| | I dont have time for any detailed explaining on my behalf.
But i want to say, importantly, that the end product of gluconeogenisis is not glycogen - its is glucose. If you cant get these terms right then i find it hard to believe that everything your saying is correct or worth worrying about.
Its no easy subject. Picking and choosing information to read wont help you understand the whole grand scheme of things let alone personal conceptions and ideas based on what you do know or think you know.
By the way theres always ATP, without it your cell gradient will fail leading to cell death or necrosis. |

| | | Glycogen is a polysaccharide of glucose though. It's not my personal beliefs... the idea of protien as an inefficient source of energy and can't be turned into fat... High protein diets have been popular since the early 1960’s it's not my personal idea... ><
just google ketogenic or lean protien diet o_O

| | | The end product of gluconeogensis is glucose fullstop
Then it can be used for glycolysis or other other pathways. Why would it turn to glycogen? that defeats the whole purpose of gluconeogenisis which is to provide the body with glucose that isnt readily available as glycogen.
Glycogen is a highly branched polymer. Which requires specific enzymes to create it and degrade it back to glucose molecules. |

Glycogen is the atp sources from the liver and muscles right? is it just excess amounts of glucose that turn to fat or is it excess amounts of glycogen?
since your right I don't know the terms very well let me get a better understanding
protien can be used for energy? What source of energy is it converted into if not glycogen which >< that wouldn't make sense your right protien turning into glycogen doesn't make sense but I do know it turns into glucose but what form of glucose?
from glucose what turns into fat? I always thought any excess glucose turns into fat if not used?
Then what's the reasoning behind lean protien diets and ketogenic diets if they don't work? why do people go on them? I know ketogenic diets are easy for one but lean protien diets ussually aren't. I always thought ketogenic diet was manipilation of the hormones to induce ketosis and lean protien was to lower insulin... if those don't work what's the reasoning behind these diets? Competitors do use these >_< so I don't get why they would if they don't work?

| | | If someone could say like no, basically protien can be converted into fat just as easily as carbs because, then state the proccess of how protien is turned into energy and then fat and how protien is suffiecient at supplying energy for the body... then i'd be really happy >_<

| | | protein isnt efficient for supplying the body with energy.
Protein isnt specifically designed for our energy needs as they already have many important functions such as enzymes and cytoskelotons, not to mention the inability to be stored (so thats why excess is either used as energy, excreted, or turned into fat.
The energy is stored in the substrates bonds. It isnt necessarily a linear realm where protein turns to energy, the energy then to fat. The energy isnt simply released and then turned into fat. It bypasses direct ATP production, is converted to fat which can then be used for energy or simply just stored.
Hope i got that right i might be rushing things but hopefully that answers something. |

So, you could easily argue both sides.
I'm simply saying that the issue of restricting / avoiding carbs as it pertains to insulin sensitivity / fat storage is a pretty much a non-issue for most healthy people.
As far as looking to what male models and bodybuilders do for guidance - they certainly wouldn't be my first choice of who I'd turn to for nutrition advice ...but that's just me. Quote:

As far as 'single digit ' bodyfat goes ,many many years ago I was able to hover around 8% bf - and all while scarfing down boatloads of carbs ( i.e.well over 50% ). There's more than one way to skin a cat I guess.
Again, I don't turn to bodybuilders for guidance - most of them are " juiced " IMO ( which, sadly, speaks for itself IMO ) - and most people on this forum aren't trying to get to 4% +/- like bodybuilders are when they cut. Quote:

Again, 20% is rarely a number I see in articles etc. ....most often it's 25% or 30% and, to lesser extent , 35%...numbers cited from " people with degrees in exercise science and nutrition and a couple models "
As for models ? No comment. Quote:

btw - what does the The National Academy of Sports Medicine recommend as far as protein and carb intake for pound that you weigh ? Quote:

But under what conditions is there a high probability that excess protein WILL get stored as fat ?

| | protein can be thrown into krebs cycle, the result of krebs cycle is eventually ATP, which is energy. It's a process that requires some energy, but you still get more ATP from it than you use. That's pretty much all I know about that. I don't know if ATP can be converted to fat? When is carbs turned into fat anyways? .. and how does it happen? what's the name of the process? (so I can google and get some images  ) |

| | | Protein is a relatively expensive (and inefficient) energy source when compared to carbohydrates, IMO.
As much as some (myself included, on some forms of sugars) frown on sugars and (some) starches, these carbohydrates are your body's MOST important fuel source.
Your body breaks them down into the simple sugar glucose. Glucose is either directly consumed by your cells for energy, or it's stored as glycogen in the muscle or liver for later use when your energy demand requires it. These are trather--- simple, ---accurate facts.
From what I read on this subject matter:
When glucose is in short supply, your body will begin to utilize fat and protein (even muscle protein) for energy to preserve glucose levels. This can be rather complex.
If you do not obtain enough glucose from the food you eat, your body has the ability to convert protein or fat into glucose. As you burn calories (energy) through exercise, or remain in a carbohydrate-fasted state (as on low carb diets), your body scrambles to make glucose in an effort to maintain its glucose.
From what I have read on the subject (thus far) its glucose (and its conversions) that determines how fast your body burns fat, how well it performs physically, and how fast you recover after training. Yes, low carbohydrate diets can be an effective way to manipulate your body's glucose, IMO, in the short duration. Since the body is in a carb-depleted state, it is forced to convert nutrients (etc) into glucose to meet its energy demands. But, I do not think one ought to do it---for extended periods of time.
Best wishes,

| | | ATP isnt converted to fat or anything, its been made so its used for the cell.
If in excess, the glucose which gets down to be Acetyl CoA can then be turned to fat via the reverse of beta oxidation. So its just the same but in reverse of fat oxidation.
And i wouldnt say the protein is chucked in its the amino acids. Which depending on which ones will determine what they turn in to and therefore there position in metabolism. |

| | well to be honest optimal health isn't my goal I know there are health risks for keto and lean protien diets, i'm only trying to lose those last maybe 5-10 lbs to get into single % I'm doing 5 days of hiit and 4 days of lifting and it's going down so slowly from calorie count alone i would think i'd be going down quite a bit faster and i'm not losing any strength it seems so I don't think i'm losing muscle mass. =/ And yeah this diet is a cutting diet I have no plans on staying on this for extended periods of time.

| | | any luck? I'm with you, on trying to find menu ideas of what to eat when. I am also new at this and trying to have it simplified. I work 4 days a week, married, 2 kids, drive them around a lot.
