Prescription and Over the Counter Weight Loss Drugs

Prescription Weight Loss Drugs

For obese people who have difficulty losing weight through diet and exercise alone, there are a number of FDA-approved prescription drugs that may help. "On average, individuals who use weight loss drugs lose about 5 percent to 10 percent of their original weight, though some will lose less and some more," says the FDA's Colman.
All of the prescription weight loss drugs work by suppressing the appetite except for Xenical (orlistat). Approved by the FDA in 1999, Xenical is the first in a new class of anti-obesity drugs known as lipase inhibitors. Lipase is the enzyme that breaks down dietary fat for use by the body. Xenical interferes with lipase function, decreasing dietary fat absorption by 30 percent. Because the undigested fats are not absorbed, fewer calories are available to the body. This may help in controlling weight. The main side effects of Xenical are cramping, diarrhea, flatulence, intestinal discomfort, and leakage of oily stool.
Meridia (sibutramine), approved by the FDA in 1997, increases the levels of certain brain chemicals that help reduce appetite. Because it may increase blood pressure and heart rate, Meridia should not be used by people with uncontrolled high blood pressure, a history of heart disease, congestive heart failure, irregular heartbeat, or stroke. Other common side effects of Meridia include headache, dry mouth, constipation and insomnia.
Other anti-obesity prescription drugs that were approved by the FDA many years ago based on very short-term, limited data include: Bontril (phendimetrazine tartrate), Desoxyn (methamphetamine) and Ionamin and Adipex-P (phentermine). They are "speed"-like drugs that should not be used by people with heart disease, high blood pressure, an overactive thyroid gland, or glaucoma. These drugs are approved only for short-term use, such as a few weeks.
"There is no magic pill for obesity," says David Orloff, M.D., director of the FDA's Division of Metabolic and Endocrine Drug Products. "The best effect you're going to get is with a concerted long-term regimen of diet and exercise. If you choose to take a drug along with this effort, it may provide additional help."
Prescription weight-loss drugs are approved only for those with a BMI of 30 and above, or 27 and above if they have other risk factors, such as high blood pressure or diabetes.
People should contact a doctor before using any kind of drug, including a weight loss drug.

Over the Counter Drugs

Until recently, weight-control drugs containing the active ingredient phenylpropanolamine (also used as a nasal decongestant) were available over-the-counter (OTC). However, based on evidence linking this ingredient to an increased risk of bleeding in the brain (hemorrhagic stroke), the FDA asked drug manufacturers to discontinue marketing products containing phenylpropanolamine. In addition, the FDA issued a public health advisory in November 2000, warning consumers to stop using products containing this ingredient.
The FDA is proposing to classify phenylpropanolamine as "not generally recognized as safe" and is proceeding with regulatory actions that will likely remove this ingredient from the market. Although cough-cold products were reformulated using other nasal decongestant ingredients, there is no currently available active ingredient that is generally recognized as safe and effective for use in an OTC weight-control drug product.

Beware of Unproven Claims of Dietary Supplements

Some dietary supplement makers claim their products work for weight loss. These products are not approved by the FDA before they are marketed. Under existing laws, manufacturers have the responsibility for ensuring that their dietary supplement products are safe and effective.
Many weight-loss products claim to be "natural" or "herbal," but this does not necessarily mean that they're safe. These ingredients may interact with drugs or may be dangerous for people with certain medical conditions. If you are unsure about a product's claims or the safety of any weight-loss product, check with your doctor before using it.

Worth the Effort To Lose Weight

"Losing weight requires major lifestyle changes, including diet and nutrition, exercise, behavior modification, and, when appropriate, intervention with drug therapy," says Judith S. Stern, Sc.D., professor of nutrition and internal medicine at the University of California, Davis, and vice president of the American Obesity Association. "But it is always worth making the effort to improve your health."

Forgo Fad Dieting, Join Healthy Weight Campaign

The last decade can be defined by the ups and downs of different fad diets — which seem to go in and out of fashion like shoulder pads and hemlines. Yet, long-term success has been slim. Two out of three Americans — including 40 percent of Corpus Christi residents — remain overweight or obese.
A new campaign crossing the country, the Campaign for Healthy Weight, is rallying Americans behind the healthy weight cause and urging people to think more about their “health” instead of simply a number on the scale. Studies indicate that small, specific changes in physical activity and calorie intake can make a big difference. And, people who maintain a healthy weight are less likely to be at risk for weight-related health conditions, such as heart disease. The Campaign will make its stop in Corpus Christi on Saturday, October 25, 2008 to urge local residents to change their “diet” mindset and elect a new attitude.
Health management is really starting to become a bigger part of weight management. The key is to make small, sustainable changes that can last a lifetime. Drinking lowfat or fat free milk as a part of a healthy daily eating plan and walking more every day are two easy adjustments that can go a long way in supporting a healthy weight.
Weighing in on the American Diet
A new report called Weighing in on the American Diet found that the number of adults who say they are on a diet has steadily decreased over the past decade. The study, conducted by The NPD Group in collaboration with the Milk Processor Education Program, found the majority of Americans say they are on a diet for their health and their weight; 68 percent say “feeling healthier” is why they’re dieting.
People who are watching their weight, however, are making less than optimal beverage choices. Coffee, soft drinks, teas and juices are most likely filling their glasses and cups, with milk being the fifth most frequently consumed beverage — only 14 percent of all beverage occasions. The report found that adult dieters who made drinking lowfat or fat free milk a daily habit were more likely to have a healthier body mass index (BMI), a better quality diet and were less likely to feel nutrient-deprived, compared to dieters who didn’t.
Milk supplies two nutrients, that along with physical activity, are especially important when cutting calories — calcium to prevent bone loss and protein to help build muscle mass. Studies suggest that drinking the recommended three glasses of lowfat or fat free milk a day along with a healthy diet can help maintain a healthy weight. Researchers have also found that people with higher intakes of milk tend to be leaner and are less likely to gain excess weight than those who drink little or no milk.
Milk — The Beverage with Your Health Interests at Heart
People who maintain a healthy weight are less likely to be at risk for weight-related health problems, such as diabetes, heart disease, high blood pressure and some types of cancer. In addition, some studies have linked meeting the recommendations for lowfat and fat free milk along with eating fruits and vegetables to a lower risk for high blood pressure and heart disease, as part of a heart-healthy diet. The American Heart Association 2007 Guidelines for Preventing Cardiovascular Disease in Women emphasize eating fresh fruits, vegetables and lowfat milk and milk products.
Our campaign encourages people to include three servings of lowfat or fat free milk as part of a heart-healthy diet and to walk everyday. With nine essential nutrients, including calcium, vitamin A, vitamin D, protein and potassium, milk is a great way to get a nutrient boost.

Overweight Kids Lose Weight Eating Peanuts Every Day

High risk overweight adolescents, ages 10-15, can lose weight while substituting an ounce of peanuts or peanut butter for other less healthy snack choices.
The study, "Weight Loss in Overweight Mexican American Children: A Randomized Controlled Trial" describes the "Family Lifestyle and Overweight" (FLOW) Prevention Program, which is in a school setting. It is being conducted by Baylor College of Medicine and the United States Department of Agriculture- Agricultural Research Service (USDA/ARS) Children's Nutrition Research Center in Houston, Texas.
The study found that children often skipped school meals, only eating the low nutrient, high calorie, afternoon snacks often provided at the school. "We know that afternoon is one of the most vulnerable periods for weight management. To address this issue, we provided peanuts or peanut butter with a fruit or vegetable as a healthy, nutrient dense alternative", said Dr. John Foreyt, Director of the Behavioral Research Center at Baylor College of Medicine and principal investigator of the study.
This study is highly significant because it is one of the first to show that the highest risk minority group, Mexican-Americans, can successfully lose weight and improve blood lipids in a school-based intensive intervention program. This is an important feat considering 37 percent of Mexican-American children in the US are overweight and obese, which is even higher than the 34 percent of overweight children in the general population.
FLOW participants lost statistically significant amounts of weight at 3 months and were able to keep it off through 6 months, which is not often seen in weight loss programs. The intervention group also significantly reduced total and 'bad' LDL cholesterol levels at 6 months compared to the control group adolescents.
The FLOW program is addressing overall lifestyle by focusing on intervention sessions contained in three components: 1) nutrition education and behavior modification, 2) physical activity, and 3) food intervention during snack time in class. The adolescents participate in instructor led nutrition lessons in which worksheets are provided once a week for 12 weeks to help the kids set goals and understand how to establish regular eating times, select appropriate portions sizes, and choose nutrient-rich foods and snacks in place of foods with minimal nutritional quality. The kids also exercise 4 times per week via circuit training.
According to the paper, all of the children at the school received a snack during the school period when the food intervention was held, "although the intensive intervention children received peanuts/peanut butter with a fruit or vegetable to enhance satiety and to provide an opportunity for fruit/vegetable consumption." Traditional snacks, such as chips and snack cakes, were replaced in this group. Monthly parent meetings were also offered to build support with parents and families.
Peanuts and peanut butter were well liked by the participants. The peanut snacks helped the kids from overindulging on other unhealthy snacks. Previous studies have shown that eating peanuts helps you stay full longer than when eating high carbohydrate snacks.
Furthermore, the results are consistent with evidence in adults, which shows that regular consumption of peanuts, peanut butter, and peanut oil lowers total and "bad" LDL cholesterol and improves cardiovascular disease risk, and is helpful in weight loss and maintenance.
The Family Lifestyle Overweight Prevention Program suggests that providing a nutrient dense, satisfying healthy peanut snack daily in a school-based setting is part of an effective lifestyle plan for promoting initial weight loss in overweight high risk Mexican-American adolescents.

John Daly's Lap-Band Surgery and 115 Pound Weight Loss

John Daly entertained reporters this morning at an early morning news conference in Australia, where was getting in a practice round at the Hyatt Regency Golf Club, looking very slim. He has lost 115 pounds since undergoing adjustable gastric band surgery in February 2009.
The golfer states that his highest weight was between 280 and 300 pounds.
What encouraged him to change his eating and drinking habits to lose the weight? John Daly, known for being a golfing rebel, was suspended from the PGA tour for six months in December 2008. As part of an effort to get his life back in order, he underwent adjustable gastric band surgery, commonly called Lap-Band surgery after the first US FDA-approved device made by Allergan. However the band that John has is a newer product called the Realize Band made by Endo-Ethicon Surgery.
The adjustable gastric band is a silicone ring that is surgically put around the top of the stomach, forming a gastric “pouch”. Saline is injected through a port that is placed under the skin and fat tissue which constricts small balloons inside the band. The restriction provides for greater satiety with less food, resulting in a caloric deficit and weight loss.
Patients are encouraged to consume small, but nutrient dense meals after surgery. Sugar and fat are restricted to reduce calories. A common issue, however, is that foods must be soft or chewed very well to prevent a blockage at the site of the band. Unlike with Gastric Bypass, alcohol is not limited post-band, however it is highly discouraged because of its caloric content. Back in June, John Daly told ESPN reporters that he sips on beer once in a while, but hasn’t been drinking much since the surgery.
Daly has since returned to the European Tour, and has had some success. However, his swing coach feels that the power he once had for long drives is no longer there because of muscle mass loss, common in patients with a rapid weight loss. This past week, he finished tied for 28th at the Australian Open.
John Daly, who is 43 years old, joked with the crowd about his plans to write a book about his life that will be made into a movie. The most recent book about him is “John Daly, My Life In and Out of the Rough” was published in 2006.
When asked who he would like to portray him, he stated, “I just saw Matt Damon, how he swung a golf club, and I thought if I ever made a movie, I want him to be me. The tough part is who would play me at 290 pounds. Now Kevin James, he’s my bud, but he’d be good.”

Health Canada Advises To Avoid Certain Weight Loss Products

Health Canada is advising consumers not to use Karntien, Karntien Easy to Slim, Armstrong Natural Herbal Supplement, Enhanix New Extra Men’s Formula, Power 58 Extra and Platinum Power 58 Extra due to concerns about possible side-effects.
Product Description: Karntien and Karntien Easy to Slim are promoted for weight loss. The other four products – Armstrong Natural Herbal Supplement, Enhanix New Extra Men’s Formula, Power 58 Extra, and Platinum Power 58 Extra – are marketed for sexual enhancement and the treatment of erectile dysfunction.
Reason for Warning: The Hong Kong Department of Health warned consumers not to buy or use the six products listed above because they were found to contain undeclared pharmaceutical ingredients.
Karntien and Karntien Easy to Slim were adulterated with sibutramine and a compound that is similar in structure to sibutramine (N-desmethylsibutramine). Sibutramine is a prescription drug used in the treatment of obesity and should only be used under the supervision of a health care professional.
Armstrong Natural Herbal Supplement, Enhanix New Extra Men’s Formula, Power 58 Extra, and Platinum Power 58 Extra were adulterated with tadalafil or unapproved substances with structures similar to tadalafil and vardenafil.
Tadalafil and vardenafil are prescription drugs used for the treatment of erectile dysfunction, and should only be used under the supervision of a health care professional.
Possible Side-Effects: Unsupervised use of sibutramine may cause headaches, increased heart rate and blood pressure, chest pain and stroke.
Unsupervised use of tadalafil and vardenafil by patients with heart disease can result in serious cardiovascular side-effects such as sudden cardiac death, heart attack, stroke, hypertension, chest pain and abnormal heartbeat.
Use of tadalafil and vardenafil may also beassociated with other side-effects including temporary vision loss, seizure, prolonged erection, headache, flushing, nasal congestion and abdominal pain. Tadalafil and vardenafil should not be used by individuals taking any type of nitrate drug (e.g., nitroglycerine) due to the risk of developing potentially life-threatening low blood pressure.
