Active physical exercise is an important method to prevent obesity at an early stage. The time and content of exercise are very important to prevent obesity.

First of all, the exercise time should be 16 to 2 1 every day, and 7-8 pm is the best. Because at this time, exercise can consume the energy consumed by dinner and prevent the accumulation of energy after eating and sleeping. In addition, all the extra calories in a day are consumed, so you will never get fat.

Secondly, the content of sports is mainly natural and interesting chronic sports, such as walking, jogging, playing ball, skipping rope, active games and other outdoor activities.

The key 30 minutes will make you lose weight quickly.

Losing weight does not necessarily reduce body fat. The key to reducing fat is to start 30 minutes after meals. What is the reason for it? What should I do in these 30 minutes to effectively reduce body fat?

Recently, medical obesity is not only measured by weight, but by the proportion of fat to weight. The general standard is to use 25% of male body fat and 30% of female body fat. Therefore, even if someone is overweight, but the body fat rate is only 20%, it can not be called obesity; Conversely, if the weight is below the standard, but the body fat rate is above 30%, it can also be called obesity.

Fat is the chief culprit of chronic diseases.

Although the fat caught near the waist is visible, it will not cause much health problems. The problem is visceral fat. Visceral fat is attached to the abdomen and gastrointestinal tract, which is one of the causes of chronic diseases such as diabetes and hypertension. Because once fat cells get bigger, they will secrete substances that cause hypertension, hyperlipidemia and diabetes.

30 minutes is everything.

The three main reasons for losing weight are: it seems that there is no effect, living habits have changed greatly, psychological pressure is great, and health is poor.

How can we prevent fat from getting on the upper body? The most effective method is aerobic exercise If you really can't do it, at least don't let the blood sugar concentration rise after meals. If you don't want to grow fatter than you are now, the first thing to do is to exercise after meals. Because the small intestine begins to absorb about 30 minutes after eating, and the blood sugar concentration rises about 30 minutes after the small intestine begins to absorb.

Recently, a study published by the Cooper Institute of Aerobic Exercise in the United States found that people who consciously exercise in their daily lives lose almost the same weight and body fat as those who swim or ride bicycles for 20 to 60 minutes every day for six months and five days a week. The same study found that daily life consumes more calories than expected.

First, it is not suitable for exercise for a period of time after meals.

Reason:

1, the increase of insulin secretion after meals can inhibit lipolysis, and the energy source is limited. Because there is less fat decomposition, it is not appropriate to carry out weight loss exercise at this time.

2, stimulate the stomach: exercise after eating a full meal will bring mechanical stimulation to the stomach, so that the dissolved matter in the stomach will vibrate left and right, up and down, which is easy to cause vomiting, stomach cramps and other symptoms.

3, affecting the effect of weight loss exercise: after eating, the parasympathetic nerves in the body are easily suppressed. If the body wants to exercise, the exercise effect will be discounted.

4, blood flow distribution disorder: after eating a full meal, the digestive organs need a lot of blood for digestion and absorption, and the whole body muscles also need a lot of blood to participate in exercise, so it will seize the blood capacity of the digestive organs, leading to digestive and absorption dysfunction, not only affecting the exercise effect, but also causing harm to the body.

Second, the best time to lose weight in a day

The study found that light exercise for one hour after meals is the most reasonable; Moderate exercise should be arranged two hours after meals; You can do high-intensity exercise three hours after dinner. Based on this, several optimal exercise periods can be deduced:

Morning session: 3 hours after breakfast to before lunch.

Afternoon: 3 hours after lunch to before dinner.

Evening session: 3 hours after dinner to bedtime.
