Receive assigned Points Plus daily and weekly allotment based on the above information. Eat at least 1200 calories daily. Calculate points based on the new system, which typically allows more daily and weekly point values. Calculate points based on how hard the body works to process certain foods, such as protein and fiber as opposed to fats and carbohydrates. Participate online, in person, or as a combination of the two.

The most important part of the Points Plus program is choosing the right foods. While the old program gave point values to fruits and vegetables, the new program allows dieters unlimited quantities of fresh fruits and non-starchy vegetables. The program takes into account the 2010 USDA Dietary Guidelines and stresses the importance of eating three well-balanced meals as well as healthy snacks. The program also encourages participants to fill up on "power foods" which include the following:

Whole grains Lean meats, such as chicken, turkey, and fish Fresh fruits Non-starchy vegetables, such as asparagus, bamboo shoots, green beans, beets, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celery, cucumber, eggplant, collard greens, leeks, mushrooms, okra, onions, peppers, radishes, spinach, sugar snap peas, squash, tomato, turnips, zucchini Low-fat dairy

If you've participated in the original Weight Watchers program, you'll see several differences between it and the new Points Plus Plan.

The old plan focused more on caloric intake. The new plan focuses on filling up on healthy foods. The old plan allotted points based more on calories rather than on the type of food. The new plan focuses on whether foods contain protein and fiber as opposed to foods which are high in sugars and carbohydrates. The old plan allotted points to fresh fruits, such as 1 point for a small banana or apple. The new plan allots a point value of 0 to fresh fruits.

While many dieters found success with the original Weight Watchers plan, the new plan takes into account the importance of choosing healthy foods. As you embark on this new diet program, however, it's important to keep a few points in mind if you are going to find success.

Throw away all your old point value information, and base your food choices only on the Points Plus plan. Don't try to combine the two plans because the point values have changed for most of the foods, and many foods have higher point values. Although fresh fruits have a zero point value, don't think you can stuff yourself with fruit. Eat until you are satisfied.

Finally, use your points wisely, and choose those power foods that will provide your body with plenty of protein and fiber. The Weight Watchers Points Plus Program will change the way you look at food and provide a safe and healthy way to take off that excess weight.

Prescriptive Stretching Interview

A regular stretching routine is an easy way to prevent injuries, eliminate pain, and improve balance and flexibility. However, it is essential to understand how to stretch properly. In the book Prescriptive Stretching, author Kristian Berg outlines the fundamentals of proper stretching and explains how to use stretching to ease pain and minimize injuries.

Kristian Berg lives in Svartsjo, Sweden. He maintains a clinic in Stockholm where he practices as a doctor of naprapathy, helping to ease the pain of his patients though the manipulation and stretching of connective tissues.

Recently, LoveToKnow was able to speak with Kristian Berg about the benefits of stretching.

LoveToKnow (LTK): Why is stretching important?

Kristian Berg (KB): Our natural range of movement has decreased because we are less active and sit for longer hours. Stretching could be one way to increase our range of movement and reduce different kinds of pain.

Depending on your goal, stretching can help you perform certain movements that you haven't been able to do before because it increases your flexibility. But it can also help reduce/remove pain that is caused from inactivity.

LTK: Is stretching just for athletes or people who are very active?

KB: No absolutely not, stretching is for everybody! Inactivity will cause a reduced range of movement which is directly linked to different kinds of pain. Sometimes stretching is even more important if you are inactive.

LTK: How can stretching prevent injuries?

KB: Stretching will help to elongate tight muscles. A tight muscle will affect the way we move and our posture which in itself could cause an injury. But it will also affect how we perform an exercise; a tight muscle will change our range of movement which will strain the joint capsules and put pressure on other muscles.

Some research shows that regular stretching performed in a correct way during at least one year will decrease the risk of injury amongst soccer players.

LTK: If someone is in pain, should they avoid stretching?

KB: It all depends on what kind of pain. If you have a fracture, acute torn ligament/muscle or a dislocated joint, stretching should be avoided.

If the pain is caused by other factors, stretching could definitively help as long as it is performed in a correct way. It is also important to remember that the stretch can be felt in other areas than where the pain is.

LTK: What is the best way to stretch?

KB: You should follow these four rules:

Stretch slowly The stretch should be pain free (good pain, not negative pain) Stretch the right muscle Do not affect the joint capsule or other muscles

You don't have to warm up, however, it all depends on which activity you are about to perform. If you are very stiff/stale it will probably feel much better to stretch when you are warm than cold.

If you are about to do a training session with very explosive movements, stretching has shown a negative effect. But if it comes to warming up before a normal training session or a long run it has the opposite effect.

LTK: Are all stretching exercises the same?

KB: There are different ways to stretch, for example, a hamstring muscle. In the end it is the stretch that takes the origin as far away from the insertion as possible without affecting other muscles or joints that will be the most effective stretch.

Further, there are also different techniques that can be used. PNF stretching is one of the most effective techniques when it comes to increasing the range of motion. The technique is simple, safe and has three phases:

Stretch the muscle for 10 seconds Contract the muscle for five seconds (which will facilitate muscular inhibition) - this is a very important phase! Relax the muscle for five seconds, then try to stretch even further

LTK: Can people rely on stretching exercises for a total fitness routine?

KB: No, but it will help. Stretch exercises will not improve your cardiovascular or muscular fitness (strength). A good fitness routine should entail stretching and some training each day which involves both the heart and the muscles.

LTK: Anything else you'd like to share on the benefits of stretching?

KB: The most important thing is to not "just stretch." To "just stretch" with a bad technique or done haphazardly will not help in the same way as a properly performed stretch that is done on a regular basis. To get the most out of stretching it should be done properly and on a regular basis, i.e. up to 10 times each day depending on the pain and intensity.

Hydraulic Exercise Equipment

Many gyms feature hydraulic exercise equipment as part of their circuit training apparatus. These machines provide a popular strength training alternative to equipment utilizing weight stacks.

First developed in the 1970s by the Henley Corporation, hydraulic exercise equipment provides resistance against movement of a lever pushing against hydraulic fluid in a piston. Because there are no weight stacks with set weights, using a hydraulic machine for resistance training allows you to fine-tune the resistance for your individual strength training level. Likewise, the hydraulics resist only as you apply force, and it responds to the speed and level of force you apply to your movements. As a result, you determine how difficult your workout is by your energy and movements rather than relying on the weights to control the intensity of your workout. If you move more quickly or exert more force, resistance increases. If you move more slowly or exert less force, resistance decreases.

At-home cardiovascular fitness training equipment may also be hydraulic. The same principles apply to hydraulic cardiovascular equipment: you control the workout and intensity by the force and speed of your own movements.?

Hydraulic exercise equipment typically utilizes separate machines to isolate specific muscle groups. The actions that you perform on such equipment mirrors activities on weight-based machines. The major difference is in how the machines supply resistance.?

The uniquely customizable features of a hydraulic machine yield many benefits:

You can go at your own pace, making the equipment ideal for special populations such as children, the elderly, and people recovering from injuries.Hydraulic strength training and cardio equipment allows you to exercise at a level with which you are comfortable, because you have ultimate control over the resistance it provides.People using hydraulic equipment experience reduced soreness.It allows people of all fitness levels to train on the same equipment.It can be tailored to help meet individual fitness goals.The specificity of each movement helps you avoid injury and allows you to train specified areas.Hydraulic aerobic equipment yields a quieter workout, and the intensity is up to you.

The equipment has drawbacks, as well:

Hydraulic resistance machines may not supply as smooth of a range of motion as weight-based machines.Most hydraulic resistance machines have a top weight that may be lower than weight-based machines.The resistance machines may not provide sufficient resistance for advanced athletes or extremely strong individuals.The hydraulic resistance-training equipment is not as versatile as weight-stack machines, and you usually need multiple machines to get a full body workout. This makes it impractical for home users.At-home hydraulic cardio equipment may have lower weight limits, putting it out of reach of some obese individuals.

You typically find hydraulic strength training machines in gyms and fitness centers. Many gyms geared especially towards women feature hydraulic equipment. Many retail outlets sell at-home cardio training hydraulic equipment, such as the Bowlfex Tread Climber and the Sears Precision Rower.

If you've been looking for a customizable workout that works with your own unique goals, hydraulic fitness equipment may be right for you. Talk to a fitness professional to determine how to incorporate these machines into your workout routine.

Free 2,000-Calorie Diet Plans

A 2000 calorie a day diet plan provides enough calories to include a variety of healthy foods to keep menu items interesting and your body fueled. If you're considering a 2000 calorie plan for weight loss or maintenance, it's fairly easy to follow once you learn how to track calories and substitute lower-calorie foods and drinks for some of your higher-calorie favorites.

If you're looking for dieting inspiration, you can find a number of free 2000 calorie diet plans on the Internet, or you can create your own by learning how to pare down calories in your favorite recipes. This takes a little extra work on the outset, but once you know the calorie content per serving for a recipe, the hard part is done. Some recipes come with calorie and serving size information included.

The Calorie Control Council offers a 2000 calorie a day plan to encourage people to eat healthy, balanced meals. They not only offer a sample menu for seven days of meals, but they also provide a list of tasty low-calorie recipes to help build your lower-calorie recipe collection. They also offer a list of healthy substitutions to help you convert your own recipes, too.

Drugs.com offers the basics for a 2000 calorie diabetic diet. This diet is calorie controlled and designed to help control blood sugar as well as lose weight. A sample menu offers ideas for items to prepare, but also provides specific measurements for dieters to learn how to measure serving sizes.

While DietBites offers a free 2000 calorie meal plan, they also recommend you change your diet to the number of calories required for your size. Other recommendations include setting a realistic goal weight based on your true frame size. This diet offers a healthy balance across all the food groups and a sample menu to get you started.

MyPyramid.gov offers a seven day menu plan for a free 2000 calorie-a-day diet. This menu also takes a balanced nutritional approach with foods selected from each food group.

Eating 2000 calories a day, whether for weight loss or maintenance, has it pros and cons:

Calorie counting works to lose or maintain weight when done diligently. Allows you to eat a wider range of foods as long as you count the calories. 2000 calories are enough calories to keep most dieters from feeling hungry as long as they make wise food choices. Measuring food portions and servings takes time. Not everyone wants to track their calories every day. Some dieters will feel like 2000 calories a day is not enough. For other dieters, 2000 calories will be too many.

Before you arbitrarily choose to follow a 2000 calorie diet plan, it is important to determine whether or not that is the right amount of calories for you in relation to your weight goal. Every person is different and the number of calories you need as an individual is determined by a variety of factors including your current weight, height, age, and activity level. For many women and smaller people, 2000 calories a day is more than they need, if they want to lose weight. Handy online calculators can help estimate the right amount of calories for you, but before you start any diet, it is best to talk with your healthcare provider. He will guide you to the plan best suited to your individual needs based on your medical history and current weight.

Supercompensation Chart and Exercise Recovery

A review of the supercompensation chart and exercise recovery illustrates the science behind training. It also shows why you need to allow time for recovery after exercise. Your post-workout time places a large role in improving your endurance and building strength.

The process of working out can be defined in four stages. When you begin exercise, your workout is defined by your stage of fitness at that point. It will ultimately determine how long and how intensely you can exercise. Your workout will then deplete your available stores of sugar, resulting in the fatigue you feel after exercise.

You will then enter the recovery period. During this time, your body will repair muscle damage done from exercise. It will replenish sugar reserves in your muscles. This period is essential for you to build endurance and strength. This is the reason behind the rest periods advised by fitness experts.

Post-recovery, your body then enters a period of supercompensation. This exact time varies with the individual. Genetics, gender, and age all influence the timing of this stage. At this point, exercising will build additional strength, again resulting in fatigue. Likewise, if you don’t train at all, you will not gain the benefits supercompensation has to offer.

The important thing to understand about supercompensation and recovery is that you will not realize the long-term benefits of exercise with just one workout. Your body treats a single workout session as a stress, initiating the so-called fight-or-flight response. In other words, it acts as if in a survival situation, maximizing energy use in the short term.

When you exercise regularly, your body adapts to increase its efficiency during exercise. You will find that exercise will seem easier because your body can meet your needs for oxygen and energy better. You will experience profound changes in your cardiovascular system.

Your body will produce more red blood cells for carrying oxygen. Your respiratory system will become stronger as will your heart. The cells of your body will contain more mitochondria, the energy centers of the body.

You should not overtax your body during the recovery stage of exercise. Doing so risks overtraining. Muscles which are not fully recovered are more vulnerable to injury. You will likely find that your performance suffers because you simply don’t have enough energy.

You can assist your body with the recovery process by doing light to moderate exercise during this period of active rest. Rather than a vigorous running session, you can walk to keep your circulation going during this time. The increased circulation will speed the delivery of nutrients to the injured site and remove the waste products as well.

During supercompensation, exercise will likely feel easier because you have built up muscle mass and recovered lost energy. At this stage, you can push yourself a little harder to build on the momentum of your increased fitness.

Bear in mind that while individuals vary in their recovery, so too do different parts of your body. The process of repairing muscle tissue will likely take longer than replenishing your sugar stores. You may wonder how you know then when it is time to exercise again taking these principles into account.

A 1998 study by Stockholm University (Sports Medicine, July 1998; 26(1):1-16) may provide the answer. The total quality recovery scale measures recovery as perceived by the individual. It uses the same principles of the ratings of perceived exertion (RPE) where you rate your effort based on how hard it feels. Both of these systems offer a way to increase your self-awareness regarding your performance and recovery.

Whether you are strength training or doing aerobic exercise, your body goes through a cycle of exercise, fatigue, and recovery, followed by a period of supercompensation where you can build endurance and strength. The key is to listen to your body and not to hurry the recovery process. Doing so will allow you to safely increase your fitness and reduce your risk of injury.

Low-Carb vs. No-Carb Diets

People considering a carb controlled diet often wonder about the differences between low-carbohydrate and no-carbohydrate diets. While the underlying principles are the same, the implementation is different. How do low-carb diets stack up against no-carb diets?

Many low-carbohydrate diet proponents believe that human beings need to avoid refined carbohydrates, sugars, and processed foods as an evolutionary imperative. Early humans were hunter-gatherers who most likely ate foods that they could either forage or kill. Some physicians, like Kurt G. Harris who invented the Archevore Diet, suggest that the human body has not evolved to process the foods that make up the bulk of the Western diet, including multiple processed foods like pasta, baked goods, and sugary snacks. Low-carbohydrate diets that focus on animal protein and vegetables mimic the eating habits of early humans, possibly providing a healthy, more natural way of eating.

In his book, Good Calories, Bad Calories, Gary Taubes explains exactly how carbohydrate consumption affects humans. When you eat carbohydrate containing foods, your blood glucose rises. In response, your pancreas releases insulin to return your blood sugar to a normal level. Insulin is the hormone responsible for storing dietary fat in your fat cells. It also keeps that fat from leaving the cells. Why does insulin do this? Because it exists to protect our body from times of famine by storing energy for lean times. Both types of diets limit the amount of insulin your body produces.

Diets in which you consume fewer than 50 grams of carbohydrates per day are considered to be low-carb. No carb diets, on the other hand, consist of zero carbohydrates. This means that you primarily eat animal protein and fat on a zero carbohydrate diet. Low-carbohydrate diets, on the other hand, allow you to eat some carbohydrate-containing foods, such as non-starchy vegetables, nuts, and moderate carbohydrate fruits. Most of the recommend low-carbohydrate diet plans, such as Atkins, Protein Power, and South Beach, recommend a moderate amount of carbohydrate intake.

Many people believe that if eating a low-carbohydrate diet will lead to weight loss, then eating a zero carbohydrate diet will bring about faster and greater losses. This isn't exactly true. Limiting carbohydrates in your diet is not the same as limiting calories and fat, and the mechanisms of loss differ. There is no scientific evidence that eating a zero carbohydrate diet will lead to faster weight loss.

Many scientists have studied low-carbohydrate diets to determine their efficacy. A 2010 Temple University study followed dieters for two years. One group of dieters ate a traditional low-fat, low-calorie diet while another group ate an Atkins-style low-carbohydrate diet. The study showed both diets to be equally effective at generating weight loss. Similar results have turned up in other studies, as well.

The only study performed on a zero-carbohydrate diet occurred in 1929 when two men agreed to go a year eating only meat. The study participants didn't lose weight, but they also experienced no predicted adverse effects of too much protein in the diet such as kidney disease or vitamin deficiencies.

Many health experts, such as MayoClinic.com, express concern that low-carbohydrate diets contain insufficient fiber, which can lead to constipation or even colon disease. No-carb diets contain even less fiber. Both low and no-carb diets are also high in saturated fat, which has been shown to contribute to heart disease.

No-carbohydrate diets are an extreme form of low-carbohydrate diets. For many, they prove difficult to maintain because of the lack of variety inherent in the diet. Most experts suggest a moderate approach to low-carbohydrate dieting that includes, at the very least, non-starchy vegetables. No discernible benefits arise from fully limiting carbohydrates.

Before going on a low-carbohydrate or no-carbohydrate diet, talk with your doctor.
