This is similar to a starvation period. In fact, glucose is the main metabolite of both brain and muscle. The body stores less than a day's supply of carbohydrate, thus, the less blood sugar resulting from even an overnight fast results, through an increase in glucagon secretion and a decrease of insulin secreted into blood current. With this events, fatty acids are movilized from adipose tissue and glucose uptake by muscle tissue is inhibited by insulin levels. Therefore, muscles switch from glucose to fatty acid metabolism for energy production. However, the brain remains heavily dependent on glucose.
In animal metabolism, glucose cannot be sinthesized from fatty acids, because neither pyruvate nor oxalacetate, the precursors of glucose in gluconeogenesis pathway, can be sinthesized from acetyl-CoA . During starvation, glucose therefore must be sinthesized from the glycerol product of triacylglycerol breakdown and, more importantly, from the amino acids derived from the proteolytic degradation of proteins mainly from muscles. The continued breakdown of muscle proteins during long starvation periods would ensure that this process became irreversible since a large muscle mass is essential for an animal to move about in search of food.
Starvation ensues when the fat reserves are completely exhausted and protein is the only fuel source available to the body.
About 20–30 g of protein is broken down each day to make 10 g of glucose to keep the brain alive. However, this number may decrease the longer the fasting period is continued in order to conserve protein.
The human starvation response is unique among animals in that human brains do not require the ingestion of glucose to function.
Because the human brain can use ketone bodies as major fuel sources, the body is not forced to break down skeletal muscles at a high rate, thereby maintaining both thinking and mobility for several weeks.
This response is important in human evolution and allowed for humans to continue to find food even in the face of prolonged starvation
Carbohydrates
Vary your diet--get enough protein, vegetables and fruit, and complex carbohydrates. Ditch refined carbohydrates, and artificial chemicals. Minimize animal fat.
carbohydrates
Protein is a very important component of an infant's diet. Their diet should consist of .7 to 1 gram of protein per pound of body weight. Protein should contribute 20% to an infant's diet while carbohydrates and fat account for 30-50%.
All carbohydrates are bad for you. They turn into sugar in your body. Go on a low carb diet. If your protein content is higher than the carbohyrate content then it is very good for you.
A complete diet is one that is balanced and gives you the daily recommended nutrients that your body requires. A complete diet consists of protein, good fats and good carbohydrates, vitamins, minerals and water.
more carbohydrates less protein
Protein, complex carbohydrates, vitamins and minerals.
Protein, meats.
I like to be protein because protein is good for you and make muscle carbohydrate and the other hand make fat in your body if you want to do diet cut the carb specially after 5pm
Atkins diet is a low carbohydrate diet to loose weight. The argument for the diet is that the body burns first carbohydrates in the food and goes to burn fat and proteins next. If we take less carbohydrates and more fat and protein, the body burns fat efficiently thereby allowing us to loose weight. For more on this we can visit: www.webmd.com/diet/Atkins-diet-what-it-is
The main component of the American Eskimo diet is protein. This diet is rich in protein such as fish, deer, walrus and whale. Their diet is low in carbohydrates.
