But for now, the subject is artifical sweetener, from here on referred to solely as Splenda, my sweetener of choice. I'm going to stick to beverages here, as that is the only form in which I consume Splenda.
Basically, there is an argument going out there that Splenda can make you fatter, less healthy, etc. Supposedly, your brain is tricked into thinking that you're drinking something sweet, but when it doesn't get actual sweetness in your digestive system, it makes you crave something sweet.
This doesn't make sense to me, but I am open to hearing explanations. My take on it is thus: if your brain continuously gets signals that you are drinking something sweet, but nothing sweet ends up in your stomach, eventually your body habituates and figures out that tasting something sweet does not mean it needs to produce insulin. In effect, I have rendered my "sweet" taste buds obsolete in the digestive process through habituation. Diet drinks do not make me hungrier, or crave any sort of food. My body, I believe, treats them like carbonated water. I drink it and piss it out, and that's the end of that. But I've been drinking diet sodas for a very long time and using splenda in my coffee for years.
The problem, I think, is with suddenly switching from regular soda to diet or vice versa. I believe that if I suddenly started consuming sugar in my beverages, I would gain weight very quickly because my body is not used to getting liquid calories. But this belief that splenda can make you fatter - I'm not sure I'm buying it. Not unless someone can provide me with some evidence.
If a calorie deficit = weight loss, then I don't see how drinking diet beverages could negatively impact weight loss results. If it makes you crave sweets, but you don't eat those sweets, then where is the negative impact?
I'm not saying the opposite argument is wrong, I am just looking to understand the logic and science behind it. Thoughts?
