Use that reduced appetite in those last pounds. I suspect that in the last 10 not even the appetite reduction still works and that a fair number will need to be hungry during that time. I also notice that I disagree with the goal weights of a LOT of people. Pick a goal weight below what your body considers its ideal and the only way to get there is hunger during the losing phase followed to endless hunger during maintenance as well. - quote - > > Low carb tends to increase glucagon levels and glucagon draws

I'd been cutting fat out more to save on total calories... > Guess that is a mistake? Probably why I keep getting stuck. While out of ketosis (actually ketonuria) cutting carbs to get into ketosis works best. But once in ketosis further cutting carbs does little but risk T3 drop and a stall. Consider CCLL the bottom for carbs at least half the time. Since the higher carb foods early in the carb ladder tend to be more filling veggies, Atkins tends to be isocaloric after Induction - The increased carb quota is roughly offset by spontaneously eating smaller portions of fat and/or protein. It's easy to think you're trading more carbs for less fat at this point ... Once in ketosis cutting protein not fat seems the next step. Dietary fat does a better job of increasing glucagon release, though do some research and you'll find claims that protein is better at it so there doesn't seem to be a good scientific consensus on this point. Or for the same total calories swap extra fat for less protein to improve the ratio to increase glucagon. Switching from 500 calories of pepperoni to 500 calories of lean turkey is not the way to go. Switching from 1000 calories of pepperoni to 700 calories of lean turkey, much harder to say. Note that protein is essential so there's a point below which reducing causes problems, but that level tends to be much lower than what most westerners eat. Then only cut fat to cut total calories. Deal is, when trying to bust a stall when low carbing cutting calories becomes the fourth thing to do - 1) Check for calorie creep and renewed overeating. Aka correcting calorie overage not cutting calories. 2) Recalibrate ketosis and CCLL by getting out of ketosis then back in to avoid T3 drops. 3) Work the fat to protein ratio by cutting protein and increasing fat at the same total calories to increase glucagon. 4) The big hammer approach of lowering calories. - quote - > Oddly enough, I lose weight FASTER on a fat fast than on a total fast.
While that is surprising before reading the original fat faststudy, it isn't surprising after reading it. It's the glucagon drawing fat from storage that matters the most. Lower both dietary fat and protein and you lower glucagon release. That's a defense mechanism to lower metabolism during a famine. |

| I deleted most of the coversation to avoid too much info to read; however, I have had some experiences with total fasting. I agree with most authors that it is not really a good way to lose weight, although you could lose some depending on how long you go. Fasting by definition is total lack of food; so people who term something a "juice fast" or a "Fat fast" are just begging the question and are using wrong terminology. Those things are "DIETS". A "Fast" only includes water. I think the real value of fasting is the self-control which is manifested by doing it.

What the store does is take pork that fixin' to outdate, re-package it and knock the price down and sell it as "trimming". Some of it is shoulder or butt, but some of it is also fairly lean rib and loin chops! I kid you not.: http://i12.tinypic.com/4p3tqug.jpg One cannot live on chicken alone... ;-) I've found when I take this stuff to work (cooked of course), 8 to 10 oz. of it stuffs me for a good 6 hours. My weight is finally starting to drop again. Slowly, but still encouraging. One of the real issues with low carb dieting is the damned price of meat. - quote - >

"Wolfers" consume a lot more calories than taking time to enjoy a meal as it takes a bit of time to become satiated. I watched my BIL eat a couple of chili dogs from Der Weinershnitzel one day when he came over to use my laser printer. My god. He snarfed each one down in two bites and maybe 3 seconds. I don't think he hardly stopped to chew. No wonder he weighs over 300 lbs... <sigh> He's a big guy and can probably stand to weigh about 220 at most, but he's really starting to have health problems and he knows it. It'd help if my sister was not a "fat acceptance" buff. ;-P I worry about them. - quote - >

"metabolic advantage" stressed by Dr Atkins. (He failed to mention it is roughly proportional with amount to lose and hits zero once there's 10-20 pounds left to lose). Low carbing keep the metabolism up somewhat compared to low fatting and low calorie. Five percent difference in the first 6 months, none after that comparing low carb to low fat but those studies include calorie restrictions for low fatters so it might be a little more than 5%. Low carb tends to increase glucagon levels and glucagon draws fat out of storage. Whether those excess calories are burned through higher rest metabolism or wasted through ketone evaporation doesn't matter all that much - More fat pulled from storage is what almost everyone diets for in the first place. - quote - > Rather, the amount you eat is decided by your body's nutrient-sensing

More specifically *both*. The high fat percentage of low carbing> > > I presume you mean dietary fat. > > Either. triggers higher glucagon levels which draws stored fat out. There's a calorie range where eating more fat causes more stored fat to be withdrawn, and that calorie range is close to the common guideline of (current weight in pounds * 10 calories). Even better, while fat has roughly the same filling effect as protein calorie for calorie, fat tends to keep hunger from coming back longer than protein calorie for calorie. Eating more fat doesn't end up equaling eating more calories - It ends up meaning eating less protein. Very much the opposite of obvious in several ways. - quote - > > > So whether you're burning your own muscles depends on how much

I know that the body's glycogen stores work that way, but folks on a fast seem to do better than I think they should. If the body really did start consuming its own muscle, I think starvation would lead to muscular weakness more than it does. So while I have no idea what sort of stored protein a body has, I think it's got to be more than that couple of days in the claims. Note how weak my logic in this belief is and how lacking my supporting data is. - quote - > > > High fat diets are more lean sparing than high protein diets per

What it comes down to is that one molecule of fat is made of one molecule of glycerol bonded to three molecules of fatty acid. The glycerol has three carbon atoms, and the fatty acids 16-20ish each, so the fatty acids make up ~95% of the fat molecule; when talking about fat, we tend to forget about the glycerol and just treat it as a bunch of fatty acids. Anyway, fatty acids can't be made into glucose, only burned or made into ketone bodies, but glycerol can. However, it's a rather small amount - you need two glycerols to make a glucose, so you get half a glycerol per molecule of fat, which also gives you three molecules of fatty acid, worth 8-10 turns of the Krebs cycle each. - quote - > > Glucogenesis from protein is 50ish% efficient by calorie.

It's still less efficient than fat, but better than 50%, i think. I think this metabolic efficiency stuff is a red herring. It's not like you, or your body, eats a specific number of calories of whatever food and then stops, and protein's better for you because less of those calories become available; you eat as much as it takes to stop you being hungry, so if protein was less good at stopping you being hungry, you'd eat more of it, and end up with more calories in your blood.

I've found I can maintain better ketosis if I go ahead and have some carbs every couple of weeks. That very thing is designed into Lyle's PSMF diet. I've done fat fasting and can lose about 1/2 lb. per day doing it. Atkins recommended that you not do it for more than 5 days (iirc, I've not read his books in awhile) as it's nutritionally deficient. I did it for 2 weeks one time and lost 10 lbs before going for some protein and veggies. It's hard as hell to stay on that thing tho' as you are always hungry. 1,000 calories of fat is not a lot of food. Part of that weight loss tho' is muscle glycogen depletion which is why when you DO indulge in carbs after strict low carbing, you will see a sudden weight gain (usually about 5 lbs. in my case) due to water being pulled into muscles along with the glycogen storage. This is why carb depletion is done prior to a contest then you "carb up" the day before the actual competition. The increase in fluid retention inside of the muscle body is often overdone giving you some increased muscle hardness for the stage. -- Peace, Om Remove _ to validate e-mails.
