ravenwolf, great job at summarizing... I had NO idea how to start that. I think I'm on nutrition overload right now as far as how it all works with the body.

Further to Raven's comment - you have to make sure you get enough protein, because if you don't and you start loosing weight, the loss may come from muscle tissue rather than fat. So that is why many weight enthusiasts take a whey protein supplement.

you are right ravenwolf. i didnt get this way quick,it took a couple of years of inactivity. when i say quick, i didnt really mean right now, i want to lose the weight sooner rather than later but i want to do it right. and that is where i get a little confused, i dont know the correct way to lose weight and to tone up it has never been explained to me. thanks for the help guys, i really appreciate it.

Loaded question.
Okay, carbs are the bodies preferred energy source. These are metabolized almost exclusively for energy and rarely, to my knowledge, used for anything else. Protein is used to construct body tissue and some hormones. Your muscle and organ tissue is composed of proteins - as is your hair and you nails. Protein is also used to build hormones like growth hormone and insulin. Fat is another energy source, though not as efficient as carbohydrate. Dietary fat (the kind you eat) is also used to produce various things in your body, though, I honestly don't know enough to tell you exactly what. I do know that higher intakes of dietary fat increase testosterone production in the body (a good thing).

Carbohydrates are our body's first and primary source of fuel. Just as coal is a trains primary source of fuel. It yields 4 Kcal of energy per gram. That means every gram of carb you eat is worth 4 calories. Like coal, carbohydrates are used only for fuel. The carbohydrates (energy) that are left over must be stored away for later use. The body stores the carbs into little storage areas in the muscle and liver in the form of glycogen. When these stores are full (which is almost always) the body compacts the carbs (energy) and stores it in the big EXPANDABLE storage units- FAT!
Fat holds compacted energy molecules. Therefore, fat yields 9Kcal of energy per gram. That is double what a carb yields per gram. So fat has 9 calories per gram. It is our bodies reserve fuel and for good reason- it's supercharged at 10 calories a gram! Fat that we eat can be used for energy or structure material. The brain eyes and the tissue surrounding the intestines are primarily composed of good fats. So the right kind of fat is definitely needed and very important to your body's growth, maintenance and repair. Bad fat is compacted stored fuel sitting on an animal's body to be used when its primary fuel (carbs) is unavailable.
Protein is also needed for the body for growth maintenance and repair. The entire body is made of protein. Hair, skin, nails, hormones and tissue are made of protein. Protein yields 4Kcal per gram just like carbohydrates (coal). Protein is much different then coal as a source of fuel. Protein is more like wood, a more versatile source of fuel. If you were to use wood to fuel the train you didn't burn it all up you don’t necessarily need to store it like carbs. You could take all the leftover protein (wood) and use it to build something of structure for your body. Wood is a great fuel source but can also be used to build things. Coal is either burned right then or stored away.
Ok so now we know that body fat on animals is stored, compacted energy at 10 calories per gram. Carbs are our primary source of fuel at only 4 calories per gram. Protein we need to build every aspect of our body and if worst comes to worst protein can be burned as fuel at 4 calories per gram. So when you eliminate carbs from your diet your body turns to its secondary source of fuel- stored FAT! There is no reason for you to use your reserve tank unless the main tank is empty! Well you might think, if I don’t eat carbs then I would be tired because carbs give you energy. Well, fat yields twice the energy of carbs per gram so once you start burning fat as fuel, not only will you loose weight, you will have twice the energy too! Protein must be consumed so that your body will keep being able to grow, maintain, and repair. Protein is your body's third choice of fuel. So as long as your body has fat to be burned and your eating protein you will be using fat as a source of fuel and the size of your storage tank will be reduced!

ok that makes so much sense. does that mean low carb intake would result in quicker weight lose? if so, is it healthy? mrmagical....i do hope i didnt take too much of your time but it helped in a huge way.
thanks

ok Carbs are NOT the body first energy source. glucose is. And we get glucose from all food sources. Carbs breakdown into glucose faster than the other types but non the less... and if you lose weight you will always be losing some muscle no matter what...it's just a question of in what ratio you lose it.

ok...here's a question to do with proteins...WHERE can we find them?

Meats, nuts, some fruits, and I now drink a whey protein drink to supplement with my weight lifting...
Proteins are made up of amino acids. Some of these amino acids are indispensable. Proteins can be classified has complete and incomplete based on their amino acid content. If a protein of a food supplies a sufficient amount of the nine essential amino acids it is called complete. If a protein contains low value of one or more of the essential amino acids it is considered incomplete.
Essential amino acids are: tryptophan, valine, leucine, isoleucine, methionine, phenylalaline, threonine and lysine;
Semi essential amino acids: taurine, histidine;
Complete aminoacids maintain life and provide fat normal growth of young and reproduction in the adult when fed as the sole protein food.
Incomplete aminoacids maintain life but do not support normal growth.
The best foods to eat for protein are not necessarily those that are highest in protein. The nutritional content of a food should be taken into account. Animal food can contain a higher percentage of protein than vegetable food but it also has a high percentage of fat. The calories that come from vegetable food come from protein, so it is actually a better source of protein. The rest of the calories come from desirable complex carbohydrates;
Most nuts and seeds provide more than 10 percent protein;
Most nuts contain complete and high-grade proteins. They rank and even surpass, flesh foods in the quantity of their proteins. Nut proteins are also free from pathogenic bacterial or parasitical contamination.
The following nuts are excellent sources of proteins (for more information see Fruit ONLY! Cure for one thousand illnesses)
Peanuts (raw) – Peanuts have 26% of protein;
Almonds - their proteins have a high biological value and some nutritionists say they are an excellent substitute for meat; Almonds have 19 %of protein;
Walnuts – contain 18,5 % of protein;
Brazil nut – this nut is very valuable and recognised has complete; Brazil Nuts have 17% of protein;
Coconut - is an excellent and complete food; Coconut has 6% of protein;
Cashew and chestnuts – have 3% of protein;
The following fruits are also rich in proteins:
Dates – 2,5 % of protein;
Avocado – 2.5% of protein;
Grapes – 1,5% of protein;
Figs - 1,5% of protein;
