The notion that artificial sweeteners (and sweet tastes in general) might produce an insulin response is one of those murky memes that winds itself around the blogs, but it’s never stated one way or the other with any sort of confidence. I briefly mentioned the possibility of non-caloric sweeteners influencing satiety hormones in last week’s diet soda post, and a number of you guys mentioned the same thing. Still, I’ve never seen unequivocal evidence that this is the case.
This whole idea first came to my attention some time ago when my dog Buddha got into a bottle of “alternative sleep assists” which contained, among other things, 5 HTP (version of l-tryptophan) and xylitol (sugar alcohol). Long story short, dogs can’t take xylitol because it causes a spike in insulin, which then severely depletes blood glucose. Buddha got past this with a trip to the vet’s at 10:30 Sunday night (thanks, Dr. Dean). But it occurred to me that the same effect might be seen in humans, which is why I pose the question today…
Do artificial sweeteners induce insulin secretion (perhaps via cephalic phase insulin release, which is sort of the body’s preemptive strike against foods that will require insulin to deal with)?
Before I begin, I want to make something clear: this is not your standard definitive guide to whatever. I’d like to be able to issue a proclamation regarding diet soda that stands the test of time immemorial, but I cannot. Research is still in its infancy, and exactly what diet soda does to those who drink it – if anything – is incredibly confusing. The one thing I can say with any certainty is that, while it’s unfair to say it will kill you or give your unborn child prenatal tumors or make you impossibly obese, you’re probably better off without diet soda. It tastes weird, the list of unpronounceable ingredients is too long for my comfort level, and I’ve seen one too many unsuccessful dieters that seem to live on the stuff.
There are two things to consider when making any conclusions about diet soda’s place in a healthy diet. Do the ingredients used in diet soda pose a threat to your short-term or long-term (or that of your offspring’s) health? Is it a kind of sugary methadone, impeding healthy eating by making it harder to kick the desire for sweet things in your mouth because, well, you’re constantly putting things in your mouth that mimic sugar? Let’s dig in.
It’s probably the biggest thing that makes some people hesitate in going Primal. Sure, they appreciate the logic and sensibility of the Blueprint lifestyle. They value the chance to improve their health and effectively lose weight. They love the idea of having more energy. They salivate over the prospect of bacon. But then comes the proverbial wrench in the plan. “What about bread?” they ask. (Sometimes it’s diet soda, pasta, pancakes, pizza, Skittles, etc.; I’ve heard it all.) Against all powers of wisdom, self-interest, and rationality, how is it these isolated, deeply entrenched cravings hold such sway over our lifestyles – and diet decisions? Is a baguette really so enticing that it determines a person’s willingness to live a healthier, more vigorous existence? Is the de-grained life really not worth living?
It’s a common refrain I hear: “Oh, I’d love to go Primal, but I just couldn’t give up my breakfast cereal.” Okay. It’s got me thinking lately: what is it about the psychological power of (non-Primal) favorite foods?
Most folks who decide to give the Primal Blueprint 30-Day Challenge the old college try do so to correct an underlying health issue. Maybe their cardiologist’s recommended dietary plan hasn’t been improving their lipid numbers as promised, or perhaps they’re sick of fighting a losing battle with diabetes by submitting to a daily pharmaceutical cocktail that appears increasingly ineffective. Gentle (or not so gentle) prodding from coworkers and loved ones with incredible results is another common motivating factor. But, above all, most people get involved with this Primal stuff because they want to lose weight without stressing over calorie counts, fat grams, and endless hours on the treadmill. And in order to do that – in order to lean out effortlessly and maintain that leanness – it’s vitally important that you dial in your carb count.
I’m a big guy (okay, obese, if I’m being honest) who’s getting smaller fast. I adopted the PB a couple weeks ago, and I’ve already dropped twenty pounds, going from 300 to 280. Don’t get me wrong, I’m not complaining. I’m just confused. How does that work? You always hear that initial weight loss for the really overweight is fast, but why? Is it really just water weight? It seems metabolically impossible that I’ve actually burned that much body fat… I can’t help but feel a bit let down if all I’m doing is losing water. If there’s one thing I learned from your writings, it’s weight isn’t just weight (and calories aren’t just calories). So… what gives?
