The principle of weight loss and fat reduction

1, the seven essential elements of the human body? Carbohydrates, fats, proteins, vitamins, trace elements, crude fiber, water

2. Composition and proportion of body weight? Water makes up 55% of your body's weight Fat makes up 20% of your body's weight protein makes up 5% of your body's weight Inorganic salts

3. 1g heat of the three major energy substances? 1g carbohydrate ≈4 calories 1g fat ≈9 calories 1g protein ≈4 calories

What is the law of Conservation of energy? When the body's energy intake and energy consumption reach a balance, that is, energy conservation. For example: when a person consumes 5000 kcal, consumes 2000 kcal, saves 3000 kcal ÷9, that is, increased fat weight. Intake 2000 kcal, consumption 6000 kcal, the body provides 4000 kcal ÷9, that is, lost fat weight.

5, the three major energy substances of the human body and their consumption rate? Of the seven essential elements of the human body, only three are energy, which are carbohydrates, fats, and proteins. They are called: the most active carbohydrates, functional fat and fear of burning protein. In the normal consumption process of the human body, the first consumption is carbohydrates, followed by fat, the consumption of both must be catalyzed by enzymes and coenzymes in order to carry out, in the absence of enzyme catalysis will burn protein.

6. Is obesity undernutrition or overnutrition? 95% of obesity is due to high calorie intake and lack of a variety of nutritional factors, including the necessary catalyst for lipolysis. Therefore, in clinical obesity is a typical manifestation of "modern malnutrition syndrome". Nutrition that obese people need to supplement: Supplement 38 nutrients as a necessary catalyst for lipolysis; Supplement gastric emptying, intestinal absorption, fat transport, liver metabolism, mitochondria oxidation, target cell energy-consuming functional nutrition factors; Add enough nutrients to maintain the level of metabolism, at least 58 functional nutrients are required to ensure the effective breakdown of fat at a low calorie intake.

7, the three essential conditions for healthy weight loss? Negative energy balance, low sugar, comprehensive nutrition

8, how to detect weight loss is fat? 1. Body fat scale, see the data show 2. Use urine ketone test paper, urine ketone is the product of fat decomposition, if the decomposition is fat, it can detect urine ketone.

9. Where did all the fat go? The three major excretion pathways of the human body: lungs - gas and water, skin - water, salt, a small amount of urea, etc. Kidneys - water, urea, creatinine, drugs, etc. Fat can only be converted by chemical reactions into carbon dioxide, water, and ATP, which are excreted through the lungs and consumed by the body's cells for nutrients.

10. Aerobic oxidation of fat? In the condition of sufficient oxygen supply, fatty acids can be decomposed into acetyl CoA, which is completely oxidized to CO2 and H2O and releases a large amount of energy. Most tissues can oxidize fatty acids, except brain tissues, because fatty acids cannot pass the blood-brain barrier. The specific steps of oxidation are as follows: 1) activation of fatty acids to generate fatty acyl CoA. 2) Fatty acyl CoA enters the mitochondria because the beta-oxidation of fatty acids takes place in the mitochondria. This step requires carnitine transport. Carnitine fatty acyl transferase I is the rate-limiting enzyme of fatty acid β oxidation, and the entry of fatty acyl CoA into mitochondria is the main rate-limiting step of fatty acid β-oxidation. For example, when sugar supply is insufficient in starvation, the activity of this enzyme is enhanced, and the oxidation of fatty acids is enhanced, and the body relies on fatty acids for energy supply. 3) The last β oxidation of the fatty acid beta-butyryl CoA: 2 molecules of acetyl CoA are generated, so each β oxidation of 1 molecule of fatty acyl CoA generates 1 molecule of FADH2, 1 molecule of NADH+H+, 1 molecule of acetyl CoA, and the former generates 1.5 molecules of ATP through the respiratory chain oxidation, and the latter generates 2.5 molecules of ATP.
