| Re: Some Newbie questions being hungry during the first couple of weeks on any radical dietary change is going to leave you feeling hungry. does your diet still consists of a lot of carbos? if you can substiture other things (like MikeB suggested) then that will curb your hunger.... or... you can empower yourself to expect to be hungry and learn to deal with it by doing other things... such as a hobby that occupies your time.
i've found that after several weeks, the hunger does diminish... tho it really never goes away if you're reducing calories to a much higher degree than MikeB's 2000 a day.
here's some information i dug up on the internet that explains why carbos make you hungry.... as well as the basics of food metabolism. surprisingly, eating animal fats is not what makes your body store fat. the culprit is carbos, sugars, and insulin.
"The ratio of macronutrients protein, carbohydrate, and fat-in the meals you eat is the key to permanent weight loss and optimal health. Unless you understand the rules that control the powerful biochemical responses generated by food, you will never achieve optimal wellness.
Unfortunately, many people don't really know what a carbohydrate is. Most people will say carbohydrates are sweets and pasta. Ask them what a vegetable or fruit is, and they'll probably reply that it's a vegetable or fruit-as if that were a food type all its own, a food type that they can eat in unlimited amounts without gaining weight.
Well, this may come as a surprise, but all of the above-sweets and pasta, vegetables and fruits-are carbohydrates. Carbohydrates are merely different forms of simple sugars linked together in polymers-something like edible plastic.
Of course, we all need a certain amount of carbohydrates in our diet. The body requires a continual intake of carbohydrates to feed the brain, which uses glucose (a form of sugar) as its primary energy source.
In fact, the brain is a virtual glucose hog, gobbling more than two thirds of the circulating carbohydrates in the bloodstream while you are at rest. To feed this glucose hog, the body continually takes carbohydrates and converts them to glucose.
It's actually a bit more complicated than that. Any carbohydrates not immediately used by the body will be stored in the form of glycogen (a long string of glucose molecules linked together).
The body has two storage sites for glycogen: the liver and the muscles. The glycogen stored in the muscles is inaccessible to the brain. Only the glycogen stored in the liver can be broken down and sent back to the bloodstream so as to maintain adequate blood sugar levels for proper brain function.
The liver's capacity to store carbohydrates in the form of glycogen is very limited and can be easily depleted within ten to twelve hours. So the liver's glycogen reserves must be maintained on a continual basis. That's why we eat carbohydrates.
The question no one has bothered to ask until now is this: what happens when you eat too much carbohydrate? Here's the answer: whether it's being stored in the liver or the muscles, the total storage capacity of the body for carbohydrate is really quite limited.
If you're an average person, you can store about three hundred to four hundred grams of carbohydrate in your muscles, but you can't get at that carbohydrate. In the liver, where carbohydrates are accessible for glucose conversion, you can store only about sixty to ninety grams.
This is equivalent to about two cups of cooked pasta or three typical candy bars, and it represents your total reserve capacity to keep the brain working properly.
Once the glycogen levels are filled in both the liver and the muscles, excess carbohydrates have just one fate: to be converted into fat and stored in the adipose, that is, fatty, tissue.
In a nutshell, even though carbohydrates themselves are fat-free, excess carbohydrates ends up as excess fat. That's not the worst of it. Any meal or snack high in carbohydrates will generate a rapid rise in blood glucose. To adjust for this rapid rise, the pancreas secretes the hormone insulin into the bloodstream. Insulin then lowers the levels of blood glucose.
The problem is that insulin is essentially a storage hormone, evolved to put aside excess carbohydrate calories in the form of fat in case of future famine. So the insulin that's stimulated by excess carbohydrates aggressively promotes the accumulation of body fat.
In other words, when we eat too much carbohydrate, we're essentially sending a hormonal message, via insulin, to the body (actually, to the adipose cells). The message: "Store fat."
Hold on; it gets even worse. Not only do increased insulin levels tell the body to store carbohydrates as fat, they also tell it not to release any stored fat. This makes it impossible for you to use your own stored body fat for energy.
So the excess carbohydrates in your diet not only make you fat, they make sure you stay fat. It's a double whammy, and it can be lethal.
Insulin is released by the pancreas after you eat carbohydrates. This causes a rise in blood sugar. Insulin assures your cells receive some blood sugar necessary for life, and increases glycogen storage.
However, it also drives your body to use more carbohydrate, and less fat, as fuel. And, insulin converts almost half of your dietary carbohydrate to fat for storage. If you want to use more fats for energy, the insulin response must be moderated.
Diets high in refined sugars release more insulin thereby allowing less stored fat to be burned. High insulin levels also suppress two important hormones: glucagon and growth hormone. Glucagon promotes the burning of fat and sugar. Growth hormone is used for muscle development and building new muscle mass.
Insulin also causes hunger. As blood sugar increases following a carbohydrate meal, insulin rises with the eventual result of lower blood sugar. This results in hunger, often only a couple of hours (or less) after the meal.
Cravings, usually for sweets, are frequently part of this cycle, leading you to resort to snacking, often on more carbohydrates. Not eating makes you feel ravenous shaky, moody and ready to "crash." If the problem is chronic, you never get rid of that extra stored fat, and your energy is adversely affected.
Does this sound like you? The best suggestion for anyone wanting to utilize more fats is to moderate the insulin response by limiting (ideally, eliminating) the intake of refined sugars, and keeping all other carbohydrate intake to about 40% of the diet. Generally, non-carbohydrate foods-proteins and fats-don't produce much insulin.
Insulin responses can vary greatly from person to person. But generally, more refined foods evoke a stronger and/or more rapid insulin reaction. One reason for this is refined carbohydrates lack the natural fiber which helps minimize the carbohydrate/insulin response.
Consumption of natural fiber with carbohydrates can reduce the extreme blood sugar reactions described above. Low-fat diets cause quicker digestion and absorption of carbohydrates in the form of sugar. By adding some fats to the diet, digestion and absorption is slower, and the insulin reaction is moderated.
Recommendations for them include long-term restriction of carbohydrates and an increase in dietary fats. For some of these people, it means lowering carbohydrate intake to below 40%, sometimes even as low as 20%. By moderating carbohydrate intake you can increase your fat burning as an optimal and efficient source of almost unlimited energy."
