If that were true, how it is that vegetarians, who eat a diet that is even higher in carbohydrates than standard American diet is, tend to have lower body mass index, rather than higher? If carbohydrates make us hungry and overeat, we would expect vegetarians, as people who follow an exceptionally high-carbohydrate diet, to tend to be overweight. But that is not the case.
And even if that were true, what is the alternative? A low-carbohydrate diet is linked to kidney problems in humans, so it is not really an option.

My question is not how your liver and kidneys convert some amino-acids into glucose. My question is what would trigger gluconeogenesis after a high-protein meal (to cause a spike in your blood glucose levels, as she claimed happens). Gluconeogenesis is not happening all the time. Your liver has to think (rightly or wrongly) that blood glucose levels are too low for gluconeogenesis to happen. Why exactly would your liver be mistaken ablut your blood glucose levels after a high-protein meal?
Similarly, cholesterol production is not happening all the time, but only when your liver thinks (rightly or wrongly) that there is not enough fat in the blood. Methionine causes your liver to think fat in the blood is too low, so the liver raises your cholesterol levels after you have eaten something high in methionine. Which is why sesame seeds are not recommended to people with high cholesterol. Is there an amino-acid that causes your liver to think your blood sugar is too low, just like methionine makes it think fat is too low? If so, which one is it?
