Do artificial sweeteners cause changes insuline levels?
I believe that I have heard that aspartame does but saccharine and sucrulase do not, but I don't know.
Anyone got some advice? Thanks

Aspartame and its constituent amino acids: effects on prolactin, cortisol, growth hormone, insulin, and glucose in normal humans.

Because large doses of phenylalanine stimulate prolactin secretion in man, we studied the acute effects of oral doses of aspartame (0.534 g, equivalent to the amount of aspartame in approximately 1 L beverage), aspartic acid (0.242 g), and phenylalanine (0.3 and 1.0 g) on serum prolactin and other hormones in normal humans. Prolactin was not stimulated by any of the aspartame meals, aspartic acid, or 0.3 g phenylalanine; a small rise in serum prolactin, similar to that produced by a high-protein mixed meal, followed ingestion of 1.0 g phenylalanine. Serum growth hormone showed no statistically significant changes in response to any of the experimental meals whereas cortisol and insulin fell slightly and glucose rose slightly during each of the meals. We conclude that these doses of aspartame do not alter secretion of prolactin, cortisol, growth hormone, or insulin in normal individuals
Response to single dose of aspartame or saccharin by NIDDM patients.

Twelve normal subjects and 10 subjects with non-insulin-dependent diabetes mellitus were given, in random order at intervals of greater than or equal to 1 wk, three drinks of the same beverage: one unsweetened, one sweetened with 400 mg aspartame, and one sweetened with 135 mg saccharin. The amount of sweetener approximated that in 1 L of sugar-free soft drink. Plasma glucose, insulin, and glucagon were measured for 3 h after ingestion of the test beverage. Plasma glucose declined slightly throughout the test period, probably due to fasting, with no differences between the three treatments. Neither sweetener affected peak insulin levels in subjects with or without diabetes. Analysis of area under the curve showed that mean insulin levels were statistically significantly higher after aspartame than after saccharin or unsweetened beverage in normal subjects only, but the magnitude of the difference was small and unlikely to be of physiological importance in the absence of differences in glucose levels. Furthermore, the differences could largely be accounted for by a decrease in insulin values after both unsweetened beverage and saccharin, with no change from baseline after aspartame. Glucagon levels showed time-to-time variation but no overall differences. We conclude that ingestion of aspartame- or saccharin-sweetened beverages by fasting subjects, with or without diabetes, did not affect blood glucose homeostasis.

OBJECTIVE: To examine the effect of a single high oral dose of the novel noncaloric sweetener sucralose on short-term glucose homeostasis in patients with IDDM or NIDDM. RESEARCH DESIGN AND METHODS: A total of 13 IDDM and 13 NIDDM patients with glycosylated hemoglobin levels < 10% completed this double-blind cross-over study. After an overnight fast, patients were administered opaque capsules containing either 1,000 mg sucralose or cellulose placebo, followed by a standardized 360-kcal liquid breakfast. Plasma glucose and serum C-peptide levels were measured over the next 4 h. RESULTS: Regardless of the type of diabetes, areas under the curves for changes of plasma glucose and serum C-peptide levels after sucralose administration were not significantly different from those after placebo. During test meals with sucralose, one episode of symptomatic hypoglycemia occurred in each of three IDDM patients, but these episodes were not considered the result of sucralose administration. CONCLUSIONS: The present results support the conclusion that sucralose consumption does not adversely affect short-term blood glucose control in patients with diabetes.

Sweet stuff can induce a cephalic insulin response.
Basically, if sweet stuff stimulates your taste receptors, your body expects to recieve carbs and so gets ready to clear blood sugar.
Not sure to what degree though. I wouldn't worry about it too much myself. Do a google search of "cephalic insulin response" and see what comes up.
