The 500 Calorie Diet and HCG - What you need to know

There are hundreds of diets out there promising fast, easy results. Some of these diets are based on point systems while others focus on eating alot of one certain food that will help facilitate weight loss. Recently, we have been seeing more and more diets based on severe calorie restriction. These diets can have serious risks.

Very low calorie diets (VLCD), diets where the individual consumes under 800 calories a day, have been used to jump start weight loss for individuals with a high Body Mass Index (BMI). The Weight Control Info Network, part of the National Institute of Health, suggests that only those who are obese, with a BMI of 30 or more should consider using these diets (candidates need to also have a high body fat percentage), and then only under medical supervision. The goal of these diets is to help individuals lose weight rapidly while also adding physical activity and nutrition guidance. These programs typically last from 4-16 weeks with an average weight loss of 3-5 pounds a week.

The 500 calorie diet is a popular VLCD that is being promoted for its ability to help individuals drop weight fast without exercise. The human chorionic gonadotropin (HCG) hormone is being added to these diets as a proposed way to capitalize on the calorie deficiency. HCG is a hormone that supports the normal development of an egg in the woman’s ovary. It is often used as a fertility treatment for those who are trying to conceive.

Some companies claim that severely restricting caloric intake along with taking the HCG hormone tricks the body into thinking it is pregnant. Because it is not getting enough calories through food, it begins to feed off the body’s fat for nutrients and fuel. Others claim that the HCG makes the dieter feel fuller therefore helping them stay on the 500 calorie diet. According the the Mayo Clinic, there have been no studies that prove these claims. Facts and Comparisons states that HCG has no known effect on fat mobilization, appetite or sense of hunger, or body fat distribution.

VLCD can cause the individual to feel a loss of energy and be fatigued. Other less serious side effects include constipation, diarrhea, and nausea. Some people experience serious side effects such as gallstones when they drop weight quickly. Adding HCG injections to the restricted diet can cause a number of side effects including blood clots, headache, depression, irritability, swelling, and pain at the injection site. These diets are not suitable for children or teens and can also have an effect on pre-existing medical conditions.

For athletes, HCG is banned by all organizations under the peptide hormone and analogue class. This hormone will cause a positive drug test. The use of this hormone for weight loss is NOT recommended by the REC.

For anyone considering either diet option, there are a number of negatives to consider. First of all, rapid weight loss, such as 1-2 pounds a day, is not recommended. A more healthy and realistic goal is 1-2 pounds per week. In the long run, slow weight loss is more sustainable than is rapid weight loss. Also, research shows that those who limit their caloric intake to 400-800 calories a day gain back the weight they lost within six months. Severe dietary restriction is difficult to follow in the long term.

Diets such as these require constant monitoring as the reduction of calories makes the sources of the calories even more essential. The foods ingested must contain the needed vitamins and minerals along with a good ratio of carbohydrates, protein, and fat. Just randomly cutting calories can deprive the body of needed nutrients and fuels, especially for those who are also physically active.

Restriction can also affect metabolism in a negative way, putting the body into starvation mode and causing it to slow down its metabolism. This may also cause the body to eat away at the protein in lean muscle tissue to fuel its daily processes.

Before considering VLCD, consult your physician. There are plenty of other more sustainable and less risky ways to gain control over your weight. Next week, we will suggest strategies to help lose weight without severely cutting calories or using weight loss supplements.

The Effects of Alcohol on Athletic Performance

Many of us know that excessive amounts of alcohol can negatively impact our health. The dangers of liver deterioration, dementia and cancers of the mouth, throat and lungs have been stressed to us for most of our lives. Alcohol is toxic to the body and only provides empty calories. For collegiate, professional and recreational athletes, there is also a direct effect of alcohol consumption on performance, often for days after an episode of drinking. This includes not only competition, but effects on practice, strength training and conditioning sessions as well. Still many athletes do not understand the full effect it has on the body. In a survey conducted by the NCAA, over 60 % of student-athletes continue to believe that their use of alcoholic beverage has no effect on athletic performance or on their general health.

Negative Effects on Performance

Generally, alcohol does not increase performance in sports and it has many harmful effects associated with its use. The detrimental effects of alcohol on athletic performance are very well documented and include impairment of the following:

•Complex and fine motor skills
•Balance and steadiness
•Reaction time
•Memory and information processing
•Alters temperature regulation during prolonged exercise in the cold or heat
•Ability to get a good nights rest (Drinking excessively can cause you to toss and turn and wake up tired instead of well rested.)
•Drinking can also delay muscle recovery by reducing the production of growth hormone, testosterone and IGF.

Furthermore, its diuretic effect may lead to dehydration and depletion of key electrolytes (potassium and sodium) as well as minerals such as magnesium, potassium, calcium and zinc, that are vital to nerve and muscle coordination. For an athlete who drinks moderately heavy or heavily one night, dehydration can last a few days, especially since few athletes drink water between alcoholic beverages or drink enough the next day to make up for the water loss. When an individual drinks heavily and does not consume water or sports drinks, they have a good chance of developing a hangover. Hangovers often are characterized by nausea, headache, body ache pain and fatigue following a night or day of drinking. Athletes that experience hangovers have been known to perform poorly on tests, in practice or games, or even injure themselves.

Potential negative Effects on Life

Drinking lowers inhibitions. Decision making is impaired and can cause you to engage in behaviors that you may not do sober, including:

•Beer Pong and other drinking games
•Strip Poker
•Driving while intoxicated
•Going home with a total stranger
•Having unprotected sex
•Fighting (this includes friend and family members)
•Theft

Some of these can lead to injury (physical and mental), jail, hospitalization and death.

Alcohol and its effect on other nutrients

Alcoholic beverages are high in calories, anywhere from 80-800 calories per drink, calories that you may not consume otherwise. Also, alcohol may promote fat storage in the body as the body stores harmless fat and burns the alcohol as fuel. This can lead to a “beer belly”. After a night of drinking, many people choose to eat high fat foods to excess causing weight gain. Excess fat weight can slow down an athlete.

Alcohol does not contain proteins, vitamins or minerals and it may actually interfere with the absorption of key vital nutrients such as folic acid, zinc and thiamin. These nutrients are involved in the metabolism of fat, proteins and the formation of hemoglobin. The lack of these vitamins can lower energy and oxygen carrying capacity and thus negatively affect endurance sports.

Be responsible

Everyone responds differently to alcohol based on gender, body weight and metabolism. So keep in mind that a 6’4” 325 lb. offensive lineman who drinks regularly, more than likely will drink more than the 5’4” 137 lb. sprinter who drinks occasionally. Don’t be pressured into drinking contests with peers your same size and age, other factors must be accounted for.

Develop rules for yourself inside and outside of competition. For example, choose not to drink in season and always limit the amount consumed in one sitting. Try alternating alcoholic beverages with water when you are out with friends. Don’t drink on an empty stomach and plan out snacks or meals ahead of time to avoid eating high fat foods later on. Refrain from participating in drinking games that increase the speed and amount of drinks you consume.

Being aware of how alcohol affects your performance can help you make informed choices on if and when to drink. The next time you plan on going out, think back to two-a-days, summer workouts, the goals you set for the season, and your teammates.

Once you’ve done that take these facts to the bar:

•Consuming 5 or more alcoholic beverages in one night will affect brain and body activities for up to 3 days.
•Two consecutive nights of binge drinking will affect brain and body activities for up to 5 days.
