Low Carb and Vomiting...

[cozmokramer]

please read and respond...

Lets say that someone is on a low carb diet and in ketosis...

then this person eats a large meal (tons of carbs) and then
vomits (they are bulemic) right after eating...

so they were in ketosis and then they spiked their insulin level
because of this meal full of carbs... but now all of a sudden with
high insulin levels they don't have any carbs in them...

is this good, bad or what...? will they remain in ketosis... will
they fall out but get back in easier or what?

I did a search on the speed of carbohydrate conversion and, as I expected, came up with alot about glycemic indices and such. The absorbsion would seem to me depend on how long it was from the first swallow of the carbs (and the GI value of the carbs) to the vomitting. I would assume that some carbs were absorbed, which would lead one out of ketosis, but I don't know how the volume of carbs at one sitting would effect the amount of time the body would take to get back in ketosis.

Also, I have no idea as to the effect of the perhaps increased production of bile from the vomitting would effect this situation. Curious to hear what others say.

This is really only a guess from me so don't take it as a fact of any kind.

It depends entirely on how many carbs are absorbed before the person chucks. The insulin response is to the ABSORBED carbs, not the carbs that go down your throat. So if very little carbs were absorbed, then the person would remain in ketosis. If a lot of carbs were absorbed, then ketosis would be lost. If they absorbed enough carbs to spike insulin, then those carbs are still there after they vomit, and the insulin will do it's job as normal. In other words your body distinguishes between carbs ingested versus carbs absorbed into the blood stream (which is where insulin response, ketones, etc... are affected).

I hope you're not getting any crazy ideas.

Dieting and throwing up

In the ketogenic diet, your body eventually gets used to being deprived of carbs. So basically your body uses fat and ketones for energy. Think about the body. It's nature is to adapt. If you remain a lazy slug, you'll be used to being lazy. If you get into the habit of working out regularly, you're body will feed for that. My bro comes home every weekend and he works out 5 days a week. The 2 days at home drives him nuts. He can't stand being inside the house for very long. So he often goes running and lifts. Anyways what I mean is your body adapts to a lot things. Especially things that you eat. When you deprieve you body of carbs for a period of time and then eat a whole bunch of carbs in a day, you'll get sick. This happens to people who fast. People will fast for 3-10 days, depending how long the fast is and then after the fast ends they pig out. They always get sick. You want to ease back into eating the foods that you deprive yourself of. If you must eat carbs, eat them in very small amounts and be sure they're not simple sugars. I've followed the anabolic diet once. For 5 days you limit yourself to no more than 15 grams daily and then 2 days you load up on carbs in order to restore muscle glycogen. I felt sick during those days.

USMC....

thanks for the response... BUT it doesn't answer the original
question that was posted here... duh...

Quesiton Was Already Answered

True, I did not answer your question. I was just stating what causes vomitting. Your quesiton was already answered by others.....duh

MS is right, insulin is secreted in response to blood sugar. I don't think your gonna boot any of that out (unless you get nosebleeds in the process)

By the way, what's up with your hypothetical question? I don't think vomiting has ever been part of a succesful healthy diet.
