During the Spring Festival, the movie "Hot and Hot" aroused heated discussions on the topic of **. The heroine of the movie, Le Ying, and her actor Jia Ling have achieved significant weight loss through exercise, some people praise it, and some people question it. Jia Ling lost 100 pounds in a year, is there any reference value for ordinary people? What causes obesity? In addition to reasonable diet and scientific activities, is there a "shortcut" that is not so "painful"? With these questions in mind, the reporter interviewed sports science experts.
Liu Meng, deputy director of the Chongqing Institute of Sports Science, said: "Jia Ling's basal weight before ** is larger, the ** cycle is longer, and it is normal to achieve such an effect under scientific guidance." Peng Li, a professor at the School of Physical Education of Southwest University, also believes that Jia Ling's case can be replicated by ordinary people, because the most appropriate weight loss rate is to lose 1 to 2 pounds per week, 52 weeks a year, according to the rate of losing 2 pounds per week, people with large weight can lose 104 pounds.
Experts say that the essence of obesity is that consumption is less than intake (except for obesity due to specific diseases). Therefore, the basic principle of ** is to reduce calorie intake and increase caloric expenditure at the same time, so that energy is negatively balanced.
Proper diet and exercise are the only ways to be healthy. Peng Li said that the so-called "shortcuts" advertised by some ** products actually follow the principle of negative balance of body energy. For example, some products suppress appetite to reduce calorie intake; Some drugs that claim to defecate with oil and defecation actually reduce calorie intake by speeding up the speed of food excretion or accelerating the dissolution and excretion of fat in food; There are also some ** drugs that are pro-metabolic drugs, which promote thermogenesis and lipolysis of adipose tissue by increasing central excitation, increase the body's metabolic rate, and increase calorie consumption. "But long-term use of ** medicine can lead to physical dysfunction and damage to health. Peng Li reminded.
Some people will complain that they are "easy to gain weight", and it is difficult to **. In this regard, experts said that obesity-prone physique does exist, usually related to genetics, but some people's obesity is due to their lifestyle, not physique. Liu Meng said that most obese people are late-onset obesity, which is to gradually gain weight with age, increased work pressure and busy life. Poor living habits, eating too much and moving less, or not eating too much but eating an unscientific diet are the real reasons for "easy to get fat".
For people with ** needs, experts suggest that they "keep their mouths shut and open their legs", and build a healthy body step by step in a down-to-earth manner: first make a short, medium and long-term plan, including action methods and phased goals; Then establish a healthy daily routine, including a relatively fixed exercise pattern and time, meal time and total calorie intake plan for the day, so that the body can metabolize and form an effective energy cycle.
Experts remind that a reasonable diet is not equal to dieting, but to develop a reasonable dietary structure, should adhere to the "low-fat, low-carb, high-protein, high-dietary fiber" dietary structure, large weight people can also reduce the total dietary calorie intake by eating two meals a day, or fasting for 1 to 2 days a week. In terms of physical activity, you should insist on 3 to 5 times a week for more than 30 minutes of low-to-medium intensity exercise, aerobic exercise and resistance training to increase calorie expenditure and improve muscle mass.
*After the effect is achieved, it is necessary to stick to a good diet and exercise habits to maintain a healthy body. Peng Li said.
