Jia Ling lost 50 kilograms of fat through boxing! Doctor Liu Boen: 4 points to note when losing weight with boxing

Recently, 41-year-old mainland actress Jia Ling directed and starred in the movie "Hot and Spicy". She accidentally lost nearly 50 kilograms of fat in one year with the help of boxing and following the "168 intermittent fasting method" principles, which caused a boxing craze in mainland China. Many people tried various boxing methods to achieve the goal of losing weight. Liu Bowen, a domestic obesity specialist and weight loss physician, said that boxing can increase metabolic rate, help lose weight, and has other benefits.

Liu Bowen, a bariatric physician specializing in obesity, said that from a medical point of view, boxing can burn about 13 calories per minute, which does have a higher CP value than aerobic exercises such as running or cycling. In the past, the purpose of practicing boxing was to focus on muscle strength training, but due to the increase in oxygen consumption, it can also increase the metabolic rate, indirectly achieving the additional effects of burning calories and losing weight.

Boxing has the following 5 benefits

Boxing has the following five benefits:

1. Increase muscle mass: Boxing can effectively increase muscle content and muscle strength, thereby tightening the muscles and achieving the effect of body shaping.

2. Improve metabolism: In boxing, the metabolic rate is also improved, thus achieving the effect of mass decomposition and weight loss.

3. Improve cardiopulmonary function: During boxing, due to the high oxygen consumption, it is a medium to high level aerobic exercise, which can improve cardiopulmonary function.

4. Improve thinking concentration: It can improve thinking concentration, because it can increase nutrient concentration in a short time, and then it can also promote the concentration of endorphins, achieving the effect of "happy" mood.

5. Build muscle and reduce fat: It can tighten the pectoralis major and upper arm muscles in the upper body, achieving the effect of building muscle and reducing fat.

Boxing exercise can effectively increase muscle content and muscle strength, thereby making the muscles firm and achieving the effect of body shaping.

4 points to note when losing weight with boxing

However, Dr. Liu Bowen reminds that if you want to lose weight through boxing exercise, you should pay special attention to the following 4 points:

1. Do warm-up exercises first: Be sure to do some warm-up exercises before doing boxing exercises to avoid some boxing exercises with too high intensity, which may cause sports injuries to the wrist muscles and joints.

2. Protect your head: If you are participating in a boxing match, you should also pay attention to head protection measures to avoid traumatic brain damage.

3. Do not drink carbonated drinks after exercise: After boxing, do not consume too many carbonated drinks, otherwise the GI value will soar instantly, which will make it easier to store more calories.

4. Supplement protein before exercise: About 1 hour before exercise, you can add some high CP value protein food, which can not only supplement calories, but also serve as raw materials for muscle building.

If you already have a muscular body, you should avoid the problem of becoming even more "firm" due to over-training of your muscles.

For those who already have cardiovascular disease, they should ask a doctor for evaluation before doing boxing-style weight loss exercises to avoid the risk of accidental shock.

As for the boxing exercise model, it also requires the intervention of professional exercise prescriptions to achieve twice the result with half the effort.

People who use 168 intermittent fasting for a long time may experience fatigue, lack of concentration, and anxiety if they do not consume enough nutrients needed by the body.

168 Blind Spots of Fasting Weight Loss Method

In addition to boxing, Jia Ling recently revealed her diet during an interview: Chinese cabbage, purple cabbage, bell peppers, chicken breast, brown rice, and she maintains "less oil and less salt, 20 grams of oil and 5 grams of salt a day", and follows the "168 intermittent fasting method" principle, trying to finish eating within 8 hours.

However, Dr. Liu Boen pointed out that the 168-hour fasting diet has the following blind spots:

1. If the total calories for the whole day remain unchanged and need to be completed within 8 hours, the physiological functions may not be able to complete the functions of full digestion and absorption in this short time.

2. The average person's stomach emptying time is about 4 hours. Excluding 8 hours for sleep and rest, there are still 8 hours in the fasting state, which may increase gastric acid secretion and worsen hypoglycemia, causing blood sugar to drop, affecting normal physiological functions, and in the long run affecting endocrine changes.

Problems with long-term intermittent fasting

It should be noted that people who use 168 intermittent fasting for a long time may experience fatigue, lack of concentration, and anxiety if they do not take in enough nutrients the body needs. Especially for those who are diabetics or have poor stomach function, it is not suitable to use the 168 intermittent fasting weight loss method for a long time.

When you first start doing 168 intermittent fasting, you may lose weight due to the novelty or the power of will. But after a period of time, you will consume a large amount of food, even excessive amounts of food, in a short period of time to achieve a feeling of fullness. Therefore, although the eating time is shorter, the total amount has increased, so that after a period of time, the weight is easily gained back.
