During my P90X postings last year I don't think I ever got around to discussing Recovery Formula. The last few weeks I've received numerous emails asking if we could replace the sugar in RF with stevia. This, I can only imagine, has come about with the marketing hoopla over no calorie sports drinks. I blogged a while back on "the world's most inane beverage" when I discovered that Gatorade was making a "low sodium" electrolyte drink. Since sodium is your primary electrolyte, I posed the question what could be more ridiculous? And they've answered; a sports drink with no energy. Amazing.
A quick lesson: calorie is a word we use for energy in the foods we consume. When we exercise we greatly increase the amount of energy (and electrolytes) we burn. Sports drinks were designed to replace things depleted while doing sports, which are primarily calories and electrolytes.
Marketers don't care about such pesky details. They are aware that people like new things, whether or not these things make sense. People like words like "no calories" and "no sodium" and, apparently, will buy them even if their goal is to buy something with calories and sodium.
Recovery Formula, as the name suggests, is designed to aid in recovery from exercise. This requires calories, among other things. I've written an article that discusses this process in laymen terms, and here it is.
