Why Athletes Should Not Be In A Low-Carb Diet
In the matter of should we approach a low carb diet or not the opinions are divided. One claim in favor of low carb diets is that humans did not evolve to eat modern food based on grains, starches, or refined sugar.
This type of alimentation determine the body to produce excess amounts of the hormone insulin therefore the body stores rather than burn fat causing obesity and heart disease, cancer or diabetes.
Nutritionists in favor of low carb diet claim that humans evolved eating mainly meat and the current world wide problem of obesity is due to the assumption that the low-fat approach is healthier. They also claim that people have been encouraged to eat more carbohydrates, which stimulate appetite and more eating causing overweight.
Nutritionists try to prove scientifically that low carb diets can successfully be used to lose weight effective and safe. The test period was short and they were not able to prove the long-term health effects of the diet.
A study was performed in 1965 in California at Naval Hospital from Oakland. The dieters had to use a diet of 1000 calories daily, high in fat but limiting carbohydrates to 10 grams each day. The group that maintained this diet over ten days lost more body fat than did the group that finished the program earlier. Defenders of low-carb diet called this experiment the metabolic advantage of such diet.
Some differences between low-carb diets are always present. These diets are being recognized by their proportion of carbohydrates intake they advice us to eat, and the methods used in determining which ones should or shouldn’t be consumed. As a general agreement, sugar must be eliminated, but when talking about levels of grain, fruits or vegetables, the opinions are divided. This is rather confusing because it is also a general agreement that fruits are not so good as vegetables and grains as fruits.
Side effects are also present on low-carb diets.
Very low carbohydrates consumption can lower the metabolism and drive it through ketosis, resulting headaches, nausea, tiredness, dehydration, dizziness and some unusual sweet smelling breath.
Another side effect is that if diets replace calories from carbohydrates with meat, high consumption of fat and cholesterol will occur, thus increasing the risk of heart diseases. Even more, it was hypothesized that a change in blood acidity can lead to bone loss and that kidneys can become overworked. However these kidney or bone loss side effects had not yet been proven.
Why low carb diets don't provide enough energy for athletes?
Generally, while low-carb diets may help usual people to lose some weight, they aren’t recommended for athletes. They must get enough energy needed for their activities, and whether their body uses fat, protein or carbohydrates as fuel for exercises depends upon its intensity and duration.
Normal people don’t need high-carb diets because without an intensive psychical activity that is permanently kept they will gain weight.
Athletes need these diets instead of low-carb ones because they consume all what these diets bring, and maybe much more, so they need to eat a lot of proteins, vitamins, and even fat, in order to have a perfect and healthy body that can withstand the intense workout.
Specific high-carb diets are used on each athlete because everyone has its specific metabolism, and so a specific anabolism that has to be equaled by the catabolism. Each sport needs different types of body construction so athletes will chose their diets accordingly. A 10 Km runner will chose that its body must be always as slim as possible, no fat at all is required, and a specific diet to ensure he’s up to run 10 km without having any weight problems. Others like a 100 m runner must have full high-carb diet, and iron muscles, in order to accelerate as fast as possible.
Concluding each athlete must be aware that in order to achieve performance, they first must have a body that fits their desired sport and that is where diets come in. A perfect and healthy body will surely make the difference between athletes as well as the training.
Low-carb diets are not indicated for performance athletes because they do not provide the necessary quantity of vitamins, proteins and other chemical compounds that athletes need to consume during the intense training.
