i so confused. is phenylalanine good or bad?

It generally isn't. Some people don't have the ability to metabolize phenylalanine, and it will slowly poison them. However, if this is you, you would definitely know.

So if your PA level is constantly high because of drinking Diet Coke, then you will poison yourself too?

I found out that when I stop drinking Diet Coke, I get depression symptoms. (Reproduced three times now). It must have something to do with the aspartame in it. When I take DLPA pills (a breakdown product of aspartame), the depression goes away quite fast. Drinking a can or two of Diet Coke also does the trick.

You sure it’s not just the caffeine? Caffeine withdrawal symptoms includes depression and a host of related symptoms.

Back in the dot-com days, thanks to employer-subsidized soda fridges, I was drinking easily 6+ cans of diet soda a day (in my case, Diet Dr. Pepper). Along with other startup related behaviors like eating fast food (Carl's Jr, what's up?) and not exercising, my weight increased to around 220 lbs on a 6'1" frame. I stopped drinking diet soda around the time I joined a weight-loss startup in 2011, and started eating healthier and I end up dropping down to around 175 lbs, which I more or less maintain to this day. I personally think "diet soda", even though "0 calories" doesn't do anything great for your metabolism or weight and is a great oxymoron of a product.

I suspect this is to try to quantitatively match the stimulant effect of caffiene plus sugar/HFCS in the sweetened alternatives.

Am I the only one that experiences sugar as a depressant? Eating high glycemic index foods makes me lethargic and sleepy. I've never experienced a "sugar high". I also don't have diabetes as my blood sugar level is within norm during routine physicals.

That sounds like insulin resistance, not diabetes.

It is probably just overload for you - I get the same thing after a big big meal or a lot of sugar. But a small amount is another story. If you drank the original size of coke (which I think was 8 ounces?) you might have another reaction!

Biggest advantage over regular coke: does not get sticky when you spill it.

Stains from diet soda are also way easier to completely clean up due to the lack of sugar! I've seen Diet Coke/Coke Zero stains vanish from light-colored clothing within minutes.

They really do, but if you power a couple down in substitute for lunch and aren't tempted to snack, then it can be an OK thing to do.

They should be used as a supplement and not a substitute.

Eh. If you want to slightly lower your caloric intake, and you normally eat a 700 calorie lunch... replacing that with 350 calories of protein shake a few times per week and still eating a healthy dinner, etc, is reasonable.

It sounds like you’re confusing the effects of eating unhealthy food with the effects of drinking soda

> More concretely, phenylalanine is in all sorts of foods like eggs, chicken, milk, soybeans, and breast milk. Remember how phenylalanine is an essential amino acid? And remember how you’re reading this right now and not dead? From these facts, we may conclude that you consume phenylalanine all the time. Oh man, this had me chuckling and is a great TLDR for many supplements.

If you have phenylketonuria, then you can't metabolize it very fast and so anything in excess of what your body needs becomes a liability.
