I have a biochemistry exam tomorrow and this is some of the things I've been studying:
Dietary Carbohydrate Influence Nutrient Oxidation:
After you eat, most dietary carbohydrate is readily oxidized: either used immediately for
cellular functions or converted to glycogen for storage in the liver and the muscles. On
days when you eat a lot of carbohydrate, more carbohydrates are oxidized. A metabolic
process called diet-induced thermogenesis, may increase.
The elevation in your blood glucose and the increase in your glycogen stores put the brakes on appetite (in most people) so you do not eat more than you can use.
As a result, glycogen storage in the average person rarely reaches maximum capacity, which is about 1,500 carbohydrate calories.
Balance between carbohydrate intake and storage could also occur if excess carbohydrate
were stored as fat. It is theoretically possible for this to occur. However, having enough
excess carbohydrate to convert to fat would require an extremely high carbohydrate
intake for several days. Some experts have estimated that an intake of 2,000–2,500 kcal of carbohydrate over several days, after carbohydrate stores were at maximum, would be required before carbohydrate would be converted to fat.
Dietary Fat Influences:
If you decreased your carbohydrate intake? Would this force more fat to be burned?
Many popular high-fat, low-carbohydrate diets would lead you to believe so. Unfortunately,
replacing dietary carbohydrate with fat promotes obesity for several reasons:
1. Although the fat in your diet creates a feeling of stomach fullness, fats are overall less satiating than carbohydrates.
2.Carbohydrates control the rate of fat oxidation (“fats burn in a carbohydrate flame”),
and when carbohydrate stores run low, fat oxidation slows.
3.Fat intake does not stimulate an equal and proportional increase in fat oxidation.
When fat oxidation is less than fat intake, fat storage results
4. Unlike glycogen, fat stores are not limited in size.
- Nothing new but here is a good explanation I took from a book and wanted to share with you.
Thats what I was thinking too because if we were meant to eat fruit then being allergic to fructose does not make much sense, it would have to be a mutation.
Anyway thanks for the reply man
there is no "meant to" about evolution. humans have evolved to eat what ever is available. evolution is based on mutations - most mutations are bad or have no effect.
A fructose enzyme deficiency is obviously not beneficial but it is a known condition.
Mutations can be good or bad depending on the situation, depending on the selective pressures.
Mutation adds advantage to an organism, making it better able to survive and reproduce in a particular environment. This way individuals eventually become the dominant type in a population and evolution gradually takes place.
Thanx, that was really nice informartion. But still some people are gaining weight/fat on this lifestyle so something must be wrong?
Did it say how long it took to replenish glycogen stores?
Yes, but that must be bacause of other underlying problems in their metabolisms.
No, it didn't said how long it took to replenish.
ya i've put on wieght as well, although i have been drinking smoothies and having honey sandwiches - cut out the egg yesterday, and am buying b12 as I think that's what my body is looking for... as would seem to be the case because i bought a bottle of b complex and I am fine...
but fat gain! yikes, maybe I need to burn some calories! hehe
And the honey sandwiches. :p
yup :D hehe
Good job nixing the eggs, Nick.
it's one thing to hear it's not ideal, and another to have some solid reasons as to why--
In case you haven't see the full buzz yet, you might appreciate this:
thanks will look at it now... But I wanted to say that I am transitioning to raw, from being a meateater, an honey is my last... I am officially 811 raw when I eat the bananas and dates, and spinach that i got from an organic farm store, orderd and delivered thursday, but still have to wait until they ripen
can oranges, pears and kiwis riped after they've been picked?
am going to look at that website now..
For sure, you're making excellent strides, Nick.
Keep up the good effort, and let me know if I can be of further assist.
This is an answer to your ripening question, oranges taste yummy months off the tree, pears only ripen of the tree, Kiwifruit are avalible ten months of the year yet are only picked off the tree for two months. They keep them in cold storage and bring them out of that environment and then they ripen up.
