raises insulin as do all foods
i'm a fanatical diet logger and one thing i've learned at least with myself is these diet bars will definitely raise my insulin levels by about 10-15 points for about 2 hours before my glucose levels drop back to ketosis levels... i've tried the atkins bars, those bars that taste like french toast (i really like those), and the myoplex ones (i have cases of those). here is what i've figured out though.....
regardless of what i eat, my insulin will rise (evidenced by rising glucose levels). I can eat pork (like i ate an hour ago) and my glucose rose from 89 to 105 and will stay there for about an hour or so before going back down. so for me, i know my glucose levels will rise with everything, including lard (i tested myself one day just to satisfy scientific curiosity and my glucose rose about 5 points). with that in mind, i realized that sweet tasting things will also raise my insulin regardless of sugar content, but here is the interesting difference:
1. a snickers bar will raise my glucose 20 points for 2.5 hours before glucose level returns to keto levels (85mg/dl for me)
2. a sugar-free (aspartame) soda will raise my glucose levels 15 points for 1 hour before glucose returns to keto levels.
3. strong coffee (one packet of splenda, but coffee is still strong and doesn't taste sweet to me) will only raise my glucose 12 or so points
4. an atkins bar, myoplex bar, or other bars will raise my glucose levels 10-15 points for about 2 hours before my glucose returns to keto baseline.
5. meat (chicken, pork, beef) will raise my glucose levels 5-12 points for 1-2 hours depending on how fatty it is and how hard the meat is (jerky is least affecting).
my conclusion?
1. sweet tasting things seem to elicit glucose release in much the same way as sugar does. the only difference is that since i don't have sugar (it just tastes sweet), my body drops back to keto levels quicker than when it deals with sugar
2. something else i didn't include... if in severely starving myself (below 1400 cals), my glucose levels seem to move less (the same snickers bar only raises me 10 points and doesn't last more than an hour, probably due to the starvation and resulting high absorption)...
keep in mind, everybody's physiology is different, because as you can tell, i go into ketosis (ketonemia) at 85mg/dl , and others must dip to less than 70 (although this is more a result of the fact my body is extremely efficient at recovering glucose, and is not an indicator that i have it easier than others... quite the opposite, it's harder than hell for me to get there)
