Body Energy

I know that the body creates energy from carbohydrates by turning it into glucose, which the muscles use to get power. ( correct me if im wrong or not thourough on any of this, please )

i know that people can increase protein to reduce carbohydrate intake, to reduce fat, and still produce energy for the body.

but my question is...

what if someone has no carbs to burn, or very little protein in them, what happens to the body, besides feel tired.

like when someone works out and has no carbs in them, what happens to their body.

Re: Body Energy

That's where the Atkin's-type methodology comes in. The body burns it's stored fat. The body can squeeze about 10% of the calories in triglyceride molecule (the glycerol part) and quickly convert it to glucose. The rest of the fat molecule can be burned by cardiac muscle (heart likes fat) and some is discarded as ketones and aldehydes. (short version)

Unfortunately, this process is ineffficient and the body will continue to consume protein which yields 40% glucose because (that's what the brain needs) and this protein comes from muscle tissue (and later from internal organs.) THis starvation process (low protein) is called kwashiorkor.

When there is no more bodyfat, the protein consumption goes full throttle and death comes pretty fast!

Re: Body Energy

basically if the body doesn't have anything to make energy off of then it starts using every last source possible, and if that is all used up, then it will use itself, like your muscles will break down and try to re-use that for energy.

Re: Body Energy

Actually, your body will use its own protein (i.e. muscles and organs) as a fuel source before using protein ingested through diet. Dietery protein isn't a very usable energy source- hence the "fat meltaway" on Atkins.

Re: Body Energy

right, but when a person eats and their body makes glucose, insulin travels the glucose to the muscles and organs. so the muscles use that energy first, but it is redistributed by eating.

Re: Body Energy

When someone is calorically deficient, whether the shortage is caused by eating very low carb, low fat, low protein or low everything, extreme fatigue is the body's way of defending itself.
The only way the body can survive is to keep caloric comsumption at a minimum and if that means one cannot move, then so be it.
Survival until tomorrow is the number one goal of evolution.

A good workout cannot be done on a starvation diet, the body just won't cooperate.

Re: Body Energy

it's such an effort to count all the calories and protein consumed in a day. i wonder if they make a program for it for the palm pilot. but then i'd have to carry that thing everywhere.

i hate going into a soccer game having a full stomach, cause i fear having to go to the bathroom. also i'm on adhd medication so food goes through me quickly.


but what should i be focusing my diet on? i know that i need between 50-100g of protein a day, and around 3000 calories on extremely active days. is this right? and should i be worrying about carbohydrates?
