Weight Watchers (WW) is a weight loss company, operating in about 30 countries around the world. The chief products of this company are dieting plans and services to aid in weight loss.

The strength of this weight loss program is the optional support groups which meet regularly and help members attain their weight loss goals. The unique selling point of WW is not weight loss by dieting, but weight loss by a lifestyle change. They show their members the way to eating right. This program teaches its members to eat till they are satisfied, not until they are full.

At WW, two different programs are offered. The first is the Core Plan. When crash diets like Atkins and South beach diet became popular, WW introduced their own variant-the Core Plan. According to this plan, some food types are categorized as core. Members are encouraged to eat core foods, the only restriction being that they must eat until they are satisfied, not until they find themselves stuffed. Core foods include food items from all the food groups, such as fruits, vegetables, dairy, meat, and grains. Members are not completely prohibited from eating non-core food. They are just restricted to a certain quantity per week. This way the members don’t feel deprived.

The other program on offer is the Flex Plan. Under this program, each member is first evaluated for height, weight, age, and activity level. Depending upon the evaluation, the member is assigned a number of points that they can consume on any given day. If a member performs sufficient exercise, his points may be increased. This program basically quantifies the member’s calorie intake and his or her energy expense through the day. The point system is developed based on servings and the food family and also the exercises. Exercising enables the members to accumulate negative points. This program offers the members a great deal of flexibility. There is no specific type of food that members can’t eat. The goal for them is to stay in the total points allotted for the week. If they gorge on excessive food, they can counterbalance it by exercising more than their usual amount. If a member chooses not to exercise, then he or she must reduce the total number of points consumed. The slogan for this program is apt- Where no food is a sin!

Weight Watchers is a good program for people who want to lose weight and lead a healthy lifestyle. This is endorsed more than aptly by Sarah, the Duchess of York.

Does your body has excess of fat accumulating? Try phentermine which makes sure that you do proper weight loss.

If you need sight correction and wear glasses, practicing certain sports with continuous perfect vision can be a virtual nightmare. There is a large number of sports, like boxing, basketball, judo, football, soccer and track & field, where you need to combine an excellent vision with agility and speed. In these sports, glasses would simply be constantly hindering and holding you back, or even against the rules. In this case, you clearly need contact lenses. Lenses give you the sharp vision you need combined with excellent convenience, to help you keep focused on your sport. Very likely, you will forget that you wear them after less than five minutes.

Of course, there are reasons to choose lenses before glasses while practicing any sport. Lenses don’t get foggy or sweaty like glasses, and you won’t drop them while climbing, throwing, running, smashing, paddling or tackling. They’re just there.

Lenses are very easy to handle, and that many athletes choose to wear lenses only when practicing their sports is evidence of this. Contacts can be put in or removed quickly in the changing room, and need very little maintenance. With the large selection cheap contact contacts lenses on the market, your budget won’t stop you either.

In ergogenic aids and doping one must consider the tests and the testing procedures themselves. Science is based on probabilities, not absolutes. There is always a degree of error in the tests and testing procedures. Consider the following. Because there is always a degree of error, this means that there will always be false positives and false negatives. However, the IOC and its subsidiaries have released little or no data on its testing procedures dealing with athletes. Most of the published data on testing, particularly with anabolic steroids, have been carried out with small numbers of untrained non athletes. Thus, the exact degree of error is unknown. For the sake of argument, assume that the chance of a false positive is 0.0015%. This seems quite small; however, if 10,000 athletes were to be tested in a year, one might expect as many as 15 false­positive tests. In reality this means that, potentially; 15 athletes will be wrongly accused of violating the rules governing their sport. Furthermore, as of 1996 the degree of agreement among six IOC laboratories was not acceptable . Thus, the degree of error is not consistent between laboratories and the chance of a false positive may be greater in some laboratories. This clearly may exacerbate the problem.Certain drugs such as cocaine are not found naturally occurring in humans. Thus, detection of these substances is relatively easy. Many hormones, when used as ergogenic aids, are quite difficult to detect (e.g. growth hormone). Also, certain androgens have been recently shown to occur naturally (i.e., nandrolone); thus, cutoff limits for drug testing must be established.

Several problems arise from the testing of androgens. First consider testosterone (T). Because T is produced in relatively large amounts naturally, simply finding an amount that is somewhat over the average limits cannot be considered positive. Currently the test for the use of exogenous testosterone is the testosterone:epitestosterone ratio. In normal untrained adult humans the ratio of production is approximately 1:1. This ratio may be disturbed slightly by alcohol ingestion (especially in women), aging , physical activity, sexual activity, etc. The established ratio for testing positive is 6:1. The use of this ratio in drug testing is greatly complicated because there is evidence that at least 1 in 2000 (0.0005%) men are deficient in the enzyme(s) necessary for the production of epitestosterone this would suggest that their T:E ratio will be higher than 6:1. The likelihood of finding athletes with high T:E ratios is illustrated by the Swedish anti-doping program. As reported in 1996, 28 out of 8946 samples (0.3%) produced T:E ratios higher than 6; however, only one of these 28 samples was conclusively considered to be the result of exogenous testosterone use . This study not only points out the difficulty of determining whether exogenous testosterone was used, but also suggests that the actual incidence of naturally occurring high T:E ratios may be as high as 0.3% in athletes. Detection of exogenous testosterone use can be further complicated if the athlete simultaneously uses exogenous epitestosterone . Because it is difficult to determine the difference between natural and synthetic T using the T:E ratio, alternate or additional methods are being considered such as using a testosterone luteinizing hormone ratio. Another alternative is the use of carbon isotope ratios. Differences in the ratio of carbon isotopes are used to construct T synthetically and the ratio found in naturally occurring T. However, the isotope ratio method of determining these differences is not any more accurate than using the T:E ratio at present. Furthermore, the carbon isotope ratio (C12:C13) may be affected by diet .

Recently, the sporting world has been shocked by the number of positive doping tests for nandrolone. Included in these positive tests are several superstars of track and field including Linford Christie and Merlene Ottey. Nandrolone is typically injected in an oil base and is the primary anabolic agent, which has been avoided by athletes subject to drug tests because it is easily detected even months after injection . It has only been within the last 2-3 years that nandrolone has been shown conclusively to be a naturally occurring steroid and the IOC has adopted a doping positive cutoff of 2 ng/mL. It is interesting that many of the positive tests produced concentrations of only 8­12 ng/mL. This suggests several possibilities. First, the tests are becoming more sensitive (i.e., the IOC position) and the athletes were taking a banned substance. Second, the test doesn’t work and is showing false positives (i.e., the position of some athletes, coaches, and scientists). Third, the athletes were taking (legally purchased) over-the-counter food supplements that contained a substance which produces nandrolone or its metabolites unknown to them (i.e., the position of some athletes, coaches, and scientists). The stature and number of athletes being tested positive have raised questions about the validity of the tests, questions that have reached national government levels. To date (August 1999), the IOC has released little information on the testing program, which would allow independent verification of its testing procedures . Certainly, with the potential problems seen with drug testing (i.e., false positives), it is not difficult to legally challenge the veracity of such tests.
