THANK YOU!!!!!!!!!!!!!!!!!!!!!!What is the main function of carbs?store fat, provide energy, gain weight, or control weight?
The main function of carbs are to provide energy. You have to fuel your body with calories - it can be with carbs or fat or both.





Your body requires fats %26amp; protein, you will die without them. You will die if you eat protein without fat. You do not require carbohydrates. The body can manufacture all it needs from the protein/fat combination.





A low carbohydrate diet is a high fat diet. The protein should only be a little higher than adequate. Although it is completely possible to live on a fat/protein only diet for long term (as proven by research done in a hospital setting) it becomes boring fairly quickly. Luckily many vegetables %26amp; some fruits, nuts %26amp; seeds are low in carbs and greatly expand the diet. Most long term low carbers eat as many, if not more non starchy vegetables than vegetarians.





Glucose is the bodies preferred fuel (if you want to get technical, it actually burns alcohol most efficiently, but that doesn't make it any healthier for the body than carbs), the body can convert 100% of carbs, 58% of protein %26amp; 10% of dietary fat into glucose. The body can also be fueled by fat (dietary fat %26amp; fat cells) but only in the absence of carbs. Your brain actually prefers (* reference info) to be fueled by ketones (part of the fat burning process), only the heart requires glucose, but glucose can be easily converted from fat stores or excess protein if needed or dietary fat.





IF a person eats sufficient fat %26amp; protein %26amp; minimal carbs, they can become very healthy. Free of blood sugar health problems, high blood pressure, health problems associated with high cholesterol, obesity health problems. (Cancer is fueled by glucose, if your body is not fueled by glucose, it doesn't seem to be possible to have cancer, but that is just speculation) Anything less that 9 grams of carbs per hour controls insulin and is considered low carb (up to 144 grams per day).





High fat, adequate protein and very low carbs will after 3 days convert your body from glycolysis (burning glucose for fuel) to burning fat (dietary %26amp; body fat) as fuel (ketosis). While in ketosis you will burn dietary fat and if dietary fat is more than sufficient, body fat directly. High calories will keep the metabolism at maximum fat burning capabilities. During this time the body will go through carb withdrawals, but by the 4th day you will be free of sugar addictions. The first week or so of this conversion process a person feels weak, sluggish, headachy but after this is over, most comment that they feel better %26amp; have more energy than ever before. They eat foods for nutrition %26amp; fuel %26amp; their bodies crave vegetables %26amp; fruits.





Metabolism is controlled by nutrition. You can't eat 600 or 2000 calories of fruit, your body will treat it as being starved (which it is, starved of nutrition) %26amp; will shut down your metabolism as if you're eating nothing, but will store every possible ounce as fat. You may lose water weight %26amp; lean tissue the body strips for nutrition, but that makes fat storage more efficient. Inversely, you wont gain weight on 5000 or more calories of fat %26amp; protein (if fat is 65% of calories) because insulin (the fat storage hormone) is not activated.





Eating carbohydrates while trying to lose body fat is terribly inefficient. When in glycolysis (burning glucose as fuel) you have to lower your calories (which slows your metabolism) %26amp; exercise heavily to deplete your glycogen stores before burning body fat.





Simple carbohydrates (sugar, flour, bread, cereal, pasta, potatoes, rice) triggers insulin which can store the calories you eat into fat. The more protein you eat the more the fat burning hormone glucagon is released.





High insulin levels unbalance other hormones. Controlling your insulin level will balance out other hormones %26amp; allow human growth hormone (HGH) to be produced naturally so you will gain lean muscle even without exercise.

The brain gets its energy from ketone bodies when insufficient glucose is available. After blood glucose is lowered for 3 days, the brain gets 30% of its energy from ketone bodies. After 40 days, this goes up to 70% (during the initial stages the brain does not burn ketones, since they are an important substrate for lipid synthesis in the brain). In time the brain reduces its glucose requirements from 120g to 40g per day.What is the main function of carbs?store fat, provide energy, gain weight, or control weight?
It depends on how many you eat. It's used primarily for energy when your body is the anaerobic zone. But the same as with protein and fat, if you eat more than you burn/use, it will turn into stored fat.
