Subject: Low Carb Soda? Part 1

Carbohydrate content and other factors should be considered when consuming diet drinks as well. Sodas are carbonated beverages. A byproduct of oxidative energy production is CO2 carbon dioxide. CO2 is eliminated through normal cardiovascular processes, however during intense exercise CO2 buildup may occur and you do NOT want to add additional CO2 gas from carbonated drinks. In addition, carbonation may interfere with hormone production as well as cause dehydration.
Sodas contain artificial sweetners. Artificial sweeteners cause the brain to react to sweet taste (cephalic phase response) by preparing the liver to receive a new supply of sugar. And if no sugar appears, the liver signals an urge to eat, or possibly over-eat.

In addition soda has caffeine. As you already know, caffeine is a drug that is frequently used all over the world, usually for its stimulant effects. Caffeine increases alertness, lowers the perceived exertion of exercise and decreases reaction time.

Caffeine does have side effects as well. At high doses (more than 15 mg/kg body weight), caffeine can produce slowed heart rate, hypertension, nervousness, irritability, insomnia, and gastrointestinal distress. In addition to this, it is a diuretic that blocks the release of antidiuretic hormone. This causes the kidneys to excrete more fluid than normal, which can dehydrate the body.

Irrespective of the possible adverse effects of sodas on weight control, no one disputes the lack of nutrition in these soda. Typically, sodas sole contribution to dietary and nutritional requirements is a little sodium.
