<h1>Metabolism</h1>

It is named for the whole complicated set of physical-chemical and biological processes are nutrition and generate energy in the body.

The living being, as well as vitamins, minerals and water and minimal wear to replenish proteins, requires an amount of calories equivalent to those produced by being oxidized, burned fats, carbohydrates and proteins themselves entering with food.

On average, an adult at rest and fasting, exudes a kilocalorie or "large calorie", per kilogram of weight and time. But this amount increases with the influence of different factors: sex, height, age, constitution, environment, and especially exercise.

For you see the value of exercise in energy production, see these rough data calculated for a normal adult:

At rest                                                    1400-1500 calories

Life complete sedentary                      1900-2000 calories

Job Light (writer)                                 2100-2000 calories

Job medium (mechanical)                   2700-2800 calories

Job heavy (load and

Job heavy

(Charger Dock)                                     3600-3900 calories

If the heat release is higher than income food we have produced, the body slimming. Otherwise fattening.

In general, we can balance the balance in two ways:

a) Either reducing food intake to be stored for not being able to stay over after burning energy needs (calories).

b) Or, in other words, increasing the heat release, increasing metabolism, for example, active exercise.

c) Or a combination of both procedures.

Here is an outline to organize the weight maintenance plan

In addition, we know that:

1 gram of fat (oils, tallow, lard, etc.). Produce 9,3 lime. approx.

1 gram carbohydrates (starches, flours, sugar, etc.). Produce 4,1 lime. approx.

1 gram of albuminous (proteins) (meat, eggs, fish) produces 4,3 lime. approx.

Given that our body constantly removed nitrogen as early ureas, and that this element is only contain the protein, is necessary replacement of that loss with these to prevent antofagia.

The minimum protein is considered by physiologists 1 gram per kilogram body weight daily. This fact, together with what we have said about calorie consumption 1 kilo and hour under basal calls (fast idle) allows us to set a power type.

For a normal individual, healthy, about 65 kilos of weight, assuming that its regular method develops life or current moderate exercise, you will need about 2,600 and 2,800 calories a minimum of 70 grams protein.

Calories could supply them with 300 grams of fat or with 650-670 grams of carbohydrates, but other than that those diets unilateral, exclusive, no need to bring with us the minimum protein, we also would be indigestible and monotonous.

If power to the base only did albumins, really minimal exceed protein, but not be easily digested large amounts (on the other hand, poorly used) of albumins would be needed to meet the caloric requirements to achieve (up to 650 grams) , and might disturb not only the digestive, if not other organs - especially kidneys - apart from the diet in this form devoid of the vitamins and minerals needed also.

Therefore, a diet should always be mixed and as such amount shall contain 48 to 50% of carbohydrates, the remainder being shared between fat (25 -38%) and protein (14 -25%), so that calories contribute at a rate of 2/5 of the total with the first, other 2/5 or something else with the rest fats and protein, these must have a minimum of 70 grams.

For adult weight of 65 kilos, to which we referred, with a life subjected to moderate exercise (that requires 2600-2800 calories) your bill will be approximately:

                                              

                                                    Weight                                              calories

Carbohydrates                         210-220 gr. (50%)                           2/5 - (900 -1000)

Fats                                         120-125 gr. (25 -35%)                     2/5 - (1100-1200)

Protein                                       70-125 gr. (15 -25%)                     1/5 - (300 -600)

Total                                        400-465 gr. (100%)                          5/5 - (2300 -2800)

And of course is: who wants to lose weight should decrease the amounts, and proceed in reverse, which need to be thin to improve your weight, taking into account:

That proteins should not decrease below 70 grams.

That fat after being chemically unfolded by the digestive process, partly burn - fat energy - and partly stored - reserve fat -. (In obese may be a metabolic disturbance whereby nearly all the fats would become reservation.)

That carbohydrates, also disintegrated by digestion, in part, supply calories and the rest replenishes liver glycogen and muscles, but intervening in the metabolism of fats (which, without carbohydrates, would trigger the formation of ketone bodies: acetone and acidosis) contribute so very direct to fatness, both or more that fats same.

"In conclusion"

The metabolism may have a negative balance, normal or positive.

Should be examined frequently and critical look at the mirror and on the scale, to know which is the case of each.

negative balance

The fat that is formed under the skin is low (it is ascertained fingers catching a fold of skin large abdomen), decreasing the contribution be lower metabolic destruction (lack of income requires consumption of booking) : The individual is decidedly thin: lose weight gradually.

Normal Balance

Both processes - supply and destruction - is in equilibrium. The body is provided. The weight remains constant or with small ups and downs.

positive balance

The fat tends to increase contribution wholesale destruction. The individual fat gradually. Its weight is increased even more.
