Haute Fitness: Low Carb Diets are No Good for Athletes

Please tell us why this is or is not bullshit:

http://hautefitness.blogspot.com/2009/12/low-carb-diets-are-no-good-for-athletes.html

>When I hear an individual rave about weight loss achieved through one of the many low-carb diets currently the rage (i.e. Atkins, South Beach, Zone), I want to know these three things:

>How long has he/she kept the weight off?
How is he/she feeling?
Is he/she able to maintain a steady and intense exercise regimen?

>I bet the answers are “a few months,” “ok” and “he/she doesn’t really work out all that much." While a moderately active individual may achieve some success on one of these plans, these low-carb diets are completely unsuitable and unsafe for athletes.

Let’s start with my favorite diet-to-hate, Atkins. Atkins claims on it’s website that it’s effective because the plan puts the body into a state of ketosis by severely restricting the intake of calories from carbohydrates. Purposely inducing a state of ketosis, unless you’re a diabetic or suffer from epilepsy and are under direct medical supervision, is ridiculous, unhealthy and dangerous. Side effects of ketosis resulting from low-carb diets, not just Atkins include “temporary dizziness, headache, lethargy, weakness, diarrhea and nausea. In addition, a person on a diet extremely low in carbohydrates, fiber, and many vitamins and minerals is liable to feel cranky, sluggish, and deprived.” This is especially true for lean individuals … Athletes! How can an athlete give his/her all in a game or workout under these conditions?

Quoted By:

Ketosis occurs when the amount of carbohydrate fuel- the fuel that is needed to run the body - drops below a critical level, forcing the body to turn first to protein (yes, this means muscle) and then to fat reserves to do the work carbohydrates normally do. When protein is deflected in this manner, excess nitrogen is released and places a burden on the kidneys. When fat is likewise deflected, the breakup releases fatty acids, or ketones, into the bloodstream, further burdening the kidneys. If ketosis continues for long periods of time, serious damage to the liver and kidneys can occur.

Quoted By:

In addition to purposely straining the kidneys and the liver, the Atkins diet, in its initial stages (about two weeks) restricts carbohydrate intake to 20g. How many calories is twenty grams of carbs? 180calories. While Atkins doesn’t limit the amount of total daily calories one may consume, it does limit the amount of calories coming from carbohydrates, the basic source of fuel for the body. Let’s say we have a 250lb male football player. His daily caloric needs during the season are 5500 calories/day. This means that 5,320 of his calories now have to come from protein and fat. Even if 70% of the remainder of his caloric intake comes from lean protein, which is unlikely, 30%, or 177g of fat are being consumed on a daily basis. That’s eating a pound of fat every 2.5 days. Under no circumstance is this healthy or appetizing.

The Zone Diet, while it doesn’t specify a quantitative limit on the number of daily carb grams, does limit total caloric intake as many diets do. The Facts About Fitness web site, makes a calculation that a hypothetical athlete, a baseball player let’s say, who weights 180 pounds should have 2106 calories daily on Zone Diet. An active 180lb male should be eating approximately 3900 calories/day, 3400 calories if dieting! The Zone diet also sets calorie limits for meals and snacks to 500 calories and 100 calories respectively. So while following the Zone Diet, this player should gear up for the big game with 3 rice cakes or a small apple. Would you bet on a win for his team? Not only are the calories restricted in the Zone, but also so are the percentages of calories coming from carbohydrates. In fact, since rice cakes have too many calories coming from carbohydrates, he could not eat 3 rice cakes as a pre-game snack. He could have one rice cake and half an apple.

Quoted By:

While on a low-carb diet, whether it be the Zone, South Beach (similar to Atkins though more liberal in the allowance of vegetable servings) , or Atkins, glycogen stores, the main source of fuel for athletes are depleted. You know what else becomes depleted along with these energy stores? Water. With the depletion of each ounce of carbs stored as glycogen in the body, you lose about three ounces of water. Athletes show a decrease in performance when as little as a 4% reduction in body water content. Imagine a team of football players running the field on a low-carb diet. They’d play worse than the Redskins (if possible)!

Of course people will lose weight on low-carb diets! They restrict calories and dehydrate the body of the one element needed for survival … water. They also increase the rate at which fatigue sets in, cause dizziness, headache, lethargy, weakness, diarrhea, nausea, lead to muscle-wasting, and ignore the benefits of a diet rich in fruits and vegetables. While some individuals may choose to risk all these things to lose a few pounds, no competitor, no athlete should.
