Yes, that's exactly why Gatorade and other sports drink reduced the calories in some of their drinks.
/sarcasm.

There is a very good reason why most of the sports nutrition companies have REDUCED the calories per ml. It has been demonstrated in numerous studies that calories taken in liquid form (including gu's) create an overload of sugars in the small intestine, requiring the body to pull water from the blood serum to create proper balance, ultimately resulting in severe dehydration, regardless of how much water you drink, and also ultimately resulting in a complete shutdown of the small intestine, meaning NO nutritional absorption. The ONLY way to avoid this is to take your calories in a natural form (solid), which allows a proper regulation of needed calories. The reason for the 20 ish calories per 8 oz of water is for fluid absorption, NOT calorie replacement. Once again, pay attention to current science and it has been well established that this small carb load improves water absorption without disrupting the small intestine process.
Last comment on this thread topic. Salt??? Really? Anyone doing an Ironman should have at least a basic enough understanding of human physiology to understand that if you are sweating your sodium serum level is going UP, not down, and the only thing that can create a low sodium serum level is drinking TOO MUCH fluid, with or without sodium. The amount of sodium as a low normal in a human is 135 mmol/l, with converts to roughly 52 GRAMS per liter. It will not make a significant difference to your sodium serum level if you are drinking plain water or consuming even 1 to 2 grams of sodium per hour. I have avoided added sodium in all of my diet for over 3 years, and in that time completed numerous ironman and 70.3 races, and an ultraman and the furnace 508 cycling race, done well enough to set AG records, and have not had 1 cramp since stopping the excess sodium. This admit tingly has less to do with the sodium reduction, and more to do with recognizing the futility of expecting sodium to reduce cramping, and shifting my attention to the real causes, such as muscle imbalances (quite common with endurance athletes) and lack of a proper strength training program. In summary, no Gatoraide? Who cares? Drink water, eat solid food that you like, and have a great race 😃
