Exercising without a gym

[Nolicense]

isn't there a theory tat states u need to exercise more than 30 mins. Reason is tat 1st 30 min is to burn carbo n there aft fats will then start to get burn off.......

 

maybe? but if we eat low carb, and the ready store of energy in our muscles are used in the first 30 minutes of exercise, then we start burning fat, how do you explain that our basal caloric requirement at rest is for example 2000cal and exercise only burns like 300cal for example?

 

so burn fats after 30 minutes exercise or burn fats all day long?

yeah i can imagine the type of misinformation these people take as gospel.

the idiot is fat now and eats his "healthy" diet.. instead of learning from you when you were once fat.

he cannot see truth even when it is standing right in front of him.

 

f@@k him la bro. such pple deserve to die early from "healthy" diet.

I think there's no need for this. They were just brainwashed by the "experts" over the decades, right from 2 generations ago. Nobody deserves to die over bad information, from "experts" no less.

I've met a number of friends the last few weeks. All of them said, "what happended to you?" "Are you on diet?". To all, I reply "sort of". Many agreed I look better. Some go on to ask more, some politely just stop there. For those who're really interested I'd explained some more. To all, I answered, "I just cut my carbs which means no rice and noodles and anything that has sugar and flour..." and "...increase my fats intake". Those few who genuinely interested to find out more, I would explained more and promised to email some stuff for them to read.

 

Well, we can't force feed anybody anything. And if the proof is standing right in front of them and yet they can't see...

yes i think there IS a need for this. i get people CURSING me an early death. what do you think???

"you eat like that you will die soon"

"you will die from a heart attack even if you lose weight"

etc etc..

 

do you say such things to people you are concerned about? or is it FEAR talking?

people who are closed minded and brain washed are all just NOT thinking.. they just FEAR.

everybody sing the same song, and if you sing a different tune, they curse you. i say f@@k them.

[Nolicense]

same here bro, if they don't want to listen to me over the national PROPAGANDA, so be it.

do you notice these propaganda is always TELLING us what to do?

it is never EDUCATING what is the actual research.

 

well whatever.. i say let evolution take its course. don't need stupid people to out live us.

crap.. i don't drink..

they are not cursing u, they're just repeating what they've learnt from the food pyramid nonsense all the way back in pri sch. I see no need for u to use the F word or to curse them back in any way. U think that's gonna help anything?

 

Anyway, the tides may be changing. My wife noticed one thing:

 

For those of us who attended pri sch in early 80s, will have learnt in Health Education, to eat most of our diet in carbohydrates and eat least amount of fats.

 

Today, u don't really see the dreaded food pyramid anymore, just recommendations to eat fruits and vege (urgh!! are they really better than rice? I used to think so, now i don't) and "eat everything in moderation".

 

At least they don't push carbohydrates anymore!

 

Anyone else noticed that?

[Nolicense]

if you go to the polyclinic, the food pyramid is still pasted on the walls.

i think the food pyramid is not put to death yet and won't be for a long time

[Skunk]

At least it's not explicitly carb-friendly....but yeah, the dreaded pyramid is still there lol

 

They have something to do with the Egyptians isit? LOL

so much for the pyramid LOL

That's the danger of what people consider to be "normal"...

 

Just because everyone else is doing it - the "experts" are advocating it - it must be "correct"...it is often NOT

maybe? but if we eat low carb, and the ready store of energy in our muscles are used in the first 30 minutes of exercise, then we start burning fat, how do you explain that our basal caloric requirement at rest is for example 2000cal and exercise only burns like 300cal for example?

 

so burn fats after 30 minutes exercise or burn fats all day long?

I think it's the old school of thought where you do "aerobic" exercise at a constant level. The glycogen in your muscles supposedly takes 30 mins to be used up, then it switches over to fat burning.

 

In my experience, it is way too optimistic to think anyone can deplete their body's glycogen stores within 1/2 a hour by doing an aerobic activity like jogging.

 

Which is why I always do a highly intense workout (as hard as I can with as little rest that I can, until breathing is severely difficult) session of usually around 1/2 hour, then do some low level activity like an easy jog or even a walk for 1/2 an hour after.

 

In any case, you don't need to eat carbs to have stored glycogen in your muscles. Your body is perfectly capable of making it by itself through gluconeogenisis.

 

To prove it, you can do this experiment if you have a blood glucose meter:

 

1) don't eat a single thing for 24 hours

 

2) measure your blood glucose

 

3) exercise hard for 1/2 a hour

 

4) measure your blood glucose again

 

Most people will think that your blood glucose will crash and that you will faint. But actually, the opposite will happen. You blood glucose will RISE despite having fasted for the last 24 hours. The human body is an amazing thing.

 

There is simply no dietary need for carbohydrates.

 

 

Carbohydrates: No dietary requirement but metabolically critical

FRIDAY, AUGUST 28, 2009 AT 12:27PM

 

 

Reader Mallory has asked some questions, which I will use as a framework for talking about the metabolic need for carbohydrates.

 

In response to "what are the Triglyceride/fatty acid/Krebs cycle and the Randle cycle and can you comment on Taubes description of these in GCBC?"

 

For starters, the triglyceride/ fatty acid cycle (not really a metabolic cycle in the sense of metabolism of substrates, just a feedback mechanism really) as described by Taubes has nothing whatever to do with the Krebs cycle. That is just his term for the equilibrium between esterification and lipolysis and the transport of Triglycerides back to adipocytes from the liver.

 

The Kreb's cycle is totally different, occurring inside mitochondria and is the keystone of aerobic respiration. That is what you are using when you burn fat or glucose aerobically and amino acids and ketone bodies can feed into it as well. The Kreb's cycle is very efficient, and is employed as long as there are enough substrates and oxygen available in most circumstances. It is not determined by diet, really, it is like your furnace if you live in wisconsin in the winter. It is always on to some degree when it has substrates in a functioning cell with mitochondria.

 

The Randle cycle also is not really a cycle of metabolic substrates the way the TCA or Krebs cycle is. The Randle cycle is just mutual feedback between glucose and NEFA (non-esterified fatty acids) or ffa (free fatty acids, same thing) that determines which is the predominant energy substrate. When glucose in the blood is high, glucose is the preferred energy substrate and glycerol phosphate, a metabolite of glucose, rises in the cell. This is the backbone of triglyceride (fat) and fat storage is thereby stimulated and lipolysis inhibited. Glycolysis is stimulated so more glucose can be burned (Usually in the Kreb's cycle)

 

(Important: note that inhibited does not mean stopped! It means the balance is towards fat storage but there is always lioplysis and esterification happening at the same time! Think of patrons passing by a crowded bar. Some enter and some leave. The change over time in the number of patrons in the bar is determined by the net difference between those leaving and those entering over time. That's integral calculus, basically. The point is, you don't have to stop people from leaving to get a bigger crowd, just shift the balance so more come in than go. )

 

Conversely, when NEFAs are high, the balance between lipolysis and esterification is shifted so there is net release of NEFA for use a substrate (usually burned in the Kreb's cycle again) and glycolysis is inhibited (again, not stopped, but inhibited) Part of this mutual feedback is being mediated by insulin, which is responding to glucose levels, among other things.

 

So the Randle cycle is just the mechanism whereby your body "knows" how to shift fuel sources based on fuel availability. Makes sense, as multicellular life was founded first on metabolism of glucose. The ability to store and burn fat (much more efficient than glucose) evolved later. You need mitochondria to bun fat. Almost any living cell can burn glucose, with our without mitochondria. It makes perfect sense that we are evolved to be able to use either glucose or fat for fuel.

 

PaNu dogma is that we are healthier when spending more time in fat-burning mode. This dogma does not, however require us to fantasize that we are somehow unable to metabolize glucose or that glucose is useless as an internal fuel source. It is adaptative that humans can survive well for long periods, especially when calorie restricted, with carbohydrate as the predominant fuel source. It is entirely consistent that fatty acids are the best fuel when available for most processes, but that glucose remains a backup fuel both on a dietary and internal metabolic basis. How long would our ancestors have survived if they were unable to eat plants?

 

Let's stipulate that there is no absolute dietary need for carbohydrate. Is there a metabolic need?

 

Definitely.

 

As most of you know, fatty acids cannot cross the blood/brain barrier. Neurons can shift about half their metabolism to ketone bodies, but still require a gradient of glucose that can diffuse into the brain. If your blood glucose level drops too low, you are in a coma. Also, red blood cells require glucose.

 

Finally, apart from these special situations, there is another very significant situation in which it makes perfect sense that we have retained the ability to burn glucose generally.

 

That is called anaerobic glycolysis.

 

When you need to perform a lot of work very quickly, like running from a predator, or spending twenty minutes lifting weights, you are not burning fatty acids. Aerobic glycolysis and lipolysis are very efficient but too slow for very high intensity tasks.

 

Any time you need high intensity work done by muscles faster than can be accommodated by aerobic respiration, you are absolutely, positively, using glucose for anaerobic glycolysis.

 

I don't care if you have not eaten of the plant world in eons, that is what is happening.

 

The question was asked: "does low insulin keep muscles from burning glucose"

 

For as long as there is aerobic work, with low insulin levels, fatty acids will be preferred. However, the instant anaerobic work is done, you are absolutely using glucose to do it because you cannot burn NEFAs anaerobically. If I lift weights or sprint on a 15 hour fast, my insulin levels are very low, yet I can instantaneously burn glucose anaerobically.

 

How about: "When insulin is low the liver does not give up the glucose."

 

Generally False. It's just the opposite. When fasting or just between meals, you are constantly burning a small amount of glucose in your brain (hopefully) and you need to constantly maintain your serum BG level. If you did not replenish your serum BG from somewhere, it would drop to dangerous levels. In order to make up for the glucose consumed, and in response to falling glucose, hormones like glucagon and epinephrine are released, which promote gycolysis of liver glycogen, which is then released into the blood.

 

Good thing, too, or I would quickly be in a coma with my daily 15 hour fasts.

 

Finally, I need to make sure everyone understands what is happening with glycogen in the liver if you eat no carbohydrates (or less than replacement levels, like I often do on VLC) .

 

It is still there. Really. You have lots of glycogen stored in your liver as the glucose storage depot to keep your blood glucose stable. If you don't eat enough carbohydrate, this is where gluconeogenisis comes in. GNG is induced when your liver glycogen has been depleted to a certain critical level. As discussed in my previous post, amino acids will be used to make new glucose (hence, gluco- neo-genesis) and the glycogen will be restocked.

 

The big difference between VLC and high carb eaters is in the turnover of liver glycogen. Th high carb eater is using it as his main fuel, so his "gas tank" is being both filled and emptied simultaneously at a higher rate.

 

Everyone has glycogen in their liver, and everyone uses it.

 

The Final Question asked: "Is excess protein just peed out?"

 

No. Unless your kidneys are diseased, there are no protein or amino acids in your urine. Excess protein not used for new protein synthesis may be burned (efficiently or inefficiently) or stored as fat. If metabolised, urea shows up in the urine as a byproduct, but amino acids are not just spilling out like your body doesn't know what to do with them.

 

To repeat from my prior post, there is no particular fate for any macronutrient in your diet, and any excess substrate with caloric value can be stored as fat or burned. If you can eat excess protein or fat or for that matter carbohydrate and not gain weight, that is only proving that your diet has not deviated from favorable insulin levels, your caloric intake is low, or whatever. It is not because that macronutrient "can't be" turned into fat.

1) don't eat a single thing for 24 hours

 

Impossible to be done by people who live on a carb-heavy diet without feeling extreme discomfort, fatigue, giddiness and weakness.

 

But possible for us, on a high fat diet :)

 

The day before, i just went 14 hours without food. In the old days, I wouldn't have lasted 3 hours.

 

U want them to die ah LOL

I'm just glad the mainstream is even reporting about the distinction of LDL particle size nowadays. It's at least heartening to see that.

 

When people see the logic behind it, there is simply no choice but to totally shift their paradigms about what is healthy eating.

 

Congrats on your daughter's baptism!

Haha. Quite true.

 

I do 24 hour fasts quite regularly. At least twice a week. No problems at all man. In fact, it feels damn good!
