Dieting to lose weight a few days before weight loss

Dieting for weight loss works very fast, generally 1-7 days to be able to see the weight loss. Dieting to lose weight, is to fully diet to achieve the purpose of weight loss, its daily caloric intake to be far below the caloric needs of people, the highest can not exceed the basic calories, but the weight loss, at first is not fat, but the body's water, followed by muscle, and finally body fat, so dieting to lose fat is very weak, but will lose more water and muscle, reducing the body's immunity .

Why dieting does not lose weight anymore

The body gradually adapts to low consumption and low calorie intake, and the brain turns on low metabolic mode, so weight loss enters a bottleneck. Generally the first two weeks of dieting for weight loss weight drops sharply, but after the fourth and fifth week, the weight will be in place, because the first two weeks of dieting, because the calorie intake is strictly controlled, while the calorie consumption is carried out as usual, resulting in the calorie people are not enough, then the body only has to use the body fat, so that it is converted into heat to meet the needs of the body to survive. Therefore, the weight of the person at this stage is really down, plus the water stored in the body of the obese person is also discharged, the weight is therefore down more powerful. But in the fourth and fifth week, the calorie intake not only continues to reduce, but also the metabolism of the body tends to slow down, and the calorie consumption in the body is also less, forming a stagnant period in which the weight is not increased nor reduced. The best way is to continue dieting to lose weight, while supplemented by exercise therapy to strengthen the speed of the body's metabolism to consume body fat, then the weight loss stagnation period will soon rush past.

Dieting weight loss how to prevent rebound

1. abstain from high-fat, high-sugar, high-salt foods

Dieting to lose weight without rebound, then we must adjust the diet structure, reduce the intake of high fat fat, high refined sugar food and high salt, maintain the intake of high quality fat, protein and vitamins, inorganic salts and other nutrients, maintain a certain caloric intake, so as to avoid the body muscle loss and lower the basal metabolism.

2. Dieting and exercise at the same time

In the diet at the same time, also need to carry out anaerobic and aerobic exercise. Anaerobic exercise can grow muscle, increase basal metabolism, so that you become susceptible body; aerobic exercise can burn calories, reduce fat, play the role of fat loss and shaping.

Why do not advocate dieting to lose weight

Because short-term concentrated dieting to lose weight can bring the following hazards.

1, will reduce immunity and basal metabolic rate

People on a diet will completely reject fat, resulting in a shortage of fat-soluble vitamins such as vitamin A, vitamin D, vitamin E, and vitamin K. This will not maintain the normal functioning of the immune system, resulting in low immunity, making it easy for various diseases to ensue. Basal metabolic rate is the amount of calories people burn in a quiet state. Extreme dieting can decrease the basal metabolic rate and lead to sudden weight gain.

2. It can cause an increase in ketone bodies and symptoms of dehydration

Strict control of carbohydrate intake will produce a large amount of ketone bodies in the process of burning fatty acids, which is very effective but may cause bad breath and vomiting, and even irreversible damage to the kidneys and liver. Glycogen accumulates in the body and is rich in water. When the body is low on energy, glycogen is consumed quickly, and water is also excreted. When you eat again, your body replenishes glycogen in large quantities and accumulates water, thus increasing your weight. This means that dieting can cause dehydration, as well as vertigo and headaches.

3. Increase the burden on the heart and damage the skin

Dieting can lower cholesterol, blood pressure, and blood sugar, which is a significant effect, but there are significant risks. The extreme reduction of calorie intake will increase the fat around the heart, increasing the burden on the heart. Dieting can also limit the intake of vitamins and minerals, causing malnutrition, premature graying of hair, loss of hair luster or hair loss, and even dry skin and acne.

4, poor bowel movement and mood irritability

Extreme dieting without a normal diet to take in nutrients, thus disrupting the movement of the gastrointestinal tract, not enough food to promote gastrointestinal peristalsis, prone to constipation, in addition to increasing the psychological pressure, so that the mood becomes more irritable and depressed, stimulating the secretion of corticosterone in the brain, but also cause low concentration and difficulty sleeping.

5, cause gastrointestinal diseases

Secondly, if the gastrointestinal tract is in a long-term starvation state with unlimited dieting, it will cause gastrointestinal dysfunction, which will easily lead to chronic gastritis, gastric ulcer, gallbladder stones, intestinal flora imbalance, malnutrition, etc. Excessive dieting will cause patients to have an urgent need for high-calorie food or no desire for food, and binge eating disorder or anorexia.
