Members don't see this ad.

Q) A 27 year old MMA fighter had 10 egg whites, grilled chicken and a glass of Whey protein isolate shake. Which of the following would most likely be observed in his postprandial blood profile?

A. Increased Insulin, Decreased Glucagon, Decreased GIP
B. Increased Insulin, Decreased Glucagon, Increased GIP
C. Increased Insulin, Increased Glucagon, Decreased GIP
D. Increased Insulin, Increased Glucagon, Increased GIP
E. Decreased Insulin, Decreased Glucagon, Decreased GIP
F. Decreased Insulin, Increased Glucagon, Decreased GIP
G. Decreased Insulin, Decreased Glucagon, Increased GIP
H. Decreased Insulin, Increased Glucagon, Increased GIP

Its pretty confusing, so think carefully.......

P.S.-I wrote this Question

F
proteins only no glucose--> glucagon release--> inhibitory to insulin and GLIP(fxn incr insulin decrease glucagon) sooo its decreased as well?????
"hand waving"

I'm interested to see this answer lol

correct me if i'm wrong, but doesn't glucagon STIMULATE insulin release? I thought it was:
Insulin inhibits glucagon..
glucagon stimulates insulin

ahh good point
--- glucagon--> glycogenolysis --> free glucose needs the insulin to be taken upp?
is that the concept??

I think it's primary hormonal regulation. But I'm sure the free glucose level contributes also.

I protein intake stimulates both insulin and glucagon secretion. Since this is right after a meal, GIP, an incretin, should be elevated to slow down gastric motility and promote satiety.

My answer would be D. Not sure about the last part in the statement above.

This kinda reminds me of when classmates try pimping me with their own ridiculous fake questions that make no sense only to make themselves feel better when I get it wrong lolol

Yep......That's exactly what I'm trying to do..........

*************High Protein meal**********************
GIP is elevated in response to carbs, fats and protein.

Regarding Insulin...........Amino acids have an equally same effect on Insulin rise as glucose does. So there would be a large rise in Insulin to handle the large rise in amino acids( Insulin would be responsible for building muscle by utilizing these AA's, cause it has an ANABOLIC action)

BUT......there is little, if not any carbs in this meal...so consequently there would be hypoglycemia due to Insulin......
So counter act this hypoglycemia, Glucagon levels rise.
(Glucagon would then increase gluconeogenesis to elevate blood glucose)

Q. How do Glucagon levels rise ???
A. By two mechanisms....
1) In response to a high protein meal, CCK is released (remember CCK release is stimulated by both fats and proteins). This CCK "alerts" Alpha cells to an incoming rush of amino acids into the bloodstream, thereby increasing Glucagon secretion.
2) Amino acids, especially ARGININE, directly stimulate Glucagon release.

Hope this helps..............🙂

and this is NOT a fake question.......
