Time for a little controversy: CARBS KILL YOU

[ViperRKO]

---

true, our body can derive energy from proteins and fatty acids. BUT, carbohydrates man ang pinaka-efficient.. lahi man ang pathway pag breakdown sa 3 different macromolecules, but they converge at some point. like for example, fatty acids can be broken down into pyruvic acid which is a substrate sa krebs cycle = makaproduce gihapon ug ATP ang body. similarly, certain amino acids can be converted into different substrates gihapon sa krebs cycle..

now, why do i say mas efficient ang carbs? when you break down carbs, you need less oxygen than you would when you break down proteins or fats. (research about respiratory quotient for this). also, when you break down too much proteins, mutaas imong ammonia levels (byproduct of protein metabolism), which is toxic (may cause encephalopathy).. on the other hand, when you break down too much fats, mutaas imong ketone bodies (byproduct of fatty acid emtabolism), which can lead to ketoacidosis..



you have to be specific about the type of carbohydrates that can cause your insulin levels to shoot up.. simple carbs are the culprit here.. kay sayon ra man sila i-digest so dali ra sad mutaas ang blood glucose = your pancreas increases its insulin production.. pero kung complex carbs, dugay man ma-break down so they don't cause fluctuations sa insulin levels nimo..

really? no evidence of high cholesterol being bad? in my first year of medicine, i've learned that high LDL levels can predispose you to cardiovascular diseases..

I'll try my best 2 answer this as best I can...I just hate reading stuff on d computer and u have a really long argument here, so if I go off to something irrelevant then feel free to clarify.

Ok...about the protein and fats thing you're right too much does cause harm. But the thing is if someone doesn't eat any carbs its really hard to get too much protein or fat into your diet. You talked about the relationship between carbs & insulin, well you should know that insulin is also what causes us to get hungry, right? When we're hungry our blood sugar's low and we look for carbs coz they raise blood sugar the fastest and it usually leads to a spike in blood sugar which has to be lowered by insulin and therefore makes it drop and we feel hungry again so this cycle increases our appetite to be much higher than its supposed to be, allowing us to consume a lot of calories. The thing is, you dont get that with protein and fat, in fact fat makes you full faster and longer, so without the presence of carbs were not likely to get enough protien or fat into ourselves to hurt ourselves.

Ok, now for the cholesterol thing...I already stated in another post that consuming saturated fat actually lowers its own levels in the bloodstream. And to add to that, a breakdown of lets say, animal fat, actually shows that 97% contributes to the production of HDL, the good stuff.

If u wanna see the breakdown let me know.

Ur absolutely right. Fats cant kill you. We all know saturated fats are the evil fats right?...well some might also know that having too much of that in ur blood stream is whats bad for you. The liver is what converts food into saturated fat, I dont wanna get too technical coz I dont have my kodigo's with me. ...but its true, saturated fat is a bad thing and it does cause heart problems but here's the twist...its actually carbs that cause an increased production of saturated fat to go into your bloodstream while actually CONSUMING saturated fat lowered the presence of itself in the bloodstream.

you can't absorb fats per se.. it has to be broken down for it to be absorbed and transported across the intestinal wall.. so it's incorrect to say "saturated fats in the bloodstream". source please for the text in bold..

I disagree with this whole premise.. one function of insulin is to allow the body to store your ingested carbs as glycogen in the liver for later use.. in a sense, it does lower our blood sugar levels, but not low enough to cause you to go hungry.. have you noticed that it takes hours for us to go hungry after eating? did you know that ang normal values for FASTING blood glucose is still within the normal range? it's because naa kay reserve of glycogen in your liver to sustain you for a longer period of time..

murag wala ko kasabot ani.. you can eat proteins and fats independent of carbs..

source please, kay as far as i know, animal fats, which are saturated, mao makacause LDL to rise..

But the thing is...I dunno what u learn in med school but I think u know how people get fat...because when they get too much glycogen in the liver and the muscles they go to fat tissue. Now how can that be possible if people didn't want to eat anymore. I mean I dunno man...I've talked to a lot of people, even a few doctors and they all agree when ur insulin rises and ur sugar drops, you'll wanna eat.

Yeah you can but u cant eat too much when ur on a low or no carb diet, based on my claims about carbs and on experience.

yes, you'll want to eat when your sugar drops, but the levels of insulin released after a meal won't normally cause hypoglycemia, unless there's too much of it.. what's more, the body is programmed to sense when sugar levels are getting too low so it can stop insulin production..

what i was trying to explain was, it isn't as simple as eat->blood glucose rises->insulin->blood glucose drops->hungry->eat again.. as i explained before, insulin sort of causes glucose to be used up SLOWLY instead of abruptly.. so it's more like eat->glucose rises->insulin->glycogen synthesis->glucagon->glycogenolysis(which happens over a period of time to stabilize your glucose levels)->glycogen reserves depleted->blood glucose drops->hungry->eat again.. plus, if you eat complex carbs as opposed to simple carbs, all this happens much more slowly pa gyud..

Yeah you can but u cant eat too much when ur on a low or no carb diet, based on my claims about carbs and on experience.

huh? even on a low-carb diet, you can eat lots of proteins and fats.. as the name implies, only carbs are restricted.. but of course, if you're trying to lose weight, replacing the carbs you've omitted from your diet with proteins and fats will certainly defeat your purpose..

[jangska]

all things can probably kill you if pa sobraan nmo.. kung di sad ka mo kaon patay sad ka. either way mamatay raman gihapon so enjoy life eat all you want basta di pasobraan.. life short y waste it..

your point of view might come from someone who consistently consumes sugar and carbo, how about trying no carbs and sugar for a month?

as for me, when I went most meat(some vegetables), no carbs, no sugar....I can survive eating just twice a day.

pag holy week, nibalik ko ug rice just for fun, I get to experience "dizzying" hunger, so nibalik ko ug most meat and tolerable ra kaayo ako hunger.


although, Im tweaking the diet right now kay lahi ako results sa mga PaNu practicioners.

I still like it!

There has been no evidence that really proves ANY cholesterol causes any cardiovascular disease or any disorder for that matter. But the latest findings is that increase in insulin levels (caused by carbs) causes more than just diabetes or being hyperactive it also causes people to binge more coz it raises their appetite after the insulin drops after the rush. But here's the best part...increased levels of insulin have been found to BE THE CAUSES OF CARDIOVASCULAR DISEASE.

So here we go...u didn't shoot me down just yet.

I'm sorry, but if you eat complex carbs + fat(slows Gastric emptying). Then there is no way in hell you'll get an insulin spike. No increase in insulin = no cardiovascular disease

i can't do that since i'm breastfeeding and i can't jeopardize my milk supply just for some experiment.. and even if i wasn't breastfeeding, i wouldn't want to coz i believe we need carbs.. the right types of carbs and in the right amounts.. plus, i like to eat several times a day to keep my metabolism high and to help with elimination (fiber is a form of carbohydrate baya.. by the way, i'm curious, with that kind of diet, don't you get constipated? where do you get your roughage?)

not all carbs are evil you know.. just choose the right ones..
